corresponding event messages. After an event occurs, the event message is
immediately displayed on the monitoring system.
If an event message is displayed, this can be hidden by pressing the
key. The events are recorded and can be displayed in an event overview.
Possible events are, for example, general status reports, when limit values
are exceeded or function faults. You can find a detailed list of the possible
event messages in the operating instructions provided.
The events are marked in color depending on their priority:
Green General status message.
Yellow Announcement or advance warning. Determine the cause of
the event message. You can continue to operate the on-
load tap-changer without any limitations.

inputs. These events acknowledge themselves as soon as the signal reas-
sumes a valid value. All other events have to be acknowledged by the oper-
ator.
If you acknowledge an event message, this is no longer displayed in the
event overview. If the cause of the event message is not remedied, the
event message reappears immediately.
Contact Maschinenfabrik Reinhausen before acknowledging a red event. If
