19 3 Product description 3 Product description The device serves to keep constant the output voltage of a transformer with an on-load tap-changer. To do this, the device compares the transformer's measured output voltage (V actual ) with a defined desired voltage (V desired ). The difference between V actual and V desired is the control deviation (dv). If the control deviation is greater than the specified bandwidth (B%), the device emits a switching pulse after a defined delay time T1. The switching pulse triggers an on-load tap-changer tap change which corrects the transformer's output voltage. The device parameters can be optimally adjusted to the line voltage behavior to achieve a balanced control response with a small number of tap-change operations of the on-load tap-changer. The following diagram (on page 19) shows an overview of voltage regulation. Figure 1 Overview of voltage regulation Maschinenfabrik Reinhausen /02 EN TAPCON 230 basic 19

20 3 Product description 3.1 Performance features The voltage regulator is responsible for controlling tapped transformers. Apart from control tasks, the voltage regulator provides additional functions such as: Integrated protective functions: Undervoltage and overcurrent blocking Overvoltage detection with high-speed return Line drop compensation Compensation for voltage fluctuations in the meshed grid (Z compensation) Digital inputs and outputs can be individually programmed on-site by the user Additional indicators using LEDs outside the display for freely selectable functions Display of all measured values such as voltage, current, active power, apparent power or reactive power, power factor (cos φ) Plug terminals make it easier to connect the cables Selection of 3 different desired values Operating modes The device can be operated in the following operating modes: AUTO/MANUAL In auto mode (AUTO), the voltage is automatically controlled in accordance with the set parameters. The settings cannot be changed in auto mode. In manual mode (MANUAL), no automatic control occurs. The motor-drive unit can be controlled via the device's operating panel. The settings can be changed. LOCAL/REMOTE In remote mode (REMOTE), commands from an external control interface are executed. In this case, manual operation of the,, and keys is disabled. 20 TAPCON 230 basic /02 EN Maschinenfabrik Reinhausen 2012

31 4 Packaging, transport and storage 4 Packaging, transport and storage 4.1 Packaging Purpose The packaging is designed to protect the packaged goods both during transport and for loading and unloading as well as during periods of storage in such a way that no (detrimental) changes occur. The packaging must protect the goods against permitted transport stresses such as vibration, knocks and moisture (rain, snow, condensation). The packaging also prevents undesired position changes of the packaged goods within the packaging during storage. The packaged goods must be prepared for shipment before actually being packed so that the goods can be transported safely, economically and in accordance with regulations Suitability, structure and production The goods are packaged in a sturdy cardboard box. This ensures that the shipment remains in the intended transport position and that none of its components touches the load surface during transport or the floor after it is unloaded. The box is designed for a maximum load of 10 kg. Inlays inside the box stabilize the goods, preventing impermissible changes of position, and protect them from vibration. Maschinenfabrik Reinhausen /02 EN TAPCON 230 basic 31

32 4 Packaging, transport and storage Markings The packaging bears a signature with symbols with instructions for safe transport and correct storage. The following symbols apply to the dispatch (of non-hazardous goods). Adherence to these symbols is mandatory. Protect against moisture Top Fragile Figure 8 Shipping pictograms 4.2 Transportation, receipt and handling of shipments In addition to oscillation and shock stress, jolts must also be expected during transportation. In order to prevent possible damage, avoid dropping, tipping, knocking over and colliding with the product. If a crate falls from a particular height (e.g. when slings tear) or experiences an unbroken fall, damage must be expected regardless of the weight. Before acceptance, all deliveries must be checked by the recipient (acknowledgement of receipt) for the following: Completeness based on the delivery slip External damage of any type. The checks must take place after unloading when the crate can be accessed from all sides. If external transport damage is detected on receipt of the shipment, proceed as follows: Immediately record the transport damage found in the shipping documents and have this countersigned by the carrier. In the event of severe damage, total loss or high damage costs, immediately notify the sales department at Maschinenfabrik Reinhausen and the relevant insurance company. 32 TAPCON 230 basic /02 EN Maschinenfabrik Reinhausen 2012

33 4 Packaging, transport and storage After identifying the damage do not modify the condition of the shipment further and also retain the packaging material, until an inspection decision has been made by the transport company or the insurance company. Record the details of the damage immediately together with the carrier involved. This is essential for any claim for damages! If possible, photograph damage to packaging and packaged goods. This also applies to signs of corrosion on the packaged goods due to moisture inside the packaging (rain, snow, condensation). Name the damaged parts. When damages are hidden, i.e. damages which are not determined until unpacking after the receipt of the shipment, proceed as follows: Make the party responsible for the damage liable as soon as possible by telephone and in writing, and prepare a damage report. Observe, in this regard, the time periods applicable to such actions in the respective country. Inquire about these in good time. With hidden damage, it is very hard to make the transportation company (or other responsible party) liable. Any insurance claims for such damages can only be successful if relevant provisions are expressly included in the insurance terms and conditions. 4.3 Storage of shipments Selection and arrangement of the storage location should meet the following requirements: Stored goods are protected against moisture (flooding, water from melting snow and ice), dirt, pests such as rats, mice, termites and so on, and against unauthorized access. Store the box on timber beams and planks as a protection against rising damp and for better ventilation. Carrying capacity of the ground under the goods is sufficient. Entrance and exit paths are kept free. Check stored goods at regular intervals. Also take appropriate action after storms, heavy rain or snow and so on.

WARNING Electric shock Connection mistakes may endanger life Earth the voltage regulator using the grounding screw on the housing. Pay attention to the phase difference of the secondary terminals for the current and voltage transformers. Connect the output relays correctly to the motor-drive unit. NOTICE Damage to device and system periphery An incorrectly connected device can lead to damages in the device and system periphery. Prior to commissioning, be sure to check the entire configuration and the actual and operating voltage. To obtain a better overview when connecting cables, only use as many leads as necessary. Use only the specified cables for wiring. You will find a cable recommendation in the corresponding section (see "Cable recommendation" on page 48). When wiring, proceed as described in the Wiring (see "Wiring the device" on page 55) section. 54 TAPCON 230 basic /02 EN Maschinenfabrik Reinhausen 2012

55 5 Mounting Supplying the voltage regulator using an auxiliary voltage The device is normally supplied by the voltage transformer. If the voltage transformer does not provide the supply voltage and power (see "Technical Data" on page 161) needed for operation, the device must be supplied via a V AC/DC, Hz auxiliary supply. NOTICE Voltage transformer damage Connecting an auxiliary voltage when bridges are present between the X2:1/3 and X2:2/4 terminals can result in voltage transformer damage. Remove the bridges between the X2:1/3 and X2:2/4 terminals if supplying the device with an auxiliary voltage. Proceed as follows to supply the device with auxiliary voltage: 1. Remove the bridges between terminals X2:1/3 and X2:2/4. 2. Connect the voltage transformer to terminals X2:1 and X2:2. 3. Connect the auxiliary voltage to terminals X2:3 and X2:4.

59 5 Mounting 5.5 Function check Carry out a function check to test that the voltage regulator is wired correctly. Check the following: After being switched on, the screen displays the MR logo and then a voltage value. The green "Operating display" LED in the top left on the voltage regulator lights up. The voltage regulator can now be configured. The actions required for this are described in the following chapter (see "Commissioning" on page 61).

61 6 Commissioning 6 Commissioning Several parameters need to be set and function tests performed before commissioning the device. These are described in the following chapter. 6.1 Commissioning NOTICE Damage to device and system periphery An incorrectly connected device can lead to damages in the device and system periphery. Prior to commissioning, be sure to check the entire configuration and the actual and operating voltage. We recommend using a registration device to record the transformer voltage (actual value) in order to evaluate how the voltage regulator is functioning. Maschinenfabrik Reinhausen /02 EN TAPCON 230 basic 61

62 6 Commissioning 6.2 Configuration The relevant settings for commissioning are described in more detail in the following sections Setting the language You can change the display language. The following languages are available: English German French Spanish Italian Portuguese Russian 1. > Configuration > General. <00> Language. 2. Press or to select the required language. 3. Press. The language is set. 62 TAPCON 230 basic /02 EN Maschinenfabrik Reinhausen 2012

63 6 Commissioning Selecting control mode You can commission the device with limited parameterization (NORMset) or complete parameterization. Instead of complete parameterization, the NORMset mode enables easy and user-friendly commissioning with a limited set of parameters. If you select this mode, you have to set the desired voltage. All other voltage regulation parameters are determined automatically. The relevant transformer should be loaded with around 50 % to 80 % of the nominal transformer power. Proceed as follows to start up the device in NORMset mode: 1. Press to select manual mode. 2. Activate NORMset mode. 3. Set desired value 1. The value is set in V (secondary voltage) by default. You can also set "desired value 1" in kv (primary voltage). To do so, you must change the display from V to kv (page 120). This setting also determines whether the actual value is displayed in V or kv. 4. Set the primary voltage. 5. Set the secondary voltage. 6. Execute one tap-change operation manually. A manual tap-change operation is required once NORMset has been activated. This is how the voltage regulator determines the bandwidth required. If the transformer has been switched off, another manual tap-change operation is required. When these parameters have been set, the device is ready to operate. Now continue with the Function tests (page 64). The compensation settings cannot be carried out in NORMset mode. The desired value will be compared with the measured voltage (V actual ) on the device. Maschinenfabrik Reinhausen /02 EN TAPCON 230 basic 63

64 6 Commissioning 6.3 Function tests Before switching from manual mode to automatic mode and therefore activating the automatic voltage regulation for your system, Maschinenfabrik Reinhausen recommends carrying out function tests. These function tests are described in the following sections Function tests for control functions REMOTE mode must be disabled before you can control the on-load tapchanger manually in manual mode. The on-load tap-changer can only be controlled in manual mode using the or keys. 1. Press to select manual mode. 2. Measure actual voltage and compare with that displayed by the device. 3. Press several times to display the operating values for current, output and phase angle. If necessary, measure and compare operating values with operating measurement devices at the same time. 4. Control the on-load tap-changer manually with the or keys until the measured voltage (V Act ) reaches the desired voltage (V Des ) set in the next step. 5. Set desired value 1 to the value of V Des. 6. Set bandwidth "B %" depending on step voltage. [±B % ] 0.6 U n-1 U n U nominal 100 % 7. Set delay time T1 to 20 s. 8. Set control response T1 to "T1 linear". 9. Press to raise the on-load tap-changer 1 step. 10. Press to select auto mode. 64 TAPCON 230 basic /02 EN Maschinenfabrik Reinhausen 2012

65 6 Commissioning After 20 s, the device returns the on-load tap-changer to the original operating position. 11. Press to select manual mode. 12. Press to lower the on-load tap-changer 1 step. 13. Press to select auto mode. After 20 s, the device returns the on-load tap-changer to the original operating position. 14. Press to select manual mode. 15. Activating delay time T2 16. Set delay time T2 to 10 s. 17. Press twice to raise the on-load tap-changer 2 steps. 18. Press to select auto mode. After 20 s, the device lowers the on-load tap-changer one step and after another 10 seconds another step. 19. Press to select manual mode. 20. Set delay times T1 and T2 to the desired values. If T2 is not used, select the "OFF" value. We recommend a temporary setting of 100 seconds for the delay time T1 when commissioning the transformer. Depending on the operating conditions, you can also specify the delay time following a longer observation period. In this regard, it is useful to register the actual voltage's progress and the number of tap-change operations per day. 21. To define an integral time response for the voltage regulator, set the control response T1 to the value "T1 integral". The greater the control deviation, the shorter the delay time. Maschinenfabrik Reinhausen /02 EN TAPCON 230 basic 65

66 6 Commissioning Function tests for additional functions REMOTE mode must be disabled before you can control the on-load tapchanger manually in manual mode. The on-load tap-changer can only be controlled in manual mode using the or keys. Setting V< undervoltage limit and checking undervoltage blocking Undervoltage blocking is activated as standard. 1. Press to select manual mode. 2. Set V< undervoltage limit to 85 %. 3. Set desired value 1 such that the measured voltage (V Act ) is below the V< undervoltage limit Example: Measured voltage = 100 V, set desired value 1 to 120 V (greater than 100 V/0.85 = 117 V). The red V< undervoltage LED will light up. After around 10 s the "Undervoltage" message appears in the display and the relevant signaling relay is activated. Contact X4:1/3 closes and contact X4:2/3 opens. 4. Press to select auto mode. The device is blocked and does not therefore issue any control commands. 5. Press to select manual mode. 6. Set the operating values you want for desired value 1 and V< undervoltage limit. 66 TAPCON 230 basic /02 EN Maschinenfabrik Reinhausen 2012

67 6 Commissioning Setting V> overvoltage limit and checking overvoltage blocking Overvoltage blocking is activated as standard. 1. Press to select manual mode. 2. Set V> overvoltage detection to 115 %. 3. Set desired value 1 such that the measured voltage (V Act ) is above the V> overvoltage limit. Example: Actual voltage = 100V, set desired value 1 to 85 V (less than 100V/1.15 = 87V). The red V> overvoltage LED will light up. The "Overvoltage" message appears in the display and the relevant signaling relay is activated. Contact X4:1/3 closes and contact X4:2/3 opens. 4. Press to select auto mode. The LOWER output relay periodically emits a control command at approx. 1.5 s intervals. 5. Press to select manual mode. 6. Set the operating values you want for desired value 1 and V> overvoltage limit. Setting overcurrent limit I> and undercurrent limit I< Setting the undercurrent limit is optional. The factory setting is 0 %. Over- and undercurrent blocking are activated by default. Set overcurrent limit I> and, optionally, undercurrent limit I< to the desired value. A function test is not necessary. Maschinenfabrik Reinhausen /02 EN TAPCON 230 basic 67

Checking and setting line drop compensation (LDC) A load current of 10 % of the nominal transformer current is needed for the following function tests. 1. Press to select manual mode. 2. Set parameters for line drop compensation and Z compensation to Select the control deviation (dv) display on the main screen (press if necessary). The measured voltage must be within the bandwidth. 4. Set line drop compensation Vr to 20.0 V. The control deviation dv must be negative. 5. Set line drop compensation Vr to V. The control deviation dv must be positive. If the control deviation appears in the opposite direction, change the polarity of the current transformer. 6. Set line drop compensation Vr to the operating value you want. 68 TAPCON 230 basic /02 EN Maschinenfabrik Reinhausen 2012

69 6 Commissioning Checking and setting Z compensation 1. Press to select manual mode. 2. Set parameters for line drop compensation and Z compensation to Select the control deviation (dv) display on the main screen (press if necessary).

71 7 Functions and settings 7 Functions and settings This chapter describes all the functions and setting options for the device. The setting values appear in the relevant sections and in summary in the form of a table (page 150). The chapters are laid out following the menu structure of the device. The menu structure has the following structure: Main menu Press to select the main menu. Normset Control parameters Configuration Info Sub-menus Sub-menus are subordinated menu items. Example: Sub-menu Control parameters Voltage regulation Limit values Compensation To navigate through the menu structure press one of the function keys.... Parameter screen The parameter screens are located at the end of the menu paths. The parameter screens allow you to set values and functions. In a menu item you find several parameter screens. For example in the menu item Normset you find the following parameter screens: Normset activation Desired value 1 Primary voltage (optional) Secondary voltage Maschinenfabrik Reinhausen /02 EN TAPCON 230 basic 71

72 7 Functions and settings Press to navigate to the next parameter screen. Press to navigate to the previous parameter screen. The parameter screens are arranged in a continuous loop. Press navigate from the last to the first parameter screen rapidly. to Press or to change functions or values. The device functions are set using the keys on the device. Settings can only be carried out in manual mode (MANUAL). The key lock must be deactivated. The procedure for activating or deactivating the key lock is described in the following sections. 7.1 Key lock The device is equipped with a key lock to protect against unintentional operation. Parameters can only be carried out in manual mode (MANUAL) with a deactivated key lock Activating key lock To activate the key lock, proceed as follows: Press and at the same time. A confirmation (see diagram) appears on screen for a short period. The key lock is activated. Parameters can no longer be entered. 72 TAPCON 230 basic /02 EN Maschinenfabrik Reinhausen 2012

73 7 Functions and settings Deactivating key lock To deactivate the key lock, proceed as follows: Press and at the same time. The key lock is deactivated. Parameters can be entered. 7.2 NORMset As an alternative to parameterizing the voltage regulator manually, the NORMset mode enables easy commissioning of the voltage regulator with a limited set of parameters. When this mode is selected, the factory settings required for voltage regulation are adopted. When commissioning the voltage regulator in NORMset mode, the following parameters must be set: Desired value 1 Primary voltage Secondary voltage When these 3 parameters have been set, the voltage regulator is ready to operate. Once NORMset has been activated, no additional settings can be undertaken for line drop compensation. The desired value is compared with the measured voltage present on the voltage regulator depending on the unit defined, i.e. V (secondary voltage of voltage transformer) or kv (primary voltage of voltage transformer). If additional information on current and phase angle are required, connect the current transformer and adjust the current connection data (see "Setting the current transformer connection" on page 116). Maschinenfabrik Reinhausen /02 EN TAPCON 230 basic 73

74 7 Functions and settings After the desired voltage level and voltage transformer data have been entered, if NORMset is activated the voltage regulator checks the grid conditions and automatically adapts other settings, composed partly of predefined parameters and default values. All other parameters required for simple voltage regulation are predefined in the factory. The procedure for activating or deactivating NORMset mode is described in the following sections. A manual tap-change operation is required once NORMset has been activated. This is how the voltage regulator determines the bandwidth required. If the transformer has been switched off, another manual tap-change operation is required. If NORMset is activated, the bandwidth and delay time settings will be undertaken automatically by the voltage regulator. The following control parameters must be set in NORMset mode: Desired value 1 Primary voltage Secondary voltage The following parameters are not set automatically using the NORMset mode: Undervoltage limit Overvoltage limit Undercurrent limit Overcurrent limit If required, these parameters must be set manually. 74 TAPCON 230 basic /02 EN Maschinenfabrik Reinhausen 2012

Desired value 1, 2 and 3 Bandwidth Delay time T1 Control response T1 Delay time T Desired voltage values One important fixed value is the desired voltage level V Des. You can enter the desired value via the user interface in both the NORMset and the corresponding parameter screen of the voltage regulation sub-menu. During operation, you can change the level of a desired value and change between different desired values. You use the GPI5 and GPI6 binary inputs to define whether desired value 1, 2 or 3 is active. The default desired value is desired value 1.Desired values 2 or 3 are activated if there is a continuous signal at the pre-assigned GPIs 5 or 6 (factory preset). If there is a signal at both inputs at the same time, desired value 2 is active. The following sections describe how to set the desired values. Maschinenfabrik Reinhausen /02 EN TAPCON 230 basic 79

80 7 Functions and settings Setting desired values Desired values are set in V as standard and apply to the secondary voltage of the voltage transformer.

The selected desired value is active. Maschinenfabrik Reinhausen /02 EN TAPCON 230 basic 83

84 7 Functions and settings Bandwidth The bandwidth is the permitted deviation of the measured voltage (V Actual ) from the selected desired value. If the measured voltage is inside the bandwidth, then no control commands are issued to the on-load tap-changer. If the measured voltage deviates from the specified bandwidth, a tap-change command occurs after the set delay time T1. The on-load tap-changer carries out a tap-change in a positive or negative direction. If the level is persistently above or below the bandwidth, the Function monitoring alarm message is triggered after 15 minutes. The corresponding relay is also activated. The alarm message is only reset when the measured voltage returns to the set bandwidth. Figure 27 Measured voltage over time 1 ΔV Step : Step voltage 2 V Desired : Desired value in V 3 B%: Bandwidth range 4 T1: Set delay time 5 V Actual : Measured voltage a V Actual outside the bandwidth, T1 starts b V Actual within bandwidth before T1 lapses, no tap-change operation c V Actual outside the bandwidth, T1 starts d V Actual outside B% before T1 lapses, tap-change operation initiated e Tap-change operation complete, V Actual within the bandwidth 84 TAPCON 230 basic /02 EN Maschinenfabrik Reinhausen 2012

85 7 Functions and settings Visual display The deviation from the set bandwidth is shown visually in the device display. The measured voltage mark (V actual ) shows whether the measured voltage is above, within or below the set bandwidth. Progress of delay time T1 is indicated by the gradual filling of the time bar in the device display. The seconds display above this indicates the remaining delay time T1. Figure 28 Visual display of deviation from desired value 1 Bandwidth (upper and lower limit) 2 Time bar for delay time T1 3 Desired voltage value 4 Measured voltage (V actual ) 5 Remaining delay time T1 Maschinenfabrik Reinhausen /02 EN TAPCON 230 basic 85

86 7 Functions and settings Determining bandwidth In order to be able to set the value correctly, the transformer's step voltage and nominal voltage must be known. The following value is recommended for the bandwidth "B %": [±B % ] 0.6 U n-1 U n U nominal 100 % V n-1 Step voltage of position n-1 V n Step voltage of position n V Nominal Nominal voltage The bandwidth must be selected in such a way that the output voltage of the transformer (V actual ) returns to within the specified tolerance range after the tap change. If too small a bandwidth is defined, the output voltage exceeds the bandwidth selected and the device must immediately issue a tap-change command in the opposite direction. If a very large bandwidth is selected, this results in a major control deviation. Sample calculation The following transformer parameters are used by way of example for determining the recommended bandwidth: Nominal voltage: Step voltage of position 4: Step voltage of position 5: V Nominal = V V Step4 = V V Step5 = V 86 TAPCON 230 basic /02 EN Maschinenfabrik Reinhausen 2012

87 7 Functions and settings Following the recommendation for calculating bandwidth, our example results in: [±B % ] 0.6 V Step4 V Step5 V Nominal 100 % [±B % ] V V V 100 % [±B % ] 1.5 % Setting the bandwidth Setting range Step size Factory setting 0.5 % to 9 % 0.01 % 2 % Table 18 Setting range for bandwidth The calculated bandwidth is entered as follows: 1. > Control Parameters > Voltage Regulation > 4x. <04> Bandwidth. 2. Press to highlight a digit. The digit position you want is highlighted and the value can be changed. 3. Press to increase the value or to reduce it. 4. Press. The bandwidth is set. Maschinenfabrik Reinhausen /02 EN TAPCON 230 basic 87

88 7 Functions and settings Setting delay time T1 Delay time T1 delays the issuing of a tap-change command for a defined period. This function prevents unnecessary tap-change operations if the tolerance bandwidth is exited. If the current measured voltage exits the bandwidth, delay time T1 starts. This is shown in the display by the time bar filling and the remaining time being indicated. If the control deviation is still present after the delay time, a tap-change command is issued. If during the delay time the measured voltage returns to within the bandwidth range, the delay time still running is counted down in seconds starting from the time already expired. The absolute time display disappears from the display. The time bar is shown hatched and shrinks steadily. If the measured voltage exceeds the set bandwidth once more whilst the time is not displayed, then the time delay is restarted from the remaining time. The benefit of this method is that the effective time delay is reduced if the bandwidth is frequently exceeded. The device responds faster because the time measurement for the delay time doesn't start at 0 seconds but, for example, at 5 seconds. 88 TAPCON 230 basic /02 EN Maschinenfabrik Reinhausen 2012

89 7 Functions and settings Setting range Step size Factory setting 0 s to 600 s 1 s 40 s Table 19 Setting range for delay time T1 To set the delay time T1, proceed as follows: 1. > Control Parameters > Voltage Regulation > 5x. <05> Delay Time T1. 2. Press to highlight a digit. The digit position you want is highlighted and the value can be changed. 3. Press to increase the time or to reduce it. 4. Press. The delay time is set. Maschinenfabrik Reinhausen /02 EN TAPCON 230 basic 89

90 7 Functions and settings Setting control response T1 The control response T1 can be set to linear or integral. Both kinds of control response are explained below. Linear control response T1 The device responds with a constant delay time which is independent of the control deviation. Integral control response T1 The device responds with a variable delay time which is dependent on the control deviation. The greater the control deviation (ΔV) in relation to the set bandwidth (B), the shorter the delay time. The delay time can therefore be reduced down to 1 second. This means that the device reacts faster to large voltage changes in the grid. The level of regulation accuracy increases. Switching frequency however also increases (see diagram).

132 7 Functions and settings Monitoring motor runtime The motor-drive unit's runtime can also be monitored by the voltage regulator. This function is used to identify motor-drive unit malfunctions during the tapchange operation and to trigger any actions needed. The corresponding control input must be correctly wired and parameterized to "Motor running" in order to use runtime monitoring. The motor runtime must also be set. The motor-drive unit supplies the "Motor running" signal during the tapchange operation. This signal is present until the tap-change operation is complete. The voltage regulator compares the duration of this signal with the motor runtime set. If the set motor runtime is exceeded, the voltage regulator triggers various actions: 1. "Motor runtime monitoring" message 2. Continuous signal via output relay "Motor-drive unit runtime exceeded" (optional) 3. Impulse signal via output relay "Trigger motor protective switch" (optional) 132 TAPCON 230 basic /02 EN Maschinenfabrik Reinhausen 2012

133 7 Functions and settings Wiring and parameterizing control input/output relay If you want to monitor the motor runtime, the voltage regulator and motordrive unit must be connected and parameterized as shown below. Figure 40 Wiring for motor runtime monitoring 1 GPI "Motor running" 2 GPI "Motor protective switch tripped" (optional) 3 GPO "Motor protective switch tripped" (optional) 4 GPO "Motor runtime exceeded" (optional) In order to be able to use the GPOs, you must wire the feedback from the motor-drive unit "Motor protective switch tripped" to a GPI and parameterize the GPI (see "Assigning function to inputs (GPIs)" on page 135). This message resets the "Motor runtime exceeded" GPO when the motor protective switch is switched back on and activates the "Motor protective switch tripped" message.
