1. Travel Sensor Is Factory Adjusted
The placement of the feedback arm on the travel sensor is factory adjusted and sealed with anti-tamper paint.
This setting has been tested for functionality successfully several times before the DVC6000 ships from the factory.
Do not assume this setting is wrong.
Check everything else first before disturbing the anti-tamper paint.

2. DVC6000 – Potentiometer Issues
Potentiometer Components

3. Vibration Induced Potentiometer Wear
Some control systems are not grounded
Valve Travels in Higher Resistance Area (80 – 90% travel)
Amplification of travel noise by velocity gain in the DVC tuning ( Reduce affect by changing to velocity gain of 0)

4. No Potentiometer Wear

5. ValveLink Graph with Potentiometer Wear-Thru

6. Profile Test
Requires PD Tier

7. PD Profile No problems
