Upgrading the pneumatic positioner

8 Upgrading the pneumatic
positioner
The pneumatic positioner can be converted
into a Type 4763 Electropneumatic Position-
er with a conversion kit.
Note:

The version suitable for oxygen of the
Type 4765 Pneumatic Positioner can-
not be converted to form a
Type 4763 Electropneumatic Position-
er.
Besides the required Type 6109 or
Type 6112 i/p module (see Fig. 13), the as-
sociated conversion kit (including printed cir-
cuit boards, cable gland and mounting
screws) must be ordered.
Note:

For details on the converted
Type 4763 Positioner, refer to Mount-
ing and Operating Instructions

move along with sealing element (7). Pull
off the hose (5).
2. Unscrew the connecting nipple (4) from
the housing.
3. Push the i/p module over the plug con-
nection onto the printed circuit board.
4. Insert the sealing element (7), on the bot-

20
above the innermost of the two housing
holes (supply air) when the module
(dashed line in Fig. 13) is installed.
5. Secure the module and the printed circuit
board in the housing (two screws for the
module, one screw for the printed circuit
board). Subsequently assemble the cable
gland (1) along with the seal.
With Type 6112:
1. Proceed as described in steps 1 and 2 of
Type 6109
2. Place the i/p module on the plug of the
printed circuit board, and tighten the

properly inserted on the bottom side.
When the module (dashed line in
Fig. 13) is installed, the seal with restric-
tion and filter must be situated on the
right side above the innermost of the two
housing holes (supply air).
4. Secure the module and the printed circuit
board in the housing (two screws for the
module, one screw for the printed circuit
board). Subsequently assemble the cable
gland (1) along with the seal.
