Presentation on theme: "Travel Sensor Is Factory Adjusted"— Presentation transcript:

1 Travel Sensor Is Factory Adjusted
The placement of the feedback arm on the travel sensor is factory adjusted and sealed with anti-tamper paint. This setting has been tested for functionality successfully several times before the DVC6000 ships from the factory. Do not assume this setting is wrong. Check everything else first before disturbing the anti-tamper paint. Anti-Tamper Paint

2 DVC6000 – Potentiometer Issues
Potentiometer Components

3 Vibration Induced Potentiometer Wear
Some control systems are not grounded Valve Travels in Higher Resistance Area (80 – 90% travel) Amplification of travel noise by velocity gain in the DVC tuning ( Reduce affect by changing to velocity gain of 0)

4 No Potentiometer Wear

5 ValveLink Graph with Potentiometer Wear-Thru

6 Profile Test Requires PD Tier

7 PD Profile No problems

8 PD Profile Test Showing Early Wear

9 Increase Reliability with Linkage-less feedback
Feedback Arrays Best to remove potential wear points all together Unique linkage-less non-contact design Feedback components never touch the instrument DVC2000 Released in 2004 DVC6200 HART DVC6200f FOUNDATION Fieldbus No Linkages

10 DVC Product Details Differences between the DVC6200 & the DVC6000 Hall sensor in place of the feedback potentiometer Terminal box moves to the left side of the housing New mounting kits (same design as DVC2000 kits) HART: Firmware 10 required FOUNDATION fieldbus: new PWB and terminal box required What doesn’t change: Relay A, B, and C (standard and low bleed) Diagnostic tiers Fieldbus control tiers I/P converter Natural gas certified Extreme temperature Performance & Reliability Same performance & reliability of the DVC6000 All approvals currently available for the DVC6000 2009 FIELDVUE Champion Training

11 DVC Mounting Kits Bolt patterns for DVC2000 and DVC6200 are identical Existing DVC2000 mounting kits are being updated 1 standard kit for both DVC6200 and DVC2000 Stronger brackets will replace the existing brackets to accommodate additional weight New curved array For use with the existing long stroke cams For Fisher rotary actuator window 1”, 2” & 4” array Rotary Magnet Curved array 2009 FIELDVUE Champion Training
