The EMERGENCY STOP button is monitored using a safety relay K1
(3TK2805). When the EMERGENCY STOP button is pressed, safety relay K1
drops out immediately and opens the NO contacts that are included in the
connection between terminal 9 and terminal 64 on the infeed/regenerative
feedback module and in the supply path for delay module 3TK29.
As soon as the selected delay time has elapsed, delay module K2 (3TK29.3)
also drops out and opens the NO contacts that are included in the connection
between terminal 9 and terminals 48/63 and in the connection between terminal
NS1 and terminal NS2. EMERGENCY STOP can only be acknowledged when
the line contactor in the infeed/regenerative feedback module and the delay
module K2 have dropped out.
