6 2. Security notes Device may ony be disposed in a professiona manner! The instaation and commissioning shoud ony be carried out by trained personne. Check the foowing points before commissioning: that the maximum vaues for a the connections are not exceeded, see "Technica data" section, that the connection wires are not damaged, and that they are not ive during wiring, that the power fow direction and the phase rotation are correct. The instrument must be taken out of service if safe operation is no onger possibe (e.g. visibe damage). In this case, a the connections must be switched off. The instrument must be returned to the factory or to an authorized service deaer. It is forbidden to open the housing and to make modifications to the instrument. The instrument is not equipped with an integrated circuit breaker. During instaation check that a abeed switch is instaed and that it can easiy be reached by the operators. Unauthorized repair or ateration of the unit invaidates the warranty. 3. Device overview 3.1 Brief description The APLUS is a comprehensive instrument for the universa measurement, monitoring and power quaity anaysis in power systems. The device can be adapted fast and easiy to the measurement task by means of the CB-Manager software. The universa measurement system of the device may be used directy for any power system, from singe phase up to 4-wire unbaanced networks, without hardware modifications. Independent of measurement task and outer infuences aways the same high performance is achieved. Using additiona, optiona components the opportunities of the APLUS may be extended. You may choose from I/O extensions, communication interfaces, Rogowski current inputs or data ogger. The namepate on the device gives further detais about the present version. 6/69 Device handbook APLUS with TFT dispay, , 04/2016

7 3.2 Possibe modes of operation The APLUS can cover a wide range of possibe input ranges without any hardware variance. The adaption to the input signa is performed by means of variabe ampifying eves for current and votage inputs. Depending on the appication it makes sense to fix these eves by means of the configuration or to et them stay variabe to achieve a maximum accuracy during measurement. The differentiation, if the ampifying remains constant or is adapted to the present vaue, is done during the definition of the input configuration by means of the parameter "auto-scaing". The disadvantage of auto-scaing is that when an ampifying eve needs to be changed, a setting time of at east one cyce of the power frequency must be aowed unti the signas have stabiized again. During this short time the measurement resuts remain frozen. Continuous measurement An absoute uninterrupted measurement of a quantities assumes that auto-scaing is deactivated for both votage and current inputs. Metering The uncertainty of the active energy meters of the APLUS is given with cass 0.5S. To fufi the high requirements of the underying meter standard EN aso sma currents have to be measured very accurate. To do so, auto-scaing must be activated for current inputs. For metering appications the system votage is assumed to be quite constant, nomina vaue acc. standard, wherefore auto-scaing for votages is not required. The subsequent exampe shows an appropriate configuration, which aso conforms to the factory setting of the device. Dynamic monitoring of imit vaues An important criterion when monitoring the quaity of the suppy votage is the possibiity to detect short sags of the system votage. To be abe to foow the progress of the votage auto-scaing of the votage inputs shoud be deactivated. Thereby you have to consider that a possibe swe of the votage may be detected ony up to the configured overriding (20% of rated votage in the above exampe), because the switching of the measurement range is ocked in both directions. This appies anaogousy to a quantities of the system, whose progress shoud be monitored. For power quantities the votage ampification as we as the current ampification is infuenced. However, which basic quantities may vary how much can differ from appication to appication. 7/69 Device handbook APLUS with TFT dispay, , 04/2016

8 3.3 Monitoring and aarming The ogic modue integrated in the APLUS is a powerfu feature to monitor critica situations without deay on device side. By impementing this oca inteigence a safe monitoring can be reaized which is independent of the readiness of the contro system Aarming concept How aarms are handed is decided during the configuration of the device. For that in the ogic modue you can define if aarm states wi be dispayed on the TFT dispay and how resp. when a possiby activated action, such as the switching of a reay, wi be reset. These configuration parameters are highighted in yeow in the foowing chart. ALARM Perform action Y Action configurated? TFT used for aarm dispay? Y Fashing menu Aarm in ist ON Action resettabe? N Y N No action N Aarm state sti persists? N Aarm in ist OFF Y Aarm state sti persists? Y N Action reset Y Reset? N Aarm ist dispayed? N Y Norma menu Aarm reset: This procedure affects the states of the foow-up actions If an aarm state occurs a foow-up action (e.g. the switching of a reay) can be triggered. This foow-up action is normay reset as soon as the aarm condition no onger exists. But the aarm handing may be configured as we in a way that ony by means of an aarm reset the subsequent operation is withdrawn. This way an aarm remains stored unti a reset is performed, even if the aarm situation no onger exists. Possibe sources for an aarm reset are the dispay, a digita input, another ogica state of the ogic modue or a command via the bus interface. On the next page some signa fow exampes are shown. 8/69 Device handbook APLUS with TFT dispay, , 04/2016

10 3.3.2 Logic components The ogic outputs are cacuated via a two eve ogica combination of states, which are present at the inputs. Usabe components are AND, OR and XOR gates as we as their inversions NAND, NOR and XNOR. The principa function of the ogica gates is given in the foowing tabe, for simpicity shown for gates with two inputs ony. function AND NAND OR NOR XOR XNOR symbo oder symbos ANSI DIN (at) truth tabe A B Y A B Y A B Y A B Y A B Y A B Y pain text Function is true if a input conditions are fufied Function is true if at east one of the input conditions is not fufied Function is true if at east one of the input conditions is fufied Function is true if none of the input conditions is fufied Function is true if exacty one of the input conditions is fufied Function is true if a of the input conditions are fufied or a conditions are not fufied The ogic components of the first eve may combine up to three, the components of the second eve up to four input conditions. If individua inputs are not used, their state is automaticay set to a condition which has no infuence on the ogic resut. 10/69 Device handbook APLUS with TFT dispay, , 04/2016

11 3.3.3 Limit vaues States of imit vaues are the most important input quantities of the ogic modue. Depending on the appication, imits either monitor the exceeding of a given vaue (upper imit) or the fa beow a given vaue (ower imit). Limits are defined by means of two parameters, the imit for the ON and the imit for the OFF state. The hysteresis is the difference between these two vaues. Upper imit: The imit for ON state (L.On) is higher than the imit for the OFF state (L.OFF) Limit for ON state Limit for OFF state Limit state 0 1 The state 1 (true) resuts if the imit for ON state is exceeded. It remains unti the vaue fas beow the imit for OFF state again. The state 0 (fase) resuts if the imit for ON state is not yet reached or if, foowing the activation of the imit vaue, the vaue fas beow the imit for OFF state again. Lower imit: The imit for ON state (L.On) is smaer than the imit for OFF state (L.OFF) Limit for OFF state Limit for ON state Limit state 0 1 The state 1 (true) resuts if the vaue fas beow the imit for ON state. It remains unti the vaue exceeds the imit for OFF state again. The state 0 (fase) resuts if the vaue is higher than the imit for ON state or if, foowing the activation of the imit vaue, the vaue exceeds the imit for OFF state again. If for a imit vaue the imit for ON state and the imit for OFF state are configured to the same vaue, it wi be treated as an upper imit vaue with a hysteresis of 0%. Limit vaues may be used to contro the running of operating hour counters. As ong as the imit vaues are fufied (ogica 1) the operating hour counters keep on running. Not ony operating times may be measured, but e.g. time under overoad condition (additiona stress) as we. 11/69 Device handbook APLUS with TFT dispay, , 04/2016

12 3.3.4 Sequence of evauation The evauation of the ogic modue is performed from top to bottom and from eft to right: 1. Y1, Y2, Y3, Y4 2. Z1, Z2, Z3, Z4 3. D1, D2, D3, D4 4. A1, A2, A3, A4 The evauation is performed once each cyce of the power frequency, e.g. every 20ms at 50Hz. But the time between two evauations wi never be onger than 25ms. If the ogica states Y1...Y4, Z1...Z4, D1...D4 and A1...A4 are used as inputs, their changed states wi be incuded in the evauation of the next interva Exception: In the first evauation eve the state of previous ogica functions may be used as input without deay, e.g. the state Y1 for the ogica functions with output Y2, Y3 or Y4. 12/69 Device handbook APLUS with TFT dispay, , 04/2016

13 3.4 Free Modbus image Accessing measured data of a Modbus device often needs some specia effort, if the interesting measurements are stored in different, non continuous register areas. This way mutipe teegrams must be sent to the device to read a data. This needs time and it's very ikey, that the measurements don't originate from the same measurement cyce. A free assemby of the data to read heps a ot. The APLUS supports, aong with the sti avaiabe cassica Modbus image with thousands of registers, the faciity to assembe two different images, which may be read with one teegram ony. These freey assembed images are refreshed after each measurement cyce and therefore aways provide the most present vaues. The free foat image Up to 60 instantaneous, mean, unbaance or THD/TDD vaues may be arranged in any sequence on the register addresses A of these vaues are foating point numbers, which aocate 2 registers per vaue. Meter vaues are not possibe because they have another format. The free integer image Some oder contro systems are not abe to hande foat vaues. To make it possibe to work with the data of the device up to Bit integer vaues can be derived from the existing measurement vaues. These vaues wi then be stored in the free Modbus image (register up to 41819) as integer vaues with seectabe range of vaues. Exampe: Current transformer 100/5A, measurement current phase 1, over range 20% The reference vaue is 120A (maximum measurabe current) The integer vaue sha be 12'000 if the measurement is 120A After seecting the measured quantity and entering the register vaue of 12'000 automaticay a scaing factor of is cacuated. The measurement I1 therefore wi be mutipied by before it is converted into an integer vaue and stored in the Modbus image. Aso in the integer image instantaneous, mean, unbaance or THD/TDD vaues may be arranged. For devices with Profibus interface the Modbus image is used for the assemby of the cycica teegram. Via Modbus the same image can be used, but it s not possibe to use it independenty. The Modbus communication of the APLUS is described in a separate document. Depending on the communication hardware seected, either the manua for Modbus/RTU or Modbus/TCP protoco shoud be used. These documents can be downoaded via our homepage W : Modbus/RTU interface APLUS (communication interface RS485) W : Modbus/TCP interface APLUS (communication interface Ethernet) 13/69 Device handbook APLUS with TFT dispay, , 04/2016

14 4. Mechanica mounting The version of the APLUS with TFT dispay is designed for pane mounting as shown beow Pease ensure that the operating temperature imits are not exceeded when determining the pace of mounting (pace of measurement): C 4.1 Pane cutout Dimensiona drawing APLUS: See section Mounting of the device The APLUS is suitabe for pane widths up to 10mm. a) Side the device into the cutout from the outside b) From the side side in the mounting camps into the intended openings and pu them back about 2 mm c) Tighten the fixation screws unti the device is tighty fixed with the pane 4.3 Demounting of the device The demounting of the device may be performed ony if a connected wires are out of service. Remove a pug-in terminas and a connections of the current and votage inputs. Pay attention to the fact, that current transformers must be shortened before removing the current connections to the device. Then demount the device in the opposite order of mounting (4.2). 14/69 Device handbook APLUS with TFT dispay, , 04/2016

17 5.4 Inputs A votage measurement inputs must originate at circuit breakers or fuses rated 10 Amps or ess. This does not appy to the neutra connector. You have to provide a method for manuay removing power from the device, such as a ceary abeed circuit breaker or a fused disconnect switch. When using votage transformers you have to ensure that their secondary connections never wi be short-circuited. No fuse may be connected upstream of the current measurement inputs! When using current transformers their secondary connectors must be short-circuited during instaation and before removing the device. Never open the secondary circuit under oad. The connection of the inputs depends on the configured system (connection type). The required device externa fusing of the votage inputs is not shown in the foowing connection diagrams.

However, instead of current transformers a Rogowski cois is paced around each current-carrying conductor. This is subsequenty shown for the measurement in a 4-wire ow-votage system. When connecting the cois you must foow the safety notices given in the operating instructions of the Rogowski coi. The current direction shown on the cois must match the rea current direction and has to be the same for a phases. In order to suppress injected interferences the shieding (green) is connected aways to the termina of the current inputs (I1-, I2- resp. I3-). 21/69 Device handbook APLUS with TFT dispay, , 04/2016

22 5.6 Power suppy A marked and easiy accessibe current imiting switch has to be arranged in the vicinity of the device for turning off the power suppy. Fusing shoud be 10 Amps or ess and must be rated for the avaiabe votage and faut current. 5.7 Reays When the device is switched off the reay contacts are de-energized, but dangerous votages may be present. The reay X2 is part of the basic unit and therefore aways avaiabe. The reays X5 and X6 are provided for device versions with I/O extension PCB ony. The pug-in terminas have different coours to prevent mixing up the connections. The pin assignment is the same for a reays: 22/69 Device handbook APLUS with TFT dispay, , 04/2016

23 5.8 Digita inputs and outputs For the digita inputs / outputs an externa power suppy of 12 / 24V DC is required. The power suppy sha not exceed 30V DC! The pug-in termina X7 is avaiabe for device versions with I/O extension PCB ony. The number of digita inputs / outputs varies depending on the optiona buit-in PCB, see namepate. The operating direction of the digita I/Os on X7 may be individuay seected by means of the PC software. The assignment of the connections depends on whether an I/O is configured to be a digita input or a digita output. Exampe Device with I/O extension 2 (2 reays + 6 digita I/Os) The digita I/Os on pug-in termina X7 are individuay programmabe as input or output. On pug-in termina X3 a digita input and a digita output are provided staticay. Their operating direction may not be modified.

Switching frequency (S0) 20 Hz Leakage current 0,01 ma Votage drop < 3 V Load capacity 400 Ω 1 MΩ Driving a counter mechanism 1) Recommended if input impedance of counter > 100 kω The width of the energy puses can be seected by means of the PC software but have to be adapted to the counter mechanism. Once a second there is a decision how many puses have to be output. Therefore the deay between two puses may not be used to determine the present power demand. Eectro mechanica meters typicay need a puse width of ms. Eectronic meters are party capabe to detect puses in the khz range. There are the types NPN (active negative edge) and PNP (active positive edge). For the APLUS a PNP type is required. The puse width has to be at east 30ms (acc. EN ). The deay between to puses corresponds at east to the puse width. The smaer the puse width, the higher the sensitivity to disturbances. 24/69 Device handbook APLUS with TFT dispay, , 04/2016

25 5.9 Anaog outputs Anaog outputs are avaiabe for devices with I/O extension 1 ony. See namepate. Connection to an anaog input card of a PLC or a contro system The APLUS is an isoated measurement device. In addition the particuar outputs are gavanicay isoated. To reduce the infuence of disturbances shieded a twisted-pair cabes shoud be used. The shied shoud be connected to earth on both opposite ends. If there a potentia differences between the ends of the cabe the shied shoud be earthed on one side ony to prevent from equaizing currents. Under a circumstances consider as we appropriate remarks in the instruction manua of the system to connect Modbus interface RS485 X4 and / or X8 Depending on the device version up to two Modbus interfaces are avaiabe on the pug-in positions X4 and / or X8. These are gavanicay isoated. The connection terminas are distinguished by coor: X4 (gray), X8 (back). 1) One ground connection ony. This is possiby made within the master (PC). Rt: Termination resistors: 120 Ω each for ong cabes (> approx. 10 m) Rs: Bus suppy resistors, 390 Ω each The signa wires (X4-1, X4-2 resp. X8-1, X8-2) have to be twisted. GND (X4-3 resp. X8-3) can be connected via a wire or via the cabe screen. In disturbed environments shieded cabes must be used. Suppy resistors (Rs) have to be present in bus master (PC) interface. Stubs shoud be avoided when connecting the devices. A pure daisy chain network is idea. You may connect up to 32 Modbus devices to each bus. A proper operation requires that a devices connected to the respective bus have equa communication settings (baud rate, transmission format) and unique Modbus addresses. If there are two Modbus interfaces, their settings may be different. The bus system is operated haf dupex and may be extended to a maximum ength of 1200 m without repeater. 25/69 Device handbook APLUS with TFT dispay, , 04/2016

26 5.11 Profibus DP interface The 9-pin DSUB socket serves the connection of a standard Profibus pug. In a bus termina device, the bus ine must be terminated with resistors in the bus pug. Then standard pin assignment is as foows: Pin Name Description 3 B RxD/TxD-P 4 RTS Request to send: CNTR-P (TTL) 5 GND Data ground 6 +5V VP 8 A RxD/TxD-N LED BF (Bus faiure, yeow) Status ON Fashing (2Hz) OFF Description Startup state or interna communication error Parameterization check faied Cycica operation; no error LED BA (Bus aive, green) Status OFF Fashing (2Hz) ON Description Startup state; no Profibus communication Profibus detected; waiting for parameterization from master Parameterization ok; Profibus communication active 26/69 Device handbook APLUS with TFT dispay, , 04/2016

27 6. Commissioning Before commissioning you have to check if the connection data of the transducer match the data of the pant (see namepate). If so, you can start to put the device into operation by switching on the power suppy and the measurement inputs. Measurement input Input votage Input current System frequency 1 Works no. 2 Test and conformity marks 3 Assignment votage inputs 4 Assignment current inputs 5 Assignment power suppy 6 Load capacity reay outputs 6.1 Software instaation CB-Manager A compete parametrization of the device is possibe via configuration interface ony, using the PC software CB-Manager. The software may be downoaded free of charge from our homepage The fie "Read-me-first" on the Doku-CD provides a necessary information for the instaation of the CB-Manager software and assistance for possibe probems. Functionaity of the CB-Manager software The software is primary a too for the configuration of different devices (APLUS, CAM, VR660, A200R, V604s) and supports the user during commissioning and service. It aows as we the reading and visuaization of measured data. Acquisition and modification of a device features Setting of rea-time cock and time zone, seection of time synchronization method Archiving of configuration and measurement fies Visuaization of present measurements Reading, setting and resetting of meters Reading and resetting of minimum/maximum vaues Starting, stopping and resetting of the optiona data ogger Recording of measurement progressions during commissioning Check for correct device connection Simuation of states or outputs to test subsequent circuits Adjust the security system as protection against unauthorized access or manipuations The CB-Manager software provides a comprehensive hep faciity, which describes in detai the operation of the software as we as a possibe parameter settings. 27/69 Device handbook APLUS with TFT dispay, , 04/2016

28 6.2 Parametrization of the device functionaity Operating the software The device configuration is divided into registers, which contain thematicay the different function bocks of the device, e.g. "input", "imit vaues", "dispay". Thereby of course there are interdependencies, which have to be considered. If e.g. a current imit vaue is defined and subsequenty the ratio of the current transformer is changed, there is a high probabiity that the imit vaue is changed as we. Therefore a meaningfu sequence must be kept during setting the parameters. The easiest way is to hande register by register and ine by ine: Device (set the device version, if not read directy from the device) If an I/O extension unit is used: Fix the data direction of the digita I/O's. Do to so just cick on the appropriate entry and change the data direction in the I/O register. So it's assured that these I/O's can be used in the intended way. If e.g. you miss to change de basic setting "digita input" the appropriate channe can't be used as output in the ogic modue. Input, especiay system and transformer ratios Mean vaues >> Limit vaues >> Logic modue >> I/O 1-3 if present: I/O 4,5 >> I/O 6,7 >> I/O 8,9 >> I/O 10,11 Operating hours if present: Logger >> Interface (Ethernet, Profibus DP) >> Dispay (TFT) Modbus-Image (if you want to define your own Modbus image) Time zone (for automatica handing of dayight saving time) 28/69 Device handbook APLUS with TFT dispay, , 04/2016

29 ONLINE / OFFLINE The parametrization may be performed ONLINE (with existing connection to the device) or OFFLINE (without connection to the device). To perform an ONLINE configuration first the configuration of the connected device, and therewith its hardware version, is read. A modified configuration can then be downoaded to the device and stored on the hard disk of the computer for archiving. An OFFLINE parametrization can be used to prepare device configurations, to store them on disk and to downoad it to the devices, once you are in the fied where the devices are instaed. To make this work, the device versions seected during parametrization must agree with the versions on site. 6.3 Instaation check Check if inputs are connected correcty Votage (at east 20% U rated ) and current (at east 2% I rated ) must be present Using the connection check, which is integrated in the visuaization of the instantaneous vaues, the correct connection of the current and votage inputs may be checked. The phase sequence wi be checked, as we as if there are open connections or reversed current connections (which change the direction of the current). The image beow shows open current connections (red description I1, I2, I3). This arises because the individua currents are beow 2% of the rated vaue. Simuation of I/O's To check if subsequent circuits wi work propery with the measurement data provided by the APLUS a anaog, digita and reay outputs may be simuated, by predefining any output vaue resp. discrete state by means of the CB-Manager software. Aso a functions of the ogic modue, which aows performing any combination of ogica states, may be predefined. This way e.g. an aarming due to a vioation of a imit vaue can be simuated. 29/69 Device handbook APLUS with TFT dispay, , 04/2016

30 6.4 Instaation of Ethernet devices Connection Before devices can be connected to an existing Ethernet network, you have to ensure that they wi not disturb the norma network service. The rue is: None of the devices to connect is aowed to have the same IP address than another device aready instaed The factory setting of the IP address of APLUS is: The standard RJ45 connector serves for direct connecting an Ethernet cabe. If the PC is directy connected to the device a cross-wired cabe must be used. The network instaation of the devices is done by means of the CB-Manager software (see 6.4.2) or directy via the oca programming on the dispay. As soon as a devices have a unique network address they may be accessed by means of a suitabe Modbus master cient. Interface: RJ45 connector, Ethernet 100BaseTX Mode: 10/100 MBit/s, fu / haf dupex, Auto-negotiation Protocos: Modbus/TCP, NTP Function of the LED's LED 1 (Green) ON as soon as a network connection exists Fashing when data is transmitted via Ethernet connection LED 2 (Orange) Fashing with 4 Hz during start-up ON during Modbus/TCP communication with the device To have a unique identification of Ethernet devices in a network, to each connection a unique MAC address is assigned. This address is given on the namepate, in the exampe AE Compared to the IP address, which may be modified by the user any time, the MAC address is staticay. 30/69 Device handbook APLUS with TFT dispay, , 04/2016

31 6.4.2 Network instaation using the CB-Manager software For the subsequent Modbus/TCP communication a unique network address must be assigned to each of the devices. This can be done very easiy, using the CB-Manager software to search for devices which have a MAC address AE-xx-xx, which identifies the device as APLUS of Camie Bauer. Because this is performed by means of a UDP broadcast teegram, the devices are aowed to have the same network address at the beginning, e.g. " " as factory defaut. As soon as to a the devices network settings with unique IP address have been assigned, they may be accessed and read using the Modbus/TCP protoco. Seect "settings" under options interface. The interface type has to be set to "TCP-IP". Devices in the oca network Set settings to "CAM, APLUS". Aong with a APLUS aso SINEAX CAM devices instaed in the same network wi be shown. The identification of the devices is possibe by means of their MAC address, which is given on the namepate (see chapter 6.4.1). To assign a unique network address to a device, seect it in the ist and the cick on "change". The foowing settings have to be arranged with the network administrator: - IP address: This one must be unique, i.e. may be assigned in the network ony once. - Subnet mask: Defines how many devices are directy addressabe in the network. This setting is equa for a the devices. - Defaut gateway: Is used to resove addresses during communication between different networks. Shoud contain a vaid address within the own network. - Hostname: Individua designation for each device. Heps to identify the device in the device ist. 31/69 Device handbook APLUS with TFT dispay, , 04/2016

32 Exampe Initia situation Instaed system IP AE AE AE MAC AE AE AE Devices outside the oca network Devices which are not in the same network as the PC (e.g. in the Internet) can not be found and have to be added manuay to the device ist by means of. The type of the device must be seected previousy. To each entry you have to assign a unique IP and MAC address, which are different from the initia vaue. Otherwise it's not possibe to add further entries. The setting of the network parameters must be performed before mounting the device. As an aternative this may be done in the destination network via Ethernet interface Network instaation by means of oca programming The network settings IP address, subnet mask and gateway can aso be configured directy via the oca programming of the APLUS on site. 32/69 Device handbook APLUS with TFT dispay, , 04/2016

33 6.4.4 Time synchronization via NTP-protoco For the time synchronization via Ethernet NTP (Network Time Protoco) is the standard. Corresponding time servers are used in computer networks, but are aso avaiabe for free via Internet. Using NTP it's possibe to hod a devices on a common time base. Two different NTP servers may be defined. If the first server is not avaiabe the second server is used for trying to synchronize the time. Adjusting of the cock is performed in the interva seected (15min. up to 24h). If no time synchronization is desired, to both NTP servers the address have to be assigned. The setting of the addresses is done by means of the CB-Manager software. The NTP data is arranged in the register "Ethernet" of the device configuration. Activation To activate the time synchronization via NTP, the "Synchronisation RTC" must be checked by means of the checkbox TCP ports for data transmission TCP ports The TCP communication is done via so-caed ports. The number of the used port aows determining the type of communication. As a standard Modbus/TCP communication is performed via TCP port 502, NTP uses port 123. However, the port for the Modbus/TCP teegrams may be modified. You may provide a unique port to each of the devices, e.g. 503, 504, 505 etc., for an easier anaysis of the teegram traffic. The setting of the Modbus TCP port is done as shown above. Independent of these setting a communication via port 502 is aways supported. The device aows at east 5 connections to different cients at the same time. Firewa Due to security reasons nowadays each network is protected by means of a firewa. When configuring the firewa you have to decide which communication is desired and which have to be bocked. The TCP port 502 for the Modbus/TCP communication normay is considered to be unsafe and is very often disabed. This may ead to a situation where no communication between networks (e.g. via Internet) is possibe. 33/69 Device handbook APLUS with TFT dispay, , 04/2016

34 6.5 Instaation of Profibus DP devices The Profibus DP interface aows data exchange with a contro system via Profibus-DP V0. The moduar device mode provides maximum protoco efficiency. Required measured variabes are determined during engineering and arranged as a fixed process image. The contro system does not require any inteigence for the evauation of the data (no tunneing protoco). Bus parameterising faciitates simpe and fast commissioning. On-site the foowing parameters can be set: - Device address - Accepting master parameterization (Check_User_Prm) - Estabishing communication to the master (Go_Onine) - Setting device address via master (Set_Save_Addr_Supp) For the assemby of the cycica Profibus teegram the Modbus image is used. Via Modbus the same image can be used, but it s no onger possibe to use it independenty. GSD parameterization Typicay the parameterization of the Profibus save is done on the contro system. During startup the APLUS adopts these settings. Doing so the parameterization of the input parameters (input system, transformer ratios etc.) as we as the assemby of the Modbus image wi be overwritten. Other parts of the configuration, such as parameterization of I/O s or settings of imit vaues, remain unchanged. A necessary informations for the parameterization are part of the DMF (GSD) fie. This one can be downoaded from our homepage The assumption of the engineered parameters can be prevented by deactivating the Check_User_Prm fag. The parameterization ocay set wi not be changed this way. Cycica data exchange The user can compose its own station with a required quantities. Up to 60 measured quantities can be moduary concatenated. You may choose from instantaneous vaues of the system and imbaance anaysis, mean-vaues of power quantities and freey seectabe quantities as we as meter vaues. Subsequent to the adoption of the parameterization, the APLUS is ready for the cycica data exchange with the contro system. 34/69 Device handbook APLUS with TFT dispay, , 04/2016

35 6.6 Protection against device data changing Data stored in the device may be modified or reset via communication interface or via the keys on the device itsef. To restrict these possibiities on-site, via CB-Manager the security system in the device can be activated (factory defaut: not activated). For the definition of these user rights in the software the input of an administrator ogin is required. The factory defaut is: user: admin password: admin The administrator password may be modified, but a reset can be performed in our factory ony! For one user via device and one user via interface (specia ogin) the access to the foowing functions can individuay be granted: Configuration of the device, modification of RTC parameters, modification of imit vaues, reset of min/max or meter vaues, aarm acknowedgment, dispay mode changing. 35/69 Device handbook APLUS with TFT dispay, , 04/2016

38 7.3 Dispay modes The device supports two assembies of measurement pages, which are arranged in form of a tabe (x/y matrix). - DEFAULT: The factory defaut assemby of measurement pages - USER: The freey defined measurement pages of the user (empty when deivered) The dispay pages to use can be changed during operation. In combination with a possibe automatic page change the user can define the dispayabe data and the behavior due to inactivity (no keys pressed by the user). Used dispay pages DEFAULT USER Automatic page change None Preferred page Loop None Preferred page Loop Behavior The user can seect images from the DEFAULT dispay pages. No automatic page change due to inactivity. The user can seect images from the USER dispay pages. No automatic page change due to inactivity. The user can seect images from the USER dispay pages. The preferred page is shown after a programmabe inactivity time. A maximum of up to 20 pages from the customer pages (USER) are dispayed endessy one after the other. The interva time fort he image change is programmabe. The USER dispay pages can be activated ony, if at east one customer dispay page has been defined! The navigation within the measurement pages is done by means of the arrow keys: One image to the eft. Most eft image of the next ine is dispayed. Most eft image of the previous ine is dispayed. One image to the right. The DEFAULT dispay matrices are shown in Annex B 38/69 Device handbook APLUS with TFT dispay, , 04/2016

39 7.4 Aarm handing How aarms are handed is fixed during the configuration of the device. A detaied description of the aarming concept is here: Monitoring und aarming Aarm state dispay on the device The dispayed states are the resut of the state information anaysis, defined by the user in the ogic modue. A fashing menu symbo signas the occurrence of an aarm The status dispay of the LED's is performed ony, if the associated ogic functions have been configured accordingy Aarm text indication on the dispay The dispayabe aarm ist is the resut of the state information anaysis, defined by the user in the ogic modue. The number of entries in the aarm ist depends on how many ogic functions are used. If no function is used, no aarm ist can be dispayed. If ogic functions are defined, the aarm ist may contain up to four entries, each with the states of the ogic function and the possiby assigned foow-up action (reay or digita output). To each aarm a state text for the active and the inactive state can be assigned. The aarm ist contains, depending on the present state, either the text for the active or the inactive aarm. Dispay aarm ist: foowed by Reset of aarms If aarm reset via dispay is configured each aarm occurred needs to be reset individuay to undo a possibe foow-up action (e.g. the switching of a reay). The subsequent sequence shows how to undo the foow-up action of an aarm: 1. Dispay aarm ist (see 7.4.2) 2. Seect entry using and 3. Seect 39/69 Device handbook APLUS with TFT dispay, , 04/2016

40 7.5 Resetting measurements The APLUS provides minimum and maximum vaues of different measured quantities as we as energy meters and operating hour counters. A of them may be reset during operation. 1. Seect menu 2. Seect sub-menu 3. Seect entry using and 4. Seect to reset entry Resetting of measurements may be protected via the security system impemented in the device. For further information see protection against device data changing. 7.6 Configuration A compete configuration of the APLUS is possibe via CB-Manager software ony using the configuration interface of the device. Via device ony the parameters described beow may be modified. To do so, a configuration menu is provided. 1. Seect menu 2. Seect sub-menu 3. Dispay the parameter to modify using the arrow keys 4. Seect 5. Perform the changing. Procedure depends on the quantity to modify: Vaue setting: Change by means of the arrow keys Seect a ist entry: Use and to seect the desired entry Seection: Use or for actiavting / deactivating the parameter 6. Use to acknowedge or to cance Setting time and date A time information stored in the device is referenced to UTC 1) (Universa Time Coordinated). For a better understanding the time/date information dispayed on the dispay can be converted to oca time by defining a time zone offset. This offset is added to the interna UTC time before the time information is dispayed. Keep in mind that the offset may be variabe if dayight saving time is used ocay (see beow). Hint: If time is set via CB-Manager software the difference between oca time and UTC rather resuts from the oca time settings of the PC than from the time zone offset configured via dispay. There may be a discrepancy. 1) UTC (Universa Time Coordinated) Sometimes UTC is caed word time as we. The reference corresponds to the Greenwich Mean Time (GMT). The time zones of the word nowadays are a referenced with an offset to UTC. UTC time doesn't use time shifts, which may occur due to a change to dayight saving time. Exampe: In Switzerand the CET (Centra European Time) is vaid, which has an offset of +1[h] to UTC. But during haf of the year the CEST (Centra European Summer Time) is used, which has an offset of +2[h] to the UTC time used in the device. 40/69 Device handbook APLUS with TFT dispay, , 04/2016

41 7.7 Data ogger The data ogger offers a periodica acquisition of measurement data, such as recording oad profies, measurement fuctuations or meter readings as we as event triggered recordings of aarm states or distubances. This storage medium used is an SD card, which aows amost unimited recordings and an easy exchanging on-site.

If it was active it remains active, if it was inactive it remains inactive. The activation / deactivation of a specific ogger may be performed via PC software or via the oca programming menu. Ony via PC software, respectivey by using the corresponding commands via the configuration interface, contents of the individua ogger can be reset. Lists are exceptiona, because they are aways active to prevent manipuations. They record events in endess mode and can t be reset SD card The device is suppied with a 2 GByte SD card, which aows ong-term recodings. The device can be equipped with a other SD cards avaiabe. The red LED of the key ocated next to the SD card signaizes that the ogger is active. During writing to the card the LED becomes dark for a short time. To exchange an SD card the key must be pressed. As soon as the red LED becomes dark, the SD card can be removed and the new card inserted. Data can t be atched in the device. Therefore there is no recording for the time no card is present in the device. The state of the SD card is shown in the ogger state dispay.

If there are no harmonics present in the system, it corresponds to the cosφ (see aso Reactive power). The PF has a range of , where the sign gives the direction of energy fow. The oad factor LF is a quantity derived from the PF, which aows making a statement about the oad type. Ony this way it's possibe to measure a range ike 0.5 capacitive inductive in a non-ambiguous way. The reactive power factor QF gives the reation between reactive and apparent power. 52/69 Device handbook APLUS with TFT dispay, , 04/2016

53 Zero dispacement votage U NE Starting from the generating system with star point E (which is normay earthed), the star point (N) on oad side is shifted in case of unbaanced oad. The zero dispacement votage between E und N may be determined by a vectoria addition of the votage vectors of the three phases: U NE = - (U 1N + U 2N + U 3N ) / 3 A dispacement votage may aso occur due to harmonics of order 3, 9, 15, 21 etc., because the dedicated currents add in the neutra wire. Earth faut monitoring in IT systems Via the determination of the zero dispacement votage it's possibe to detect a first earth faut in an unearthed IT system. To do so, the device is configured for measurement in a 4-wire system with unbaanced oad and the neutra connector is connected to earth. In case of a singe phase earth faut there is a resuting zero dispacement votage of U LL/ 3. The aarming may be done e.g. by means of a reay output. Transformer, secondary side Load Because in case of a faut the votage triange formed by the three phases does not change the votage and current measurements as we as the system power vaues wi be sti measured and dispayed correcty. Aso the meters carry on to work as expected. The method is suited to detect a faut condition during norma operation. A decination of the isoation resistance may not be detected this way. This shoud be measured during a periodica contro of the system using a mobie system. Another possibiity to anayze faut conditions in a grid offers the method of the symmetrica components as described in A3. 53/69 Device handbook APLUS with TFT dispay, , 04/2016

They arise if non-inear oads, such as RPM reguated drives, rectifiers, thyristor controed systems or fuorescent amps are present in the power system. Thus undesired side effects occur, such as additiona thermica stress to operationa resources or eectrica mains, which ead to an advanced aging or even damage. Aso the reiabiity of sensitive oads can be affected and unexpainabe disturbances may occur. In industria networks the image of the harmonics gives good information about the kind of oads connected. See aso: Increase of reactive power due to harmonic currents TDD (Tota Demand Distortion) In the APLUS the compete harmonic content of the currents is shown as Tota Demand Distortion, briefy TDD. This vaue is scaed to the rated current resp. rated power. Ony this way it's possibe to estimate the infuence of the current harmonics on the connected equipment correcty. Maximum vaues The maximum vaues of the harmonic anaysis arise from the monitoring of THD and TDD. The maximum vaues of individua harmonics are not monitored separatey, but are stored if a maximum vaue of THD or TDD is detected. The image of the maximum harmonics therefore aways corresponds to the dedicated THD resp. TDD. The accuracy of the harmonic anaysis depends strongy on the quaity of the current and votage transformers possiby used. In the harmonics range transformers normay change both, the ampitude and the phase of the signas to measure. It's vaid: The higher the frequency of the harmonic, the higher its damping resp. phase shift. 54/69 Device handbook APLUS with TFT dispay, , 04/2016

Aso harmonics of the 3rd, 9th, 15th, 21st etc. order, which add in the neutra wire, may ead to imbaance. Operating resources dimensioned to rated vaues, such as three-phase generators, transformers or motors on oad side, may be excessivey stressed by imbaance. So a shorter ife cyce, a damage or faiure due to thermica stress can resut. Therefore monitoring imbaance heps to reduce the costs for maintenance and extends the undisturbed operating time of the used resources. Imbaance or unbaanced oad reays use different measurement principes. One of them is the approach of the symmetrica components, the other one cacuates the maximum deviation from the mean-vaue of the three phase vaues. The resuts of these methods are not equa and don't have the same intention. Both of these principes are impemented in the APLUS. Symmetrica components (acc. Fortescue) The imbaance cacuation method by means of the symmetrica components is ambitious and intensive to cacuate. The resuts may be used for disturbance anaysis and for protection purposes in three-phase systems. The rea existing system is divided in symmetrica system parts: A positive sequence, a negative sequence and (for systems with neutra conductor) a zero sequence system. The approach is easiest to understand for rotating machines. The positive sequence represents a positive rotating fied, the negative sequence a negative (braking) rotating fied with opposite sense of direction. Therefore the negative sequence prevents that the machine can generate the fu turning moment. For e.g. generators the maximum permissibe current imbaance is typicay imited to a vaue of %. Maximum deviation from the mean vaue The cacuation of the maximum deviation from the mean vaue of the phase currents resp. phase votages gives the information if a grid or substation is imbaanced oaded. The resuts are independent of rated vaues and the present oad situation. So a more symmetrica system can be aspired, e.g. by changing oads from one phase to another. Aso faiure detection is possibe. The capacitors used in compensation systems are wear parts, which fai quite often and then have to be repaced. When using three phase power capacitors a phases wi be compensated equay which eads to amost identica currents fowing through the capacitors, if the system oad is comparabe. By monitoring the current imbaance it's then possibe to estimate if a capacitor faiure is present. The maximum deviations are cacuated in the same steps as the instantaneous vaues and therefore are arranged there (see A1). 55/69 Device handbook APLUS with TFT dispay, , 04/2016

Reactive power arises by means of the inductive oad. But the number of non-inear oads, such as RPM reguated drives, rectifiers, thyristor controed systems or fuorescent amps, is increasing. They cause nonsinusoida AC currents, which may be represented as a sum of harmonics. Thus the reactive power to transmit increases and eads to higher transmission osses und higher energy costs. This part of the reactive power is caed distortion reactive power. Normay reactive power is unwanted, because there is no usabe active component in it. Because the transmission of reactive power over ong distances is uneconomic, it makes sense to insta compensation systems cose to the consumers. So transmission capacities may be used better and osses and votage drops by means of harmonic currents can be avoided.
