Pgm Definition Unit Std Val Description
20 Temperature sender type - 1 This parameter selects the temperature sender
type:
0: The sender characteristics are defined in
table using parameters P_143 to P_154.
1: VDO
2: DATCON DAH type
3: DATCON DAL type
21 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
P_004 . When the mains
fail, the low limit will be used as P_004+P_021 .
It is advised to set this value to 8 volts.
22 Not used
23 Holdoff timer sec 8 This parameter defines delay after the engine
runs and before the fault monitoring is enabled.
24 Overcurrent / Excess
Power / Frequency Timer sec 3 This is the period between the current or active
power goes over the limits
(P_002/P_003) and
OVERLOAD alarms occurs.
This is also the period between the frequency
goes out of the limits (
P_008/P_011) and SPEED
FAULT alarm occurs.
25 Not used
26 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 defined by programming)
27 Start Timer sec 6 This is the maximum start period. Starting will
be automatically cancelled if the genset fires
before the timer.
28 Wait between Starts sec 10 This is the waiting period between two start
attempts.
29 Engine Heating Timer sec 3 This is the period after the engine runs and
before the Genset Ready signal is issued.
30 Not used
31 Cooling Timer min 1.0 This is the period that the generator runs for
cooling purpose after the load is transferred to
mains.
32 Not used
33 Not used
34 Stop Timer sec 10 This is the maximum time duration for the
engine to stop. During this period the STOP
relay output is energized (if defined by
programming). If the genset has not stopped
after this period, a
STOP FAIL alarm will occur.
35 Start Attempts - 3 This is the maximum number of start attempts.
36 Horn Timer sec 10 This is the period during which the HORN relay
is active. If the period is set to 0, this will mean
that the period is unlimited.
37 Not used
