Maschinenfabrik Reinhausen GmbH 2018
To set the delay time for the parallel operation error message, proceed as
follows:
1. Go to Settings > Parameters > Parallel operation > Delay time for the
parallel operation error message.
2. Enter the delay time.
3. Press the Accept button to save the modified parameter.

8.10 Monitoring functions

For various measured values, you can define limit values that are monitored
by the device.
For monitoring the transformer's current output voltage, you can set 4 limit
values:
▪ Undervoltage U<<: Lower limit 2
▪ Undervoltage U<: Lower limit 1
▪ Overvoltage U>: Upper limit 1
▪ Overvoltage U>>: Upper limit 2
If the measured value is higher than the upper limit (> or >>) or lower than
the lower limit (< or <<), the device reacts in accordance with the Behavior
parameter.
