Cause
1) Room temperature thermistor is discon-
nected or short-circuited.
(Only if it is not used for control)
1) Inlet oil temperature thermistor is discon-
nected or short-circuited. (When it is not
used for control)
1) The discharge pipe temperature thermis-
tor is disconnected or short-circuited.
The system will be stopped to protect OIL-

1) The condenser temperature thermistor is
disconnected or short-circuited.
The system will be stopped to protect OIL-
CON by upgrading the state to an alarm
after operation for 150 hours.
1) The radiator fin temperature thermistor is
disconnected or short-circuited.
1) There is an obstacle near the air intake/
exhaust port.
2) Operation outside the high temperature
range.
1) The monitor temperature has exceeded
the preset temperature. (It does not mean
a fault of the Oil Cooling Unit.)
