Accessories
Optional Accessories
Press Tool Adapter for PST
The press tool adapter allows customer tooling to be set in a specific angle around the pressing axis.
It should be used for applications with pulling forces.
Remove the two screws (2x) and assemble the press tool adapter on to the press piston.
Assemble the two (2x) screws and tighten according to table.
Press Force Transducer
The press force validation transducer is used together with the STanalyser/STa 6000 to measure press force in the actual application, to calibrate the PST to the actual application or as a regular quality control of the PST. See STanalyzer/STa 6000 documentation for operating instructions.
TTS-QST Programming Cable
The TTS programming cable is used for programming QST/PST tools when motor or load cell have been changed.
