Status and fault signals
Detail description of status indications
General
In case of an irregularity, the display changes automatically from operation mode level to er-
ror display. Depending on the control unit connected BDE-E or BDE-M various indications
are given.
When using an electronic BDE-D
The background colour changes between normal/invers every 2 seconds. Several errors can
be displayed (e.g. 1/2 means: Error No. 1 of total 2 errors).
Temporary return to main display for 4 seconds after browsing through error dis-
plays.
Status notifications with a „W“ are warnings. In this case, the error relay does not switch.
The status can be reset by several means according to the detailed description.
A status can usually be deleted by pressing the key
for 5 seconds (= reset). This trig-
gers a restart in the control unit.
Information about the operator system, like e.g. the software version, can be read out of the
BDE-D main display by pressing the same key once again.
Telephone number, fault and maintenance are only displayed, when this function has been
activated by the service technician.
If the cause of the fault has not been eliminated, however, the status message will re-appear
if the fault occurs again.
The following list gives the causes of faults in decreasing probability. The fault at the bottom
of the list has the smallest probability of occurring in the STG.
