Problem

This article includes instructions to troubleshoot the touchprobe on P2 Machines featuring a PH6 probe head and a TP-20 or TP-200 probe module.

The following picture shows the LED on the PH6 probe head:

Solution

Perform the following step in case the touchprobe doesn’t trigger or if the device exhibits unintended behavior.

  1. Check the lights of the probe module and probe head when attaching and triggering the touchprobe carefully with a finger.

    1. For TP-20:

      1. The PH6 LED should be off when the TP-20 module is not attached

      2. The PH6 LED should be on when the TP-20 module is attached

      3. Triggering the TP-20 module should blink the PH6 probe head LED off, regardless of whether the touchprobe is the active sensor in InSpec or not.

    2. TP-200:

      1. The PH6 LED should be on when the TP-200 module is not attached

      2. The PH6 LED should be on when the TP-200 module is attached

      3. Triggering the TP-200 module when InSpec is not set to touchprobe should:
        the PH6 probe head LED should not blink but it will remain on
        the TP-200 probe module LED should remain off

      4. Triggering the TP-200 module when InSpec is set to touchprobe:
        the PH6 probe head LED should blink off
        the TP-200 probe module LED should light up with a brighten by an amount commensurate with the probe force as it is deflected.

  2. Check the DIP switches of the PI-200 probe interface. Accessing this box might require to disassemble parts of the machine and should only be executed by Micro-Vu dealers.

    When the PI-200 box can be accessed, the DIP switch configuration should be compared to the reference which is presented below.

  3. Additional information and instructions to perform testing with a TP-200 in motorscope can be found at Checking the TP-200 Touch Probe State
