GEYA Din Rail Automatic Recloser Circuit Breaker GRD9L-R GYM9 1P - Instruction Manual

1. Product Overview

The GEYA GRD9L-R GYM9 1P Automatic Recloser Circuit Breaker is designed for automatic reset after an electrical fault, preventing prolonged outages in unattended sites. It integrates a miniature circuit breaker (MCB) with an auto-reclosing device, making it suitable for various applications including meter boxes, new energy circuit management, PV solar control boxes, smart electricity systems, smart homes, and new energy vehicle charging piles.

This device automatically recloses when the MCB trips unexpectedly, reducing manual maintenance costs and improving efficiency by timely fault clearance. It features built-in reclosing attempts and provides alarm signals through an auxiliary contact. A manual/automatic selector switch and mechanical/electronic double locking functions enhance safety and control. The shaft transmission mode ensures stable and reliable operation, with the work status indicated by an LED.

3. Installation and Wiring

Proper installation is crucial for the safe and effective operation of the GEYA Automatic Recloser. Please follow these guidelines carefully.

Installation Steps

1. **Cooperate with RCCB/MCB:** Attach the recloser device to the RCCB or MCB as shown in the diagram. Ensure a secure mechanical connection.
2. **Accessories Installing:** If using additional accessories, install them according to the provided diagram, ensuring proper alignment with the ARD (Automatic Reclosing Device) and MCB/RCCB.
3. **Closing Lock:** When checking the circuit, ensure the RCCB/MCB cannot close when the lock function is activated. This prevents accidental reclosing during maintenance.

Wiring Diagram

Connect the device according to the wiring diagram. Ensure all connections are tight and correct for the specified voltage (AC220V for GRD9L-R-AC models, or DC12V/DC24V-48V for GRD9L-R-DC models). The auxiliary output (AUX) provides a maximum of 100mA.

Example Application Wiring

This diagram illustrates a typical application where the recloser protects multiple loads and can trigger an alarm lamp upon tripping.

4. Operating Instructions

The GEYA Automatic Recloser offers different control modes. Ensure you select the correct mode for your application.

Control Mode Selection

• **AUTO Mode:** The auto-reclosing function is enabled. The device will attempt to reclose the circuit breaker automatically after a trip.
• **MANU Mode:** The auto-reclosing function is disabled. The MCB/RCCB can only be opened and closed manually. This mode is useful for maintenance or when automatic reclosing is not desired.

Indicator Lights (PWR)

• When powered on, the green indicator will flash for 2 seconds to allow the power supply to stabilize.
• The green indicator light will then stay on.
• If the MCB/RCCB fails to trip, the red indicator light will be on.
• During auto-reclosing delay, the red indicator light will flash.
• After the delay, if the device switches on automatically, the green light will be on.

Automatic Reclosing Logic (GRD9L-D)

The GRD9L-D model has an automatic closing function with a specific reclosing logic:

• **Power Delay (Tr):** 2 seconds.
• **Reclosing Attempts:** Up to 3 attempts.
• **Reclosing Interval Times:** 10s, 60s, 300s.
• **Resetting Closing Times:** No trip or manual reset within 15 minutes after successful closing.
• The device will attempt to reclose the circuit after a trip with increasing delays (10s, 60s, 300s). If all attempts fail within 15 minutes, the device will lock out.
• To manually clear the closing times, switch from AUTO to MANU mode.

5. Troubleshooting

If you encounter issues with your GEYA Automatic Recloser, refer to the following common problems and their solutions:

• Problem: Unable to close or open.
  • **Solution 1:** Confirm whether the power supply voltage is normal.
  • **Solution 2:** Confirm whether the working mode is set to AUTO mode.
  • **Solution 3:** Confirm the buckle of the electric operation mechanism with the MCB is correctly engaged.
  • **Solution 4:** Confirm if the green terminal is connected with wires.
• Problem: Trips immediately after closing.
  • **Solution 1:** Check the circuit to confirm whether there is an overload, short circuit, or leakage fault at the lower end of the MCB/RCCB.
  • **Solution 2:** Verify if the circuit breaker is damaged or if it has slipped from its position.

6. User Tips

Based on common user experiences, here are some tips for optimal use:

• Always ensure the device is in MANU mode during installation or maintenance to prevent unexpected reclosing.
• Regularly check the wiring connections for tightness and signs of wear to prevent intermittent faults.
• If the device frequently trips, investigate the underlying electrical issue rather than relying solely on the auto-reclose function to mask a persistent problem.
