Alarms
When an alarm occurs, an alarm icon will appear on the display together with an ID code and the description of the alarm in the selected language.
If the page navigation buttons are pressed, the pop-up window with the alarm indications momentarily disappear and then reappear after a few seconds.
The red LED next to the alarm icon on the front panel will blink for as long as an alarm is active. If enabled, the local and remote acoustic alarms are
activated.
The alarms can be reset by pressing the OFF button.
If the alarm is not reset, it means that its cause persists.
If one or more alarms occur, the behaviour of the ATL6.. will depend on the alarm property setting.
Alarm properties
Various properties can be assigned to each alarm, including the user alarms (User Alarms, Uax):
Enabled alarm – General alarm enable. If not enabled, it is as if it does not exist.
AUT only – The alarm may only be generated when ATL is in automatic mode.
Retaining alarm – This remains stored even if its cause was removed.
Global alarm A – This activates the outputs assigned to this function.
Global alarm B – This activates the outputs assigned to this function.
Block BRK1 – controls are no longer sent to breaker BRK1 when the alarm occurs.
Block BRK2 – as above referred to breaker BRK2.
Siren – Activates the output assigned to this function as configured in the alarms table.
Inhibit – The alarm may be temporarily deactivated by activating a programmable input with the alarm inhibit function.
Modem – The alarm will be sent via modem (SMS or FTP).
No LCD – The alarm is normally managed but not shown on the display.
