If the wiring diagram reveals no obvious faults in the CAN interface, fuses, or terminal connections, the next step is to contact an authorized service technician, as the issue may be a hardware fault within the control board or SR drive.
Can be wired for remote start/stop or remote load/unload functions. ⚠️ Critical Safety Precautions
A dedicated earth ground terminal must be connected to prevent signal noise and ensure operator safety. 2. Digital and Analog Inputs delcos 3100 wiring diagram
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
Always disconnect the system from the power supply before servicing the Delcos 3100. If the wiring diagram reveals no obvious faults
The wiring diagram is a critical technical document for the installation and troubleshooting of CompAir rotary screw compressors. It outlines the electrical architecture required to power the unit, connect control signals, and integrate safety features like emergency stops. Core Wiring Components
Monitors system pressure to regulate operation. The wiring diagram is a critical technical document
European wiring diagrams use an alphanumeric system (e.g., 1, 2, 3 or A1, A2). Tracing a wire by its exact number is easier than following it visually through a dense schematic. Component Abbreviations: -X... typically designates terminal blocks. -K... indicates relays or contactors. -M... indicates motors (e.g., Compressor Motor, Fan Motor). -B... indicates sensors and transducers. Common Troubleshooting Scenarios Using the Diagram
The Delcos 3100 controls the sequence of the star-delta contactors to manage motor startup current. Star Contactor
If you encounter incorrect readings after following the wiring diagram, the problem may lie in the calibration or the sensor itself. For example, if pressure readings are inconsistent (e.g., loading/unloading at the wrong intervals), technicians often check the or wiring continuity at the terminal strip.
