2. Description of the Device

The Fisher DVC6200 SIS 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 SIS instrument with electronics hardware revision 2 (HW2) and firmware revision 4, 5, and 6 with the following product options.

6. Safety Instrumented System Design

When using the DVC6200 SIS 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

avg

can meet SIL 1 @ HFT=0.

6.2. Safety Function

D Deenergize to Trip Application: The application of the digital valve controller is limited for SIS

to low demand mode. Table 1 describes the normal and safe states of DVC6200 SIS for a DETT configuration. The digital valve controller may be operated with one of the following control signals:

D 024 VDC: Normal operation is with a 24 VDC signal applied to the digital valve

controller. A shutdown command is issued by interrupting the loop or taking the voltage signal to 1 VDC or less.
