5. Error messages
Altogether 6 different error messages may be displayed:
5.1 Error messages E1/-E1
The error messages E1/-E1 will appear, if the actual input signal exceeds
the programmed maximum signal value (10 V or 20 mA) by more than
9% or if it falls below the minimum signal value (0 V, 0 mA or 4 mA) by
more than 9 % of the maximum signal value, because the inbuilt A/D
converter is overloaded. E1 indicates a too high signal, -E1 indicates a
too low signal. Below table indicates the actual values at which this error
message will appear:
Message Set input signal Actual signal
E1 0 ... 10 V > 10.9 V
0 ... 20 mA > 21.8 mA
4 ... 20 mA > 21.8 mA
-E1 0 ... 10 V < -0.9 V
0 ... 20 mA < -1.8 mA
4 ... 20 mA < 2.2 mA
5.2 Error messages E2/-E2
E2 appears if the input value exceeds the corresponding indication of
+1999 digits. -E2 appears if the input value exceeds the corresponding
indication of -1999 digits.
5.3 Error messages E3/-E3
5.3.1 Error message E3
E3 will appear, if the actual input signal exceeds the maximum signal
value (10 V or 20 mA) by more than 6 %. This is still within the capacity
of the inbuilt A/D converter (see also 5.1).
If the value to display is still within the capacity of the indicator, the value
and the respective error message will flash intermittently. If the value
exceeds ±1999, E3 will be displayed permanently.
