4.5 Warning/Alarm Messages
4.5.1 Warning/Alarm Code List
A warning or an alarm is signaled by the LEDs on the front
of the filter and by a code on the display.
A warning indicates a condition that may require attention
or a trend that may eventually require attention. A
warning remains active until the cause is no longer
present. Under some circumstances, operation may
continue.
A trip is the action when an alarm has appeared. The trip
removes power injection to the grid and can be reset after
the condition has been cleared by pressing the [reset]
button or through a digital input (parameter 5-1*). The
event that caused an alarm cannot damage the filter or
cause a dangerous condition. Alarms must be reset to
restart operation once their cause has been rectified.
This may be done in three ways:
1. Pressing the [reset] button on the LCP.
2. A digital reset input.
3. Serial communication reset signal.
