3.4.2 AMF (no back synchronisation)
Auto mode description
The unit automatically starts the genset and switches to generator supply at a mains failure after an adjusta-
ble delay time. It is possible to adjust the unit to change to genset operation in two different ways:
1. The mains breaker will be opened at genset start-up.
2. The mains breaker will remain closed until the genset is running, and the genset voltage and frequency is
OK.
In both cases, the generator breaker will be closed when the generator voltage and frequency is OK, and the
mains breaker is open.
When the mains returns, the unit will switch back to mains supply and cool down and stop the genset. The
switching back to mains supply is done when the adjusted "Mains OK delay" has expired.
For a general description of the available running modes, please refer to the chapter "Running
mode description".
