12.1 Types of alarms
The k.Air controller manages three types of alarms, depending on the reset mode:
• automatic: the alarm is reset and the unit restarts automatically when the alarm condition is no longer present;
• semi- automatic: if the alarm occurs several times, reset becomes manual and an operator needs to physically restart the unit;
• manual: an operator needs to physically restart the unit.
When an alarm occurs:
• pGDE: the Alarm button fl ashes and the display continues to show the standard view;
• th-Tune (if unit ON): the icons at the bottom of the display fl ash (see the Alarm table);
• pGDX: a red number is shown at the top right, next to the alarm icon, which indicates the number of active alarms.
• The alarm relays are activated on the digital outputs.
If the alarm is reset automatically, the Alarm button (pGDE)/icons on the display (th- Tune)/alarm signal (pGDX) goes off , the
alarm code is cleared from the list and the alarm reset event is recorded in the alarm log.
