2.3.3 Positioner body installation
■ Positioner body installation
Using the special-purpose mounting bracket, attach the main unit of the positioner to
the 2B stanchion.
Note
Install the positioner body in a location where it will not be subjected to severe vibra-
tion. Also, for the integral type regulator, install it such that the drain of the regulator is
facing downward.
If it is not possible for the drain to face downward, use the regulator separately.

2.3.4 Cabling between valve travel detector and positioner body
When attaching cabling between the valve travel detector and the positioner body, take
into account the operation of the control valve, the operation of the equipment, the
safety of the workers, etc., and ensure that none of these is affected.
Note
Avoid construction methods and installation methods which place the weight of the
valve travel detector and positioner body directly on the cable.
If, due to the relative mounting positions, this cannot be avoided, consider taking mea-
sures such as securing the cable to a nearby post.
If the cable goes upward, in order to prevent rainwater from entering the cable, first run
it downward and then turn it upward.
Perform cabling in accordance with electrical equipment technical standards.
The cable between the remote type valve travel detector and the body of the device can
be cut to any desired length and then adjusted.
Cable length adjustment must be performed by trained service personnel from Azbil
Corporation, using special-purpose tools. If cable length adjustment is to be performed,
be sure to consult with Azbil Corporation.
