Requirements The following requirements must be ful fi lled:
● an operational generator
● generator started
During heavy loads, such as starting current or impact loads, the
drive engine’s centrifugal governor quickly reaches its limit. The
throttle opens all the way and this ensures that the engine’s full
power is available.
Switching on and off is automatic.
