4. Setup and Installation
Before beginning installation, ensure all power sources are disconnected to prevent electrical shock. It is recommended that installation be performed by a qualified electrician.
4.1 Mounting the Receiver Unit
- Choose a suitable outdoor location for the receiver unit, ensuring it is within range of the devices to be controlled and the remote control. The IP56 rating allows for outdoor exposure.
- Secure the receiver unit to a flat, stable surface using appropriate screws through the mounting holes located at the corners of the casing.
- Attach the provided antenna to the designated connector on the receiver unit. Ensure it is securely fastened for optimal signal reception.
4.2 Wiring Connections
The RWS-211C/12V/N requires a 12V AC/DC operating voltage. Use the cable glands at the bottom of the unit for secure and waterproof cable entry.
- Power Supply: Connect a stable 12V AC/DC power supply to the designated terminals inside the receiver unit. Observe correct polarity if using DC.
- Device Connections: Connect the electrical devices (e.g., garage door opener, lamp, pump) to the respective output channels (K1, K2, K3, K4) within the receiver. Each channel can handle a load of up to 16 A / 250 V AC (4000 VA). Refer to the internal wiring diagram for specific terminal assignments.
- Ensure all connections are tight and properly insulated.
4.3 Pairing the Remote Control
The remote control typically comes pre-paired, but if re-pairing is necessary or if you are adding new remotes, follow the manufacturer's specific pairing procedure, which usually involves a button sequence on the receiver unit and the remote.
5. Operating Instructions
Once installed and powered, the zaMel RWS-211C/12V/N is ready for operation using the provided remote control.
- The remote control features four numbered buttons (1, 2, 3, 4), each corresponding to one of the four output channels (K1, K2, K3, K4) on the receiver unit.
- Pressing a button on the remote will toggle the state of the corresponding output channel on the receiver. For example, if channel K1 is connected to a lamp, pressing button '1' on the remote will turn the lamp ON, and pressing it again will turn it OFF.
- The indicator LEDs (K1-K4) on the receiver unit will illuminate when their respective channels are active.
- Ensure the remote control has fresh batteries for optimal performance.
6. Maintenance
The zaMel RWS-211C/12V/N is designed for durability and requires minimal maintenance.
- Cleaning: Periodically wipe the exterior of the receiver unit and remote control with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Connections: Occasionally check all wired connections to ensure they remain secure and free from corrosion, especially in outdoor environments.
- Battery Replacement: Replace the remote control battery when its range decreases or it becomes unresponsive. Refer to the remote's specific instructions for battery type and replacement procedure.
- Antenna: Ensure the antenna remains upright and unobstructed for best signal performance.
