B. Indicator (LED) Function
LED is mainly designed as the indicator of Walk Test.
When environment is applicable for LUX, trigger the transmitter LU
102/180 HF, LED of LU 102/180 HF turns on for about 5 seconds and
turns off then. At the same time, the load controlled by LU 102/180 HF
turns on and turns off too. The load's light-up time is decided by the time
set of the Transmitter LU 102/180 HF. After time set reaches, LU 102/180
HF can be re-triggered and LED may light on for about 5 seconds and light
off. Before time set reaches, re-trigger the sensor, the combining receiver
is able to receive the signal and time set re-count then, but LED does not
light on again.
C. Walk Test
LU 102/180 HF automatically works when turns power on.
If it is necessary, you can use Walk Test to test and adjust the detection
coverage of Transmitter LU 102/180 HF, that helps to make it working as
you required. Before the test, adjust LUX to " ", Meter to "+", Time
to "_", then you can start Walk Test (See Fig. 18) .
