7. Test ModeThe TSU 200 has an integrated test mode for checking the performance of UHFtransponders, and to automatically adapt the unit's antenna to local environmentalconditions. This simplifies alignment of the unit and its adaptation to specific localcircumstances of the application. The test mode can be activated with the test transponderTPU 3080T (Art. No. 1388.000) within 30 seconds after the unit is switched on. Afteractivation the antenna is first automatically adjusted. During this adjustment there must notbe any object directly in front of the antenna. Following this, for a period of five minutes,each transponder in the field will be signalled by the three LEDs and the beeper. Using thedeister test transponder, the specified reading distance in an installed system can bechecked at any time.Notification Status TSU 200Yellow LED on for 30 seconds after switching on Waiting for test transponderRed, green, yellow LED light sequence Test modeAll LEDs blink, beeper Transponder read in test modeZulassung_wi_en_ts_tsu-200_pro_v140205_te_bf 15
