However, it stops immediately with
remote control stop signal.
However, it stops immediately with
remote control stop signal.
Overload Protector
• 2-Stage OLP to protect the compressor.
Overload Protector will trip when
– Temperature of compressor increases
– Temperature of compressor increases
to 120°C.
– High temperature or high current flows
to compressor.
