Upper/lower current warning limit
You can enter an upper and/or a lower current warning limit value. If the current warning
values are exceeded or undershot, the motor starter responds with a warning message
without tripping. The warning message is acknowledged as soon as the warning threshold is
exceeded or undershot by 5%.
Note
The current warning thresholds are activated by default. You can deactivate the current
warning thresholds, however. The current warning thresholds are not activated until the
CLASS time expires.
