4 IMPORTANT WARNING DANGER The SM16D meter is designed to fit alongside or inside a distribution board. This involves high voltage electricity which is dangerous and can cause harm or even death. This unit must only be fitted by a qualified electrician. Disconnect supply before fitting. Read the instructions and use only as directed. For internal use only. Do not exceed maximum ratings.

5 OVERVIEW The 16 Channel Semi Fiscal Distribution Board Smart Meter is a power measuring meter with 16 inputs designed for general home, industrial and office use. It is designed to measure the power being used in the circuits of a distribution board so that you can see which circuits are consuming the most power. The unit measures the power going through the first channel, as detected by the current sensor that you attach to the unit and then wirelessly reports it to the Energy Manager software for reporting and analysis. It then switches to the second channel, measures and reports the power being used and the cycle repeats until all 16 channels have been analysed and reported. It then cycles around again. As each channel takes around 10 seconds to scan, this gives the time between successive power reports on a channel to be around 160 seconds. Individual channels can be disabled should you wish. The meter also reports the current in each channel it measures, the voltage, the apparent power and the phase angle. Notes 1- From the active power and apparent power readings reported by the SM16D, the reactive power can be calculated. Note 2 - The SM16D ignores any power used on any channel that is not currently being monitored. As such it is not suitable for use in billing applications. In these circumstances, a fiscal meter such as the BBSP-SUB3 should be used in place of the SM16D. OPTIONAL THREE PHASE MODE The SM16D takes its voltage measurements from Phase 1 live connection attached to connection 24. It does not connect to phases 2 or 3. Measuring the true power on circuits connected to these phases is, therefore, not normally possible. In the Energy Manager Online, however, the SM16D can be set to Three Phase mode to overcome these problems. In Three Phase Mode, the Energy Manager Online assumes that: 1. The voltage on Phases 2 and 3 is exactly the same as Phase 1 (which the SM16D measures) and 2. The phase angle / power factor on phases 2 and 3 is the same as phase 1 (which the SM16D also measures). The software then gives readings for power consumption based on these assumed voltages and power factor as well as the currents that it measures on each circuit. Page 5

6 Note that this facility is a software setting in Energy Manager Online and it does not effect the SM16D hardware in any way. COMPATIBLE CURRENT SENSORS Two different clamps can be fitted to the meter allowing current consumptions of up to 100A per circuit to be measured. The meter has been tuned to work with Enistic current sensors only. Connecting third party sensors to the meter not only may give you incorrect readings but may damage your meter and void your warranty. Current sensors are not included and are available separately. Sensors that are compatible with the semi fiscal meter are: Sensor part number Current measuring maximum per channel (A) BBSP-CT30B BBSP-CT30C 25 BBSP-CT Notes 1. Currents in the range of 25.01A -> 32.00A can be measured using the BBSP-CT30B and BBSP- CT30C clamps, but the accuracy is not guaranteed to be better than AC2.0 in this range. 2. Whilst the new style clamps BBSP-CT30B and BBSP-CT30C are compatible, the old style clamp BBSP-CT30 cannot be used with the semi fiscal channel meter. Page 6

7 CONFIGURING THE CHANNEL METER TO USE DIFFERENT CLAMP SIZES Out of the box, the semi fiscal meter comes pre-configured to use 30A clamps such as the BBSP- CT30B or BBSP-CT30C. To configure your channel meter to use other clamp sizes, there is no configuration that is performed on the SM16D, but you will need to configure the software you are using, normally either the Energy Manager Desktop or Energy Manager Online. To configure the clamp size using Energy Manager Desktop: 1. Ensure you are running Energy Manager Desktop, Professional Edition, version 5.2 or later 2. Go the Meters tab 3. Select the relevant meter 4. Left click on the meter name to select it 5. Right click on it to bring up the menu 6. Select Edit 7. Choose the relevant clamp size from the list shown. Page 7

8 To change the clamp size using the Energy Manager Online edition: 1. Log on to your account 2. Show the list of meters available by selecting Live View -> All 3. Click on the appropriate meter to display the detailed meter information 4. Select the Calibration tab 5. Select Yes when asked about whether your meter was shipped recently a. NB All SM16D meters were shipped after this date 6. Choose the appropriate clamp size from the list shown Page 8

9 FITTING EXTENSION CABLES TO YOUR SENSORS The sensors come fitted with a 3.5mm mono jack socket which connects to the SM16D board. If you find that the cable fitted to the sensor is too short you can use an audio grade extension cable to extend your sensor cable length. Notes: When purchasing your extension lead, please ensure you use a shielded cable and a reasonably high grade of cable as poor quality cables will interfere with the accuracy of the readings. The length of extension cable that can be used will vary depending on the quality of the lead used and the amount of interference that the cable will be subject to in your installation. As a rule of thumb, extensions should be kept to around 1.5 -> 2m maximum. CONNECTING CLAMPS TO YOUR METER Clamps are connected to the meter by plugging them into the jack sockets around the edge of the PCB inside the meter. The steps to do this are: 1. Disconnect the supply 2. Attach the clamp to the Smart Meter before connecting the clamp to the circuit being monitored 3. Connect the clamp as shown below. Page 9

10 4. Note that connections 1,5,9,15 and 19 have the screening wire of multiple clamps connected to them. Page 10

11 BBSP-SM16D 16 Channel Semi Fiscal Distribution Board Smart Meter CLAMP ORIENTATION Note that it is important that your sensor clamps are connected round the right way. If your sensors are connected round the WRONG way, then the unit will have a power reading of 0W. This is often a good indication of incorrect installation orientation.

16 UNDERSTANDING THE SM16D LCD DISPLAY After startup, the LCD can be in one of two modes as shown below NB The active power, apparent power and current assume a 30A clamp is fitted. If you use a 100A instead, these figures will read approximately 9.81 times to low. Page 16

17 EWAPI WIRELESS MODES When in wireless mode, the LCD shows the status of the wireless network on the bottom line of the LCD display. Message Meaning Net:OK The wireless network is working correctly Net:Scan Trying to find a Smart Energy Controller Net:Found A Smart Energy Controller has been found Net:Hand The meter is negotiating security information with the Smart Energy Controller Net:Fail The wireless network is not working correctly Net:Join The meter is currently negotiating with the controller to be allowed to join its network Net:Send (C471) The meter is trying to send a wireless message to the controller. The last four digits of the serial number are shown in brackets. Page 17

18 ENABLING / DISABLING CHANNELS To enable or disable channels on the Smart Meter, you must have the following: BBSP-SM16D Zone controller: Firmware version 5.0 or above If you wish to use the desktop software to enable / disable channels you will need Energy Manager Pro Version 4.8 or above. USING THE ENERGY MANAGER ONLINE To enable or disable channels on your meter using Energy Manager Online: Log in to your account Select Settings -> Sockets Use the checkbox on the left of the meter channel name to enable or disable the relevant channel. USING ENERGY MANAGER PRO Run Energy Manager Pro and right click on any of the channels of the device you wish to modify in the meters screen Page 18

19 Select the option Send Raw Message A dialogue appears asking what message you wish to send. Enter one of the following messages types: TO ENABLE A CHANNEL 7004[(channel -1)in hex]00 e.g. to enable channel 1 type e.g.2 To enable channel 5 type To enable channel 14 type 70040D00 NB Channels are from 1 to 16 Page 19

20 To disable a channel, repeat the above but with the command 7004[(channel -1)in hex]00 In place of the 71. command. e.g D00 LOADING THE ENTIRE CHANNEL MASK If you send a command starting with 7204 then the entire channel mask is loaded in 1 go depending on the next hex BYTE. For example, to enable channels 1,3,12 and 14 BINARY of BIT 13 + BIT 12 + BIT 2 + BIT 0 (NB Notice that channel 1 represents Bit 0) = 2^13 + 2^11 + 2^2 + 2^0 = Page 20

21 = Now reverse the bytes of this 16 bit number and append to the 7204 command, ie Ld Channel Mask --X-X X-X WHAT YOU SHOULD SEE ON THE DEBUG LCD Once the command is received on the SM16, you will see the following output: Clr Channel Mask XXXX----XXXX---- Where Line1 Is either enable the channel: Set Channel Mask Or disable the channel: Clr Channel Mask Or load the entire channel mask in 1 go: Ld Channel Mask Page 21

22 And Line 2 shows the channel number on the left and debug information on the right (ignore this) And Line 3 shows the Channel Mask Display (see below). THE CHANNEL MASK DISPLAY The SM16 shows the Channel Mask Display either during startup sequence or when a channel mask command is received. The format of the display is a row containing 16 characters. Each character represents whether a channel is enabled or disabled. The left most character is channel 16 and the right most channel is channel 1. If the display shows an X it is enabled. If it shows a - it is disabled. e.g. The following channel mask display shows that channels 1,3, 12 and 14 are enabled Ld Channel Mask --X-X X-X Page 22

27 TESTING YOUR SM16 In order to test the operation of your Pulse Counter, you can use one of two methods, depending whether or not you have access to a BBSP_DBGLCD Debug LCD Display. TESTING THE POWER AND NETWORK CONNECTION 1. Apply power with the cover removed so you can see the LEDs on the Pulse Counter. 2. The LCD should show configuration and build information before it starts to measure power. 3. If the LCD fails to display, it is in an error condition and you should consult your Enistic representative Page 27

28 FREQUENTLY ASKED QUESTIONS Why is there a minimum power reading? The SM16D measures power using a series of sensors. At very low power ratings, the sensor design means that the signal coming from the sensors is too small to be accurately measured. Typically, this level is 10% of the maximum current your clamp is designed to measure. At values under 5% of the rated maximum of your clamp, the SM16 will read 0W. This avoids reporting spurious readings back to the rest of the system. For example, a system with a CT30B running at 230VAC, 50Hz: o The CT30B clamp has a maximum reading of 230VAC x 32A = 7360W. o Therefore the minimum power that the system can measure in the stated accuracy band when using this clamp is 10% - 100% of 7360W or 736W > 7360W. o The minimum value the SM16 will read is 5% of 7360W = 368W Does the SM16 measure the voltage? Yes, the SM16D measures voltage and current. How accurate is the SM16? For everyday use, the rated accuracy for the SM16 is 2%, which is the same accuracy as most electricity meters in use in the UK. Do I get a penny perfect reading from the SM16? The accuracy of the SM16 is acceptable in most cases, typically under 2% but three other factors must be taken into consideration when assessing the overall accuracy of the readings coming from the SM16 including: o Clamp accuracy: Each clamp will have an inaccuracy measure, typically 1%, and this inaccuracy must be taken into consideration when assessing the overall accuracy of the readings produced. Can the SM16 be used for billing purposes? The SM16 can be used to apportion bills effectively between different circuits, but because of the meter does not record energy (only power) we do not recommend using the SM16 for absolute billing purposes. For these purposes, please consider getting one of the fiscal meter range of products. Can I mix clamp sizes on the SM16? Yes, for all units sold after 10 November 2010, different clamp sizes can be used. Software Page 28
