Reference Models: EGA-18 (Sliding Gate) and EGB-18A (Swing Gate)
Scope: This guide outlines the universal wiring logic and step-by-step procedures applicable to most controllers of this type. Always disconnect the power before wiring, and wiring should be performed by a certified electrician. Follow the silk-screen markings on the controller for terminal identification.

I. Preparation and Safety Guidelines

1. Power Off:
Always disconnect the main power supply before wiring to avoid electric shock or damage to the controller.

2. Tools and Materials:
Prepare compatible motor wires, power lines, remote controls, access control devices, or infrared peripherals in advance.

 · Motor wire recommendation: ≥1.5 mm² to ensure stable load capacity.

 · Verify terminal markings: Carefully identify power, motor, and peripheral terminals to avoid misconnection.

 · Grounding requirement: The controller casing and all metallic parts of the gate must be properly grounded to prevent leakage or equipment damage.

II. Core Terminal Wiring Overview

1. Power Circuit (General)

 · Power Terminals: Power, L/N, Vcc, etc., supply the controller and gate motor.

 · AC Mains Connection: Connect AC220V live and neutral wires to L/N terminals. Some models support 110V; always check the nameplate. Never reverse live 

    and neutral. It is recommended to install a residual current device (RCD) or dedicated circuit breaker.

 · Backup Battery: Connect DC12V backup battery to the Battery terminal. Polarity must be strictly observed. The battery provides power only during a mains          outage.

 · Common Terminal (Com): Serves as the power/signal common ground or neutral. On some models, it works with Vcc to supply 12V to peripherals.

2. Motor Drive Circuit (Sliding vs. Swing Gate Differences)

(1) Sliding Gate (EGA-18)

 · Terminals: Motor1, Motor2 (Main)

 · Single Motor Models: Connect the motor's common, open, and close wires to Motor1’s Common, Open, and Close terminals.

 · Dual Motor Models: Main motor connects to Motor2 (Main), secondary motor to Motor1. Ensure motor rotation matches the gate movement direction.

 · Direction Adjustment: If the gate opens/closes in the wrong direction, swap Open and Close terminals; the common wire does not need adjustment.

(2) Swing Gate (EGB-18A)

 · Terminals: Motor; dual-gate models may have Motor1 and Motor2 for left and right gates.

 · Single Gate: Connect motor wires to the corresponding terminals (Open, Close, Common).

 · Dual Gate: Left gate connects to Motor1, right gate to Motor2. Default operation: main gate opens first, then secondary gate. Sequence can be adjusted via        controller parameters.

 · Direction Adjustment:
       1.Single gate: swap Open/Close wires if rotation is reversed.
       2.Dual gate: if synchronization is wrong, swap Open/Close wires on one gate.

3. Signal and Peripheral Circuit (General)

III. Step-by-Step Wiring Procedure

1.Power Circuit:

 · Connect AC mains (L/N), then backup battery (if available).

 · Ensure firm connections but do not power on yet.

2.Motor Wiring:

 · Connect motor wires according to silk-screen markings.

 · Initially, test the relays without motor load. Confirm no short circuits before connecting motors.

3.Peripheral Wiring:

 · Connect infrared sensors, access control, manual buttons, antenna, etc.

 · Ensure signal terminals are connected correctly to the common terminal.

4.Power-On Testing and Adjustment:

 · Check LED or digital display. A beep indicates the controller has started successfully.

 · Test manual buttons, remote control, and access control signals to confirm open/close/stop functions.

 · Adjust gate direction, limit positions, and anti-pinch sensitivity to ensure smooth operation.

5.Final Securing:

 · Disconnect power, organize and insulate wiring, secure the controller and terminals to prevent loosening due to vibration.

IV. Common Faults and Troubleshooting

V. Additional Notes

 · Terminal markings may vary slightly across brands. Always refer to the device manual before wiring.
 · Test the controller function without motor load first. Then gradually test under motor load to avoid short circuits or equipment damage.
 · Regularly inspect terminals to prevent oxidation or loosening that could affect gate operation.
