Monitoring
8.5.1 Messages
All monitoring and protective functions trigger warnings or alerts. These are
signalled via the amber or red LED. A flashing message is output in the last line of
the control panel display.
If more than one message is output, the last one is displayed.
Alerts have priority over warnings.
Table 17: Function keys
To diplay current messages, choose the Diagnosis menu and then
2-2-1 (warnings) or 2-3-1 (alerts).
Active warnings and alerts can also be connected to the relay outputs. (
8.5.2 Resetting and acknowledging alerts
You can acknowledge alerts once the cause has been rectified. Alerts can be
acknowledged individually in the alert list in the Diagnosis menu under 2-1 . When
the system is reset, this causes all the alerts to be reset too. The reset can be carried
out via the control panel using the OK key (only possible in the main menu). You may
have to press the ESC key several times to return to the main menu.
The reset can also be carried out via a digital input. Digital input 5 is defaulted for
this purpose.
NOTE
Resetting alerts may cause the system to re-start.
By making the appropriate settings at parameter 3-11-2-1, Trip Reset Mode, alerts
can also be reset automatically. This parameter is defaulted to the automatic reset.
NOTE
The motor will restart after an automatic fault reset.
8.5.3 Alert history
You can display the alert history in the Diagnosis menu under
2-1-1.
The last few alerts are listed here.
OK
You can use the navigation keys and the OK key to select an entry
from the list.
Information about when the alert has come and gone is then
displayed.
