Variants
Variants can be supplied to special order, please ask for details.
Troubleshooting
The load will not switch on:
• The LUX adjuster is set too low and is inhibiting the switch.
• The moving body is not emitting more IR than the background.
(Person wearing insulating clothing in a warm environment)
• Person is too far from the PIR switch, see detection diagram.
• Person is moving unusually slowly (perhaps when testing).
Loading
PIR occupancy switch with 1-10V
‘Step Down’ illuminance
CESPLL10VDC CEFPLL10VDC IP66
CESPLL10VDC(IP66) can be used to control high frequency 1-10VDC
dimmable ballasts. The products can be surface mounted onto ceilings.
These PIR switches incorporate a passive infra-red quad sensor to
detect movement of a warm body within their detection zone (diagram
B), a photocell to monitor the ambient light level and a adjustment
spindle to select the level of ‘Step Down’ illuminance.
Upon detecting movement, the PIR will switch the 1-10V dimmable
ballast to 100% on via the Switched Line output if the room is darker
than the setting on the rst lux adjuster (LUX, diagram D). Upon
nonoccupation the 1-10V dimmable ballast will switch to a pre-set
lower light level (‘Step Down’ illuminance), variable from 10% to
100% in 9 steps.
There is also a time lag function for adjusting the time that must
elapse with no movement detected before the PIR switch will switch
to its lower ‘Step Down’ level. This time lag can be set via the TIME
adjuster to 10 seconds, 20s, 40s, 1 minute 15 seconds, 2m30s, 5m,
10m, 20m or 40 minutes (diagram D).
CESP LL10VDC (IP66) also incorporates a sensitivity adjuster, labelled
‘SENS’, to reduce the range and sensitivity of detection (diagram D).
CESPLL10VDC can be ceiling mounted on the square pattress box
(not supplied). CESPLL10VDC IP66 is weatherproof to an IP66 rating
and can be ceiling mounted on the square pattress box (PABO)
supplied (to maintain an IP66 rating a suitable cable gland would
have to be tted).
These PIR switches can control up to 20x 1-10V dimmable ballasts,
assuming each ballast has a constant current output of 1mA.

E. Controlling corridors and larger areas
For the control of larger areas and corridors it is advised that
CESPLL10VDC (or CEFPLL10VDC IP66) are used in conjuntion with
DANLERS standard ceiling mounted PIR occupancy switches such as
CEFLPIR or CESFPIR and a DANLERS slave relay (CESLBL).
