9.4
Faults concerning Teach-In
No.
Cause
Remedy
30
The sheet cannot be taught because there is no
sheet in front of the sensor or the sheet thickness is
wrong.
Check sheet for correct thickness.
Repeat Teach-In.
If fault appears again, the sensor might be defective.
31
Automatic material detection is not possible.
Select material manually.
32
For LM material (slightly magnetical) only material
with a thickness of up to 2mm can be measured.

9.5
Faults concerning RS232 Transmission
No.
Cause
Remedy
40
Checksum does not correspond to transmitted
information
Check program and data transmission connection
41
Dimension is incorrect
(mm instead of in. or in. instead of mm)
or no numerical character at the position expected
(e.g. --.00MM instead of 00.001MM).
Compare transmitted dimension and dimension in the
parameter set at UDK20.
Numerical characters in the data format require a
number. (e.g. 00.011MM or 01.0000MM)
45
The transmitted value is out of the defined range
(e.g. Program no. > 255)
Repeat data transmission with correct values.
47
The serial commands are following too fast.
Include a small pause between the individual serial
values.
48
A serial function was started although another serial
function was still active.
Await completion of the active serial function, then restart
the serial transmission.
49
The command is not known.
Check command.
9.6
Faults concerning measuring operation
No.
Cause
Remedy
50
The AD converter or hardware is defective.
Change AD converter / hardware.
51
The current between sensor and unit was interrupted
during measurement.
Check cable and connectors.
Check whether the sensor was removed during
measurement (Counter-induction).
52
a) Measuring time is not realistic (too short)
b) The zero adjust was done with sheet
a) Exchange sensor
b) Perform zero adjust without sheet
53
Shortcut inside of sensor / sensor cable (also
between lead and shields).
Exchange sensor / cable.
54
Before measuring, the following items must have
been performed:
•
nominal thickness was entered
•
Zero adjust was performed
•
Teach-In was performed
•
Enter nominal thickness
•
Perform Zero adjust
•
Perform Teach-In
9.7
Faults concerning keyboard
No.
Cause
Remedy
56
Parameters cannot be changed, since a parallel
function is active (e.g. “Teach-In” or “Measurement
start”).
Await completion of active serial function or stop it.
