Possible Causes Of Errors - HEIDENHAIN iTNC 530 Service Manual

25.2 Possible Causes of Errors

General:
Specifically for touch probes with infrared transmission:
Specifically for touch probe with air turbine generator (TS 444)
Especially for laser systems:
July 2010
Touch probe not ready
Collision (stylus, probe or transmitter/receiver unit damaged)
Humidity
Short circuit in the cable, in the transmitter/receiver unit or in the touch probe
Heavy contamination
Shocks or vibrations
Electromagnetic interference
Touch probe cable or connector defective
Touch probe defective
Interface of probe on MC defective
Caution
The power supply of the touch probes is not monitored.
A defective probe or a probe with penetrated humidity may influence the 5 Vdc and 15 Vdc
supply voltages of the control. This also applies for a defective or wet transmitter/receiver
unit.
This can lead to various disturbances of the control, even to a black screen. It is possible
that also error messages are displayed that do not immediately refer to a defective touch
probe or transceiver unit.
In this case try to operate the control without touch probe (See "Deselecting and
Disconnecting the Touch Probe" on page 25 – 426) to find out whether the disturbances
and error messages mentioned still are generated on the machine.
Battery flat (capactiy below 10 %).
--> In this case the message Exchange touch probe battery is output, when a probing
operation is started.
No infrared connection due to contamination of the probe or the transceiver unit
Obstacle in the infrared connection or strong shading of transmitter or receiver.
Contact on infrared touch probe not closed or defective
Several touch probes may be within the receiving range of one SE; the infrared signals cannot
be allocated any more; faulty operation
Cable to transceiver unit defective
Interface to transceiver unit on the MC is defective.
Compressed air supply for integrated turbine generator missing
Air turbine generator or capacitors defective
Note
If the capacitors in the TS 444 cannot be sufficiently charged, the touch probe outputs a
battery warning. This means that the error message
Exchange touch probe battery is displayed. With the TS 444, this is of course not
required. Find the actual error cause!
Damage to the housing
Compressed air missing
(for opening the protective cover for the transmitting and receiving of the laser beam and for
the blowing unit)
