SHUTDOWN ALARMS
When controller detects shutdown alarms, detailed alarms information will be displayed on LCD
alarm page.
NOTE:
When shutdown alarm inhibition enables, for No. 1~9, when shutdown alarms occur for controller, it only
displays shutdown alarm information, but not control ECU shutdown; if stop is needed please press stop button. No. 10
controls ECU shutdown; when shutdown alarm inhibition disables, shutdown alarms occur for controller, , it will control
ECU shutdown.

Type
Description
1 ECU Shutdown
When the controller received engine shutdown signals via J1939, it will
initiate a shutdown alarm signal and fault code and name will be
displayed.
2 ECU Comm. Failure
When the engine start up but controller didn’t via J1939 receive engine
shutdown signals, it will initiate a shutdown alarm signal.
3 Aux. Sensor 1~2 High
After sensors are enabled, when the controller detects that the sensor
value has exceeded the pre-set upper limit value, it will initiate a
shutdown alarm signal.
4 Aux. Sensor 1~2 Low
After sensors are enabled, when the controller detects that the sensor 1
value has fallen below the pre-set lower limit value, it will initiate a
shutdown alarm signal.
5
Aux. Sensor 3~4 High
Shutdown (current type)
After sensors are enabled, when controller detects sensor value is
above the pre-set upper shutdown value, it will initiate sensor high
shutdown alarm signal.
6
Aux. Sensor 3~4 Low
Shutdown (current type)
After sensors are enabled, when controller detects sensor value has
fallen below the pre-set lower shutdown value, it will initiate sensor low
shutdown alarm signal.
7 Input 1~5 Shutdown
When digital input port is configured as “shutdown” and after it is
active, it will initiate a shutdown alarm signal.
8
High Temp Shutdown
(ECU)
when controller detects the ECU temperature is above the pre-set upper
shutdown value, it will initiate high temperature shutdown alarm signal.
9 Low OP Shutdown (ECU)
when controller detects oil pressure has fallen below the pre-set lower
shutdown value, it will initiate low oil pressure shutdown alarm signal.
10 Emergency Stop
When it is active, starting output and ECU power output is
