4.8.4 Setting the force measuring unit
Fig.114: Setting the force measuring unit
► Set the actuator of the force measuring
unit so that it is centered and parallel.
To do this, move the plate, which holds
the actuator in place, back and forth.
NOTICE!
Observe the position of the pins!
The actuator pins must be aligned
straight to the connection disk on both
sides.
.
Fig.115: Set the Z axis
► Use a spring-type dial gauge to press
the Z axis until the inner pins touch the
contact disk.
Target value when touching: 20N
► If not: use adjustment shims to adjust
the setting and repeat the measure-
ment.
► Fit the buffer on the return unit.
