The Timeguard NSLDD1000 is a 2300W Dusk to Dawn light controller designed for external applications. This guide covers the essential installation, wiring, and configuration steps. Always ensure the mains supply is isolated before performing any work.
Safety
- Before installation or maintenance, ensure the mains supply is switched off and the circuit supply fuses are removed or the circuit breaker is turned off.
- It is recommended that a qualified electrician is consulted for installation in accordance with current IEE wiring and Building Regulations.
- Ensure the total load on the circuit does not exceed the rating of the circuit cable, fuse, or circuit breaker.
- This PIR is of Class II construction and must not be earthed.
Technical Specifications
- Voltage: 230V AC 50 Hz
- Maximum Switching Load: 2300W Halogen, 500W Fluorescent, 80W LED
- Operation: Dusk to Dawn, or Dusk to 2/4/8 hours OFF (adjustable)
- IP Rating: IP44 (suitable for restricted external applications)
Installation
- Ensure the mains supply is isolated.
- Install an isolating switch to enable power to be switched ON/OFF for maintenance.
- Open the unit by gently prying the "ears" on each side. The front cover is hinged at the top and swings upwards.
- Mark the position of the fitting holes using the unit as a template. Drill holes, taking care to avoid hidden cables or pipes, and insert rawl plugs.
- Pass the 230V 50Hz mains supply and load cables through the cable entry points, ensuring grommets are used to maintain the IP rating.
- Fix the unit to the wall using appropriate screws.
- Terminate the cables into the terminal block, ensuring correct polarity.
- Attach the supplied cable clamp without overtightening.
- Close the front cover.
Connection Diagram
Connect the cables to the terminal block as follows:
- 230V 50Hz Mains Supply IN: Live (Brown or Red) to L, Neutral (Blue or Black) to N.
- Load: Switch Live (Brown or Red) to L1, Neutral (Blue or Black) to N.
- Note: A 'Loop Terminal' is provided for 3-core cable use. N terminals are common.
Testing and Setup
The adjustment knobs are located on the side of the sensor head. They are factory set to "Daylight Mode" (LUX set to the 'Sun' symbol).
Setting up for Automatic Operation
- Set the Dusk control knob fully clockwise and the Time control to the required number of hours or dusk/dawn.
- When the ambient light reaches the desired darkness level, slowly rotate the control anti-clockwise until the lamp illuminates.
- Leave the control set at this point.
- If the unit operates too early (while still light), adjust the control slightly anti-clockwise. If it operates too late (when very dark), adjust slightly clockwise.
Troubleshooting
- Light sensor will not operate at night: The ambient light may be too bright for the current DUSK setting. Turn the Time Delay knob to minimum, then adjust the DUSK control slowly anti-clockwise until the lamp illuminates.
- Light activates during the day: Adjust the DUSK setting anti-clockwise to lower the level of ambient light required for activation.
