Parameter Definition

Unit

Fact.Set

Description

P_029

Hysteresis Voltage

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

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

This parameter defines the delay after the engine

runs and before the fault monitoring is enabled.

P_032

Overload Timeout

sec

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

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

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

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

The gas solenoid of the gas engine will be opened

after this delay during cranking.

P_037

Crank Timer

sec

This is the maximum start period. Starting will be

automatically cancelled if the genset fires before

the timer.

P_038

Wait Between Starts

sec

This is the waiting period between two start

attempts.

P_039

Idle Speed Timer

sec

When the engine runs, the Idle output relay

function will be active during this timer.

P_040

Engine Heating Timer

sec

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.
