– AMF without advanced synchronization:
When the mains current returns, the unit
switches to mains supply, cooling and stopping
the generator set.The mains supply return is
made without advanced synchronization when
the adjusted "waiting time of mains current
OK" expires.
– AMF with advanced synchronization:
When the mains current returns, the unit
synchronizes the mains circuit breaker with
the busbar when the "waiting time of mains
current OK" expires.After this, the generator
set cools and stops.
Running with Peak Shaving (PS)
This application is normally used in combination
with the AUTO mode.Installation with mains
current.
The generator starts if the power from the current
imported from the mains (measured with an
optionalcurrent transducer = PT) exceeds the
defined level.The generator synchronizes itself with
the busbar and supports the load until the value
defined for the imported mains current is achieved.
If the imported mains current power decreases
below the defined level of the imported current
power, the generator unloads and disconnected itself
from the bus.Then it enters in the running-in mode.
Running with Fixed Power (FP)
This application is only possible in combination
with the SEMI-AUTO or AUTO modes.It is
normally used in combination with the SEMI-
AUTO mode in installations with mains
current.The real-time internal clock can only be
used in theAUTO mode.
The generator delivers a fixed power to the load or
the mains current.
Load Take Over (LTO) running
This application is normally used in combination
with the SEMI-AUTO or AUTO mode in
installations with mains current.
The purpose of the load take over mode is to
transfer load imported from the mains to the
generator set, just for running with the generator
current.
The generator is started, synchronized and gradually
released from the current load before opening the
current circuit breaker.To make sure that the mains
current was fully substituted, an optional power
transducer is required.
Mains power export (MPE) running
This application is only possible in combination
with the SEMI-AUTO or AUTO modes.The real-
time internal clock can only be used in theAUTO
mode. The installation is run with mains current.
The mains power export mode can be used to keep
a constant power level by means of the mains circuit
breaker.The power can be exported to the mains
or imported from the mains, but always at a
constant level.
