5. Setup and Installation
The DHRE-1 receiver is designed for external installation and can be connected to various gate and barrier drive systems. Refer to the diagram below for terminal identification.
5.1 Wiring Connections
The internal circuit board of the DHRE-1 features terminals for power input and relay output. Ensure power is disconnected before making any connections.
- Power Input (DC IN): Connect the appropriate DC power supply to these terminals. Refer to your drive system's specifications for the required voltage.
- Relay Output (COM, NO, NC): These terminals provide a dry contact output to control your gate or barrier drive.
- COM (Common): The common terminal for the relay.
- NO (Normally Open): The contact is open when the relay is inactive and closes when activated by a remote control signal.
- NC (Normally Closed): The contact is closed when the relay is inactive and opens when activated by a remote control signal.
5.2 Mounting
Mount the receiver in a suitable location, preferably away from large metal objects that could interfere with the radio signal. Ensure the built-in antenna has an unobstructed path for optimal signal reception. The IP20 protection class means it is not protected against water, so it should be installed in a sheltered location or within an additional protective enclosure if exposed to the elements.
6. Operating Instructions
6.1 Remote Control Programming
The DHRE-1 receiver can store up to 1,000 DoorHan remote controls. The exact programming procedure may vary slightly depending on the specific DoorHan remote model. Generally, the process involves:
- Locate the "Learn" or "Program" button on the DHRE-1 receiver's circuit board.
- Press and release the "Learn" button. An indicator light (LED) on the receiver should illuminate or flash, indicating it is in programming mode.
- Within a few seconds, press the desired button on your DoorHan remote control that you wish to program.
- The indicator light on the receiver should change (e.g., flash rapidly, turn off, or change color) to confirm successful programming.
- Repeat the process for any additional remote controls.
- To exit programming mode, wait for the receiver to time out (usually after 10-30 seconds) or press the "Learn" button again.
Note: If you need to clear all programmed remotes, consult the specific instructions for your receiver model, as this often involves holding the "Learn" button for an extended period.
6.2 General Operation
Once remote controls are programmed, pressing a programmed button on the remote will activate the relay output of the DHRE-1 receiver. This activation will trigger the connected gate or barrier drive to perform its programmed function (e.g., open, close, stop).
7. Maintenance
- Cleaning: Periodically clean the exterior of the receiver with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Connections: Annually check all wiring connections to ensure they are secure and free from corrosion.
- Antenna: Ensure the antenna is not obstructed and remains in good condition for optimal signal reception.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Receiver does not respond to remote. | Remote not programmed; remote battery low; receiver not powered. | Program the remote (Section 6.1); replace remote battery; check power supply to receiver. |
| Poor signal reception or reduced range. | Obstructions; interference; antenna issue. | Relocate receiver for better line of sight; check for sources of interference; ensure antenna is intact. |
| Gate/barrier does not operate after receiver activation. | Incorrect wiring to drive; drive malfunction. | Verify wiring connections (Section 5.1); consult your gate/barrier drive manual for troubleshooting. |
| Indicator light not working. | No power; internal fault. | Check power supply; contact support if power is confirmed. |
9. User Tips
No specific user tips were available from reviews or Q&A for this product. General advice includes:
- For optimal range, ensure the receiver is mounted as high as possible and away from large metal structures.
- If experiencing interference, try to identify and mitigate sources of radio frequency noise in the vicinity.
