CHAPTER 1: DESCRIPTION
STA SERIES AC CONTROLS
1-8 990-351
Cylinder Air Hose Connections
If your Control uses Force Control, the air hoses
for the Differential Pressure Sensors are located
on a panel on the top of the Control.
In the example on the right, this Control is
equipped with HIGH and LOW fittings for
channels 1 and 2.
Standard ¼ NPT female fittings are supplied by
the factory, but the customer must supply air
connections and hoses in order to connect the
Control to the HIGH and LOW connections on
the weld head(s). The HIGH fitting should be
connected to the top (high-pressure side) of the
cylinder that supplies welding force. The LOW
fitting is connected to the bottom (low-pressure
side) of that same cylinder. Make the connection
to the weldhead as close to the cylinder as
possible in order to get accurate readings.
Internal Access
Access to the internal components is obtained by opening the door, which is secured with a screw-operated
latch. There are no operator adjustments inside of the unit, so the door should not need to be opened except
for initial installation (electrical connections) and for repair of components.
NOTE: If your unit is equipped with a circuit breaker, that breaker must be de-energized to open the door
and access the components.
