Operating Instructions
Read Head CEM-A-LE05H-S2
Setting adhesive force
To change the preset adhesive force, you will need
a programming adapter (oder no. 110 013).
Proceed as follows:
Remove cable from plug connector X1
f
Connect programming adapter to plug connector
f
X1
Connect the connection cable to the programming
f
adapter and switch on the operating voltage (UB).
The CEM is in programming mode and succes-
sively clocks through the adjustment ranges
(see table). This process repeats itself until the
operating voltage (UB) is switched off.

Flashing 1x
Flashing 2x
Flashing 3x
Wait until the sequence of flashes indicates the
f
correct adhesive force and remove the program-
ming adapter before the device changes to the
next sequence of flashes.
The corresponding adhesive force is saved and
is available the next time the device is put into
operation.

Maintenance and inspection
WARNING
Loss of the safety function because of damage
to the system.
In case of damage, the related safety component
f
must be replaced. The replacement of individual
parts in a safety component is not permitted.
Regular inspection of the following is necessary to
ensure trouble-free long-term operation:
Check the switching function
f
Check the secure fastening of the devices and
f
the connections
Check for soiling
f
Check for sealing of the plug connector on the
f
safety switch
Check for loose cable connections on the plug

Exclusion of liability and warranty
In case of failure to comply with the conditions for
correct use stated above, or if the safety instruc-
tions are not followed, or if any servicing is not
performed as required, liability will be excluded and
the warranty void.
