How do I calibrate my DVC6200?
Steps to Calibrate a DVC6200 Controller
- Hook up a HART® communicator to the DVC6200 in parallel with a 4-20 mA loop across the “loop” terminals.
- Apply a 4 mA signal to the DVC and power up the HART communicator.
- First, put the instrument in “not in service” mode.
- Choose “not in service” and press enter.
What is a DVC Fisher?
Fisher. The Fisher FIELDVUE DVC6200 instrument allows for your operation to run closer to setpoint, improving product quality with more accurate control. Using FIELDVUE Performance Diagnostics, valve operation is monitored online to evaluate performance and reliability.
What is a DVC valve?
DVCs are “the brains” of a control system. They are positioners that help regulate the position of a control valve by monitoring input from a transmitter and using that input to open or close a control valve.
What is a DVC6200?
The FIELDVUE DVC6200 SIS digital valve controller is a HARTr communicating instrument for use in valve applications such as Emergency Shutdown, Emergency Blow Down, Emergency Venting, and Emergency Isolation.
What is the difference between actuator and positioner?
Valve actuator – which moves the valve’s modulating element, such as ball or butterfly. Valve positioner – which ensures the valve has reached the desired degree of opening. This overcomes the problems of friction and wear.
How do you calibrate a DVC6000 positioner?
Steps to Calibrate a DVC6000 Controller
- This Mode needs to be changed to “Out of Service” during configuration.
- Next step is to teach positioner the equipment it is working with.
- After info is entered communicator will prompt you to enter Travel Calibration.
- Once Auto Travel Calibration is complete.
How do you calibrate a control valve positioner?
An Overview of Step-by-Step Calibration of Control Valve Positioner
- The measurable pressure range is shown on the supply gauge.
- Set the input value to the lowest reading value.
- Further slowly adjust the nozzle pin to get zero value.
- Then slowly increase the input pressure value to 3psi, and check if you get zero output.
