4.6 Foreseeable Misuse of Enabling Switch
Foreseeable misuse means the not allowed fixing of the enabling switch in
the enabling position. The foreseeable misuse of the enabling switch must
be restricted. The following measures causing the stop of the machine in
the manual mode are recommended:
z
Inquiry of the enabling switch when turning on the machine/plant and
inquiry of the enabling switch when changing the operating mode from
automatic to manual (The enabling switch must not be in the enabling
position.).
z
The enabling switch 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 activity.
!
WARNUNG!
•
The enabling switch is only suitable as safety function if the operator
activating the enabling switch recognizes the dangerous situation in
time so that he can immediately take the necessary measures to avoid
such situations.
As additional measure reduced speed of the movement can be neces-
sary. The allowed speed must be determined by means of a risk as-
sessment.
•
The enabling switch is only used to enable commands for performing
dangerous movements. The commands themselves must be activated
by a separate operating element (key on handheld terminal).
•
Only the person who operates the enabling switch is allowed to work in
the dangerous area.
•
For further informations regarding the enabling switch please pay atten-
tion to chapter CE Conformity, Directives and Standards.
