25.6 Deselecting and Disconnecting the Touch Probe
You assume that a defective touch probe impairs the low voltages of the control.
Now, you want to test the control function without touch probe connected.
Proceed as follows:
8 Close all active probing cycles.
8 Remove the touch probe from the spindle (by hand or automatically).
8 Press the EMERGENCY STOP button and shut down the control.
8 Switch off the machine.
8 Disconnect the touch probe systems from the control (connector X12 and X13).
8 Switch the machine back on again.
8 Observe, whether error messages are repeated or error conditions recur.
