With the “Temperature Sensor Open Circuit Alarm”
disabled there is a risk of a temperature sensor fault
going undetected. During this temporary period when
“Temperature Sensor Open Circuit Alarm” is disabled
it is important to regularly check the engine
temperature display and coolant level on machine. If
the display is reading “xxxx” or “----” when engine is
running hot- it is recommended to stop the machine
and investigate Temperature Sensor and associated
connections. It is also recommended to check coolant
level more regularly during this temporary period until
a final solution has been released by DOOSAN
Portable Power.
