Converting A Pneumatic Positioner - Samson 4765 Mounting And Operating Instructions

5 Converting a pneumatic
positioner
The pneumatic positioner can be converted
to a Type 4763 Electropneumatic Positioner
using a corresponding conversion kit.
A conversion kit is required for each
Type 6109 or Type 6112 i/p converter
module (see Table 3), which contains the
printed circuit boards, the cable gland and
the mounting screws.
For the Type 4763 Electropneumatic
Positioner, refer to the Mounting and Oper-
ating Instructions EB 8359-2 EN.
1. Undo the connecting plate (6) and re-
move along with sealing element (7). Pull
off the hose (5).
2. Twist the connecting nipple (4) from the
housing.
Type 6109 i/p converter module:
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-
tom, in the opening of the printed circuit
board so that the restriction and the filter
(8) are situated on the right side above
the innermost of the two housing holes
(supply air) when the module (dashed
line in Fig. 14) 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 sealing ring.
