ALARM OR SIGNAL EVENTS

First of all, a distinction should be made between three types of event:
•
Warning: This event does not stop anything but, if the condition continues, it could generate an Alarm event. The alarm cumulative does not need to be set.
•
Signal: event that does not stop anything and does not compromise the unit operation. It helps to set the alarm cumulative.
•
Alarm: Event blocking a device or the whole unit. It helps to set the alarm cumulative.
In case of an event:
• The red led flashes intermittently in case of a Signal.
•
The red led is fixed in case of an Alarm event.
• The main mask lights up.
•
The area 2 in the main mask displays the alarm icon, represented by an operating buzzer.
• The area 3 of the main mask displays an icon reporting the cause of the alarm and, next to it, the type of event (Signal/Alarm) and the associated event code.
By pressing the [ALARM] key once, the event detail mask appears. This mask provides the following information:
•
Event type (Signal/Alarm).
•
Event code.
•
Rearm type (Manual/Automatic).
•
Event position (Compressor/Circuit/Unit/System).
•
Action type (Compressor/Circuit/Unit/Water Circuit/Heater/Humidifier/Specific Function Block).
•
Event description.
The event reset is done by pressing the [ALARM] key on the event masks. If the [ESC] key is pressed, there is no reset and the event stays active.
For the event type details, refer to the table in the "Event Table" section of the "User interface" chapter.
Under the "Safety" menu, accessible through the "Factory" password, it is possible to modify the alarm cut-in times relative to air flow, exceeded limits, clogged filter
signalling and low pressure alarm, compatibly with unit configuration.
