Instal·lació i cablejat
WARNING: Installation should only be performed by a qualified electrician. Ensure power is disconnected before installation to prevent electric shock.
Muntatge sobre carril DIN
The GRD9L-R is designed for DIN rail mounting (EN/IEC 60715).
Cooperation with RCCB/MCB
The GRD9L-R Auto Recloser is designed to cooperate with an RCCB (Residual Current Circuit Breaker) or MCB (Miniature Circuit Breaker).
- Cooperate with RCCB:
- Align the recloser with the RCCB.
- Connect the recloser to the RCCB using the provided accessories.
- Ensure a secure mechanical and electrical connection.
- Cooperate with MCB:
- Align the recloser with the MCB.
- Connect the recloser to the MCB using the provided accessories.
- Ensure a secure mechanical and electrical connection.
- Bloqueig de tancament: When checking the circuit, the RCCB/MCB cannot close when the lock function is activated. This prevents accidental reclosing during maintenance.
- Accessories Installing: The diagram shows how to install additional accessories (e.g., ARD) alongside the MCB/RCCB and recloser.
Esquema de cablejat
Connect the GRD9L-R according to the following diagram. Ensure correct polarity and voltage for the control circuit (A1, A2, COM, NO, NC, AUX) and the main power circuit (L, N, Load).
The wiring diagram illustrates a typical application where the GRD9L-R is connected to an RCCB, protecting multiple loads. An alarm lamp can be connected to the AUX contacts (COM, NO, NC) to indicate the status of the recloser or a persistent fault.
- L: Entrada de cable en directe
- N: Entrada de cable neutre
- A1, A2: Control power input (DC12V or AC220V depending on model)
- COM, NO, NC: Auxiliary contacts for alarm or remote indication.
- Càrregues: Devices protected by the RCCB/Recloser combination.
Instruccions de funcionament
Selecció del mode
The GRD9L-R features a selector switch for operating modes:
- Mode AUTOMÀTIC: 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 typically used for maintenance or when automatic reclosing is not desired.
Power Indicator (PWR LED)
- When powered on, the green indicator will flash for 2 seconds to wait for the power supply to stabilize.
- After stabilization, the green indicator light will 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 a successful reclose, the green light will be on.
Automatic Reclosing Logic (AUTO Mode)
The GRD9L-R attempts to reclose the circuit breaker up to 3 times after a trip, with specific time intervals. If reclosing is successful, the counter resets. If all 3 attempts fail within 15 minutes, the device will lock out and require manual intervention.
Reclosing Sequence:
- 1st Trip: If the MCB/RCCB trips, the recloser waits 10 seconds, then attempts to switch ON.
- 2nd Trip: If it trips again within 15 minutes, it waits 60 seconds, then attempts to switch ON.
- 3rd Trip: If it trips a third time within 15 minutes, it waits 300 seconds, then attempts to switch ON.
- Bloqueig: If the third attempt fails, or if there are continuous closing failures within 15 minutes, the device enters a locked-out state (LOCK) and will not attempt further reclosing until manually reset or the 15-minute timer expires after a successful reclose.
The closing times are reset if no trip occurs or if a manual reset is performed within 15 minutes after a successful closing.
Manteniment
The GEYA GRD9L-R Auto Recloser is designed for minimal maintenance. However, regular checks are recommended to ensure optimal performance and safety.
- Inspecció visual: Inspeccioneu periòdicament el dispositiu per detectar qualsevol signe de danys físics, decoloració o connexions soltes.
- Prova de funcionalitat: It is recommended to periodically test the RCCB/RCD functionality as per its own manual. The "Test Monthly" button on the RCCB/RCD should be pressed to ensure it trips correctly.
- Neteja: Keep the device free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquids or abrasive cleaners.
- Verificació professional: For any concerns or suspected malfunctions, consult a qualified electrician.
Always ensure power is disconnected before performing any inspection or cleaning.
Resolució de problemes
This section provides guidance on common issues you might encounter with the GRD9L-R Auto Recloser.
| Problema | Causa possible | Solució |
|---|---|---|
| Device does not reclose after a trip. |
|
|
| Red PWR LED is continuously ON. | MCB/RCCB failed to trip, indicating a potential issue with the circuit breaker itself or a very high fault current. | Immediately disconnect power and have a qualified electrician inspect the MCB/RCCB and the electrical system. |
| Red PWR LED is flashing. | Device is in an auto reclosing delay period. | This is normal operation. Wait for the reclosing attempt. If it fails, refer to "Device does not reclose" above. |
| Green PWR LED is OFF. | No power supply to the recloser. | Check the main power supply and the control power connections (A1-A2). |
| Closing lock prevents manual operation. | La funció de bloqueig està activada. | Deactivate the lock function as shown in the installation diagram (Figure 4). |
If the problem persists after attempting these solutions, contact a qualified electrician or the manufacturer for assistance.
Consells per a l'usuari
- Always ensure that the GRD9L-R is correctly paired with a compatible RCCB/MCB for optimal performance and safety.
- Regularly test your RCCB/RCD by pressing its test button to confirm it is functioning correctly. This ensures the entire protection system is reliable.
- For critical circuits where continuous power is paramount, consider understanding the reclosing delay times to anticipate power restoration.
- If frequent tripping occurs, it indicates an underlying electrical issue that needs to be addressed by a professional, rather than relying solely on the auto-reclose function.
