| 1. Set the desired blanking mode using the DIP switches (refer to the BLVT operating manual). 2. Install barriers in the protective field. These are blanked after programming. The first beam (as seen from the plug) must not be dark, as it is needed to synchronize the transmitter and receiver. If beam 1 is covered during teach-in, the light curtain assumes the error state and the orange and yellow LEDs on the receiver start to flash rapidly (about 4 times per second). The programming process must be repeated with a free first beam. 3. Turn the key switch to the programming setting. Wait until the controller's green LED indicates readiness for programming (about 2 seconds). If the green LED "Aktiv" is flashing, this indicates a wrong switching position of the DIP switches 4. Remove the key switch. Programming is complete once the green LED " is deactivated. On the Display of BLCT/ILCT appears about 2sec. the blanking mode (see also Table). 5. Test the protective field with an appropriate rod. At any point in the field, this rod must deactivate the outputs.
