Note: This menu is divided into 8 sections for defining the user alarms UA1…UA8.
P21.n.01
- This defines the digital input or internal variable the activation of which generates the user alarm.
P21.n.02
- Channel number referred to the previous parameter.
P21.n.03
- Free text which will appear in the alarm window.
P21.n.04-P21.n.05-P21.n.06
- This defines whether one or more line breakers must be open when a user alarm occurs.
Example of application: User alarm UA3 must be generated by the closing of the input INP5 and must show the ‘Doors open’ message without opening any breaker.
In the case, set menu section 3 (for alarm UA3):
P21.3.01 = INPx
P21.3.02 = 5
P21.3.03 = ‘Doors open’
P21.3.04, P21.3.05, P21.3.06 = OFF
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.
