Function description
The switch is a 3-stage enabling switch:
} Not operated: no enabling signal (off)
} Operated as far as middle setting: enabling signal activated (on, enabling function)
} Operated as far as end stop: no enabling signal (off, panic function)
This guarantees that the enabling signal is interrupted not only when the switch is released
but also when it is fully operated.
If the enabling switch is fully operated as far as the end stop and then released, it will re-
main switched off during the changeover.
Wiring
When wiring, please note:
} Protect the cables from damage, by using a protective tube for example.
} Use shielded cables and connect the shield to the plant/machine's protective earth sys-
tem.
