CARRIER 00PSG000469000A CEPL 130602-02-R CEBD 430602-07-RA

CARRIER 00PSG000469000A is a compressor protection control panel (CPCS) specially designed for industrial refrigeration/air conditioning system, which belongs to one of the core industrial control components of Carrier brand.

Core function

Multiple safety protection

Grounding current detection: By connecting up to four series-connected current loop coils (one coil for each compressor), the grounding current abnormality can be monitored in real time. If unbalanced current (such as short circuit) is detected, immediately cut off the main circuit and shut down all related compressors.

Overload and short circuit protection: the built-in relay can trigger the protection action in advance before the circuit breaker trips.

Automatic reset mechanism: after troubleshooting, the NC (normally closed) contact needs to be manually reset by the button on the board to resume operation.

System integration and control

Main-backplane linkage: feedback the status signal to the main backplane (MBB) through the large relay to realize centralized monitoring.

Compatibility: It is suitable for various compressor types (such as 30XAXQXW series of screw machine) and supports industrial refrigeration system.

Diagnosis and maintenance

Service test mode: automatically check the status of safety devices and generate feedback signals after power-on.

Fault location: Support step-by-step troubleshooting of coil or compressor grounding fault.

Application scenario

It is mainly used for large commercial/industrial refrigeration equipment (such as central air conditioner and refrigeration unit) to ensure the safe operation of compressor under overload, short circuit or grounding fault.

Technical characteristics

High reliability: industrial-grade component design is adopted to adapt to harsh environment.

Modular expansion: each board independently controls a single equipment unit.
