  • Page 8: Introduction

    Introduction   Introduction The PI 7-2 is a dedicated signal conditioner for interfacing the TP7M series of probes or touch-trigger probe types such as TP2, TP20 or TP6/TP6A, to the CMM controller.

  • Page 9: Product Description

    2.  Technical description The PI 7-2 automatically recognises the probe type, determines the probe status, which is either triggered or seated (armed), and transmits debounced signals to the CMM controller. Status and control signals are transferred between the PI 7-2 interface, other Renishaw equipment and the CMM controller via the product interconnection system (PICS) ports.

  • Page 11: Reset Switch

    Product description 2.  Reset switch Automatically, the probe will reset to the armed state when the PI 7-2 is powered up. Occasionally, it may be necessary to perform a manual reset, for example after changing the probe stylus. Press the RESET button on the front panel for 2 seconds to reset the probe to the armed (seated) state.

  • Page 13 Product description Switch  With switch 3 UP, the PI 7-2 will automatically change operating modes from TP7M to kinematic probe types (TP2, TP20 or TP6/TP6A) when a TP6A probe or PAA series adapter is attached to the Renishaw autojoint connector on the probe head. Switch 3 should be set to the DOWN position only when it is necessary to connect a kinematic probe or an electronic trigger, from an external source, to the PICS input connector.
  • Page 14 Set switch 9 UP to select level 2. This will reduce sensitivity to vibration but with a small loss of measuring accuracy. NOTE:  All configuration switches are hardware controlled and do not require the PI 7-2 to be switched off and on again to make the selection active.
