Copeland 943-0053-00 PerformanceAlert Diagnostic Module Single Phase Compressor

The Copeland 943-0053-00 PerformanceAlert™ Diagnostic Module is a compressor protection and fault-detection device specifically designed for single-phase Copeland scroll and reciprocating compressors. Purpose-built for commercial refrigeration applications, this module helps HVACR technicians quickly identify and respond to system faults before they result in costly compressor failure or unplanned downtime.

By continuously monitoring compressor operating data, the PerformanceAlert module detects adverse conditions and flashes coded alerts through its onboard LED indicator, guiding technicians directly to the root cause of a problem. When a severe fault condition is identified — such as high discharge temperature, locked rotor, or open circuit — the module takes protective action and shuts down the compressor to prevent permanent damage.

Key Features:

• Designed exclusively for single-phase scroll and reciprocating compressors (part number 943-0053-00; bulk pack: 543-0053-03)
• Detects electrical and system faults including high discharge temperature, locked rotor, short cycling, open circuit, and low voltage
• Automatic compressor shutdown upon detection of potentially damaging operating conditions
• Flashing ALERT LED communicates fault codes for fast, accurate diagnosis
• Includes an external/remote LED indicator for installations where the module LED is not directly visible
• Optional USB Communication Kit (943-0143-00) enables laptop connectivity for system history retrieval and advanced diagnostics
• Compatible with CPC rack controllers including E2 and Einstein via gateway board (943-3730-00)
• Modbus communication support for third-party controller integration

Ideal for supermarkets, walk-in coolers, walk-in freezers, and reach-in refrigeration units, the Copeland 943-0053-00 PerformanceAlert module is an essential tool for protecting compressor investments and reducing service callbacks.
