The Servo Pro accepts signals from the optional
Local Control Box which may be mounted integrally or
remotely.

from the local Control Box and ignores the command
signal from the remote process controller
Off – The Servo Pro will not respond to position signals
from either the local Control Box or the command signal
from the remote process controller
Remote – The Servo Pro responds to the command
signal from the remote process controller and ignores
position signals from the local Control Box.
Open / Stop / Close Switch

open direction
Stop – the Servo Pro will stop the actuator motor
Close – the Servo Pro powers the actuator motor in the
closed direction.
