The following sections show the different status, warning, and alarm messages that can be seen in the PLC dis-
play.
3.1Status messages
The following status messages give information about what mode the unit is in or what routine service is being
performed. See Figure1 for a chart that shows how FlexPAK moves between different unit modes.
3.1.1 Nederman FlexPAK Off (Off mode)
The unit is in Off mode, which is also the unit’s start menu. The unit can also go into Off mode if something is
wrong, such as if an alarm is activated. The pump motor is off, there is no vacuum, the Filter Cleaning Valve
(FCV) is closed, and the unit cannot be activated by a pilot signal.

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.

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.

If this message appears in the display, one or more emergency stops have been activated and the machine has
been switched off. External systems can be connected to the FlexPAK E-stop circuit, eg On the FlexPAK DX unit.
RPS panel sensor is connected.
Find out why the emergency stop has been activated and correct the problem. When all hazards have been elim-
inated that activated the emergency stop, the emergency stop can be reset. Reset the Emergency Stop Button
by turning it and then pulling it outward.
When all emergency stops have been reset, the security circuit can be reset by pressing the green OK button in
the display.
If the Green OK button can not be reset even though all emergency stops are reset, it may be due to a short cir-
