11. Troubleshooting
Problem
• Lamp stays ON
all the time
night and day.
Solution
The unit may be suffering from false activation.
Cover the sensor lens completely with a thick cloth.
This will prevent the sensor from “seeing” anything.
If the unit now switches off after the set time duration
and does not re-activate, this indicates that the
problem was caused by false activation. The problem
may be solved by slightly adjusting the direction/angle
of the sensor head (see previous section).
Check LED status:- If a single LED is constantly visible,
the unit is in Manual Override Mode and will illuminate
until dawn or until reset to Automatic Mode. To reset
to Automatic Mode, switch the internal switch/circuit
night the process will be repeated, the unit will remain on for this set period
(0 – 8 hours) and then will operate as a PIR unit until dawn.
• Switch the internal wall switch/circuit breaker 3 times (off/on off/on off/on)
within 2 seconds. A single flashing red LED at the top of the sensor head
indicates Holiday Mode.
• The unit will now illuminate for a user defined time between 1 and 8 hours.
The time can be set by rotating the centre adjustment knob as required.
(See diagram G, the adjustment knob is identified by the letter T inside a circle.)
• This time adjustment is factory set to 1 hour.
Note: Fully anti-clockwise is 1 hour, fully clockwise is 8 hours.
• After the defined period has elapsed, the unit will return to Automatic Mode
and operate as previously set up and the three scrolling LED’s will illuminate
from left to right.
• Holiday Mode will NOT reset to Automatic Mode at dawn, it will repeat each
night until reset by the user.
• To cancel Holiday Mode, switch the internal wall switch/circuit breaker once
(OFF/ON) within one second. The unit will turn to Automatic Mode indicated
by the scrolling LEDs.
