Note: A hard wired input ESD will cause a shutdown action when the contact input is open
circuit. The individual actuator function on receipt of the ESD command is set within
the actuator itself. Valves may close, open or stay put during an ESD event.
Once an ESD command has been issued to the actuator field units, local control is
not available until a new command is sent from the master station to each actuator.
The new command may be open, close or stop.
