Delcos 3100 Wiring Diagram !exclusive! 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.

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. delcos 3100 wiring diagram

The Delcos 3100 is a sophisticated microprocessor-based controller primarily used for stationary rotary screw compressors, such as the CompAir L-Series. Understanding its wiring diagram is crucial for safe installation, troubleshooting, and integrating features like remote start/stop or master/slave configurations. Core Wiring Components B2 Sensor: Monitors final compression pressure

Specific wiring layouts can vary slightly between "FS" (Fixed Speed), "SR" (Switched Reluctance), and "RS" (Regulated Speed) versions. Always consult the Gardner Denver/CompAir technical documentation specific to your model's serial number.

If the display shows "FAULT SENSOR" or "---", it typically indicates a break in the wiring or a failed transducer.
