Operation
Replacing and transporting the battery
– Screw both rubber buffers fully into the
exterior of the control compartment (1). Do
not use flat washers.
– Insert the battery into the changing frame
and fasten it to the load-side wall.
– Slide in the battery frame.
If the locking mechanism makes contact
with the rubber buffers (1) once the lock is
engaged, no further adjustment is required.
However, if an air gap remains between these
rubber buffers and the battery, the gap must
be calculated, e.g. by sliding in metal strips.
• A measurement of 1.5 mm is added to the
measured distance, and suitable washers
must be fitted between the wall and the
rubber buffers (1) to match the size of the
gap that has been calculated.
• The battery frame should strike both pads
simultaneously. By using different washers
for the rubber pads, the angle can be
corrected slightly if necessary.
– Check that the lock works correctly and
whether it is possible to pull the release
lever by hand (refer to the chapter entitled
"Actuating the battery lock".
If the lock does not engage or if it is difficult to
pull the release lever, the washers must be
reduced or the height of the rubber pads must
be decreased.
If the lock does not engage, it may also be
necessary to increase the insertion distance of
the battery frame. This is achieved by placing
suitable washers beneath rubber buffers (2)
on the load side.
If the lock still does not function properly
despite all of these adjustment options, check
whether the correct reach cylinder has been
installed or whether the stops in the end
positions have been set correctly using the
reach travel measurement system.
Determine the average value when installing
replacement batteries. The battery trays are
different sizes to accommodate the different
sizes of replacement batteries. In each case,
the battery lock must be set to the largest tray.
