9.4 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 E20.
Numerical characters in the data format require a
number. (e.g. 00.011MM or 01.0000MM)
42
The requested serial function is not possible, because the
unit was configured to “internal control”.
Configure the control unit to “external control”. For
“internal control” only the following commands are
permissible:
- Send measurement data
- Delete error code
44
The requested function is not possible, because of an
active parallel input (parallel function).
Deactivate the parallel input and await completion
of the parallel function, then restart the serial
transmission.
45
The transmitted value is out of the defined range (e.g.
Program no. > 255)
Repeat data transmission with correct values.
46 The function is not operational because the menu is open. Close the menu and repeat data transmission.
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.
9.5 Faults concerning measuring operation
No. Cause Remedy
51 a) Measuring time is not realistic (too short)
b) Wrong sensor selected
c) The zero adjust was done with sheet
a) Exchange sensor.
b) Set sensor on sheet >2.5 mm and select correct
sensor.
c) Perform zero adjust without sheet
52 Internal DC/DC converter is defective. Exchange hardware.
53
The selected sensor at the inputs „sensor selection A and
B“ is not valid. Example: Sensor no. 4 is selected but only
two sensors are configured.
Select the correct sensor.
54
The current between sensor and unit was short circuited
during measurement.
S1 = Sensor 1
S2 = Sensor 2
S3 = Sensor 3
S4 = Sensor 4
Check cable and connectors, exchange sensor.
55
The current between sensor and unit was interrupted
during measurement.
S1 = Sensor 1
S2 = Sensor 2
S3 = Sensor 3
S4 = Sensor 4
Check cable and connectors, exchange sensor.
Check whether the sensor was removed during
measurement (counter induction).
For Demo mode only:
If the faults 51 to 55 appear due to wrongly set values for sensor type / number of sensors /
sensor sequence, then the correct configuration can only be established by directly entering the
configuration menu (by simultaneously pressing all 4 operation keys) and setting the correct
values. Only then the fault condition will be redressed.
