The unit provides a special function for the fuel solenoid control of a gas engine.
The fuel solenoid of a gas engine is different from a diesel engine. It should be opened after
the cranking has been started and should be closed between crank cycles. The delay between the
crank start and solenoid opening is adjusted using the
Gas Solenoid Delay
program parameter.
The gas engine fuel solenoid relay function may be assigned to spare relays using
Relay
Definition
program parameters. Also relays on an extension module may be assigned to this function.
The load shedding feature consists on the disconnection of the least crucial loads when the
genset power approaches to its limits. These loads will be supplied again when the genset power falls
below the programmed limit. The internal Load Shedding function is always active. Any of the auxiliary
relays may be used as the load shedding output.
The dummy load function consists on the connection of a dummy load if the total genset load
is below a limit and to disconnection of the dummy load when the total power exceeds another limit.
The dummy load function is the inverse of the load shedding function, thus the same output may be
used for both purposes.
The parameters used in Load Shedding feature are in the Electrical Parameters Group:
Load Shedding Low Limit:
If the genset active power output goes below this limit, then the Load
Shedding relay will be deactivated.
Load Shedding High Limit:
If the genset active power output goes above this limit, then the Load
Shedding relay will be activated.
