Touch probe not
ready
 The touch probe is not connected.
 Battery dead
 No connection between infrared probe
system and receiver unit.
 Connect the touch probe.
 Replace the battery.
 Clean the receiver unit.
 Penetration of humidity
 Touch probe cable defective
 Cable to transmitter/receiver unit defective
 Contamination of probe and/or transmitter/
receiver unit --> No infrared connection
 Obstacle in the infrared connection or strong
shading of transmitter or receiver.
 It is possible, that several touch probes are
within the receiving range of a SE; the
infrared signals cannot be allocated any
more; faulty operation.
 Interface to touch probe or transmitter/
receiver unit on MC defective
 Dry the touch probe.
 Replace the cable.
 Clean touch probe and transmitter/receiver
unit
 Remove obstacle from infrared connection.
 Readjust receive range of SE.
 If the interface to touch probe or transmitter/
receiver unit on the MC is defective -->
Replace MC (See “Exchange of
HEIDENHAIN Components” on page 28 –
523).
 See “Touch Probe” on page 25 – 413.
TNC temperature
warning %dC
 The temperature sensor in the control has
detected an excessively high temperature
inside the control housing. If the
temperature continues to increase, the
control hardware may be damaged.
 Check the heat transfer in the electrical
cabinet.
 Check the fan in the control.
 See “Information Menu” on page 17 – 267.
 See “Temperature monitoring” on page 3 –
674.
 See “Temperature” on page 6 – 75.
TNC temperature
too high %d°C
 The temperature sensor in the LE has
detected an excessively high temperature
inside the control housing.
 Check for adequate heat transfer in the
electrical cabinet.
 Check the fan of the logic unit.
 See “Information Menu” on page 17 – 267.
 See “Temperature monitoring” on page 3 –
674.
 See “Temperature” on page 6 – 75.
TS: Inadequate
consistency
 During multiple measurement with the
automatic probe cycle the variance of the
individual measured values is greater than
the value defined in machine parameter
MP6171.
 Check whether the probe point and the
stylus are clean.
 Expand
the tolerance in machine parameter
6171.
 See “T
ouch Probe” on page 25 – 413.
5-V power supply
too high
 The 5V supply voltage of the control is too
high.
 Check the power supply.
 Inform your service agency.
 See “Power Supply” on page 17 – 251.
 See “Error Localization by Process of
Exclusion” on page 6 – 66.
