Product Usage Instructions

Setting up for Automatic Operation:

1. Set the Dusk control knob fully clockwise.
2. Set the Time control to the desired number of hours or dusk/dawn.
3. Slowly rotate the control anti-clockwise until the lamp illuminates when the ambient light level reaches the desired darkness level (at dusk).
4. Leave the control set at this point for automatic operation.

Troubleshooting:

The level of ambient light in the area may be too bright to
allow operation at the current DUSK setting.| During the hours of darkness, turn the Time Delay knob to
minimum and adjust the DUSK control slowly anti-clockwise until the
lamp illuminates. Refer to the previous section for more
details.
Adjustment needed for the level of ambient light required for
activation.| Adjust the setting anti-clockwise to lower the level of ambient
light required for activation.

2300W Dusk to Dawn Light Controller

Model: NSLDD1000 – White

General Information

These instructions should be read carefully and retained for further reference and maintenance.

Safety

• Before installation or maintenance, ensure the mains supply to the sensor is switched off and the circuit supply fuses are removed or the circuit breaker turned off.
• It is recommended that a qualified electrician is consulted or used for the installation of this sensor and install in accordance with the current IEE wiring and Building Regulations.
• Check that the total load on the circuit including when this sensor is fitted does not exceed the rating of the circuit cable, fuse or circuit breaker.

Technical Specifications

• 230V AC 50 Hz
• This PIR is of Class ll Construction and must not be earthed
• Maximum Switching Load: 2300W Halogen Lighting
• Operation:
  • 500W Fluorescent Lighting 80W LED Lighting Dusk – Dawn, Dusk to 2/4/8 hours OFF, (adjustable Dusk sensing)
• IP44 Rated suitable for restricted external applications
• CE Compliant
• EC Directives: Conforms to latest directives

Installation

• Ensure the mains supply is switched off and the circuit supply fuses are removed or the circuit breaker turned off.
• An isolating switch should be installed to enable the power to be switched ON & OFF for maintenance purposes.
• Open the unit by gently prying the “ears” on each side of the unit (See diagram “A”). This can be done without a tool, but if you prefer use a flat blade screwdriver, but be careful not to damage the clips. The front cover is hinged at the top and the front cover will swing open upwards.
• Mark the position of the fitting holes using the unit as a template. Drill out the mounting holes taking care to avoid any joists, electrical cables or water/gas pipes that may be hidden beneath the surface. Insert the rawl plugs into the holes.
• Pass the 230V 50Hz mains supply and load cables through the cable entry points on the unit, ensuring the grommet(s) is used to maintain the IP rating of the sensor.
• Fix the unit to the wall using the correct screws for the rawl plugs installed.
• Terminate the cables into the terminal block ensuring correct polarity is observed and that all bare conductors are sleeved (See section 5. Connection Diagram).
• Attach the supplied cable clamp ensuring not to overtighten.
• 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 A ‘Loop Terminal’ is provided should a 3 core cable be used, which is marked .

Testing

The adjustment knobs located on the side of the sensor head (see diagram “D”) are factory set to “Daylight Mode” i.e. LUX set to the ‘Sun’ symbol.

• The Dusk setting determines at which light level the NSLD1000 will turn its connected load “ON”. Turning this setting fully clockwise allows you to test the circuit during daylight.
• Connect the unit to the mains and switch power ON.
• After a short delay, the unit will switch ON. This is indicated by the red LED (See diagram “C”). Any attached lights will also illuminate.

Setting up for Automatic Operation

• The TIME control determines how long the lamp remains illuminated after activation. There are 4 designated “time on” settings 2, 4, 8 hours and dusk until dawn.
• The DUSK (LUX) control determines the level of darkness required for the unit to start operating. The setting is best achieved by the procedure below;

1. Set the Dusk control knob fully clockwise and the Time control to the required number of hours or dusk/dawn.
2. When the ambient light level reaches the level of darkness at which you wish the lamp to become operative (i.e. at dusk) SLOWLY rotate the control in an anti-clockwise direction until a point is reached where the lamp illuminates.
3. Leave the control set at this point.

• At this position the unit should become operative at approximately the same level of darkness each evening.
• Observe the operation of the unit. If the unit is starting to operate too early (i.e. when it is quite light) adjust the control slightly anti-clockwise. If the unit starts to operate too late (i.e. when it is very dark). Adjust the control slightly clockwise.
• Continue to adjust until the unit operates as desired.
