Remedial Actions
Possible Issues in MANUAL Mode
1
The controller does not power
ON.
•
Check the battery voltage.
•
Check the fuse on the battery supply.
•
Check continuity between battery positive and
controller terminal # 2.
•
Check continuity between battery ground and
controller terminal # 1.
2
The controller fails to crank-
start the engine.
•
Check the battery voltage.
•
Enter “configuration mode” in controller and verify the
configuration for the “Start Relay” output. Also, check
that “Start Relay” output is working correctly by
measuring its output voltage.
•
Enter “configuration mode” in controller and verify the
configuration of “CRANK DISCONNECT” method.
•
Verify the configuration of “LLOP SWITCH” polarity.
Also, ensure that the 3+2n/4+2n switch & sensor are
working OK. Check their wiring.
3
The “Emergency Stop” alarm
comes up even when the
“Emergency Stop” is not
pressed.
•
Check if the “Emergency Stop” switch is working OK.
Check its wiring also.
•
Enter “configuration mode” in controller and verify the
configuration of “EMERGENCY STOP” polarity.
4
The controller generates
unnecessary “Shutdown
Alarms” or “Warning Alarms”
•
Check the respective switch/sensor and wiring.
•
Enter “configuration mode” in the controller and verify
the respective threshold configuration.
5
The controller reports “Charge
Fail” alarm.
•
To check if the controller's charging alternator terminal
is working or not:
I. Disconnect the charging alternator wiring to the
controller's terminal # 7.
II. Short the terminal # 7 to the ground through a DC
ammeter.
III. Crank-start the engine. The DC ammeter should
indicate the current in the range 200 - 400 mA for
~30 seconds.
IV. If yes, the controller's charging alternator terminal is
working OK.
•
Disconnect and re-connect the charging alternator and
connection to the controller's terminal # 7.
•
Check if the charging alternator is working OK or not.
6
The controller issues
unnecessary “crank-start”
command immediately after
power on.
•
Ensure that the controller's output terminal is not
directly connected to the starter relay. The controller's
output should be given to an intermediate relay which
should in-turn power the starter relay. The controller
can get permanently damaged and will need to be
replaced if this precaution is not taken.
•
Check start-relay connection with the suitable
controller terminal.
•
Enter “configuration mode” in the controller and verify
the configuration for “START MODE” and the “START
