Complete system terminal strip wiring

Complete system terminal strip wiring

Use this as the main tracing reference for dispenser signals, pump outputs, E-stop logic, and system terminal-strip routing.

DMEX control architecture

DMEX architecture diagram

Shows one DMEX module allocated per multi-product dispenser with connections to shutdown, cashier control, tank monitor, product select, and pump contactors.

LVDD electrical scheme

LVDD electrical scheme

Shows how LVDD breaks low-voltage circuitry and receives control power from the DMEX module for single-point disconnect of the dispenser.

LVDD wiring diagram

LVDD wiring diagram

Use when tracing card reader, video, data, ethernet, auxiliary, and communication paths through the LVDD.

Sanitized terminal strip drawing

Complete terminal strip wiring

Good first-stop reference for tracing system-level terminal-strip routing, dispenser signals, and output paths.

Sanitized fueling strip 1 drawing

Fueling strip architecture 1

Useful for understanding breakout-module logic, product-select paths, and pump-contactor signal flow.

Sanitized fueling strip 2 drawing

Fueling strip architecture 2

Companion view showing how the same control logic repeats across additional dispenser groups.
