Error display: If the system is recognizing an error, the spanner (Spe-
cial symbol „g“) is flashing.
If Neutral is preselected on the Controller, a two-digit
error number appears on the two alphanumeric display
positions (central and right Side).
If more than one error is pending, the different error
numbers will be indicated one after the other on the
Display in cycles (about 1 second).
The error code will be only then indicated if
the Controller is in Neutral !
Warning display: At exceeding the warning threshold Temperature –
Sump / Retarder / behind the Converter and the war-
ning threshold Speed – Engine, changes the indication
on the Display to the actual gear and the corresponding
warning indicator.
If several warnings are simultaneously active,
only the warning with the highest priority will
be indicated.

Display EE Indication on the Display: EE (central and right Side).
In this state, the Display has a timeout, i. e. it receives
no Data from the EST-37.
Main reasons:
- EST-37 is in TOTAL RESETTING MODE
(e.g. because of output train disconnection or exter-
nal power supply at the lines to the gear-solenoid
valves).
-
EST-37 without supply
- Data line not correctly connected, etc.
1.6.3 Error code definition:
The error codes are composed of two hexadecimal numbers.
The first number indicates the kind of signal, the second number the signal and the kind of
error.
