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 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 PIRs should be spaced in a 5

metre grid formation.

3. The greatest energy savings will be made if each CESF PIR 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 should be connected as shown in diagrams C & D:

L - Live in.

N - Neutral in.

Start-up mode

When the CESF PIR is powered up, it will switch on the load for 1

minute, the load will then switch off and the CESF PIR will enter its

Operating Mode. If a manual override-off switch is positioned before

the CESF PIR 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 may help. With the LUX set fully clockwise

wait for the CESF PIR to switch off. Rotate the LUX adjuster slowly

anticlockwise (- to +), whilst waving your hand approximately 1m below

the PIR, until the load switches on.
