4.2.2

Start input wiring

The Start input (terminal 16) works both in the operating mode "with start- and restart-
disable" and "without start- and restart-disable" in different ways:

• In the operating mode with start- and restart-disable, the TNT 35 expects two signal 

changes (push-button function) as switch-on signal. A failure in the 

 

start-/restart button, e.g. due to contact malfunction is safely detected by the TNT 35.
