Instructions
These instructions provide information about Switch and Position Transmitters. They are for use by
personnel who are responsible for installation, operation and maintenance of Switch and Position
Transmitters.
Safety Messages
All safety messages in the instructions are flagged with an exclamation symbol and the word Caution,
Warning or Danger. These messages indicate procedures that must be followed exactly to avoid
equipment damage, personal injury or death. Safety label(s) on the product indicate hazards that can
cause equipment damage, personal injury or death. If a safety label becomes difficult to see or read, or
if a label has been removed, please contact DeZURIK for replacement label(s).
Personnel involved in the installation or maintenance of valves should be constantly
alert to potential emission of pipeline material and take appropriate safety precautions.
Always wear suitable protection when dealing with hazardous pipeline materials. Handle
valves, which have been removed from service with suitable protection for any potential
pipeline material in the valve.
Inspection

Description
This valve accessory provides electrical functions in response to the open, closed, and intermediate
positions of a 2-way valve or a 2-position 3-way valve. Electrical switching and variable current
functions are provided in selected combinations. The adjustable sensing devices are mechanically
linked to a valve, a valve actuator, or a positioner.
Components are located in a sealed and accessible aluminum enclosure, constructed to comply with
NEMA types 4, 4X, 7 and 9. The position of the valve is visibly displayed in two windows at 180°
viewing angles. Three basic options consisting of mechanical switches, proximity switches, and a
position transmitter are provided individually or in selected combinations. The three options are
described below.
Electrical Connections
Field wiring enters through ¾" and ½" NPT electrical connections to a prewired and labeled terminal
strip as described in the following sections. One ½" pipe plug is provided with the unit. If the ½"
connection is not used, install the pipe plug tightly in the connection. Do not use thread sealant.
Mechanical Switches
The two SPDT or four SPDT mechanical snap-acting switches each have a rating of:
Silver Contacts -10 Amps at 125/250 VAC, or 0.5 Amp at 125 VDC.
Gold Contacts - 1 Amp at 125 VAC, or 0.5 Amp at 30 VDC
With two SPDT switches, the top switch is factory set to trip as the valve reaches the closed or
clockwise position, and the bottom switch is factory set to trip as the valve reaches the open or counter-
clockwise position. The internal wiring from the switches to the terminal strip is shown in Figure 1.
With four SPDT switches, the top (first) switch is factory set to trip as the valve reaches the closed or
clockwise position, and the bottom (fourth) switch is factory set to trip as the valve reaches the open or
counterclockwise position. The second and third switches are not factory set, but may be set in the
field. The internal wiring from the switches to the terminal strip is shown in Figure 2.
Figure 1—Mechanical Switches

Mechanical Switches (Continued)
Each switch is actuated by a rotating cam. To adjust a top switch, push the top cam down, rotate it to
the desired position, and release the cam so it engages into the new position on the spline. To adjust a
bottom switch, repeat the process with the bottom cam, but lift the cam upwards to rotate it to the
desired position. Each cam may be further fine-tuned between spline positions by turning the set screw
on the cam with a 1/16" hex driver. The set screw is limited to adjustment of no more than one full turn.
Proximity Switches
The two SPDT proximity switches each has a rating of 0.3 amp at 120 VAC, or 0.2 amp at 30 VDC. The
switch contacts are sealed for low-energy switching of solid-state signal circuits.
The top switch is factory set to trip as the valve reaches the closed or clockwise position, and the
bottom switch is factory set to trip as the valve reaches the open or counterclockwise position. The
internal wiring from the switches to the terminal strip is shown in Figure 2.
Each switch is actuated as the white stripe on its rotating cam aligns with the white stripe on the switch.
To adjust the top switch, push the top cam down, rotate it to the desired position, and release the cam
so it slides into the new position on the spline. To adjust the bottom switch, repeat the process with the
bottom cam, but lift the cam upwards to rotate it to the desired position.

Position Transmitter
The position transmitter provides a 4 to 20 mA output signal with the plus and minus terminals
connected in series with an external 24 VDC power supply. Voltage variations from 10 VDC to 40 VDC
do not affect the current signal. The maximum load is 700 ohms at 24 VDC. The unit is calibrated as
shown in the following steps. Refer to Figure 3 for component identification.
1. Plug the 3-pin potentiometer connector into the appropriate 3 pins on the 5-pin block as
described in Figure 3. The 5-pin block is located next to the span adjustment.
2. Place the valve in the position desired for 4 mA output. Do not connect power until step 4. If the
valve is in the closed or clockwise position, connect an ohmmeter to terminals 2 and 3 of the
potentiometer; if the valve is in the open or counterclockwise position, connect an ohmmeter to
terminals 1 and 2 of the potentiometer.
3. Loosen the coupling that drives the potentiometer shaft, and rotate the potentiometer so that the
ohmmeter reads 500 ± 100 ohms. Then tighten the coupling, and disconnect the ohmmeter from
the potentiometer.
4. Connect a 20 mA ammeter and a 24 VDC power supply to terminals + and –as shown in Figure
3.
5. Adjust the zero trimpot so that the ammeter reads 4 ± 0.1 mA.
6. Place the valve in the position desired for 20 mA output. Adjust the span trimpot so that the
ammeter reads 20 ± 0.1 mA. The zero and span adjustments are not interactive.

Indicator Adjustment
The open-closed indicator on all units, shown in Figure 4 as indicator drum (A4), may be re-indexed on
the input shaft as follows:
1. Remove the two mounting screws and washers near the conduit connection, and lift the unit
from position so that the bottom of the unit is accessible.
2. Loosen the screw (A5) about 3 turns.
3. Pull out the spacer (A6) and shaft adaptor (A1) so that the spacer pins are disengaged from the
timing holes in the indicator drum (A4). (The shaft adaptor may be a different size and/or shape
than shown in Figure 3.)
4. Rotate the indicator drum (A4) to the desired position, and push the shaft adaptor (A1) and
spacer (A6) towards the indicator drum (A4) to engage the spacer pins with the nearest timing
holes in the indicator drum. Tighten the screw (A5) to 8 ± 2 inch pounds.
5. Replace the unit in the same mounting position with the two screws and washers, and tighten
the screws to 80 ± 5 inch pounds.
6. To fine-tune the position of the indicator cover (A3), loosen the set screw (A2), and rotate the
indicator cover to the desired position. Tighten the set screw.
