This guide provides installation, operation, safety, maintenance, and specifications for Renishaw HPPA and TSI 2/TSI 2-C tool‑setting system.
The HPPA (High‑precision pulldown arm) together with the TSI 2 and TSI 2‑C interfaces form a tool‑setting solution for high‑precision measurement of cutting tools, primarily on CNC turning machines. The system includes a manual arm, probe, stylus, and interface units that connect to the machine controller.
The document covers everything needed to install the arm and interface, wiring diagrams, probe connection details, tool‑setting procedures, calibration, routine maintenance, fault‑finding, and a complete parts list. Safety instructions, recommended power supplies, and grounding requirements are also provided.
| Probe status LED colors | Green = arm ready/probe seated, Red = triggered |
|---|---|
| Stylus length | 15 mm (0.59 in) |
| Probe contact resistance limit | < 1 kΩ |
| Intended machine type | CNC turning machines |
Power must be switched off and the power supply to the TSI 2 or TSI 2‑C disconnected. The installer should also follow local electrical safety requirements and ensure proper grounding.
It provides a high‑precision tool‑setting solution that allows manual presentation of a probe into the machine’s working envelope for accurate measurement of cutting tools.
