10.4 Local Control Station
The local control station is a field or factory installable option that gives the operator
the ability to locally drive the Series 70 actuator with electrical power; overriding
the control signal from the process controller. The control station has a red (closed)
and green (open) light to provide end-of-travel indication. It also has two 3-position
switches as shown in Figure 17.

controller.
