Check that the power is switched ON at the circuit
breaker/internal wall switch. Turn OFF the power to
the unit and check the wiring connections as per the
diagram (See section 6. Connection Diagram).
Ensure no connections are loose. Check the lamp. If the
lamp has failed, replace. Ensure that the lamp is seated
correctly in the lamp holder. Please note that the unit
will not detect through glass (e.g. in a glazed porch).
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, adjust the DUSK control
slowly clockwise until the lamp illuminates.
Refer to previous section for more details.
Adjust the setting anti-clockwise to lower the level
of ambient light required for activation.
Unit may be poorly located (See section 4.
Selecting a Location) and re-locate the unit.
The PIR sensors are influenced by climatic conditions.
The colder the ambient temperature, the more effective
the sensor will be. You may need to make seasonal
adjustments to the sensor head position to ensure
trouble-free operation all year round.
