the emergency stop or bypass functions in the C 4000.
$ If you use a SICK switching amplifier, then you can also connect the teach-in key-ope-
rated switch to the switching amplifier. There is more information in the operating
instructions for the switching amplifier.
Ensure that only authorised persons have access to the teach-in key.
