a report for example) is described below in paragraph 2.3.

Alarms
•
When alarms are triggered, the
icon flashes alternately red and green. Click on it to access the
alarms log. In the example below (Figure 12), we have simulated the failure of the energy meter for
a bulb stage. The log displays an alarm on the UV bulbs of level 2 (fault no.9) and instantly
determines that the failure is linked to the energy meter (fault no.18). Following this, we stopped
the R4000 to simulate a repair and the “machine stopped fault” appeared (fault no.19).

Start-up and shutdown procedure
•
Return to the main screen to start up the R4000. Click on the
green “
ON
”
button at the bottom left
of the screen. The machine starts up and the button changes colour. It is displayed in red with the
word “
STOP
”
. The fan starts up gradually until it reaches the requested flow rate and stabilises.
When the UV bulbs start up they will be displayed in yellow.
