User manual THEBEN LU 112

[. . . ] 2m from the floor to ensure effective functions. Measure the distance between the transmitter and the receiver before installation. Make sure transmitter LU 112/115 HF is mounted in effective working range. Avoid installing transmitter LU 112/115 HF on the thick wall or fence, which blocks transmission wave and shortens the remote controlling distance. [. . . ] LU 112/115 HF can be mounted on the wall (See Fig. Suggest not installing LU 112/115 HF in where the end zone is the main detected target To obtain excellent performance, please mount LU 112/115 HF horizontally on ceiling or the top of door-gate and vertically on wall, table or beside door-gate. Avoid Nuisance Triggering Transmitter LU 112/115 HF can be activated by any large animals, light reflective surfaces, heat sources or a moving object. Following guidelines will help you avoid nuisance triggering: Avoid the object moving directly toward the sensor that brings the less sensitivity of detection. Have the object move across the pattern zone that brings more sensitivity. Do not aim the sensor toward any kind of lighting sources. Avoid having the sensor toward the area or the object whose surfaces are highly reflective or are subject to rapid changing in temperature, such as the pool . Installation Procedure LU 112/115 HF can operate by using alkaline battery or connecting AC power by an AC adaptor. Please refer to the following for two methods of power supply: A) Please follow the steps below to insert new batteries: 1. The more activating frequencies and the lower environmental temperature is, the sooner of power consumption. In normal circumstances, alkaline battery for transmitter LU 112/115 HF can be used for about 6 months by triggering about 10 times every day at 20° C operating environment. The more adjustment from "_" to "+" will extend more distance for detecting zone from about 1m to 8m. Suggest setting knob to "+" when LU 112/115 HF is mounted on the ceiling or the top of doorgate. When environment is applicable for LUX, trigger the transmitter LU 112/115 HF, LED will turn on for about 5 seconds and then turn off. Walk Test LU 112/115 HF automatically works when power turns on. If it is necessary you can use walk test to test and adjust the detection coverage, which helps to make it work properly. Before the test, adjust LUX to " ", meter to "+", then you can start walk test. Aim the Transmitter LU 112/115 HF across the traffic pattern where you want to detect. Make sure the transmitter and the combined receiver have set with the same channel. Have someone walk across the pattern from outside of coverage until LED turns on. When Transmitter LU 112/115 HF is triggered at the first time, LED will turn on for about 2 sec. And send out the signal to receiver, then turn off. [. . . ] Repeat step 6 to step 8 until the detection coverage zone meets your requirement. Note: Whatever the meter knob to be adjusted at any position, the farthest of detection range can not be treated as normal detecting area. When Transmitter LU 112/115 HF fails to work normally, check assumptive problems and suggested solutions in following table that will hopefully solve your problem. Make sure the battery is enough and the batteries inserted correctly. [. . . ]
