AUTOMATIC START/STOP OPERATION
4.3.1 ILLUSTRATION
Auto mode is activated by pressing the
, LED indicator beside the button is illuminating which
confirms this action.
4.3.2 AUTO START SEQUENCE
a)
Start Conditions:
Mains AMF enable:
when there is no mains power, then enter into “Start Delay”; or remote
start input is active, then enter into “Start Delay”;
Mains unused:
when remote start (on load) input is active, then enter into “Start Delay”;
b)
“Count- down” of start delay is displayed on LCD
；
c)
When start delay is over, preheating relay is outputting (if configured), “Preheating Delay XX s” is
displayed on LCD
；
d)
When preheating delay is over, fuel relay is outputting for 1s and then start relay outputs; if genset
fails to start during “Crank Time”, the fuel and start relay will stop outputting and enter into “Crank
Rest Time” and wait for next cranking;
e)
If genset fails to start within set start times, the controller will send shutdown alarm of start failure
and display the alarm on LCD;
f)
Any time to start genset successfully, it will enter into “Safe Running”. During this period, alarms of
low oil pressure, high water temperature, under speed, failed to charge are disabled. As soon as
this delay is over, genset will enter into “Start Idle Delay” (if configured).
g)
During start idle delay, alarms of under speed, under frequency, under voltage are disabled. As
soon as this delay is over, genset will enter into “Warming Up Delay” (if configured).
h)
When “Warming Up Delay” is over, the indicator will illuminate if gens is normal. If voltage and
frequency of engine reach the load requirement, the closing relay outputs, genset is taking load
and indicator illuminates; if engine voltage or frequency is abnormal, controller will alarm and
shutdown (LCD displays the alarm information).
4.3.3 AUTO STOP SEQUENCE
a)
Stop Conditions
Mains AMF Enable:
during gens normal running, if mains returns to normal and remote start
input is inactive, then “stop delay” begins;
Mains unused:
when remote start input is inactive, then “stop delay” begins;
b)
When “Stop Delay” is over, genset enters into “Cooling Delay”, and gens closing relay is
disconnected;
c)
When entering “Stop Idle Delay” (if configured), idle relay is energized to output;
d)
When entering “ETS Delay”, ETS relay is energized to output, fuel relay output is disconnected and
automatically judge if it has stopped;
e)
When entering “Genset at Rest”, genset will automatically judge if it has stopped.
f)
When genset has stopped, enter into standby mode; if genset fails to stop, controller will alarm
(“Fail to Stop” alarm will be displayed on LCD).
