Delcos 3100 Wiring Diagram May 2026

Terminal connections for the primary voltage source. Warning: Always disconnect power and wait at least 12 minutes for capacitors to discharge before touching electrical components. Sensor Inputs (Analog): R2 Sensor: Measures the final compression temperature. B2 Sensor: Monitors final compression pressure. B1 Sensor: Tracks line/network pressure.

Used to trigger the main motor contactor, fan motor, and solenoid valves (load/unload). Advanced Integration & Communication delcos 3100 wiring diagram

Are you looking to wire a or are you troubleshooting a specific sensor fault code? Terminal connections for the primary voltage source

Wiring can be configured for master/slave operation , where one unit manages the cycling of additional compressors to optimize energy efficiency. B2 Sensor: Monitors final compression pressure

For facilities managing multiple units, the Delcos 3100 supports advanced networking via its RS485 communication port .

Vibrations in rotary compressors can loosen terminal screws over time; ensure all connections are tight.

The controller can act as a slave in a wider Building Management System (BMS) using Modbus-RTU, allowing for remote monitoring of pressure and temperature.
