Instruction for Encoder Mounting
In order to mount the encoder (according to the type a servo- resp. face-mount flange) the Wire Draw
Mechanism contains the adapter as well as mounting accessory parts (screws, seal ring and mounting
wrench). A max. starting torque of 2,0 Ncm should not be exceeded.
The screws to fix the MRA are not included in the scope of delivery, because their length depends on
the application.

Mounting order:
1. Remove the servo flange adapter form casing flange by means of locking clamps.
2. Insert round ring in the adapter.
3. Insert the encoder in the adapter and fix it via attached mounting screws.
4. Place coupling on the encoder shaft. Distance
a
between coupling and the bottom edge
of adapter has to be taken from the above table and to be set accordingly.
!!! Attention !!!
Axial overstraining of driving shaft of the rope length transmitter may limit the function!
5. Bring coupling to contact and fix adapter via clamps.
Mounting has to be effected according to above illustration (wire outlet on top). When mounting this way
the wire cannot jump off the drum.
It is only allowed to turn driving shaft by manual draw of measuring wire.
Non-observance may reduce return pull of spring motor and
destroy the wire draw mechanism !
Maintenance
The Rope Length Transmitter is maintenance-free, while intended using. Depending on the application,
a complete reversal of 1 mill. can be reached. It depends on the use of the complete measuring range
or only parts of the measuring range. Further influence factors are the traversal speed, the acceleration
as well as environmental conditions.
The repair works should exclusively carried out by the manufacturer. An opening of the device leads to
expiring of the warranty claims.
