TROUBLESHOOTING

Problem: Lamps do not switch on.

Solution:

Check the LINE and LOAD wiring connections to the unit and ensure the mains supply is switched on.

The ambient temperature may have exceeded the set point temperature. If necessary, increase the set point

temperature (VR1).

Check the lamps/Lamp fittings.

Contact your supplier.

Problem: Lamps do not switch off.

Solution:

Ensure nobody enters the detection area for 5 minutes. This will allow the 5 minute on-time to expire.

The PIR might be continually being re-triggered due to false activations. Mask the PIR lens and wait 5 minutes. If

the lamps switch off after 5 minutes, the PIR is receiving false activations. See section ‘Installation’.

Contact your supplier.
