Technical Information
Motion Detectors
DELTA reflex motion detectors, IP55
Commissioning
The first time the rated voltage is applied, or after each system
interruption of more than 3 s, the initialization phase of the motion
detector is restarted.
Initialization phase
When the initialization phase is started, the connected loads are
switched on for approx. 2 s. The red LED in the inside of the lens
flashes approx. 3 times a second for approx. 45 s until the
device automatically switches to test mode.
Test mode
Users can manually check the sensing range in this brightness-
independent mode with a switch-on time of 1 s and a delay time
of 2 s. During this check, it is possible to change the direction
and sensing angle of the lens. On expiry of the time span of
10 min set for test mode, the motion detector automatically
switches to the factory setting (brightness switching threshold:
7 lux / delay
time 2 min) or to the individual settings.
If you wish to reactivate test mode, this can be triggered by
simultaneously pressing the S1 and S2 pushbuttons for a mini-
mum of 3 s (max. 5 s). The LED flashes rapid
ly for 3 s and then
remains on. When the pushbuttons are released, test mode is
confirmed by the LED flashing twice. You can cancel test mode
by briefly pressing the S1 or S2 pushbutton. After a maximum of
10 min, the motion detector automatically reverts to the previ-
ously selected setting (factory setting or individual setting).
Sensing range
The sensing range can be changed by turning the lens +/- 30°
to the left or right.
If you need to limit the range, you need to cut out the supplied
transparent cover plate in accordance
with your required sens-
ing range.
The range can be changed by adjusting the swivel arm through
up to 120°.
Range of motion detector, IP55, 120°
Range/rear view monitoring of motion detector, IP55, 290°
Reset
Simultaneously press the S1 and S2 pushbuttons for a minimum
of 6 s. The motion detector is then reset to its factory setting
(brightness switching threshold: 7 lux/duty ratio: 2 min). This set-
ting is suitable for the majority of applications. Once the reset is
successfully com
pleted, this is confirmed by the red LED in the
lens flashing twice.
Individual setting
You can use the S1 and S2 pushbuttons to individually set the
brightness switching threshold and delay time.
Brightness-independent mode
In this operating mode, the load is switched on for the set delay
time at each movement, irrespective of the current brightness.
Brightness-dependent mode
In this operating mode, the load is only switched on for the set
delay time when it detects movement and if the brightness falls
below the current brightness switching threshold. If you require
a brightness switching threshold that differs from the factory set-
ting, you can store the current light conditions as the operating
point in the memory of the motion detector by pressing the S1
pushbutton for less than 3 s.
