9.4 Fault stack
The last 128 faults are stored with the
timestamp in the fault stack. The faults are
stored in chronological order. A display
routine makes it possible to display the fault
messages on the LC display in plain text. The
following is displayed:
 the date,

the time,
 the fault,
 and in case of floor-based faults, even the floor and the registered floor
designation.
The “Right" key can be used to open a fault
entry. The position, speed and a selection
of important signals, which were present at
the moment of the event, will then become
visible.
It is thus possible to understand a history of
the faults that have occurred most recently.
To delete the stack, press the »OK« key and
also respond to the security query with the
»OK« key. For complete logging, we recommend deleting the fault stack only after
the entries have been transmitted to a WinMOS
® 300control centre or to the cloud.
9.5 Fault list
The number of all registered faults is stored in the fault list. The following is
displayed:
 the fault,
 the frequency,

and in case of floor-based faults, even the floor.
A display routine makes it possible to read the fault list on the LC display in plain
text.
To delete the list, press the »OK« key and respond to the security query with the
»OK« key. For complete logging, we recommend deleting the fault list only after
the entries have been transmitted to a WinMOS
® 300control centre or to the cloud.
