5.4.3 Operating Modes
Selecting the operating mode is done through Left and Right buttons on the front panel or by changing the
Controller mode (page 152) setpoint (from the front panel or remotely).
Note: If this setpoint is configured as password-protected, the correct password must be entered prior to
attempting to change the mode.
Note: The mode cannot be changed if Access Lock input is active.
The following binary inputs can be used to force one respective operating mode independent of the mode
setpoint selection:
Remote OFF (page 311)
Remote TEST (page 313)
Remote MAN (page 311)
Remote AUTO (page 310)
If the respective input is active the controller will change the mode to the respective position according to the
active input. If multiple inputs are active, the mode will be changed according to priorities of the inputs. The
priorities match the order in the list above. If all inputs are deactivated, the mode will return to the original
position given by the setpoint.
OFF
No start of the gen-set is possible .Controller stays in Not ready status and cannot be started any way. The
MCB is closed permanently (MCB Opens On (page 207) = GENRUN) or is open or closed according to whether
the mains is present or not (MCB Opens On (page 207) = MAINSFAIL). No AMF function will be performed. The
buttons MCB , GCB , Start and Stop including the appropriate binary inputs for external buttons
are not active.
IMPORTANT: When engine is running, it is not possible to switch gen-set to OFF mode.
MAN
The engine can be started and stopped manually using the Start and Stop buttons (or external buttons
wired to the appropriate binary inputs) in MAN mode. When the engine is running, GCB can be closed. Also
MCB can be closed and opened manually using the MCB button, regardless of whether the mains are present or
not. No auto start is performed.
Note: The controller provides interlock between GCB and MCB, it means it is never possible to close both CB
together.
AUTO
The controller does not respond to buttons Start , Stop , MCB ON/OFF and GCB ON/OFF . Engine
start/stop request is evaluated form Mains failure/return.
Note: When the AMF function will start the engine than the engine will be running at least for the time which is
defined in Mains Return Delay (page 200) setpoint, even if the mains would return in the meantime.
