Controller emergency stop
Check if emergency stop button works properly; Check whether the
starting battery's positive pole is connected to the emergency stop
input; Check whether the circuit is open.
Low oil pressure alarm after crank disconnect
Check the oil pressure sensor and its connections.
High water temp. alarm after crank disconnect
Check the temperature sensor and its connections.
Shutdown Alarm in running
Check the switch and its connections according to the information on
LCD; Check auxiliary input ports.
Fail to start
Check the fuel oil circuit and its connections; Check the starting
batteries; Check the speed sensor and its connections; Refer to the
engine manual.
