7.5.1 Checking measured values and status of digital inputs and
outputs
Upon commissioning the device, check whether the measured values and
status of digital inputs and outputs are plausible. To do so, use an additional
measuring device if necessary in order to check the individual measured val-
ues.
To display the status of the digital inputs and outputs, proceed as follows:
1. Go to Information > Hardware.
2. Select the individual assemblies one after another and check the individ-
ual measured values or the status of digital inputs and outputs.
3. If errors arise, check the measurement path and the wiring [►Section 6.6,
Page 57].
7.5.2 Testing a control function
This section describes how you can check the device's control functions:
ü Supply voltage must be present.
1. Press to select manual mode.
2. Set transmission ratio for voltage transformer, current transformer, and
transformer circuit.
3. Measure actual voltage and compare with the measured value displayed
on the device's main screen.
4. Select the Measured values menu item to display the operating values
for current and power and compare them with the values of the operation
measurement instruments.
5. Control the on-load tap-changer manually using the or keys
until the measured voltage U
actual
reaches the desired voltage U
desired
("de-
sired value 1").
6. Set desired value to the value you want [►Section 8.12.1, Page 138].
7. Set bandwidth depending on step voltage [►Page 151].
8. Set delay time T1 to 20 seconds [►Page 152].
9. Set time response T1 to linear [►Page 152].
10. Press to raise the on-load tap-changer 1 step.
11. Press to select auto mode.
ð If the actual voltage is outside the bandwidth, the device returns the
on-load tap-changer to the original operating position after 20 sec-
onds.
12. Press to select manual mode.
13. Press to lower the on-load tap-changer 1 step.
