Genset mode
This menu is used to change the mode of the machine.
In the Qc2002™ module 2 application modes can be
selected:
Island operation
– This operation type is selected for local/remote
start applications, without the Mains (= stand-
alone).
• Combined with Manual Operation mode =
Local Start operation.
• The sequences start/stop/close Generator
Contactor / open Generator Contactor can be
activated manually.
• Combined with Automatic Operation mode =
Remote Start operation.
– The remote start signal can be given with an
external switch. After the generator has been
started, the Generator Contactor will close
automatically.
– Installation wirings for Remote Start operation:
wire the RS switch between X25.9 & X25.10.
Automatic Mains Failure (AMF) operation
– This application is only possible in combination
with the Auto mode. If the Manual Operation
mode is selected the AMF operation will NOT
function !
– When the Mains exceeds the defined voltage /
frequency limits for a defined delay time, the
generator will take over the load automatically.
– When the mains is restored within the defined
limits for a defined time, the generator will unload
before disconnecting and switching back to the
Mains.
– The generator will then go into cooldown and
stop.
– Installation wirings: we refer to circuit diagram
