Description
One or more temperature sensors or pressure detectors installed on circuit n are either in short-circuit, broken
or disconnected.
Sensor or detector involved Condition for occurrence of fault
Suction temperature sensor TASPn ≤ -40°C
Internal sensor on electronic expansion 1000 U ≤ RDETn ≤ 50 U
Low pressure detector BPn ≤ 0,5 bars
High pressure detector HPn ≤ 0,5 bars
Note : All these sensors and detectors are not necessarily present on the same machine.
Action
F Immediate halt of circuit n.
F The fault is displayed on the screen.
F The remote fault report is delayed for 6 minutes.
Resetting
Circuit n can only be restarted after manual resetting and correct reading of all detectors and sensors.
