3.14.11 14-9* Fault Settings
14-90 Fault Level
This is an array parameter with 26 elements. Each of the bits can
be configured to any of the following options. Use this
parameter to customize fault levels.
Option: Function:
[0] Off Use [0] Off with caution as it ignores all
warnings and alarms for the selected
source.
[1] Warning
[2] Trip Changing a fault level from default option
[3] Trip Lock to [2] Trip leads to the
automatic reset of the alarm. For alarms
involving overcurrent, the frequency
converter has a hardware protection that
issues a 3-minute recovery after 2
consecutive overcurrent incidents. This
hardware protection cannot be overruled.
[3] Trip Lock
[4] Trip w. delayed This option adds a delay between
reset automatic resets, otherwise it is the same
as option [2] Trip. The delay prevents a
situation where reset is attempted
repeatedly for an overcurrent situation.
Hardware protection of the frequency
converter forces the 3-minute recovery time
after 2 consecutive overcurrents (within a
short time window).
