How to Understand and Use the Terminals on Your RITROX / LOCKMASTER Ga

Knowing the function of each terminal on the control board of your gate operator is essential to avoid confusion, prevent damage, and ensure a successful setup. This guide explains the key terminal functions using the RITROX / LOCKMASTER RXD365, EKD365, and EKD700 swing gate openers, specifically the EKPKMJ4B control board as an example.

📋 Terminal Overview

Terminal	Label	Description
1	+24	24VDC Output
2	PHOTO	Photocell Input
3	GND	Ground
4	O/S/C	Open/Stop/Close
5	COM	Common Terminal
6	OPSW	Open Switch
7	EDGE	Edge Sensor
8	GND	Ground
9–10	ADAPTER	AC/DC Adapter Input
11–12	+BAT-	Battery Input
13–14	-LOCK+	Electric Lock Output
15–16	MOTOR1	Motor 1 Connection
17	ULT1	Up Limit Switch 1
18	COM	Common Terminal
19	DLT1	Down Limit Switch 1
20–21	MOTOR2	Motor 2 Connection
22	ULT2	Up Limit Switch 2
23	COM	Common Terminal
24	DLT2	Down Limit Switch 2
25–26	+LAMP-	Alarm Light Output

Note: Terminals are typically used in pairs and not individually. Accessories often require multiple terminal connections.

🔌 Functional Descriptions

Terminals 1 (+24) & 3 (GND)

Function: Provides 24VDC output to power photocells or sensors.
Note: Output is only active when the motor is running. Compatible with third-party photocells.

Terminals 2 (PHOTO) & 3 (GND)

Function: Signal input from the photocell. Operates on Normally Closed (NC) contact.
Behavior: When the sensor is blocked, the gate stops or reverses. Compatible with third-party NC dry contact photocells.

Terminals 4 (O/S/C) & 5 (COM)

Function: Trigger gate operation (Open → Stop → Close) using Normally Open (NO) dry contact.
Usage: Connect wall switches, keypads, or external receivers.

Terminals 6 (OPSW) & 5 (COM)

Function: Trigger gate opening only. Typically used with a vehicle sensor or loop detector (NO dry contact).
Behavior: When a vehicle is detected, the gate opens. It does not close or stop.

Terminals 7 (EDGE) & 8 (GND)

Function: Input from an edge safety sensor (e.g., rubber safety edge).
Behavior: If the gate hits an obstacle, the signal opens and the gate retracts. Works on Normally Closed input.

Terminals 9–10 (ADAPTER)

Function: Input for a power adapter to charge the battery. Accepts 36VDC or 24VAC.

Terminals 11–12 (+BAT-)

Function: Main 24VDC power input from battery or DC power supply. Powers the entire system and accessories.
Note: Compatible with third-party 24VDC 180W adapters.

Terminals 13–14 (-LOCK+)

Function: Output for electric gate lock (24VDC for 4 seconds after gate begins to open).
Note: Supports locks with 24VDC, max 3A current.

Terminals 15–16 (MOTOR1) / 20–21 (MOTOR2)

Function: Connects to Motor 1 and Motor 2 (red and black wires).

Terminals 17 (ULT1), 18 (COM), 19 (DLT1) / 22 (ULT2), 23 (COM), 24 (DLT2)

Function: Inputs for limit switches:
- ULT (Up Limit): For near-limit position
- DLT (Down Limit): For far-limit position
Note: Use the green wire as common and connect it to the COM terminal.

Terminals 25–26 (+LAMP-)

Function: Output for flashing alarm light during gate operation.
Note: 24VDC, max 1A. Compatible with most 24VDC lights.

⚠️ Safety Tips

Always turn off the power before making any wiring adjustments.
Stay clear of the gate during configuration to avoid injury from unexpected movement.

✅ Conclusion

Each terminal on the EKPKMJ4B control board plays a vital role. By understanding their functions and wiring them correctly, you can maximize the performance, safety, and reliability of your RITROX / LOCKMASTER RXD365, EKD365, or EKD700 swing gate operator.
