AUTOMATIC START/STOP OPERATION
4.3.1
ILLUSTRATION
Auto mode is activated by pressing
action.
4.3.2
AUTO START SEQUENCE
a)
Start Conditions:
Mains enable: when mains abnormal situations (over/under voltage, over/under frequency,
loss of phase, reverse phase sequence) occur, then it enters into "Mains Abnormal Delay",
LCD status page displays countdown; When mains abnormal delay is over, it enters into "Start
Delay"; or remote start (on-load) input is active, it enters into "Start Delay";
Mains disable: when remote start (on-load) input is active, it enters 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 crank relay outputs; if genset
fails to start during "Crank Time", the fuel and crank 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 mains abnormal starts or HGMS62 remote start (on-load) inputs, if "Warming Up Delay" is
over, the indicator will illuminate if gen is normal. If genset voltage and frequency reach the load
requirement, the closing relay outputs, genset is taking load and indicator illuminates, genset
enters normal running; if genset voltage or frequency is abnormal, controller will send alarm and
shutdown (LCD displays the alarm information).
NOTE: When remote start (off-load) inputs, the procedure is same as above, only in h), gen close relay not outputs, genset
not take load.
4.3.3
AUTO STOP SEQUENCE
a)
When HGMS62 is normally running, if mains recovers normal, it enters into "Mains Voltage Normal
Delay", mains indicator illuminates after confirming mains normal, "Stop Delay" begins; or when
remote start input is inactive, then "Stop Delay" begins;
b)
When "Stop Delay" is over, genset enters into "Cooling Delay", and gen closing relay is
disconnected; after "Breaker Transfer Delay", mains close relay outputs, mains takes load, gen
supply indicator distinguishes, mains supply indicator illuminates;
c)
When entering "Stop Idle Delay" (if configured), idle relay is energized to output;
