D 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 DVC6200 SIS 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 DVC6200 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 yellow 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 DVC6200 SIS 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 yellow 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 yellow 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.
