Carrier 32GB500362 SPM Compressor Protection Board — Core Functions:
1. Real-time Monitoring of Comprehensive Compressor Parameters (Core)
Precisely acquires key parameters such as three-phase current, voltage, winding temperature, discharge temperature, suction pressure, discharge pressure, oil level, and oil temperature. It monitors the compressor’s operating status in real-time, providing essential data support for the protection logic.
2. Multiple Safety Protection Mechanisms (Core)
Integrates protection functions against overcurrent, overload, phase loss/reverse phase, high/low voltage, excessive discharge temperature, excessive winding temperature, low oil level, high oil temperature, and liquid slugging. In the event of an anomaly, it immediately shuts down the compressor, logs the specific fault code, and triggers an LED alarm—thereby preventing severe damage such as motor burnout, piston seizure, or liquid slugging at the source.
3. Compressor Start/Stop and Load Control
Receives commands from the main control board to precisely manage compressor start/stop operations as well as loading/unloading cycles, specifically adapted for scroll compressors. Features soft-start control to minimize inrush current during startup, thereby extending the compressor’s service life. Dynamically matches the unit’s operational load to optimize energy efficiency.
4. Communication Interaction and Data Transmission
Establishes bi-directional communication with the unit’s main control board and touchscreen interface via RS485 or CCN bus. It uploads real-time operating parameters, fault codes, and equipment status data, while simultaneously receiving commands from the main control board to facilitate collaborative control, remote monitoring, and system commissioning.
5. Fault Diagnosis and Memory Storage
Features built-in self-diagnostic capabilities, historical fault logging, and LED status indication functions. Supports both local and remote fault querying, facilitating rapid problem localization and troubleshooting to effectively reduce maintenance costs.

Common Product Faults and Replacement Indicators
1. Compressor Fails to Start / Frequent Start-Stop Cycles: SPM board power supply failure, damaged sampling circuit, false triggering of the protection circuit, or communication interruption;
2. Compressor Reports Overcurrent / Overload / Phase Loss Protection: Abnormal current sampling, phase detection fault, or disordered protection logic;
3. Frequent Triggering of Discharge Overheat / Winding Overheat Protection: Temperature sampling fault, drift in protection thresholds, or poor heat dissipation;
4. Low Oil Level / High Oil Temperature Protection: Abnormal signal from the oil level/temperature sensor, or fault in the SPM board’s processing circuitry;
5. Communication Error (SPM Disconnection): Damaged RS485 communication chip, interface failure, or software program corruption.
