4.3 Initial troubleshooting using state display 1

Basic statements about actual controller state can be made based on the state display 1:
- Is the lift in normal operation or in error state?
- Is the safety circuit available?
- Is the lift inside door zone?
- Are special features enabled?
- .....
Further troubleshooting can be made on the basis of the state display 1 .
The precise structure of the individual state displays is described in detail in the section
"State displays".

4.4 Error stack

Within the error stack the last 50 errors with timestamp are stored. However, it will not
appear in the error stack when an error is removed again.
Each error is displayed within 2 lines. In the upper line the date and time of the occurrence of
this error is displayed ("timestamp"), eg "22.04.15 12:34:45". The next line shows the type of
error, for example, "Drive Error". For some errors it is still displayed behind which control
module has diagnosed the problem.
Use the cursor keys to scroll in the error stack.
By pressing ENTER, you can see more details to the error on which the cursor is currently
displayed (Example) :
Drive error
Error no. 160/0 Internal error number
When this LED flashes every second, the software of this
module is running (The lift controller can of course still have
a fault at this time).
The "RUN" LED is on (almost) every control module.
: The lift is currently in an error state.
In the absence of this fault, the lift will automatically return to
normal operation.
Maintenance is necessary.
This LED is also set if, for example, the lift is still in
operation, but an ESE or TSE module is defective or become
more frequent in error (see "Error Warning")
