Alarm Log

In General
Whether an alarm will activate a shutdown will depend on the type of alarm. A distinction is made between A alarms and B alarms, where A alarms activate a shutdown.

Alarms
List of current alarms in the system:

Red alarm text indicates A alarms
Blue alarm text indicates B alarms
Press Cancel alarms to acknowledge alarms. The list and the active alarms which are still active are restored and displayed.

Frequently Asked Questions (FAQ)

How do I acknowledge and cancel alarms?
To acknowledge alarms, press the ‘Cancel alarms’ button. This will restore the list and display the active alarms.
What do the different alarm text colors indicate?
Red alarm text indicates A alarms that activate a shutdown, while blue alarm text indicates B alarms that do not activate a shutdown.

Alarm log

In general

The parameters in the menu Alarm log are used to log alarms and operating data which have occur-red since the last startup of the VEX unit. A log is kept of which alarms have occurred, which alarms are nearing their limit values and operating data history. The logged alarms can be reviewed via the web user interface or the HMI Touch control panel/manual terminal. Apart from current alarms, the on-line user interface also shows impending alarms and the logged operating data. For a more detailed description of the parameters, see under: User > Alarm & log.
