In normal operation the overvoltage trip signal is activated and the undervotage trip
signal is deactivated. This means that the overcurrent function is blocked.
When the generator is taken out of service the generator voltage gets low. The
overvoltage trip signal will be deactivated and the undervoltage trip signal will be
