VRW2 DYNAMIC PRESSURE- REGULATING FLANGED CONTROL VALVES

62-3116—01

8

Programming Normally Open or Normally Closed Setting

The Actuator is delivered from the factory set to the “normally 

closed” function for an analog control signal so that a minimum 

signal of 2V or 4mA will close the valve and a maximum signal of 

10V or 20mA will open the valve to maximum flow.

Fig. 7. Actuator programming.

Programming Failsafe Open or Failsafe Closed Setting

This function applies to battery backup, failsafe models only that 

provide power storage to drive the actuator either open to the 

Maximum Flow Setting or fully closed in the event of a power supply 

failure.

Fig. 8. Failsafe programming.

Programming PWM Time Base Resolution Setting

This function applies only if the Actuator has been programmed to 

accept Pulse Width Modulation (PWM) signal.

Programming Actuator Zero and Span Adjustment

1.

Remove power.

2.

Re-apply power to terminal 2 and within 10 seconds, press and 

hold the Reset Button until the indication LED blinks once.

3.

Release the Reset Button. The indication LED should remain illu-

minated.

4.

Apply the new zero voltage to terminal 3. (Any value between 0-7 

Vdc)

5.

Press and release the Reset Button to memorize this value. The 

LED should blink once as confirmation.

6.

Apply the new maximum voltage to terminal 3. (Any voltage 

between 3-10 Vdc and at least 3 Vdc greater than the zero value.)

7.

Press and release the Reset Button to memorize this value. The 

indication LED should blink once as confirmation and then cease 

to be illuminated. The Actuator will now operate with the new zero 

and span.

8.

If the LED provides 3 sequences of 4 blinks the zero and span 

program was unsuccessful. This may occur if the difference 

between zero and maximum voltage were not equal or greater 

than 3 Vdc.
