7.3.6
Foreseeable Misuse of the Enabling Switch
Impermissible fixing of the enabling switch in the enabling position by using
auxiliary means is considered as foreseeable misuse. Such foreseeable misuse
is to be prevented.
The following measures causing the stop of the machine in the manual mode
are recommended:
●
Inquiry of the enabling button when turning on the machine/plant and in‐
quiry of the enabling button when changing the operation mode from
automatic to manual (The enabling switch must not be in the enabling
position.)
●
The enabling button must be released within a defined period and pushed
into the enabling position again. The length of the period must be defined
according to the requirements of the activity.
Non-functioning enabling device can have le‐
thal consequences!
WARNING
●
The enabling switch is only suitable as safety function if the person acti‐
vating the enabling button recognizes the dangerous situation in time so
that he or she can immediately take the necessary measures to avoid such
situations.
●
As additional measure reduced speed of the movement can be necessary.
The allowed speed must be determined by means of a risk assessment.
●
The enabling button must not be used as only component for initiating
dangerous states. For initiating dangerous states a second, intentional
start command is necessary (button on the hand-held terminal).
●
Only the person who operates the enabling button is allowed to work in
the dangerous area.
●
