Parameter Definition
Unit
Fact.Set Description
P_029
Hysteresis Voltage
V
8
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.
P_030
Engine Heating
Temperature
°C
0
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.
P_031
Fault Holdoff Timer
sec
12
This parameter defines the delay after the engine
runs and before the fault monitoring is enabled.
P_032
Overload Timeout
sec
5
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.
P_033
Engine Start Delay
sec
0
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.
P_034
Preheat Timer
sec
1
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
)
P_035
Choke Timer
sec
5
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).
P_036
Gas Solenoid Delay
sec
5
The gas solenoid of the gas engine will be opened
after this delay during cranking.
P_037
Crank Timer
sec
10
This is the maximum start period. Starting will be
automatically cancelled if the genset fires before
the timer.
P_038
Wait Between Starts
sec
10
This is the waiting period between two start
attempts.
P_039
Idle Speed Timer
sec
0
When the engine runs, the Idle output relay
function will be active during this timer.
P_040
Engine Heating Timer
sec
4
This is the period used for engine heating
following the program parameter.
P_041
Mains Waiting Timer
min
0.5
This is the time between the mains voltages
entered within the limits and the generator
contactor is deactivated.
P_042
Cooldown Timer
min
1.0
This is the period that the generator runs for cooling
purpose after the load is transferred to mains.
