Instruction Manual Supplement

D104564X012

2. Description of the Device

The Fisher DVC6200 digital valve controller is an instrument which delivers controlled pneumatic
pressure to modulate a valve actuator in response to an electrical signal. An optional valve position
monitor will either transmit a 420 mA signal in response to the actual valve travel or open and
close a discrete limit switch based on a configurable trip point.

This safety manual applies to the DVC6200 instrument with electronics hardware revision 2 (HW2)
and firmware revision 4, 5, 6, and 7 with the following product options.

6. Safety Instrumented System Design

When using the DVC6200 digital valve controller in a safety instrumented system, the following
items must be reviewed and considered.

6.1 SIL Capability

6.2 Safety Function

6.3 Failure Rates

6.4 Application Limits

6.5 Environmental Limits

6.6 Application of the Switch Output for Diagnostic Annunciation

6.1. SIL Capability

D Systematic Integrity

SIL 3 Capable— the digital valve controller has met manufacturer design process
requirements of IEC 61508 Safety Integrity Level 3.

D Random Integrity

D The digital valve controller is classified as a Type A device according to IEC 61508. The

complete final element subsystem will need to be evaluated to determine the SFF. If the
SFF of the subsystem is >90%, and the PFD

< 103, the design can meet SIL 3 @ HFT=0.

D The position monitor is classified as a Type B device according to IEC 61508. The

complete final element subsystem will need to be evaluated to determine the SFF. If the
SFF of the subsystem is >90%, and the PFD
If the SFF of the subsystem is between 60% and 90%, and the PFD

< 102, the design can meet SIL 2 @ HFT=0.

avg

< 101, the design
