NOTE:
If any of the mode forcing inputs Remote OFF, Remote MAN, Remote AUT or
Remote TEST is active, then the currenly active mode can be different than the
mode selected by the setpoint (resp. panel buttons).
OFF
The GCB is opened and the engine is immediately stopped in this
mode without unloading and cooling. After that the controller is in
Not ready state and can not be started any way. The MCB is closed
permanently (MCB Opens On = GENRUN) or is open or closed
according to the mains is present or not (MCB Opens On =
MAINSFAIL).
MAN
The engine can be started and stopped manually using START and
STOP buttons (or external buttons wired to appropiate binary inputs)
in MAN mode. When the engine is running, GCB can be closed to a
dead bus or synchronizing can be started by the GCB button. Also
MCB can be closed and opened manually using the MCB button,
regardless the mains is present or not. No autostart is performed. No
reaction to the inputs Sys Start/Stop or Rem Start/Stop.
SEM
(IS-NT only) - The gen-set is started and stopped only manually
using START and STOP buttons (or external buttons wired to
appropiate binary inputs), however the the full start sequence up to
the moment when the engine is loaded is automatic as well as
unloading and stop sequence. The only case when the gen-set
starts automatically in SEMI is the start/stop initiated by the AMF
function.
AUT
This is fully automatic operation. The engine is started and stopped
by:
• Binary input Rem Start/Stop (SPtM, SPI, COMBI)
• Mains import dependent autostart function (peak start/stop)
(SPtM, SPI, Combi)
• AMF function (SPtM, Combi)
• Power management (MINT, Combi)
Buttons MCB, GCB, START, STOP including the appropriate binary
inputs for external buttons are not active. The full start sequence up
to the moment when the engine is loaded is automatic as well as
unloading and stop sequence.
WARNING!
If an red alarm is present and the gen-set is in AUT mode, it can
start by self after all red alarms becomes inactive and are
acknowledged!!! If you want to avoid this situation, adjust the
setpoint FltRes GoToMAN to the ENABLED position.
TEST
(SPtM, Combi) - the gen-set is started when the controller is
switched to TEST mode and remains running unloaded until the
mode is changed. If a mains failure occurs, the gen-set takes over
the load.
Setpoint: FltRes GoToMAN
