The "CTRL32 / STOP button pressed" signal is not available with the connection box standard. The
signal has no error detection facility and must, therefore, not be used for safety-critical
applications.
Observe the following when connecting the signal "Present31 HT 10 inserted":
• Connect Pin 7 of the connection box to the digital input of the control
• Connection box standard: Pin 8 of the connection box remains not assigned
• Connection box advanced: +24 V must be supplied at Pin 8
