A situation may rarely (or even never) happen when an alarm does not need to be classified as such. This could happen if the "temperature sensors set" option is accidentally enabled for an object. ATM Monitoring displays an alarm "Temperature sensors off", indicating that the device does not work. After the "temperature sensors set" option is disabled for the object, the alarm in ATM Monitoring does not end.

This discrepancy can be fixed by clicking the  button (Close error forcibly). A list of the errors closed in this way can be seen by clicking the  button (Show closed errors). An additional table is shown on the right.

Left-clicking an entry in the alarm situation display area twice opens a dialog box, which explains the errors in the period of time described by the cell.

Left-clicking an entry in the reference information area twice opens a dialog box, which contains a full description of object properties.
