Debugging Steps
Perform the following step in case the touchprobe doesn’t trigger or if the device exhibits unintended behavior.
Check the lights of the probe module and probe head when attaching and touching the probe carefully with a finger.
For TP-20:
The PH6 LED should be off when the TP-20 module is not attached
The PH6 LED should be on when the TP-20 module is attached
Touching 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.
TP-200:
The PH6 LED should be on when the TP-200 module is not attached
The PH6 LED should be on when the TP-200 module is attached
Touching the TP-200 module when InSpec is not set to touchprobe should cause:
the PH6 probe head LED not to blink but it will remain on
the TP-200 probe module LED should turn onTouching the TP-200 module when InSpec is set to touchprobe should cause:
the PH6 probe head LED should blink off
the TP-200 probe module LED should brighten by an amount commensurate with the probe force as it is deflected.
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.
The following Image shows the position of the PI-200 on a Vertex machine:
The following Image shows the position of the PI-200 on an Excel machine:
When the PI-200 box can be accessed, the DIP switch configuration should be compared to the reference which is presented below.
Possible Error Causes
The follwing table presents possible error causes based on the test results
PH6 LED | never on | never on | always on | always on | correct |
|---|---|---|---|---|---|
TP-200 LED | always on /never on | correct | |||
PI-200 | successfully detected | not detected | successfully detected | ||
Check if | PH6 is defective | PI-200 is powered PI-200 is connected correctly to:
| PH6 is defective | TP-200 is demaged | PI-200 or the cable between the PI-200 and the Logic Board is functioning |
