Delcos 3100 Wiring Diagram -

Engages during the initial soft-start phase.

The controller typically operates on a 24V AC or DC control voltage supplied by a step-down transformer inside the compressor’s electrical cabinet. Main control power input. Terminal N / 0V: Neutral or ground reference line. Digital Inputs (Control & Safety)

The wiring interface of the Delcos 3100 is split into specific sections to prevent high-voltage interference with sensitive sensor signals. Power Supply Terminals delcos 3100 wiring diagram

Every physical pin assignment on the Delcos 3100 must align exactly with its designated functional path to prevent firmware errors or component damage. Main Power & Safety Triggers Engages during the initial soft-start phase

Monitors internal pressure before the minimum pressure valve.

Delcos 3100 closes outputs for Main Contactor (K1) and Star Contactor (K2) simultaneously. Terminal N / 0V: Neutral or ground reference line

The controller requires a stable control voltage to power its internal circuitry and display.
