TP20 warnings
The use of eye protection is recommended. Pinch hazards exist between parts and between moving and static parts. Beware of unexpected movement. You should remain outside the full working envelope of probe head / extension bar / probe combinations.
It is the machine supplier's responsibility to ensure that the user is made aware of any hazards involved in operation, including those mentioned in Renishaw product documentation, and to ensure that adequate guards and safety interlocks are provided.
Under certain circumstances, the probe signal may falsely indicate a probe seated condition. Do not rely on probe signals to stop the machine.
Limitations of use
CAUTION: One option of the TP20 probe system uses a magnetically-actuated inhibit system. It is important to apply the following limitations when using the inhibit version TP20. Neglecting to do so may result in failure of the probe to trigger.
- The inhibit TP20 may not be armed at a distance of up to 100 mm from the front of the MCR20 probe module change rack.
- Do not use the inhibit TP20 to gauge magnetised parts or parts held in magnetic fixtures.
- Do not use the Renishaw PE series extension bars with the inhibit TP20 unless they have been fully de-magnetised. In all these instances the use of the non-inhibit TP20 probe body will ensure that the probe system operates fully.
CAUTION: The TP20 non-inhibit probe can only be used for automatic stylus changing using the MCR20 probe module change rack when the probe inhibit is controlled by the CMM. In the case of any uncertainty, do not attempt to perform automatic stylus changing with a TP20 non-inhibit probe and an MCR20 until the CMM supplier has checked the CMM for compliance to this requirement.
