Mounting the Follower Arm
1. Unscrew the lock nut for follower arm attachment.
2. Place the follower arm (12) on the shaft at the back
of the positioner (embossed scale facing the front)
and fasten it with the lock nut. The follower pin (15)
should point back from the positioner.
CAUTION: Maximum torque 0.18 ft-lbs (0.25 Nm)
Mounting the Stem Clamp Bracket and Take-off
Arm
1. Attach the stem clamp bracket (8) to the stem clamp
(7) and fasten it with two hexagon socket screws
(10) and lock washers (9).
2. Attach the take off arm (11) to the stem clamp
bracket
(8) and fasten it with a hexagon socket
capscrew (16) and a washer (17). Ensure the take-
off arm slot (11) is centered.
Mounting the Positioner
1. Adjust the actuator to mid-stroke.
2. Pre-assemble the mounting bracket (18) on the left
actuator leg (5) hand-tight with two U-bolts (6), nuts
(1) and lock washers’ (2).
The mounting of rod actuators (according to NAMUR)
is described in Figure 6.
For the two mounting possibilities of cast yoke actua-
tors (according to NAMUR, lEC 534 part 6) refer to Fig-
ure 4. After installation, ensure all screw connections
are tightened correctly and all moving parts are free
from excessive friction.
Valtek 2000, Kammer KA, Kammer KP, or standard
NAMUR linear valves use the same mounting kits.
Mounting of the Logix 500 Series
Positioner on a Linear Pneumatic
Actuator (NAMUR)
(Figure 6)
The mounting of a rod actuator kit (according to
NAMUR) is described in an example by using the fol-
lowing equipment:
Valve: Standard globe valve or equivalent
Actuator: Single-acting pneumatic actuator
Positioner: Logix 500 with NAMUR mounting kit
Pre-assembly: Valve with actuator (valve stroke is
matched with the actuator stroke)
For mounting, proceed as follows:
