TEST AND ADJUSTMENT
A. LED Function
LED is mainly designed as the Indicator while sensor is working
normally. When moving object is across the detection zone, LU
101/105 HF Transmitter is triggered with LED ON for about 2 seconds
and then turn off
(See Fig. 30).
B. Walk Test
LU 101/105 HF automatically works when power turns on.
If necessary, you can use Walk Test to test and adjust the detection zone,
which helps to make it work properly.
Procedures of Walk Test:
1. Aim the Transmitter LU 101/105 HF across the desired detection zone.
2. Warm up the Transmitter for about 30 seconds.
3. Make sure whether Transmitter and the combined Receiver have been
set with the same channel.
4. Make sure LED of Transmitter LU 101/105 HF works normally.
5. Have someone walk across from outside to the detection zone until
LED turns on.
6. When Transmitter LU 101/105 HF is triggered at the first time, LED will
turn on for about 2 seconds, then turn off. The next test won’t start until
the LED is off for about 4 seconds from the last test.
7. Repeat step 6 to step 8 until the detection zone meets your require
ment.
