Over current clamping timeout
â–¶ How to fix
Check for short circuit between the phases in the AC cables or in the compressor motor terminals. If no short circuit, check for compressor stalling or high pressure operation. This check can be done by inspecting the refrigerant circuit for blockage or faulty valves.
What you'll see
No driver-visible symptom recorded.
System reaction
System enters error mode and switches OFF
Diagnostic depth
Detection
Peak current, higher than 80% of 72A (switch OFF current), for more than 1 second
Possible cause
Output current was close to the current limit for more than 1 second. It may happen during starting the compressor or because of a overload or because of a weak short circuit in the AC side.
