Operation Verification
Before connecting the LCP200 to the process, conduct the following tests on the LCP200 connected to the
DVC6200 SIS.
Successful Partial Stroke Test
1. Verify that the Top (Green/Normal) light is on solid.
2. Press the Bottom (Test) pushbutton for more than 3 seconds (but less than 10 seconds).
3. Observe that the top light starts flashing when the valve starts moving.
4. Observe that the valve moves no more than the configured partial stroke test travel limit.
5. Observe that the valve returns to the normal operating position and the top light comes on solid.
6. If the relay contacts are being used, verify that the Test contact changes state when the PST is in progress. When
the PST is complete verify that the contact returns to the pre-PST state.
Manually Aborted Partial Stroke Test
1. Verify that the Top (Green/Normal) light is on solid.
2. Press the Bottom (Test) pushbutton for more than 3 seconds (but less than 10 seconds).
3. Observe that the top light starts flashing when the valve starts moving.
4. Before the valve reaches the travel limit of the configured partial stroke test, press the Top (Reset) pushbutton or
the bottom pushbutton.
5. Observe that the valve immediately returns to the normal operating position and the top light comes on solid and if
the contact is being used, the Reset contact changes state for 1.5 to 3 seconds.
6. If the relay contacts are being used, verify that the Test contact changes state when the PST is in progress.
Emergency Demand through the Logic Solver
1. Reduce the current to the DVC6200 SIS to 4 mA (for de‐energize to trip operation).
Note
For a loop powered installation, a minimum current of 8 mA is required at the trip state / “Safety Demand” for proper functioning
of the pushbuttons and lights.
2. Observe that the valve moves to its Trip state.
3. Observe that the Middle (Red/Trip) light comes on solid and the Bottom (Yellow/Ready-to-Reset) light stays off.
4. Increase the current to the DVC6200 SIS to 20 mA (for de‐energize to trip) and observe that the valve behaves as
5. Observe that the middle light stays on solid and the bottom light comes on solid (ready to reset).
6. Press the Top (Reset) pushbutton.
7. Observe that the middle and bottom lights go off, the valve moves to its normal operating position, and then the
Top (Green/Normal) light comes on solid.
8. If the relay contacts are being used, verify that the Reset contact changes state for 1.5 to 3 seconds when the top
pushbutton is pressed.
