Action
DANGER
Turn off all:
• electric power supply
• hydraulic pressure supply
• air pressure supply
to the robot, before entering the safeguarded
space.
Check the position switch!
• Check that the rollers are easy to push in
and that they roll freely.
Check the rail!
• Check that the rail is firmly attached with
the attachment screws.
Check the cams!
• Check that the rollers have not caused
any impressions on the cams.
• Check that the cams are clean. Wipe them
if necessary!
• Check that the set screws holding the
cams in position are firmly attached.
Check the protection sheets on axis 1!
• Check that the three sheets are in position
and not damaged. Deformation can result
in rubbing against the cams!
• Check that the area inside of the sheets
is clean enough not to interfere with the
function of the position switch.
If any damage is detected, the position switch
must be replaced!
