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:
These are often configurable but generally include the Emergency Stop Button and motor protection switches.
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. delcos 3100 wiring diagram
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. The wiring for a Delcos 3100 system typically
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
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. ensure all connections are tight.
Use a multimeter to verify the wiring between the sensor and the controller's analog input terminals.
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 "---", it typically indicates a break in the wiring or a failed transducer.
