12.3 Warning and interference messages on the display
The control unit differentiates between events, warnings and
errors. The corresponding message is displayed.
Event messages "INFO"
Event messages inform about events such as "switching to battery
operation". The barrier continues to run normally. Event messages
do not influence the outputs of the control unit.
Warning messages "WARNING"
Faults that could be reset by the control unit are displayed as
warnings. Operation of the barrier is not or only briefly impaired.
If the function "Warning" has been chosen for an output, this output
is deactivated at pending warnings (fail safe).
Error messages "ERROR"
Faults that cannot be reset by the control unit are displayed as
errors. The barrier is shut down.
If the function "Error" has been chosen for an output, this output is
deactivated at pending warnings (fail safe).
To take the barrier into operation again, the fault must be removed
by an MHTM MicroDrive service specialist and a reset according to
chapter 12.4 must be performed.
For requirements to the MHTM MicroDrive service specialist,
see page 18, chapter 2.4.
NOTE!
With some messages, the control unit tries to reset
the cause of the message. If the attempt was
successful, the message is displayed as
WARNING. If the attempt failed, the message is
