Malfunctions

9.2

Emergency action

Upon failure of the air supply or electric signal, the positioner vents the actuator, causing the
valve to move to the fail-safe position determined by the actuator. Plant operators are re-
sponsible for emergency action to be taken in the plant.

Emergency action in the event of valve failure is described in the associated valve documen

tation.
