6.4. Configuration

6.4.1. Start configuration

External reset button (with edge detection)
• The external reset button is integrated as shown.
• The safety-monitoring module is activated by resetting (after
releasing) the reset button(= detection of the trailing edge).
• Faults in the reset button, e.g. welded contact or manipulations
which could lead to an inadvertent restart, are detected in this
configuration and will result in an inhibition of the operation.
Automatic start
• The automatic start is programmed by connecting the feedback
circuit to the terminals. If the feedback circuit is not required,
establish a bridge.
• Caution: Not admitted without additional measure due to the
risk of gaining access by stepping behind!
• Caution: within the meaning of EN IEC 60204-1 paragraph
9.2.5.4.2, the operating mode „automatic start" is only restrict-
edly admissible. In particular, any inadvertent restart of the
machine must be prevented by other suitable measures.
