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)
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.
49
The command is not known or not permitted.
Check command or reconfigure the control unit.
9.5
Faults concerning Measuring operation
No. Cause
Remedy
51
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
52
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
53
Internal DC/DC converter is defective.
Exchange hardware
54
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
For Demo mode only:
If the faults 51 to 54 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.
9.6
Faults concerning Keyboard
No. Cause
Remedy
55
The change of system or program parameter is not
possible because a serial fieldbus function is active
(e.g. Teach-in or Measurement start).
Await completion of fieldbus function or stop it.
56
The change of system or program parameter is not
possible because a parallel function is active
(e.g. Teach-In or Measurement start).
Await completion of parallel function or stop it.
57
The change of system or program parameter is not
possible because a parameter channel is open.
Close parameter channel.
