Installation procedure
1. Please read these notes carefully before commencing work.
In case of doubt please consult a qualified electrician.
2. POSITIONING: The CESF PIR IP66 should be installed to achieve
correct coverage of the area, see diagram A. If the photocell override
facility is required, the switch must be located above an area where
daylight can give greater illumination than the artificial light. Avoid
locating this product where it is exposed to windy or drafty conditions
(exposed lobbies, open ceiling voids or near ventilation fans) or
near heat sources. To cover large areas CESF PIR IP66s should
be spaced in a 5 metre grid formation.
3. The greatest energy savings will be made if each CESF PIR IP66
controls an independent set of lamps. They can be wired in parallel
but this should ideally be limited to three, see diagram D.
4. Make sure the power is isolated from the circuit. The CESF PIR
IP66 should be connected as shown in diagrams C & D:
L - Live in. N - Neutral in. SL - Switched Line out.
Start-up mode
When the CESF PIR IP66 is powered up, it will switch on the load
for 1 minute, the load will then switch off and the CESF PIR IP66 will
enter its Operating Mode. If a manual override-off switch is positioned
before the CESF PIR IP66 in the circuit (diagrams C & D, note 1) it
will do this each time the wall switch is switched on. Alternatively, if
the wall switch is placed after the PIR (diagrams C & D, note 2) it will
not enter the start-up mode each time.
Time and Lux set-up
For convenience, ensure that the TIME is set to the minimum when
setting up the LUX level. Afterwards set the TIME to a value suitable
for the application, making reference to diagram B.
The LUX is best set up when the local ambient light is at approximately
the minimum desired working light level, a lux meter placed on the surface
under the CESF PIR IP66 may help. With the LUX set fully clockwise
wait for the CESF PIR IP66 to switch off. Rotate the LUX adjuster
slowly anticlockwise (- to +), whilst waving your hand approximately
1m below the PIR, until the load switches on.
