Table 8.1 Alarm/Warning Code List
A trip is the action when an alarm has appeared. The trip disables the active filter and can be reset by pressing [Reset] or
resetting via a digital input (parameter group 5-1* Digital Inputs [1] Reset). The origin event that caused an alarm cannot
damage the active filter or cause dangerous conditions. A trip lock is an action when an alarm occurs, which may cause
damage to active filter or connected parts. A trip lock situation can only be reset by a power cycling.
