Subject to change (without notice)
HEIDENHAIN is constantly working on further developement of
its TNC controls. It is therefore possible that details of
a certain control may differ slightly of the control
version which is being described herein. For this reason it
may be necessary to request an updated service manual from
us.
Note
Reproduction of this service manual is not permitted without
our consent.
The TNC 114 contains sub-assemblies with CMOSelements.
Although MOS IC's are equipped with an input protection
diode network to eliminate the build-up of static
charges, care must be taken when handling these elements.
The following requirements in the work area must be met:
Prior to working with CMOScomponents or with assemblies
equipped with CMOSelements, all table coverings, all operated
instruments and/or tools, as well the work personnel, must be
properly grounded.
A portable "MOS-HANDLING-SET" for field service is necessary
when exchanging the operating software and/or servicing the
TNC 114.
1) a cable that equalizes potential differences
between conductive work surface and ground
2) a wristband that provides an electrical connection
between person and conductve work surface
3) a conductive work surface

Automatic fail diagnostics
With operating faults, an automatic fault message is
issued by the TNC 114 which simultaneously opens the
regulator release contact.
2.
Transducer is defective
The accompanying momentary position LED will blink
with a transducer defect.
Erasing the message:
Switch-off line voltage: switch-on line voltage after
fault has been remedied.
Internal test program
The internal test program will begin after switching-on.

the preset display must illuminate together with the
same intensity.

Faults of this type are coded by the TNC 114, the
lamps over the reference point keys will illuminate.
Erasing the message: if after switching-on the fault
message reappears, the TNC 114 must then be sent to
the factory for repair. (with noted lamp fault coding)
Positioning direction error The following fault conditions may occur:

Connect rotary encoder to X-axis input dummy connectors
on X and Z axis. Test the counting function in~positive
and negative directions of all axis and decades.
On the backside of the unit, the counting direction for
every axis can be selected using the DIL switch 1, 2 and 3.

Shaft over reference impulse, (REF LEDs off) press REF key,
press again and hold.
Rotate rotary encoder shaft until reference impulse stops
the display.
The displayed value must evaluate to:

Axis supervision
The axis supervision is active on all 3 axes within a
distance of 205 wn. The standstill of the remaining axes that
are momentary not controlled is supervised. The direction of
the momentary controlled axis is supervised.
Direction supervision test
Connect rotary encoder to transducer system input X-axis and
dummy connections on transducer input X- and Z-axis. Select
operating mode "absolute dimensioning". For example:
enter + 1000 and initiate traversing with the X-key.
Rotate rotary encoder counter clock-wise (minus direction).
With a value ) - 205 w the segments b, f, and q must luminate
on the preset display for all decades. (uuuuu~uu )
Repeat the test with negative positioning values and positive
rotation directions.
Repeat test for Y- and Z-axis.
Standstill supervision test
Connect rotary encoder on transducer syste&n X-axis input and
dummy connectors on transducer Y- and Z-axis inputs.
Start X-axis postioninq.
Connect rotary encoder to transducer system Y-axis input and
rotate shaft.
The error message (uuuuuuuu ) appears in
the preset display for a displayed momentary value of 3205 w.
Repeat the test in positive and negative directions for all
axes.

In order to exchange the operating program, the display
board must be demounted from the control.
Necessary tools: - IC extract/insertion tool
- small screwdriver
- remove EPROMfrom display board using extraction tool
- place EPRQMonto MOS protection mat
- insert new EPROMcorrectly using insertion tool
Important: - The inserted IC
must
be pointing in the same

- Before installing the board into the control,
visually check if all the IC pins are contacting
the IC socket.
After an operating program exchange the program nr. has to be
changed on the backside of the control.
