If a relay is used, when the sequence controller is switched on the signal 'Release control-
ler / emergency stop' must have a delay of at least 1 second after switching on the
115/230V supply. When an emergency-Stop has been activated, the signal has to be acti-
vated with a delay of at least 4 seconds.
When using hardware-module 385521 A (Safe torque off, see 17.9 Hardware-Module), the
internal voltage of the AST11 has to be provided permanently at input 'Release controller /
emergency stop' (contact pins 21 and 23).
