GU320a Controller Manual
8
When the remote control start signal valid, the start delay will active and begin to time. During the delay, if the remote
start signal invalid, start delay will instantaneously stop, the controller will stop the start procedure, and return to original
state“READY” after the time for fail to start out.
During cranking or idle, if the remote control start input signal is invalid, the controller stop the followed start
procedure and close all output for relay control, then stop the start process and return to original state“READY” after the
time for fail to start out.
Note: when cranking, the engine ignited, while the alternator output frequency reach the preset frequency, the start
motor de-energized:
Or de-energized the motor through the following way
a、 The magnetism speed pickup device mounted on the flywheel of the engine has detected the frequency reached preset.
b、 The output voltage of the alternator reach 80% of the rated voltage.
c、 The low oil pressure switch of the engine open.
5.3
Fail to Start and Restart Condition:
Operation Description
During the cranking time, engine igniting is forbidden, and the controller
remains crank intermission, it will not output starting signal. FAIL
TO START indicator light flash.
CRK-RST
00:04
Once the crank intermission reach, the controller will attempt to start the
engine again.
CRANK 2
The phenomena above repeat again and again, until the engine reach the normal running parameters. While
starting, if any stop fault occurs, the controller will stop controlling output instantly until the fault eliminated
and reset, then it can be operated again.
5.4
Fail to start condition:
Operation Description
When the phenomena above repeat again and again, the starting attempts
exceed preset , the controller will stop controlling output. Then the LCD
display:
ALARM:
START FAILURE
NOTE:
If it occurs FAIL TO START fault, the operator must check the whole
“Genset” system. and confirm the fault and eliminate them, then press
“ STOP/RESET” key to unlock the fault-locking state, and reset the
controller again.
5.5 Auto stop process
Operation Description
When the remote start input signal is invalid, the cooling delay begin to
count down, the running signal cut and the LCD then display:
COOL
02:34
While the cooling delay timeout, the controller disconnect the fuel valve, and
count down for Fail To Stop, then the LCD display:
STOP
00:24
While the Fail To Start timeout, if the engine still run, the controller will
sent an alarm, and the LCD display:
ALARM:
STOP FAILURE
If the engine stop during the fail to stop permission delay, the LCD will display:
READY
When the remote control start input signal is invalid, the cool delay begin, if the remote control start input signal is
valid during the delay, the cooling delay time stop instantaneously, the controller monitor each parameter again, and reset
Auto running state if normal.
5.6
Stop by “MAN”
