7.4 Warning and Alarm Definitions - Filter (Left LCP)

NOTICE
This section covers warnings and alarms on the filter side LCP. For warning and alarms for the frequency converter, see
chapter 7.3 Warnings and Alarm Definitions - Frequency Converter
A warning or an alarm is signalled by the relevant LED on the front of the filter and indicated by a code on the display.
A warning remains active until its cause is no longer present. Under certain circumstances operation of the unit may still be
continued. Warning messages may be critical, but are not necessarily so.
In the event of an alarm, the unit has tripped. To restart operation, reset the rectified alarms.
This may be done in 4 ways:
1. By pressing [Reset].
2. Via a digital input with the Reset function.
3. Via serial communication/optional fieldbus.
4. By resetting automatically using the [Auto Reset] function.
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 7.6).
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 above 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 (Warning: automatic
wake-up is possible)
If a warning and alarm is marked against a code in Table 7.6, either a warning occurs before an alarm, or it can be specified
whether it is a warning or an alarm that is to be displayed for a given fault.
