VRW2 DYNAMIC PRESSURE- REGULATING FLANGED CONTROL VALVES

62-3116—01

3.

Wire the Terminal Strip according to the appropriate dia-

gram for your actuator. See Fig. 5.

4.

500 ohm resistors are supplied for 4-20mA to 2-10 Vdc 

conversions. Two 2.2Kohm resistors are supplied for dig-

ital/3-Point Floating control. In this mode the actuator is 

sensitive to induced electrical voltages from other 

sources. To prevent such interference, wire the 

2.2Kohm, 0.5W resistor between pins 4 and 1 and a sec-

ond 2.2Kohm, 0.5W resistor between pins 3 and 1.

Fig. 5. Wiring connections.

5.

The actuator is preset for an analog input signal, normally closed 

operation. If this is suitable for the application simply connect the 

wiring per diagram. Once the power has been connected the 

actuator will run a calibration program and then begin normal 

operation. If the signal requirement must be changed, proceed to 

instruction 6.

6.

Remove power and set all Programming Dip Switches to OFF by 

sliding DIP switch toggles away from edge of circuit board (in 

direction of arrows in Fig. 6–9).

7.

Apply power and within 10 seconds, press and release the Reset 

Button. The programming and indication LED should start blink-

ing.

8.

Turn Programming Dip Switch #1, #2, or #3 ON then OFF to 

select signal requirement.
