Installation procedure
1. Please read these notes carefully before commencing work.
In case of doubt please consult a qualified electrician.
2. POSITIONING: The CEFPLL10VDC (SEAL) should be installed to achieve
correct coverage of the area, see diagram B. Avoid locating this product
where it is exposed to drafty conditions (exposed lobbies, open ceiling
voids or near fans) or near heat sources.
3. To cover larger areas and corridors PIRs should be spaced in a 5 metre
grid formation, with one CEFPLL10VDC(SEAL) and the rest with switching
PIRs with Volt Free secondary output and Normally Closed, Logic Gold relay
contacts (CEFLPIRVFNCLG) with all Switch Line outputs wired in series
(diagram E).
4. Make sure the power is isolated from the circuit.
The PIR should be connected as shown in diagram C:

Start-up mode
When the PIR is powered up, it will switch on the load for 1 minute, the load
will then switch off and the PIR will enter its Operating Mode. If a manual
override-off switch is positioned before the PIR in the circuit (diagram C,
note 1) it will do this each time the wall switch is switched on. Alternatively,
if the wall switch is placed after the PIR (diagram C, note 2) it will not enter
the start-up mode each time.
Time, Lux and ‘Step Down’ 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.
The LUX is best set up when the local ambient light is at approximately
the minimum desired working light level. With the LUX set fully clockwise
wait for the 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.
The single adjuster spindle on the back of the PIR is used to regulate the ‘Step
Down’ illuminance function lux level, see diagram E opposite. This must be
adjusted in situ so that the desired level of brightness is achieved under the
luminaire(s) being controlled. In areas where no natural daylight is present it
is advised that the LUX level is set to
͚
. inhibit off.

‘Step Down’ set-up
The STEP DOWN low light level range is adjusted
via the spindle on the top of the product and allows
the 1-10VDC ballast to switch from 10% to 100% in
9 steps. Fully clockwise will allow the ballast to switch
to 100% on non-occupation. Fully anti-clockwise will
allow the ballast to switch to 10% on non-occupation.
