3.2 Warning messages
If a warning is activated, a problem needs to be corrected, but the unit continues to work. If a warning message
is displayed in the PLC display, the light in the Standby/Running button flashes one second on, one second off.
This 1/1 on/off sequence continues until the problem is corrected. The backlight colour in the display changes
from white to amber while there is an active warning.
There are two exceptions to this rule,
Section 3.2.1 Time For service and Section 3.2.4 Bag Replacement Switch
Activated .
3.2.1 Time For service
The time interval set in the ‘Service Interval Setting’ menu has expired. If this warning is activated, the light in
the Standby/Running button is lit one second and then again in 7 seconds. This 1/7 on/off sequence continues
until the warning is reset.
Reset the alarm by first putting the unit into Off mode. Restart the unit. In Standby mode, press the manual fil-
ter cleaning button for 10 seconds.

3.2.2 Warning! Main Filter Clogged
This Warning is only shown when the Main Filter Delta Pressure Switch (MFDPS) is installed. This message is dis-
played if the Differential Pressure switch “DP switch” is installed and the Dp switch detects a high differential
pressure across the filter.
When the Dp switch detects a high Dp pressure, it activates a timer, which is shown in the display. If the Dp pres-
sure is still high when the timer elapses, the vacuum unit will stop and the alarm message “Alarm! Main Filter
Clogged” is activated.
