4.3 AUTO START/STOP OPERATION
4.3.1 AUTOMATIC START SEQUENCE
a) Press
and indicator besides it illuminate, which means pump unit is in Auto Start mode.
b) If remote input is active, controller
“Start Delay” begins countdown, meanwhile, “Remote Start
Warning
” displayed on the LCD of controller with the buzzing sound of buzzer (remind people
keep away).
c) When start delay is over, buzzing sound stops and preheat relay energizes (if configured),
“preheat delay XX s” information will be displayed on LCD;
d) After the above delay, the Fuel Relay is energized, and then one second (pre-set fuel time before
crank) later, the Start Relay is engaged. If the pump unit fails to fire during this cranking attempt
then the fuel relay and start relay are disengaged for the pre-
set rest period; “crank rest time”
begins and wait for the next crank attempt.
e) Should this start sequence continue beyond the set number of attempts, the start sequence will be
terminated, the Fail to Start fault will be displayed on LCD.
f)
In case of successful crank attempt, the “Safety On” timer is activated, allowing Low Oil Pressure,
High Temperature,
“Under Speed” and “Charge Alternator Failure” inputs to stabilize without
triggering the fault. As soon
as this delay is over, “start idle” delay is initiated (if configured).
g)
During “start idle” delay, under speed alarm is deactivated. When this delay is over, “warming up”
delay is initiated (if configured).
h)
After the “warming up” delay, pump unit will enter into Normal Running status. If engine speed is
abnormal, controller will shutdown with alarms (alarm information will be displayed on alarm page
of LCD).
4.3.2 AUTOMATIC STOP SEQUENCE
a) When remote start signal is deactivated and remote stop signal is active,
“Stop Delay” timer is
initiated.
b)
Once this “stop delay” has expired, the “Cooling Delay” starts. If remote start signal is active again
during cooling delay, pump unit will enter into running status again. When cooling delay expired,
pump unit enters into
“Stop Idle” delay.
c)
During “Stop Idle” Delay (if configured), idle relay is energized.
d)
“ETS Solenoid Hold” begins, ETS relay is energized while fuel relay is de-energized.
e) "Wait for Stop Delay" begins, and complete stop is detected automatically.
f)
Pump unit is
placed into its “After stop time” after its complete stop. Otherwise, fail to stop alarm is
initiated and the corresponding alarm information is displayed on LCD (If pump unit stopped
successfully after “Failed to Stop” alarm, it will enter “After stop time” and remove alarm).
