Solenoid Valve Health Monitoring
The following steps assume the use of a single‐acting actuator with a solenoid valve installed. The DVC6200 SIS digital
valve controller, with single‐acting, direct relay C, must be powered separately from the solenoid. The unused output
of the DVC6200 SIS must be connected between the solenoid and the actuator as described in the Installation section.
The relay configuration selection must be “special application” and ValveLink software must have the triggered profile
enabled.
1. When allowed by the Logic Solver, momentarily remove and then restore power to the solenoid (typically 100 to
200 milliseconds). This process should occur quickly enough that the valve assembly does not move when the
solenoid is de‐energized.
2. With ValveLink software, upload the diagnostic data from the triggered profile menu.
3. Examine the graph and observe that there was a change in the pressure reading downstream of the solenoid.
