7. Connect the blue/yellow two-wire-set from the user
interface board to the remaining receiver on the
analog output board (Figure 27).
NOTE: On some boards both set of wires are
red/black but have different connectors - only one
set will be able to be plugged into the analog output
board.
8. Replace the main cover.
Retrofitting to a Logix Digital Positioner
(with Diagonal Window in the Main Cover)
As shown in Figure 28, the earlier model of the Logix
digital positioner has an oblong, diagonal window (as
opposed to a circular window in the newer model). To
retrofit an existing Logix digital positioner to 4-20 mA
analog output, use the following procedure:
1. Remove the main cover and the user interface
cover from the Logix unit (Figure 29).
2. Disconnect the ribbon cable that connects the con-
trol board from the collector board.
3. Remove the three screws holding the control board
in place. Discard two of the screws.
4. Remove the control board from the Logix unit
(Figure 30).
5. Disconnect the cable that goes from the user inter-
face board to the collector board.
6. Remove the three screws holding the user interface
board in place. Save these screws as well as the
O-ring that goes between the user interface board
and the housing (Figure 31).
7. Install the new user interface board with its two
connectors inserted into the cavity of the housing.
Make sure the O-ring is between the user interface
board and the housing (Figure 32).
8. Install the three screws to secure the user interface
into the housing. Tighten to hand-tight.
9. Feed the user interface two-wire-sets in the hous-
ing, placing the wires in the trough at the bottom of
the housing. Connect the red/black two-wire-set to
the collector board where the old user interface
wire-set was connected. Pull the new blue/yellow
feedback two-wire-set so that it is next to the
red/black two-wire-set on the collector board.
NOTE: With some boards both sets of wires are
red/black but have different connectors. The feed-
back wire-set will be connected later to the analog
output board.
10.Carefully replace the control board, ensuring that
the clear pressure hose found inside the Logix unit
is not pinched.
11.Place the analog output board on the lower portion
of the control board and secure with the two longer
screws provided. Secure the top of the control
board with the original shorter screw (Figure 33).
12.Connect the control board ribbon cable to the col-
lector board.
13.Unplug the orange/red/brown or brown/red/orange
wire set from the collector board.
14.Plug the orange/red/brown or brown/red/orange
wire set into the correct receiver in the analog out-
put board.
15.Plug the three-wire-set from the analog output
board into the receiver on the collector board that
previously held the orange / red / brown or brown /
red / orange three-wire-set.
16.Connect the blue/yellow two-wire-set from the user
interface board to the remaining receiver on the
analog output board. NOTE: With some boards,
both two-wire-sets are red/black but have different
connectors - only one set will be able to be plugged
into the analog output board. Complete the installa-
tion by placing the Quick-Cal sticker on the control
board can and the user interface sticker in the user
interface cover (Figures 14 and 15).
17.Replace the main cover and the user interface
cover.
