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.

Type 6112 i/p converter module:

3. Place the i/p module on the plug of the

printed circuit board, and tighten the

side terminal screws.

4. Check whether the hose seals (10, 11)

are properly inserted on the bottom side.

When the module (dashed line in

Fig. 14) is installed, the seal with throttle

and sieve must be situated on the right

side above the innermost of the two

housing holes (supply air).

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.
