6.8 Teach-in key-operated switch
Instead of the teach-in key-operated switch a comparable tamper-proof device, e.g. an
MMI (Man-Machine-Interface) with password protection can be connected.
For teach-in a reset button must be connected to the C4000 (see chapter 6.7 “Reset
button” on page 58).
If you connect a teach-in key-operated switch to the C4000, then you can no longer use
the emergency stop function or the bypass function in the C4000.
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.
On a cascaded system with a C4000 Guest or a C4000 without extension connection as
the last guest, you can only connect the teach-in key-operated switch to a switching
amplifier.
Ensure that only authorised persons have access to the teach-in key.
