This parameter provides the mains and genset
voltage limits with a hysteresis feature in order to
prevent faulty decisions.
For example, when the mains are present, the
mains voltage low limit will be used as the
programmed low limit. When the mains fail, the
low limit will be incremented by this value. It is
advised to set this value to 8 volts.
Engine Heating
Temperature
If it is requested that the engine runs without load
until reaching a certain temperature, this
parameter defines the temperature.
If the coolant temperature falls below this
parameter, an Engine Low Temperature warning
will occur.
This parameter defines the delay after the engine
runs and before the fault monitoring is enabled.
This is the period between the current or active
power go over the limits and OVERCURRENT or
EXCESS POWER Load Dump alarms occur.
This is also the period between the frequency goes
out of the limits and OVERSPEED or
UNDERSPEED alarms occur.
This is also the period between the genset voltage
goes out of the limits and HIGH VOLTAGE or LOW
VOLTAGE alarms occur.
This is the time between the mains fails and the
fuel solenoid turns on before starting the genset. It
prevents unwanted genset operation in battery
backed-up loads.
This is the time after the fuel solenoid is energized
and before the genset is started. During this
period the PREHEAT relay output is energized (if
assigned by Relay Definitions)
This is the control delay of CHOKE output.
The choke output is activated together with the
crank output. It is released after this delay or when
engine runs (whichever occurs first).
The gas solenoid of the gas engine will be opened
after this delay during cranking.
This is the maximum start period. Starting will be
automatically cancelled if the genset fires before
the timer.
This is the waiting period between two start
attempts.
When the engine runs, the Idle output relay
function will be active during this timer.
This is the period used for engine heating
following the program parameter.
This is the time between the mains voltages
entered within the limits and the generator
contactor is deactivated.
This is the period that the generator runs for cooling
purpose after the load is transferred to mains.
