Connect a 24 VDC power supply to the solenoid
valve and a second 24 VDC power supply to the
DVC6000 SIS. Disconnect the solenoid valve
power supply, but maintain the power supply to
the DVC6000 SIS. The valve should go to its “fail
safe” position quickly. Then, maintain the power
supply to the solenoid valve and disconnect the
DVC6000 SIS power supply. The valve should go
to its “fail safe” position, although not as quickly as
it does in the previous scenario.
If DVC6000 SIS is alone, without a solenoid valve,
Disconnect power to the digital valve controller.
The valve should go to its “fail safe” position.
Note
The above tests are not applicable for
single-acting reverse relay B when no
solenoid valve is present.
If the LCP100 is used, conduct the following tests:
Successful Partial Stroke Test
1. Press the “Valve Test” (black) push button for
more than 3 seconds (but less than 10 seconds).
2. Observe that the green light starts flashing
when the valve starts moving.
3. Observe that the valve moves no more than
the configured PST travel limit.
4. Observe that the valve returns to the normal
operating position and the green light comes on
solid.
Manually Aborted Partial Stroke Test
1. Press the “Valve Test” (black) push button for
more than 3 seconds (but less than 10 seconds).
2. Observe that the green light starts flashing
when the valve starts moving.
3. Before the valve reaches the travel limit of the
configured partial stroke test, press the “Valve
Test” push button, or the push button next to the
green light.
4. Observe that the valve immediately returns to
the normal operating position and the green light
comes on solid.
Emergency Demand through the Logic Solver
1. Reduce the current to the DVC6000 to 4 mA
for de-energize to trip operation.
Note
You may remove the power
completely; however, the lights in
step 3 will be off. Without power to the
DVC6000 SIS, the LCP100 cannot
function.
2. Observe that the valve moves to its fail safe
state.
3. Observe that the red light comes on solid and
the amber light stays off (valve is not ready to
open).
4. Press the push button next to the green light
and observe that the valve does not move.
5. Increase the current to the DVC6000 to 20 mA
and observe that the valve remains in its fail safe
state.
6. Observe that the red light stays on solid and
the amber light comes on solid (ready to reset).
7. Press the push button next to the green light.
8. Observe that the green light starts flashing,
then becomes solid and the red light is off.
Emergency Demand through Local Control Panel
1. Press the push button next to the red light.
2. Observe that the valve moves to it fail safe
position.
3. Observe that the red light starts flashing, then
becomes solid and the amber light comes on solid
(ready to reset).
4. Press the push button next to the green light.
5. Observe that the red light goes off, the valve
moves to its normal operating position, and the
green light comes on solid.
Solenoid Valve Health Monitoring
The following steps assume the use of a single-acting
actuator with a solenoid valve installed. The DVC6000
SIS digital valve controller, with single-acting, direct
relay C, must be powered separately from the
solenoid. The unused output of the DVC6000 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.
