Delcos 3100 Wiring Diagram -

Delcos 3100 is a specialized controller used primarily in CompAir rotary screw air compressors. Its wiring diagram is the blueprint for how the "brain" of the machine communicates with the motor, sensors, and safety switches to ensure efficient compressed air production. Core Components of the Diagram The wiring typically splits into two main sections: Power Circuit (High Voltage): This section details the incoming three-phase power supply. It shows the connections to the main motor Crucially, it outlines the Star-Delta (Wye-Delta) starter

What is the Delcos 3100?

1. Power Connection (24V): Connect the transformer's 24V hot wire to terminal 24V (R) . Connect the common wire to 24V COM (C) .
2. Thermostat: Connect the heating wire (usually white) from the thermostat to terminal TH (W) .
3. Limit Circuit: If your furnace has a dedicated limit terminal (some 3100s do), wire the high-limit and rollout switches in series between the TH input and the internal circuit. Otherwise, ensure the limit string is in series with the R line.
4. Inducer Motor: Connect the inducer motor hot wire to IND and its neutral to the system neutral bus bar.
5. Gas Valve:
