Alarm & safety
Situation
If the thermal sensor is
disconnected.
If the thermal sensor is
short-circuited.
If the condenser sensor A
is disconnected.
Sensor abnormality
If the condenser sensor A
is short circuited.
If the condenser sensor B
is disconnected.
If the condenser sensor B
is short-circuited.
If the ambient tem. sensor
is disconnected.
If the ambient tem. sensor
is short-circuited.

●When "disconnecting/short-circuit of the thermal sensor" and "condenser temp. abnormality" are
activated at the same time, safety operation of compressor OFF is prioritized.
(Ex.) When "disconnecting of the thermal sensor" and "condenser A temp. abnormality" are activated at
the same time;
Compressor A: OFF
Compressor B: Continuous running
●The self-diagnosis time of "cooling circuit abnormality" cannot be changed. Depending on the operating
environment and condition, self-diagnosis time may be shifted or this function may not perform.
