7.3 Events / malfunctions
Display and query of events and malfunctions
Events during operation can lead to a malfunctioning of the device. The last 10 (0-9) events and
malfunctions are stored in the „Events“ menu group (position „0“ = most recent event).
The device differentiates between 3 types of events:
Examples of
possible events
1. Messages with code Msg
Events for notification only (e.g. factory setting after a malfunction in the Eprom automatically
loaded, message not after loading the factory setting via PIN).
2. Alarms with code AL
Events during which the device automatically restarts operation after the cause of the
malfunction has been remedied (e.g. mains failure), or remains in operation (e.g. externally-
trunked centralized fault).
3.Error with code Err
Events that lead to a disconnection of the controlled output (e.g. excess motor temperature).
Restarting is only possible after a reset (locked).
A momentary pending alarm or error message is indicated by a blinking indicator and appears alternately with the
standard display. In addition, it is signaled via the 3-internal LED’s.
