DISPLAY ALARMS
Options Available:
LCP100 Local Control Panel or
external pushbutton
SIL 2 Capable 420 mA position
transmitter or discrete switch
Discrete switch can be configured
for position or alert annunciation
Notes:
‐ DVC6200 SIS with Relay B in ETT
configuration for PST diagnostic only
Loss of pneumatic supply to DVC6200 SIS
exhausts air to valve
ESDV STATUS

Benefits:
Prevents spurious trips on loss of
electrical power to DVC6200 SIS
PST with DVC6200 SIS provides
diagnostic coverage
Trigger diagnostics captures safety
demand and reset
‐Solenoid health monitoring
AI or DI*
Example Drawing Only, may require modifications to meet site specific requirements
*Position Monitor AI or DI may reside in SIS or BPCS
**PC with ValveLink software or 475 Field Communicator can be used in lieu of multiplexer
***HF341/HF340 may be required with legacy hosts to provide proper impedance to support HART communication
