2.1 General
WARNING! High vacuum.
A high vacuum system creates a powerful sucon that may cause serious eye injury or
hearing impairment. Persons who will be using FlexPAK 800/1000, or may come in contact
with FlexPAK 800/1000, are to be informed about this risk.
WARNING! Risk of personal injuries.
Never look into the exhaust air duct. Debris and parcles coming out of the outlet may
cause eye injuries.
WARNING! Risk of electric shock.
Personnel operang FlexPAK 800/1000 need to pay special aenon to avoiding discharge
of stac electricity.
NOTE! Only authorized personnel are allowed to have access to this unit.
3 PLC messages
The following secons show the dierent status, warning and alarm messages that can be
seen in the PLC display.
3.1 Status messages
The following status messages give informaon about what mode the unit is in or what

3.2 Warning messages
If a warning is acvated, there is a problem that needs to be corrected, but the unit
connues to work. If a warning message is displayed in the PLC display, the light in the
Standby/Running buon ashes one second on, one second o. This 1/1 on/o sequence
connues unl the problem is corrected.
There are two excepons to this rule, Secons ‘10.3.1 Time For service’ and
‘3.2.4 Bag Replacement Switch Acvated’.
3.2.1 Time For service
The me interval set in the ‘Service Interval Seng’ menu has expired. If this warning is
acvated, the light in the Standby/Running buon is lit one second and then again in 7
seconds. This 1/7 on/o sequence connues unl the warning is reset.
Reset the alarm by rst pung the unit into O mode. Restart the unit. In Standby mode,
press the manual lter cleaning buon 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 displayed if the Dierenal Pressure switch “DP switch” is
installed and the Dp switch detects a high dierenal pressure across the lter.
When the Dp switch detects a high Dp pressure, it acvates a mer, which is shown in the
display. If the Dp pressure is sll high when the mer elapses, the vacuum unit will stop and
the alarm message “Alarm! Main Filter Clogged” is acvated.
