NOTE!
After a manual reset using the [Reset] button on the LCP,
the [Auto On] button must be pressed to restart the unit.
A trip lock is an action when an alarm occurs which may
cause damage to the filter or connected equipment.
Injection towards grid is stopped. A trip lock can only be
reset after the condition is cleared by cycling power. Once
the problem has been rectified, only the alarm continues
flashing until the filter is reset.
An X marked in Table 4.2 means that action occurs. A
warning precedes an alarm.
