3.2.23 POLARITY OF HIGH WATER TEMPERATURE INPUT (ATA)
NOTE
Some engines require special delays between the activation of the stop by
de-excitation signals and start-up and even though the preheating is disabled,
the control unit can perform delays of several seconds before start-up after
receiving the order to start up. If the application requires an immediate start-up
without preheating, disable the preheating and also set the preheating time to 0.
3.2.20 COOLING ENABLING (READING ONLY. SELECTION BY MICROSWITCH 5)
Enables or disables the cooling phase in the genset shutdown cycle.
3.2.21 DETECTION OF ENGINE STARTED BY BATTERY CHARGING ALTERNATOR (D+)
(READING ONLY. SELECTION BY MICROSWITCH 6)
If you disable detection by alternator battery charge (OFF), engine started detec-
tion should only be carried out by frequency reading (Generator set or Pick-Up).
NOTE
The engine started detection is always performed by frequency reading, whether
by Generator set or by Pick-Up. Activating this microswitch adds detection by D+,
in which case the engine started detection is performed simultaneously by
frequency reading and by D+. If no rated speed has been stored, the control unit
will consider that the genset has started when the frequency of the generator
set signal is greater than 20Hz, as long as frequency reading by generator set
has been selected.
3.2.22 DETECTION OF SHUTDOWN DUE TO LOW OIL PRESSURE
If this option is activated, the control unit will not consider that the engine has
stopped until the oil pressure has dropped. Until then it will not allow the engine
to be started up again.
3.2.24 POLARITY OF LOW OIL PRESSURE INPUT (BPA)
3.2.25 POLARITY OF AUXILIARY INPUT (AUX)
3.2.26 POLARITY OF FREE VOLTAGE INPUT (LT)
3.2.27 POLARITY OF RESERVE FUEL INPUT (RC)
The polarity of the inputs is congurable, which allows it to be activated at a high
or low level.
3.3 CONFIGURATION USING MICROSWITCHES
Allows you to modify the behaviour of the control unit using the microswitches, to
adapt to all types of units. By default, the control units come with the 8 mi
croswitches in the OFF position.
3.3.1 LONG PREHEATING (SW1)
The functionality of this microswitch is conditioned by the position of microswitch
4 (SW4) "Enabling Preheating".
SW1 SW4 Preheating
OFF OFF
Preheating determined by parameter P4 "Preheating Time" (set to zero by
default).
ON OFF
OFF ON Short preheating (5 seconds)
ON ON Long preheating (10 seconds)
3.3.2 FREQUENCY DETECTION BY PICK-UP (SW2)
SW2 Operation
OFF Frequency detection by generator (GEN)
ON Frequency detection by PICK-UP (PCK)
