Flowserve 4-75 User Manual
4-75 Position
Indicator
FCD WCAIM2070-00 (Part 06525)
1. Description
The 4-75 position indicator is designed to be used with and mounted
in the Series 75, 120 VAC actuator with many of its standard options
including the I-75 Interface Kit and the DFC17 controller. Its output
is suited for 4-20 mA DC meter with 0-100% scale (such as General
Electric Type GE185), which is not part of the package. If properly
calibrated, it indicates actuator shaft position from closed (0°, 0%)
to open (90°, 100%). It is combined with standard Potentiometer
Kit, which supplies information on shaft position. If feedback potentiometer is required for other functions such as remote resistance
indication, or with a DFC17 controller, a dual Potentiometer Kit
must be used. Each potentiometer can serve only one function. For
installation procedures and wiring of potentiometer, see Potentiometer Kit Instructions (WCAIM2067) or 75 Actuator instructions
(WCAIM2013) or DFC17 instructions (WCAIM2026). These instructions can be obtained from your local distributor/supplier or online
at www.flowserve.com.

2. Installation
(See Figure 1.)
NOTE: This instruction sheet shows standard installation and wiring
of a 4-75 Position Indicator only. For 25/30 75 actuator, mount
4-75 assembly on top of limit switch(es) using same procedure as
shown below.
Remove the two mounting screws from right limit switch(es), as
viewed from terminal strip. Place two spacers (4) (use two spacers
(3) for M1 or M2 option) between limit switch and mounting plate
(2), and fasten mounting plate in place with two longer flat head
screws (5). Locate insulator (8) on top of mounting plate. Using
three spacers (3) to separate circuit board (1) from mounting plate
(2) and insulator (8), mount circuit board using #4-40 x 3⁄8 round
head screws (6) and nuts (7). Check entire assembly and firmly
secure all screws.

3. Wiring
(See Figure 2.)
NOTES: All wiring to terminal strip should be inserted only to midpoint of terminal strip.
When there are multiple wires going to terminal 1, use the short
white wire included in kit. Connect it to terminal 1 and then
splice it to the other white wires (common) using the closed end
splice provided.
Internal Wiring
There is internal wiring between the actuator terminal strip, feedback
potentiometer, and position indicator PC board. The white wire
(common) from PC board is wired to terminal 1 on internal side; the
brown wire (hot) from PC board is wired to terminal 2 on internal
side. Connect feedback potentiometer wires to the 4-75 position
indicator board terminal block (green to terminal 3, white/black to
terminal 2, and purple to terminal 1).
Remove yellow wire from terminal 5 and brown wire from terminal
6, disconnect them from N.O. contacts of switches 1 and 2 and
discard them. Output signal from PC board red wire (+) is wired to
terminal 5 and black wire (-) is wired to terminal 6 on internal strip
of terminal strip.
External Wiring
External wiring is between actuator terminal strip and outside power
supply and various controls. Common wire of the power supply is
wired to terminal 1 and hot wire of the power supply to terminal 2.
The actuator motor windings are electrically powered through its
own individual external single pole, double throw switch (supplied
by customer); counterclockwise and/or “to open” wire is wired to
terminal 3; clockwise and/or “to close” wire is wired to terminal
4, as shown in wiring diagram for actuator. An outside position
indicator meter is wired with positive connection to terminal 5 and
negative connection to terminal 6.
NOTE: External switch not needed when position indicator is
used with DFC17 controller, as controller board will power
motor windings.
Securely tighten all terminal screws. Secure all wires neatly with the
cable ties (9). Keep wiring away from all rotating parts and ensure
wiring is not pinched when actuator cover is installed.
Grounding wires should be connected to green-colored grounding
screw (if present) on actuator base or to any base plate mounting
screw in actuator.
Figure 2—Wiring of 4-75 120 VAC Position Indicator
NOTE: Attach wiring diagram label, included with kit, on inside of
cover, or modify existing label for the 4-75 option by marking terminal 5 “+”, terminal 6 “-”, and adding “4-20 mA output.”
For actuator using a 4-75 Position Indicator with a DFC17 Controller, the red and black wires from the indicator board will have to be
spliced directly to the external positive and negative output (Meter)
wires, respectively.
NOTE: Prior to wiring, follow Position Indicator board output calibration instructions in Section 4.
