Explanation of the status displays
CUS After a reboot of the CU first the archives of the corrector are read. Here in the first 4
digits from the left, the archive number is displayed (e.g. 98200000, 98400000). Then
all necessary parameters are read. This is done using a matrix, where the column
stands in the first digit, the next three digits are reserved for the rows and the last 4
digits indicate the Modbus address of the parameter specified. Since the transmission
is faster than the display output, displaying occurs in jumps (eg 20734938, 20784940).
96
If this transfer was successful, then 00000002 will be displayed. This means that now
the standard transfer begins between corrector and CU and the restart was successful.
Now in the first 4 digits a counter runs that counts the number of transfers (circular
from 1 to 8888), so that the display might look as follows: e.g. 12450002, 12510002.
Here again, the transfer is faster than the display output.
If now an archive entry is generated and then retrieved by the CU, the number of ar-
chive is visible in the display for a short time (e.g. 99200002). Thereafter, the counter
of the standard transfer is reset and begins to count again.
If an error is detected during restart, the display will remain for a short time at the point
where the error occurred. This is followed by a reset of the CU and the start sequence
begins again.
Signal Strength of the radio signal: <12= critical signal strength, use any external antenna if
necessary, strength 12-21= satisfactory to good signal strength, strength >21= good to
very good signal strength.

-1 PIN is missing
-2 PIN not numerical
-3 Command echo on
-4 Error in the AT sequence "AT+CPIN?"
-5 After AT sequence "AT+CPIN=pin"
-6 PIN or PUK incorrect less than three times.
-7 PIN or PUK incorrect three times (PIN and PUK are no longer accepted.).
If the PIN has been entered incorrectly three times, now the PUK must be entered to re-
lease the PIN.
-8 PUK, PIN incorrectly more three times (entries will not be executed.).
If PUK has been entered incorrectly more than three times and the PIN has been en-
tered incorrectly more than three times, the release of the SIM card must be requested
from the network provider.
-9 After AT sequence "AT+CPIN=PIN" an error message is generated (PIN not accepted)
-10 After AT sequence "AT+CPIN=PIN" unknown response (PIN not accepted)
-11 PIN information faulty in connection with GPRS3
-100 After AT sequence "AT+CREG?" query failed
-> PIN query
-> PIN not OK
