Delcos 3100 Wiring Diagram -
If the display shows "FAULT SENSOR" or "---", it typically indicates a break in the wiring or a failed transducer.
The wiring for a Delcos 3100 system typically divides into power supply, sensor inputs, and control outputs. According to the Delcos 3100 User Manual , the following connections are standard: delcos 3100 wiring diagram
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. If the display shows "FAULT SENSOR" or "---",
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 Warning: Always disconnect power and wait at least
Used to trigger the main motor contactor, fan motor, and solenoid valves (load/unload). Advanced Integration & Communication
Vibrations in rotary compressors can loosen terminal screws over time; ensure all connections are tight.
Terminals are available for remote start/stop and "Remote Load" enabling, which overrides local keypad control when activated in the Control Menu . Troubleshooting Wiring Faults
