Specifications – Installation and Operating Instructions
VPS2411 P1
Bulletin F-65
The dual inductive, 2-wire AC/DC Series VPS Valve
Position Sensor maintains VDI/VDE 3845 dimensions so
positioners can be easily mounted on top of the sensor and
target. The Model VPS2411 Sensor and Model P1 Target
mount easily and directly to actuators with ISO-NAMUR topworks (see picture below). Fully adjustable target in 2° increments, the sensor has two independent LED’s and bright
Flow Line indicator that provide local visual indication. All
electrical connections are made with the Model VIP82 4-pin
quick disconnect cable (6 ft. in length) for ease in installation.
Solid state components are fully embedded in an epoxy resin
to prevent condensation build-up and to protect against
vibration and shock. The rugged PBTP housing provides
excellent corrosion resistance and moisture protection.
Two VPS2411 and one P1 shown mounted with W.E.
Anderson pneumatic actuator and positioner.

INSTALLATION PROCEDURE:
1. Fasten the Series VPS to the actuator with the appropriate fasteners (M5, 10-24, 10-32). For Namur C actuators
you must first attach the Namur C bracket to the actuator.
2. Attach the coupling to the actuator shaft for Namur A &
C actuators only.
3. Attach the collar to the actuator shaft or coupling.
4. Install one stainless steel flat head screw (two if it is a
dual sensor installation) into each of the target rings and
plug the other holes with the plastic screws or plugs. Slide
the target rings over the collar and adjust as appropriate for
open and closed position. NOTE: Bottom target energizes
the red LED and the top target energizes the green LED.
5. Place the cover onto the top target being careful to align
for proper flow indication and secure with M6 x 16 fastener
for Namur B actuators or M6 x 25 fastener for Namur A & C
actuators.
