When the pre-heat time is up, the pre-heat indicator (DL)
goes out (If the start switch is turned off during the pre-heat
time, the controller will stop) and the pre-heat system then
wait to start the engine for 30s.
• During the waiting time (the pre-heat plug is in ON posi-
tion),if you switch on the start switch (K2),the fuel supply
valve is open and the pre-heat indicator will be lighted on
again with the pre-heat plug energized .
• During the waiting time, if you don’t switch on the start
switch (K2) , the voltage of 24V will not be input to 50 port
which means that the engine is not started .The controller
will stop working.
4. If the generator don’t send D+ signal to the controller after the
reset of the start switch, which means that the engine fail to
be started, the control will stop working after 6s;if the gener-
ator send D+ signal to the control (which means that the en-
gine is started),it begin to heat and the heat time is presented
as a function of the resistance of the engine coolant sensor
whose range is between 60s and 120s.
5. If the circuit of the engine coolant sensor is open, the pre-
heat system works. The pre-heat indicator twinkle for 15s to
give a warning after all start procedure is over, and it is the
longest heating time.
6. When the voltage is less than 15V, the pre-heat system
doesn’t work and the pre-heat indicator (DL) twinkle for 15s
to give a warning.
7. No matter the controller stop working at what stage, only
turning off the pre-heat switch K1, which means cancel the
voltage of 15V, firstly and then turning it on can regain the
pre-heat function.
