Installation procedure
1. Please read these notes carefully before commencing work. In case of
doubt please consult a qualified electrician.
2. POSITIONING: The CESPLL10VDC (IP66) 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 CESPLL10VDC(IP66) and the rest with switching PIRs
with Volt Free secondary output and Normally Closed, Logic Gold relay
contacts (CESFPIRVFNCLG) 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.
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 A 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 nonoccupation.
Fully anti-clockwise will allow the ballast to
switch to 10% on non-occupation.
