4.4.1
LOW POWER CONSUMPTION OPERATION
Controller applies low power consumption method at hardware aspect, which reduces the power
consumption greatly in the period of stop. With this battery cost is larged decreased, because it reduces
the battary change times.
Controller has true low consumption (power off) and feign low consumption (awakening, LCD light not on,
only stop indicator flashing, not do any action).
a. Power on the controller, and controller is running as usual;
b. After power on, press
and controller enters normal runningl if
is not pressed,
controller will judge the status according to the last stop situation; If controller is stopped manually, it
will enter true low consumption as remote start signal is inactive; if it is active, controller enters feign
low consumption; Otherwise, controller will run normally.
c.
In standby status, Press
for 3s and controller will be powered off.
NOTE 1
: When low consumption time is set to 0, controller will not enter it automatically (base pin of power control is
always energized).
NOTE 2
: When low consumtion time is not set to 0, if genset is in the standby mode and doesn't have data communication,
controller will enter low consumtion based on the set low consumption time.
4.4.2
INSTRUCTION
Press
and the indicator beside will be on, which means genset is in the auto mode.
4.4.3
AUTO START SEQUENCE
a. When remote start signal is active (Terminal No. 6 connects B-),
“Start Delay” time is initiated;
b. When start delay is over, preheating relay outputs (if configured),
“preheat delay” is initiated;
c.
After the above delay, the fuel relay outputs, and one second later, the start relay outputs; During the
starting time if the genset fails to start, fuel relay and start relay stop outputting, enter “Crank Rest
Time” and wait for next start;
d. If the genset fails to start during the set starting attempts, LCD displays
and it means start
failure alarm and meanwhile alarm indicator flashes;
e. If the genset starts successfully during the starting attempts, it enters
“Safety On” time, during which
low oil pressure, water temperature high alarms
are inactive; After “Safety On” time, it enters “Start
Idle Delay” (if configured);
f.
During “Start Idle Delay”, under speed, under frequency and under volt alarms are all inactive; When
this delay is over, “Warming Up Delay” is initiated (if configured);
g.
After the “warming up delay”, genset will enter into Normal Running status. If genset voltage or
frequency is abnormal, controller will issue shutdown alarm and stop the genset.
