8.2 Warnings and error messages
When a malfunction occurs, ther
e is an optical and acoustic alarm
and the potential-free alarm contact switches.
Additional signal encoder for monitoring the con-
troller unit:
Alarms, which are sent from the operating unit or
controller unit, are placed at the potential-free alarm
output and can be connected to external signalling
equipment (acoustic or visual) by the customer.
In the event of alarms, the operating unit as well as
the controller unit outputs an acoustical signal.
This is adjustable on the operating unit. If the oper-
ating unit fails, only the controller unit beeps. If the
controller unit fails, the operating unit beeps.
The corresponding error code will appear on the
touchscreen. This additional beep also occurs in the
event of a door alarm.
The error can be queried via the
[Logbook]
button. As long as the
error message is not actively closed, it remains in the upper section
of the screen.
The alarms are shown graphically in the run-time diagram, so that an
error message which was actively clicked away is still comprehen-
sible. In addition, the alarms and events can be called via
‘Settings
Logbook’
If the closing of the alarm is prevented by a PIN prompt, please con-
tact a service technician.
When you contact the Service department, please report the error
number that is displayed.
