Please note
If there is too much coupling play this may cause:
Ĉ noise due to knocking on the coupling
Ĉ increased wear on the coupling
Ĉ bad running behaviour
Ĉ bad positioning accuracy
Ĉ in some cases to faults in identification travel.
Make sure that the play of the coupling is as small as
possible.
Warning
Lateral loadings produce false measuring results and may
damage the measuring system.
·
Use an external guide for the mass load in order to
prevent lateral loads on the connecting rod of the
measuring system.
Tubing of the DNCM−...
When compressed air is applied to port 4 of the proportional
directional control valve, the slide must move in the direction
of the measuring system zero point (electrical connection of
the potentiometer). If compressed air is applied to port 2, the
slide must move away from the measuring system zero point.
