TEST mode (SPtM only)
Use TEST mode for Gen-set start test if the Mains is OK or to transfer the load to the gen-set when
Mains fail is announced in advance.
Hint:
The controller does not respond to GCB ON/OFF , STOP, START in
Ret from test
= AUTO.
Engine automatically starts, when TEST mode is selected.
Engine can start automatically without warning when pressing FAULT RESET after shut down alarm.
Baseload
Process control:
Load ctrl PtM =
BASELOAD
Gen-set power is kept at value given by
Process control
:
Base load
setpoint.
Internal Import export
ProcessControl:
Load ctrl PtM
= IMP/EXP
Process control:
IE measurement =
IM3 CT INPUT
Gen-set power is controlled to keep the import load at the level given by setpoint
Process control:
Import load
value.
Controller measures
Import/Export value via current transformers connected to In/Im3 terminal. The
value of L3 is then multiplied by 3 to give an estimation of the actual Imp/Exp.
