When the REMOTE START signal arrives, the engine starts to run but the unit gives START
FAIL alarm and then the engine stops:
-The generator phase voltages are not connected to the unit. Measure the AC voltage between
terminals
GEN L1
and
Generator Neutral
at the rear of the unit while the engine is running. A fuse
protecting the generator phases may be failed. A misconnection may be occurred. If everything is OK,
turn all the fuses off, and then turn all the fuses on, starting from the DC supply fuse. Then test the
unit again.
The unit is late to remove engine cranking:
-The generator voltage rises lately. Also the generator remnant voltage is below 20 volts. The unit
removes starting with the generator frequency, and needs at least 20 volts to measure the frequency.
If this situation is to be avoided, the only solution is to add an auxiliary relay. The coil of the relay will
be between BATTERY (-) and charging alternator D+ terminal. The normally closed contact of the
relay will be connected serially to the unit's START output. So the starting will also be removed when
the D+ pulls to battery positive.
The unit is inoperative:
Measure the DC-supply voltage between
BAT+
and
BAT-
terminals at the rear of the unit. If OK, turn
all the fuses off, then turn all the fuses on, starting from the DC supply fuse. Then test the unit again.
Some program parameters are skipped:
These parameters are reserved for factory setting and cannot be modified.
