Note
The digital valve controller must be configured using the SStem/Roller selection on the menu of the appropriate setup device.
The DVC6005 HW2 base unit was designed to work with a 40 kOhm potentiometer for travel feedback. However,
there are linear potentiometers that are readily available with a rated resistance of 10 kOhm. Therefore, the feedback
connections terminal box of the DVC6005 HW2 contains an additional 30 kOhm fixed resistor that may be added to
the circuit. This brings the total resistance up to the required 40 kOhm.
1. Mount the external 10 kOhm potentiometer to the actuator such that the mid‐travel position of the potentiometer
(5 kOhm) corresponds to the mid‐travel position of the actuator. This will leave an equal amount of unused resistive
element on both ends of the travel, which is required by the digital valve controller to function properly.
2. On the base unit, remove the feedback connections terminal box cap.
3. If necessary, install conduit between the potentiometer and the base unit following applicable local and national
electrical codes. Route the 3‐conductor shielded cable between the two units (refer to figure 2‐4).

4. Connect one wire of the 3‐conductor shielded cable between the terminal labeled “30k

” on the base unit and one
end lead of the potentiometer.
5. Connect the second wire of the 3‐conductor shielded cable between the middle lead (wiper) of the 10 kOhm
potentiometer to Terminal 2 on the base unit.
6. Connect the third wire of the 3‐conductor shielded cable between Terminal 3 on the base unit and the other
end‐lead of the 10 kOhm potentiometer.
7. Connect the cable shield or drain wire to the ground screw in the feedback connections terminal box of the base
unit. Do not connect the shield or drain wire to the external potentiometer.
8. Replace and tighten the base unit cover.
