14. 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 20sec-
onds.
15. Press to select manual mode.
16. Set the delay time T2 to 10seconds and activate it [►Page 117].
17. Press twice to raise the on-load tap-changer two steps.
18. Press to select auto mode.
ð If the actual voltage is outside the bandwidth, after 20seconds the de-
vice lowers the on-load tap-changer one step and after another
10seconds another step.
19. Press to select manual mode.
20. Set the delay time T1 [►Page 115] and delay time T2 [►Page 117] to
the desired value.
We recommend a temporary setting of 100seconds for 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 how the actual voltage progresses and the
number of tap-change operations per day.
8.2.3 Checking parallel operation
To ensure that parallel operation functions correctly, the device must be
commissioned in independent mode. Make sure that the conditions below
have been met.
▪ All devices are set to the same operating parameters for "desired value"
and "delay time T1" [►Page 115]
▪ The "Activate parallel operation" parameter is set to ON
▪ The desired Parallel operation method is selected.
▪ A different CAN bus address (≠0) is set for all devices.
▪ All devices are in the same parallel operation group:
– With parallel operation detection via group input: A signal is present at
the same group input on all devices.
– With parallel operation detection via topology: The circuit breakers are
configured and connected so that the devices participate in parallel op-
eration.
