5 Mounting and start-up
To attach the positioner to valves with cast
yokes), mounting parts (order no. 1400-
5745) are used. For valves with rod-type
yokes (pillars), the mounting kit (order no.
1400-5745) and additionally the mounting
kit (order no. 1400-5342) are necessary
(see page10).
Since the positioner can be attached on ei-
ther side of the valve, the physical location
(left or right attachment) should be deter-
mined before actual attachment.
Î See Fig.5 to Fig.8 on page17.
5.1 Attachment to valve with
cast yoke
1. Fasten the plate (20) to the stem connec-
tor (22) of the valve using the screws
(21).
2. Unscrew the positioner cover and secure
the positioner to the valve yoke using the
fastening screw (15). Make sure that the
pin (2) is inserted through the wire strap
and, as a result, clamped against the
plate (20).
5.2 Attachment to valve with
rod-type yoke
1. Fasten the plate (20), off-centered, to the
travel indicator (24) of the plug stem (23)
using the screws (21).
2. Place both the support (28) and the
clamping plate (26) on the rod (27) and
lightly fasten. Move the support until both
the center of the plate (20) and the sup-
port (28) are aligned when the valve is
at half of the valve travel.
3. Fasten tight the support and the clamp-
ing plate.
4. Mount the positioner to the support using
the fastening screw (15). Make sure that
the pin (2) is inserted through the wire
strap and, as a result, clamped against
the plate (20).
5.3 Housing cover
After attaching the positioner, make sure that
the vent plug of the housing cover faces
downward when the valve is installed.
