Summary

Safety Instructions

Safety Icon Explanation

Explains the meaning of safety icons used in the bulletin, including DANGER, WARNING, and CAUTION.

Instructions Pertaining to Risk of Electrical Shock, Fire, or Injury to Persons

Details critical safety instructions for electrical shock, pressurized systems, burn hazards, and compressor handling.

Safety Statements

Lists essential statements regarding the intended use, qualification of personnel, and observance of codes for refrigerant compressors.

Introduction

Theory of Operation

Explains how digital capacity control works using internal unloading, blocked suction, and solenoid valves.

Nomenclature

Describes how Copeland Discus digital compressor model numbers are designated and structured.

Digital Performance

Discusses the variation in nominal power consumption relative to capacity output for digital compressors.

Operating Envelope

States that operating envelopes for digital compressors are identical to standard Discus compressor envelopes.

Control

Details how capacity modulation is achieved by energizing/de-energizing a solenoid valve, affecting compressor output.

Control Requirements with Copeland™ Digital Compressor Controller

Compressor Wiring

Explains the wiring requirements for the Digital Compressor Controller, including motor current sensing.

Control Requirements with CoreSense Diagnostics

Highlights compatibility with CoreSense Diagnostics, eliminating the need for a separate digital compressor controller.

Master Controller

Specifies system controller compatibility, recommending E2 v2.3 or higher for digital compressors.

Recommended Application Settings for the Modulation on Copeland Discus Digital Compressors

Provides guidelines for application settings, including modulation cycle time and minimum load/unload times.

Solenoid Valve/Gaskets

Stipulates the use of Emerson solenoid valves and special gaskets for warranty compliance and reliability.

Thermistor

Details the thermistor requirements and its resistance-temperature ratio curve characteristics.

Multiple Compressor Application
