6. MAINTENANCE AND TROUBLE-SHOOTING
Should problems arise with the light fi tting's operation, turn off the power for a few moments,
then recheck the operation. Check also that the lamps are fi xed securely in their lamp holders. If
this has no effect, change the lamps. Check also the securing of the wires to the terminal block.
Always switch off the power before changing lamps! If the lamp has been changed while the
power is on, switch off the power for at least 30 seconds after changing the lamp.
After an interruption in the power supply there will be a self-test. Detecting the fault, the PIR
sensor's red LED will fl ash alternately bright and dim.
If the PIR sencor fails to work though the power supply is on, switch off the power supply before
removing the PIR sensor from the light fi tting and sending it for replacement.
7. CLEANING
The lens should be cleaned when necessary using a damp cloth. Do not use cleaning agents
or solvents as these may damage the lens surface!

8. TECHNICAL SPECIFICATIONS

· Minimum mounting height 1.7 m.
· Features a Passive Infra Red sensor unit (PIR).
· Power supply 220 - 240 V, 50 / 60 Hz
· Detection area: horizontal 360°, vertical approx. 135°
· Switch off 3 - 30 min after movement ceases (TIME setting).
· Sensitivity (within detection range) SENS, illumination level LUX (1 lx - infi nity) and TIME
setting
· ...6D, .../...4E and.../...7E: LUX - position max (= infi nity).
· ...4E: electronic ballast , starting time 1 - 2 sec.
· ...6D: dimmable electronic ballast: illumination level approx. 10% when continuously
on. This rises to 100% when the PIR reacts to movement.
· Max. external load: 400VA fl uorescent lamps or 400W incandescent lamps.
· Operating modes: automatic operation in dusk, test mode and lux setting mode
N.B. The LUX setting is affected by the angle of the incident light, as also by
e.g. refl ection from the setter's clothing. The LUX level can be set between
1 lx - infi nity.
NB! In the luminaire models ...6D and .../... (=continually burning lamp)
hold the LUX - potentiometer to max - position (infi nity).
TIME The TIME potentiometer enables the length of time the light
remains on after the sensor's last reaction to movement to be ad-
justed. The horizontal arrow points to 3 minutes. The setting range is
3 min - 30 min.
