8.3 Active Filter Warning and Alarm Definitions
NOTICE
After a manual reset pressing [Reset], press [Auto On] or [Hand On] to restart the unit.
If an alarm cannot be reset, the reason may be that its cause has not been rectified, or the alarm is trip-locked (see also
Table 8.1).
Alarms that are trip-locked offer additional protection, meaning that the mains supply must be switched off before the
alarm can be reset. After being switched back on, the unit is no longer blocked and may be reset as described in
chapter 8.2.2 Alarm Trip once the cause has been rectified.
Alarms that are not trip-locked can also be reset using the automatic reset function in 14-20 Reset Mode. Automatic wake-up
is possible during this type of reset.
If a warning and alarm is marked against a code in Table 8.1, either a warning occurs before an alarm, or the display for a
given fault (warning or alarm) is configurable.
