5.1 Warnings, alarms, and alarm resetting
5
Warning (yellow Warning LED on)
A warning is an indication of a defined state. Warning indications can occur during normal operation; they may
be purely informative (uncritical) or indicate a potential problem. Analyse the warning based on the displayed
warning number [Wxxx].
Alarm (red Alarm LED blinks)
Alarm indications occur when motor operation has been inhibited by the FC 200 for safety reasons. Analyse
the alarm based on the displayed alarm number [Axxx]. There are several ways to reset alarms that are „trip-
locked“ after the cause has been remedied:
- [Reset] button on LCP
- Programmed digital input (see parameter settings in group 5-1*)
- Automatic reset function (see parameter settings in group 14-2*)
- Reset signal via bus interface (such as RS-485 or Profibus)
The reset signal resets the frequency converter after an alarm (trip). The button can be enabled [1] or disabled [0] with
parameter 0-43, “LCP Reset button”.
Warning
Before resetting an alarm, always determine and remedy the cause. Resetting an alarm without adequately determining the cause can
lead to damage to the frequency converter or system as well as serious accidents.
