9.2 Emergency action
Fail-safe action is triggered by the i/p
converter or solenoid valve and upon supply
air failure. The positioner fully discharges its
pneumatic output to the atmosphere, causing
the mounted actuator to be vented. As a
result, the valve moves to the fail-safe
position. The fail-safe position depends on
how the springs are arranged in the
pneumatic actuator (air-to-close or air-to-
open).
When the supply air fails, the optional
solenoid valve or forced venting is triggered
and after reaching the shutdown signal, all
positioner functions, except open/closed
loop control, remain active (including
diagnostics as well as position and status
feedback).
Emergency action in the event of valve or ac
-
tuator failure is described in the associated
valve and actuator documentation.
Î
The plant operator is responsible for
emergency action to be taken in the
plant.
