6.1 General
Before starting installation, inspect the di-
gital positioner for any transit damages.
The PMV D20 positioner is installed with a
mounting kit (according to NAMUR
specification) to the left-hand actuator sup-
port rod.
Generally, the unit can be installed in any
mounting position. The stroke feed-back
is realized by a follower arm and stem
clamps.
The mounting of rod actuators (according
to NAMUR) is described in Figure 3.
For the two mounting possibilities of cast
yoke actuators (according to NAMUR, lEC
534 part 6) refer to Figure 5.
After installation, ensure all screw
connections are tightened correctly and
all moving parts are free from excessive
friction.
Tighten front cover screws to 0.65 Nm to
ensure IP rating.
6. Mounting and installation
6.2 Mounting of the PMV D20
positioner on a linear
pneumatic actuator
(NAMUR / IEC 534 part 6)
(See Figure 3)
The mounting of a rod actuator kit
(according to IEC 534 part 6) is described
in an example by using the following
equipment:
Valve: Standard globe valve or
equivalent
Actuator: Single-acting pneumatic
actuator
Positioner: PMV D20 with NAMUR
mounting kit.
Pre-assembly: Valve with actuator (valve
stroke is matched with the actuator
stroke).
