The pneumatic positioner (3766-x...x.04
and higher) can be converted to form a
Type 3767 Electropneumatic Positioner.
Note: Conversion of explosion-protected
versions only on request.
Apart from the Type 6112 i/p Module (see

-
cluding screw gland, fastening screw,
clamps and cables must be ordered.
1. Remove the support with the terminal
case (if existing).
2. Unscrew the connecting plate (3) and re-
move the silicone hose (2). Remove the
guard plate (4) and pneumatic screw
gland (1).
3. Connect the connecting cable to the ter-
minal base and the i/p module (6). Lead
the blue cable to the minus side and the
red cable to the plus side. Fasten the ca-
bles with terminal screws.

properly inserted on the bottom section
of the i/p module. When the module is
installed (broken line in Fig. 16), the
sealing hose including restriction and fil

ter must be located on the right above
the inner of the two bore holes (supply).
5. Fasten the i/p module and terminal base
using two screws each.

ring.
