LI.42 Last Error (t-2)
LI.43 Last Error (t-3)
LI.44 Last Error (t-4)
LI.45 Last Error (t-5)
LI.46 Last Error (t-6)
LI.47 Last Error (t-7)

Value range
0000...5FFFh
Example The display shows following values:
Description The last error that occurred is stored in LI.41. The table shows for the most significant
LI.50 AN1 Display before amplification
Value range
0...65535
GB -54
Description
The parameters LI.41...48 show the last eight errors that occurred. The oldest error is in
LI.48. If a new error occurs, it is stored in LI.41. All other errors are moved one parameter
further. The oldest error (LI.48) is cancelled. The display of the error takes place in the
most significant word (Bit 12...15).
Between errors of the same type (e.g. twice OC) the time difference is determined. It is
stored in the three low-order words. The display is hexadecimal.

hex-value "3" the error E.OP (overvoltage).
Before that the error E.OL (LI.42=2xxx) occurred. Because it concerns two different errors,
no time difference was stored.
In LI.43 and LI.44 the error E.OH is stored. Since these errors are of the same type, a time
difference (here „023") is stored in the three low-order words of LI.43. The hexadecimal
value of 23 corresponds to a time difference of 35 minutes in decimal.
No errors are stored in LI.45...48.
Description
The parameter shows the value of the analog signal AN1 before the characteristic
amplification in percent. Depending on the setpoint setting the displayed value of
0...±100 % corresponds to 0...±10 V, 0...±20 mA or 4...20 mA.
