Pneumatic Connection Diagram for LVDT Weld Bodies with Retractable Pin
(Not
applicable to Clamp Mount Assemblies)
CenterLine recommends using a 3-position center open valve to extend and retract the weld
pin. The center open position reduces air consumption when the valve is de-energized.
CenterLine also recommends using a 3-port shuttle valve to ensure continuous air blow off in all
pin positions.
While referring to the diagram in Figure 6, please consider the following:
•
In home/load position, the solenoid extending the pin should be energized to facilitate
loading and locating the stamping and/or location of fastener.
•
After a weld complete signal is received, the solenoid extending the pin must be
de-energized, and the solenoid to retract the pin must be energized to facilitate the
removal of the finished part.
