6.7 Limit switch connection
Different limit switch systems can be used with the TST FUZ2 door controller. The default setting uses an
absolute encoder as the limit switch. In addition, mechanical cam limit switches may be used.
Compliance with the safety function in accordance with EN 12453:2017 requires the use of a position
encoder with PL "c", minimum cat. 2 in accordance with EN 13849-1.
6.7.1 Absolute encoder TST PE or TST PE FSB with WICAB system
Absolute encoder TST PE is a single turn encoder. The driving shaft must not execute more than a single
revolution over the entire path of the door.
Absolute encoder TST PE FSB is equipped with the WICAB radio system. The WICAB system can be
employed to replace the spiral cable with a wireless link. For this purpose, a mobile unit TST FSBM or TST
FSAM must be mounted on the door leaf.
