Mounting
N.B. If the positioner is installed in a
hazardous environment, it must be of a
type approved for this purpose.
The D3 positioner has an ISO F05
footprint, A. The holes are used to attach it
to the mounting bracket B, which is suitable
for most types of linear actuator.
The spindle adapter C can be changed to
suit the actuator in question.
Remove the existing adapter using two
screwdrivers. Check that the spring ring on
the positioner spindle is undamaged and fit
the new adapter.
It is important that the positioner’s spindle
and the arms, that transfer the actuator
movements, are correctly mounted. Any ten-
sion between these parts can cause incorrect
operation and abnormal wear.
