8 Action in case of faults
8.1 Fault indication
Various indications are given for an irregularity or fault depending on the control
unit connected BDE-E or BDE-M.
When using a mechanical BDE (control toggle switch)
With the mechanical control unit it is not possible to display a detailed status sig-
nal. If a fault occurs (will be shown by the status signal on the side cover), please
proceed according to section 8.2.
When using an electronic BDE-D
General
Any current operational faults in the drive system will be displayed in the Standard
screen. If several faults are active, they will be numbered: e.g. Fault 1/2
In case of an irregularity the display changes automatically from mode of operation
level to error display. Every 2 seconds the backlight changes between normal
/invers. Several errors can be displayed (e.g. 1/2 means: error no. 1 of total 2 er-
rors).
After 10 seconds the telephone number of the responsible service centre is indi-
cated alternating to the fault indication. The failure indication and the phone num-
ber change every 5 seconds, while the inverse flashing is remaining. The de-
scribed sequence applies to all failures. However, previously the phone number
must have been given by an authorised specialised person.
Information about the drive system, such as the software version, can be read out
by pressing the key.
After pressing this key once again, the phone number of the responsible service
centre and the last appeared fault indication is displayed in the screen. If the fault
message consists of several lines the first line will be displayed only.
Status signals with a "W" are warnings. For these the fault relay contact output is
not connected. Elimination of the irregularity leading to the status signal is per-
formed according to section 8.2
A status can usually be deleted by pressing the key for 5 s (= Reset). This pro-
duces a new start in the control unit.
If, however, the cause of the fault has not been eliminated, the status message will
appear again if the fault occurs again.
