DVC6000 Troubleshooting Checklist
1. Instrument serial number as read from nameplate ________________________________________________
2. Is the digital valve controller responding to the control signal? Yes _________ No _________
If not, describe ___________________________________________________________________________
3. Measure the voltage across the “Loop −” and Loop +” terminal box screws when the commanded current is
4.0 mA and 20.0 mA: __________V @ 4.0 mA __________V @ 20.0 mA.
(For a DVC6000 pwb built prior to 2003, these values should be around 9.4 V @ 4.0 mA. For a DVC6000 pwb
built after 2003, these values should be around 9.6 V @ 4.0 mA and 10.3 V @ 20 mA.
4. Is it possible to communicate via HART to the digital valve controller? Yes _________ No _________
5. What is the Diagnostic Tier of the digital valve controller? AC ____ HC ____ AD ____ PD ____ ODV____
6. What is the firmware version of the digital valve controller? ______________
7. What is the hardware version of the digital valve controller? ______________
8. Is the digital valve controller’s Instrument Mode “In Service”? Yes _________ No _________
9. Is the digital valve controller’s Control Mode set to “Analog”? Yes _________ No _________
10. Is it on Travel or Pressure control?
11. What are the following parameter readings?
Input Signal _________ Drive Signal _________%
Supply Pressure _________ Pressure A _________ Pressure B _________
Travel Target _________% Travel _________%
12. What are the following alert readings?
Fail alerts _______________________________________________________________________________
Valve alerts _____________________________________________________________________________
Operational status ________________________________________________________________________
Alert event record entries __________________________________________________________________
13. Export ValveLink data (if available) for the device (Status Monitor, Detailed Setup, etc.).
Mounting

2. What Make, Brand, Style, Size, etc. actuator is the DVC6000 mounted on? ________________________
3. What is the full travel of the valve? ____________________________________________________________
4. What is the Mounting Kit part number? _________________________________________________________
5. If mounting kits are made by LBP/Customer, please provide pictures of installation.
6. Is the Mounting kit installed per the instructions? Yes _________ No _________
7. What is the safe position of the valve? Fail closed _________ Fail open _________
8. For a DVC6010 or DVC6030: During full travel of the actuator, does the DVC6000 feedback arm move below
the “A” or above the “B” alignment positions? (It should not) Yes _________ No _________
