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 (Vactual) with a defined desired voltage (Vdesired). The difference between Vactual and Vdesired is the control deviation (dV).

If the control deviation is greater than the specified bandwidth (B%), the de-vice emits a switching pulse after a defined delay time T1. The switching pulse triggers an on-load tap-changer tap change which corrects the trans-former'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



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

3.4.1 Operating concept

The voltage regulator's operating panel is split into an operation control level and a level for parameterization and configuration.

The keys for operating the device are completely separate from those used for parameterization. At the operation control level, key activation is signaled visually by means of LEDs.

The LEDs integrated in the and key are illuminated during the en-tire tap change operation of the on-load tap-changer if "motor running" is sig-naled at the status input. This signal must have previously been parameterized.

This visual monitoring option makes operation of the device easier.

4 Packaging, transport and storage



4.1 Packaging

4.1.1 Purpose

The packaging is designed to protect the packaged goods both during trans-port 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.

4.1.2 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 com-ponents touches the load surface during transport or the floor after it is un-loaded.

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.



4.1.3 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 (acknowl-edgement 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, imme-diately notify the sales department at Maschinenfabrik Reinhausen and the relevant insurance company.



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 in-volved. 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 un-packing 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 insur-ance 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.

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 vol-tage 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).

6 Commissioning


6 Commissioning

Several parameters need to be set and function tests performed before com-missioning 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.

6 Commissioning


6.2 Configuration

The relevant settings for commissioning are described in more detail in the following sections.

6.2.1 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 lan-

guage.

3. Press .

The language is set.

6 Commissioning


6.2.2 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 para-meters 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 "de-sired value 1" in kV (primary voltage). To do so, you must change the dis-play 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 acti-vated. This is how the voltage regulator determines the bandwidth required. If the transformer has been switched off, another manual tap-change opera-tion 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 de-sired value will be compared with the measured voltage (Vactual) on the device.

6 Commissioning


6.3 Function tests

Before switching from manual mode to automatic mode and therefore activat-ing the automatic voltage regulation for your system, Maschinenfabrik Rein-hausen recommends carrying out function tests. These function tests are described in the following sections.

6.3.1 Function tests for control functions

REMOTE mode must be disabled before you can control the on-load tap-changer manually in manual mode.

The on-load tap-changer can only be controlled in manual mode using the

or keys.


2. Measure actual voltage and compare with that displayed by the device.

3. Press several times to display the operating values for current, out-put and phase angle. If necessary, measure and compare operating val-ues with operating measurement devices at the same time.

4. Control the on-load tap-changer manually with the or keys until the measured voltage (VAct) reaches the desired voltage (VDes) set in the next step.

5. Set desired value 1 to the value of VDes.

6. Set bandwidth "B %" depending on step voltage.

[±B % ] 0.6 Un-1 Un

100 %

Unominal

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.

6 Commissioning


After 20 s, the device returns the on-load tap-changer to the original operating position.


12. Press to lower the on-load tap-changer 1 step.


After 20 s, the device returns the on-load tap-changer to the original operating position.


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.


After 20 s, the device lowers the on-load tap-changer one step and af-ter another 10 seconds another step.


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 condi-tions, 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 con-trol response T1 to the value "T1 integral". The greater the control devia-tion, the shorter the delay time.

6 Commissioning


6.3.2 Function tests for additional functions

REMOTE mode must be disabled before you can control the on-load tap-changer 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.


2. Set V< undervoltage limit to 85 %.

3. Set desired value 1 such that the measured voltage (VAct) 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.


The device is blocked and does not therefore issue any control com-mands.


6. Set the operating values you want for desired value 1 and V< undervoltage limit.

Overvoltage blocking is activated as standard.


2. Set V> overvoltage detection to 115 %.

3. Set desired value 1 such that the measured voltage (VAct) 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.


The LOWER output relay periodically emits a control command at ap-prox. 1.5 s intervals.


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.

The parameter screens are arranged in a continuous loop. Press to navigate from the last to the first parameter screen rapidly.

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 opera-tion. Parameters can only be carried out in manual mode (MANUAL) with a deactivated key lock.

7.1.1 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. Pa-rameters can no longer be entered.



7.1.2 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 re-quired 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 op-erate.

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 vol-tage regulator depending on the unit defined, i.e. V (secondary voltage of vol-tage 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 cur-rent transformer connection" on page 116).



After the desired voltage level and voltage transformer data have been en-tered, if NORMset is activated the voltage regulator checks the grid conditions and automatically adapts other settings, composed partly of predefined para-meters 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 acti-vated. This is how the voltage regulator determines the bandwidth required. If the transformer has been switched off, another manual tap-change opera-tion is required.

If NORMset is activated, the bandwidth and delay time settings will be un-dertaken 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.

7.3.2 Desired voltage values

One important fixed value is the desired voltage level VDes. You can enter the desired value via the user interface in both the NORMset and the correspond-ing parameter screen of the voltage regulation sub-menu.

During operation, you can change the level of a desired value and change be-tween 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 acti-vated 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.



7.3.3 Setting desired values

Desired values are set in V as standard and apply to the secondary voltage of the voltage transformer. You can also set the desired value in relation to the voltage transformer's primary voltage in kV. Setting in kV requires all voltage transformer data (see "Transformer data" on page 111) to be input.

7.3.7 Bandwidth

The bandwidth is the permitted deviation of the measured voltage (VActual) 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 monitor-ing 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.

7.3.7.1 Visual display

The deviation from the set bandwidth is shown visually in the device display. The measured voltage mark (Vactual) shows whether the measured voltage is above, within or below the set bandwidth. Progress of delay time T1 is indi-cated by the gradual filling of the time bar in the device display. The seconds display above this indicates the remaining delay time T1.

7.3.7.2 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 Un-1 Un

100 %

Unominal

Vn-1 Step voltage of position n-1

Vn Step voltage of position n

VNominal Nominal voltage

The bandwidth must be selected in such a way that the output voltage of the transformer (Vactual) returns to within the specified tolerance range after the tap change. If too small a bandwidth is defined, the output voltage exceeds the band-width selected and the device must immediately issue a tap-change com-mand in the opposite direction. If a very large bandwidth is selected, this results in a major control devia-tion.

Sample calculation

The following transformer parameters are used by way of example for deter-mining the recommended bandwidth:

Nominal voltage: VNominal = 11000 V

Step voltage of position 4: VStep4 = 11275 V

Step voltage of position 5: VStep5 = 11000 V



Following the recommendation for calculating bandwidth, our example results in:

reduce it.

4. Press .

The bandwidth is set.



7.3.8 Setting delay time T1

Delay time T1 delays the issuing of a tap-change command for a defined pe-riod. This function prevents unnecessary tap-change operations if the toler-ance 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 in-dicated.

If the control deviation is still present after the delay time, a tap-change com-mand 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 dis-play. The time bar is shown hatched and shrinks steadily. If the measured vol-tage 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 exam-ple, at 5 seconds.

3. Press to increase the time or to re-

4. Press .

The delay time is set.



7.3.9 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).

3. Press .

The control response T1 is set.

7.3.10 Activating/deactivating delay time T2

The delay time T2 only takes effect if more than one tap-change operation is required for returning the voltage to within the specified bandwidth.With integral control response in particular, the time until release of an output pulse would increase after each tap change process.

The first output pulse occurs after the set delay time T1. After the set delay time T2 has elapsed, additional pulses occur. These are needed to correct the existing control deviation.

To activate/deactivate the delay time T2, proceed as follows:

7.3.12 Limit values

This sub-menu contains all the parameters required for monitoring the limit values. The limit values are set as percentage values.

For the undervoltage and overvoltage parameters, the inputs basically relate to the specified desired value. For the overcurrent and undercurrent parame-ters, the values relate to the set rated current of current transformer or the se-lected current transformer connection respectively.



7.3.12.1 Setting the undervoltage V< limit value

Undervoltage blocking prevents tap change operations of the tap changer if there is a power cut. The voltage regulator output pulses are blocked and the red "V<" LED lights up as soon as the measured voltage (Vactual) falls below the set limit value.

If the measured voltage (VAct) falls below the set limit value, the relevant sig-naling relay comes into operation after the set signaling delay time (page 94). Contact X4:1/3 closes and contact X4:2/3 opens.

7.3.12.3 Activating/deactivating V< undervoltage blocking

The undervoltage blocking can be activated or deactivated. When blocking is deactivated and the voltage falls below the V< undervoltage limit value, the red "V<" LED lights up. Contact X4:1/3 closes and contact X4:2/3 opens.However, the control is not blocked.

7.3.12.4 Activating/deactivating signal for V< undervoltage below 30 V

Disabling the "V< undervoltage" signal may be a good idea if you want to avoid error messages when the transformers are switched off (measured vol-tage (VAct) V< 30 V).

To disable the "V< undervoltage" signal, proceed as follows:

1. > Parameter > Limit values >

<03> V< Below 30 V.

2. Press or to activate (On)/deactivate

(Off) the "V< undervoltage" signal.

3. Press .

The "V< undervoltage" signal is acti-vated/deactivated.



7.3.12.5 Setting V> overvoltage limit value

When the overvoltage monitoring responds, the on-load tap-changer is ac-tuated by periodical activation of the motor-drive unit until the measured vol-tage (VAct) is less than the set overvoltage limit value.

Rapid return control

This is controlled by the output relay for the "Lower" switching direction at the intervals dictated by the set switching pulse time. In this case, the set switch-ing delay is inactive. As long as there is overvoltage, the red "V>" LED is illu-minated and the relevant signaling relay is activated. Contact X4:1/3 closes and contact X4:2/3 opens.

You can set the interval and/or the switching pulse time for LOWER (see "Setting the switching pulse time" on page 126).

If the limit value for "Overvoltage V> (%)" is exceeded, either control can take place via the quick switch-back or, instead, the control can be blocked.

The V> overvoltage limit is entered as a percentage of the set desired value.

When regulator blocking is activated, the control is blocked if a negative active power flow is detected. However, this is only possible if the current transfor-mer connection is connected and correctly set. When regulator blocking is deactivated, then the sign of the active power does not affect the regulation.

7.3.13 Compensation

The quality of the energy supply depends not only on the voltage at the bus-bar of the supply transformer (measurement value V), but also the voltage di-rectly at the equipment.

In some cases the line impedance - of the cables or overhead lines - needs to be taken into account for voltage regulation. A significant (load-dependent) voltage drop can occur in these lines. This voltage drop is dependent on the following factors at the consumer:

Impedance (apparent resistance)

Cable

Electrical current

Phase angle φ

The device has two possible ways of balancing a load-related voltage drop between the transformer and the consumer:

Line drop compensation

Z compensation



Comparison between line drop compensation and Z compensation

Line drop compensation (vectorial compensation):

provides more precise compensation of line voltage drops

requires several parameters

requires full knowledge of the line data

Z compensation:

can be used with minor changes in the phase angle φ

is not dependent on phase angle φ

is simple to set

can also be used in meshed grids

Both methods are described in more detail in the following sections.

7.3.13.1 Line-drop compensation

Line drop compensation requires exact line data. Line voltage drops can be compensated very accurately using LDC.

To set the line drop compensation correctly, you have to calculate the ohmic and inductive voltage drop, in relation to the secondary side of the voltage transformer in V. The existing measuring circuit also has to be set correctly.

The setting values must first be calculated in order to enter the correct values for the ohmic and inductive voltage drops.

Sample calculation:

Vr Setting for ohmic line voltage drop in V

Vx Setting for inductive line voltage drop in V

IN Nominal current in A of selected current transformer connection on device: 1 A or 5 A

kCT Current transformer ratio

kVT Voltage transformer ratio

r Ohmic line resistance in Ω/km per phase

x Inductive line resistance in Ω/km per phase

L Length of line in km



Formula for calculating the ohmic voltage drop "Vr":

Formula for calculating the inductive voltage drop "Vx":

Calculation:

IN = 5 A, kCT = 500 A/5 A, kVT = 30000 V/100 V, r = x = 10 Ω/km, L = 10 km



If the active voltage drop "Vr" and reactive voltage drop "Vx" are set correctly, then the voltage at the line end remains constant irrespective of the load.

Figure 31 Line drop compensation

The settings for the compensation methods are described in more detail be-low.



7.3.13.2 Selecting the compensation method

Before setting a compensation, a compensation method must be selected. You can select between "LDC" for line drop compensation and "Z" for Z com-pensation.

7.3.13.5 Setting Z compensation

Z compensation can be used for example for minor changes to the phase an-gle φ. It can also be used for meshed grids. Z compensation is not however dependent on phase angle φ.

To correctly set the parameters, you need to calculate the voltage increase (ΔV) taking the current into account.

7.4.2.2 Setting the regulator ID

The serial number and firmware version are features of a voltage regulator. The regulator ID is only used as an additional unique feature for identifying the voltage regulator when communicating with the TAPCON®-trol software. The regulator ID consists of a sequence of digits (maximum 4 digits).

The regulator ID ensures that the link from the TAPCON®-trol software to a particular voltage regulator is established. During online communication, the TAPCON®-trol software installed on a PC establishes the regulator ID and compares this with those already stored. During online communication, the TAPCON®-trol software installed on a PC establishes the regulator ID and compares this with the regulator IDs already stored.

7.4.2.4 Setting the switching pulse time

This display can be used to set the duration of the switching pulse for the mo-tor-drive unit.

If you set the raise or lower switching pulse time to 1.5 seconds for example, after the set delay time T1 or T2 there will be a switching pulse of 1.5 seconds.

The waiting time between 2 consecutive switching pulses corresponds to the set delay time T1 or T2.



Figure 38 Switching pulse in standard operating mode

1 Set delay time T1

2 Start of first raise/lower switching pulse

3 Switching pulse time Ti (1.5 seconds)

4 Start of second raise/lower switching pulse

In rapid return control mode the next switching pulse can only take place after 1.5 seconds.

reduce it.

3. Press .

The delay time for function monitoring is set.



7.4.2.9 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 tap-change 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 tap-change 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)



7.4.2.10 Wiring and parameterizing control input/output relay

If you want to monitor the motor runtime, the voltage regulator and motor-drive 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 protec-tive switch is switched back on and activates the "Motor protective switch tripped" message.

To activate "Local" or "Remote" operating mode, proceed as follows:


11x .

<11> Local / Remote.

2. Press or to to activate "Local" (ON)

or "Remote" (OFF) operating mode.

3. Press .

The operating mode is set.

7.4.3 Configurable inputs and outputs

You can individually configure the digital inputs (GPI) and outputs (GPO).

The following digital inputs and outputs are available:

6 digital inputs (GPIs 1...6)

2 digital outputs (GPOs 1...2)



7.4.3.1 Assigning function to inputs (GPIs)

You can activate the inputs as follows:

Statically using signal statuses

The input signal must be continually present (status: high level).

Dynamically using pulses

A pulse (rising edge) is needed at the input. The input signal must change its status from "Low" to "High". If you are using a pulsed input, you can trigger the assigned function in parallel, e. g. via the control system and at buttons connected to the inputs.

You can recognize pulsed inputs from the preceding "P:". The note "Warning: P = pulsed inputs" is displayed on the screen.

You can assign one of the following functions to each of the digital inputs (GPIs 1...6):

Function Description

Off No function selected.

Remote/Local Define Remote/Local operating mode. Signal on: "Remote" operating mode active. Signal off: "Local" operating mode active.

Blocking Block automatic regulation.

Quick Tap Activate high-speed return (deactivate T1/T2) (page 96).

Desired value 2 Activate desired value 2.

Desired value 3 Activate desired value 3.

Blk U raise Block tap-change operations (raise).

Blk U lower Block tap-change operations (lower).

P: DV 1 Activate desired value 1.



Table 40 Functions for digital inputs (GPIs 1...6)



If 2 inputs are assigned the same functionality (e.g. activate desired value 2), the device produces an event message (page 159). This also applies if you assign the same functionality via a static input (e. g. GPI 1 = "Desired value2") and via a pulsed input (e. g.GPI 2 = "P: SW 2").

To assign a function to digital input GPI 1 (on X4:13) or to deactivate it, pro-ceed as follows (example: GPI 1 - X4:13):
