Configurable functions
4.1 Restart interlock
The machine’s dangerous state () is locked in the event of an invalid object in the pro-
tective field ( in Fig. 18) or in the event of an interruption in the light path ( in Fig. 19)
and is not re-enabled () until the operator actuates the reset button.
The reset button is often also called the “local enable button”. In these operating instruc-
tions the term reset button is used.
The restart interlock can be implemented in two different ways:
 With the internal restart interlock of the C4000:
The outputs of the C4000 are enabled after the connected control switch is operated.
 With the restart interlock of the machine controller:
The C4000 has no effect on the restart.
The possible combinations are shown in the following table:
Restart interlock of
the C 4000
