Safety
Intended use
The enabling switch is a manually operated control device, which can be used as an en-
abling device when automated production equipment is used in manual mode. Authorised
personnel can access the danger zone while movable guards are open, to monitor work-
flows or carry out setup or maintenance work.
Each person accessing the danger zone must be equipped with an enabling switch.
Only evaluation devices that monitor for shorts across contacts may be used. As evaluation
devices we recommend the devices described under

The enabling switch may
not
be used on its own to switch on a potentially hazardous con-
dition.
The enabling switch may
not
be used in place of other safety measures.
