product but not to personnel, and how that
hazard may be avoided.
NOTE!
Notes contain other information that is import-
ant for personnel.
3Description
WARNING!Risk of personal injury
See the User Manual.
4Unit Operation
4.1Software with extended functional-
ity
L-PAK 150/250 Advanced comes with extended soft-
ware and a standard Logo! PLC display that allows a
technician to easily set parameters and read status
messages.
NOTE!
If the software is used in a logo without a dis-
play, it is not possible to change parameter set-
tings.
4.2Unit operation modes
L-PAK 150/250 Advanced has the following four oper-
ation modes:
1 Off mode
2 Standby mode
3 Running mode
4 Idling mode
See Section5.1Status messages for more information
about each mode. How the unit moves from one op-
eration mode to another is explained below. See also
Figure 1 for a flow chart showing how the unit goes
through its four different operation modes.
When the unit is in Off mode, the unit can be put in-
to Standby mode (the unit is ready) with its motor off
and the Filter Cleaning Valve (FCV) closed by press-
ing the Standby/Running button. While the unit is in
Standby mode, the unit can be put back into Off mode
again by pressing the Standby/Running button.
NOTE!
If power is lost to the unit, for example, if there
is a power outage, and Zero voltage detection
is set to OFF, see Section .2.3ZV-Detect, the
unit goes immediately back into Standby mode
once power is resumed without having to push
the Standby/Running button.
The unit goes from Standby mode into Running
mode when it receives a pilot signal by a valve being
opened at one or more work stations (in other words,
someone starts to work). The unit’s motor is now on
and the FCV is closed. The DIR_Time and SSR_Time
timers are not started, see Section .2.5DIR_Time and
Section .2.4SSR_Time.
The unit stays in Running mode as long as there is an
active pilot signal. However, the unit can still be put
into Off mode by pressing the Standby/ Running but-
ton.
Note that if only one workstation is connected to
the unit, or if only one workstation is in use and work
stops at that one station, the pilot signal stops. If
there is more than one work station connected to the
unit, and more than one work station is in use, the pi-

L-PAK 150/250 Advanced
lot signal only stops if work stops at all workstations
(in other words, all valves close).
When the pilot signal stops, the DIR and SSR timers
start. If work resumes at one or more work stations
within 10 seconds, the unit stays in Running mode.
The DIR and SSR timers are reset back to zero and are
stopped.
If DIR_Time is set for 10 seconds (default), and the
pause in work is longer than 10 seconds, DIR_Time
elapses. The unit then goes into Idling mode with its
motor on and the FCV open.
If a new pilot signal is sent within 12 minutes, the unit
goes back into Running mode. The DIR and SSR timers
are again reset to zero and are stopped. However,
if SSR_Time is set for 12 minutes, which is the de-
fault setting, and there is no new pilot signal within 12
minutes, SSR_Time also elapses.
The unit then goes into Standby mode until it either
receives a new pilot signal that puts the unit back
into Running mode, or the unit is turned off (in oth-
er words, put into Off mode) by the weekly timer,
see Section .2. Weekly timer, or by pressing the
Standby/Running button.
5PLC messages
The following sections show the different status, warning and alarm messages that can be seen in the PLC dis-
play.
5.1Status messages
The following status messages give information about what mode the unit is in or what routine service is being
performed.

When the timer stops the unit and a valve at a workstation is in its open position, the unit will start imme-
diately once the timer puts the unit in standby mode.
It is not necessary to use the timer function. The function can be switched off by setting the display to show
only dashes. However, it is recommended that the timer function is used, as this ensures that the unit is
switched off even when a valve remains open, for example, overnight.
NOTE!
If the weekly timer has been activated, the amount of time the unit can be used during the day before it
automatically goes into Off mode can be extended if the optional external standby button accessory is
used, see Section .2.7OTTmr.

Standard Pilot Signal input Terminal 13-14 is now configurable.
When the input is activated, the unit starts as usual but depends on the setting below for filter cleaning. Filter
cleaning can be done during the running mode.
Standard input
Switch = Off: It is possible to activate filter cleaning any time when the motor is running by either timer or by
manual cleaning.
PSIFC input
Switch = On: Cleaning process cannot be activated by the timer or by manual cleaning. Cleaning starts after PS =
off.

6.2.10Clean cycle
Menu for setting the opening and closing times for the “FCV” Filter Cleaning Valve.
FCV cleaning cycle repeats X times depending on the value of parameter ‘On’.
This function is always active when filter cleaning takes place.
ESC OK
Clean Cyc 1/1
Tch = 05:00s
Tpu = 01:00s
On = 3
Cnt = 0
Tch = Vacuum Building time (Charge Time): Default is 5 seconds.
Tpu = Clean pulse time. Default is 1 second.
On = Number of cleaning pulses. Default is 3 pulses.
Cnt = 0: Elapsed cleaning pulses.
NOTE!
For the parameter ‘On’, the minimum value = 1.
NOTE!
If On is set to 0, No filter cleaning is performed.
Time duration for a cleaning cycle below:
Example: 1 Cleaning pulse
On=1, Tch=5, Tpu=1 → On * (Tch + Tpu) = 1*(5+1) = s where Tch=05:00s and Tpu=01:00s.
The default time for a complete cleaning cycle is seconds.
Example: 2 Cleaning pulses
On=2, Tch=5, Tpu=1 → On * (Tch + Tpu) = 2*(5+1) =12s where Tch=05:00s and Tpu=01:00s.
The default time for a complete cleaning cycle is 12 seconds
6.3Standard cleaning process
The filter cleaning process is always activated after the pilot signal (PS) or (PSIFC) has disappeared and DIR Time
has elapsed.
The filter cleaning valve opens and the filter cleaning process generates a preset number of cleaning pulses.
The unit then goes into Idle mode keeping the cleaning valve open.
See function in Section .2.10Clean cycle to set numbers of pulses and related parameters.
See function in Section .2.9FCTmr to activate Timer controlled Filter cleaning.
The Filter cleaning process can be interrupted by Pilot Signal Interlocking functions, PSIFC = Pilot Signal Inter-
locking Filter Cleaning.
See Section .4Standard Pilot Signal (PS) input.

6.4.1PS Input 2
Input 2, terminals 13 and 14 are for the standard pilot signal input. It is possible to set this input into 2 state
Standard or PSIFC mode.
Standard mode
Switch = Off: Filter cleaning by timer or manual cleaning is possible any time when PS is activated.
PSIFC mode
Switch = On: Filter cleaning by timer or manual cleaning is not possible when PS is activated.
Cleaning starts after PS = off.

6.4.2PS Input 8
Default Advanced PSIFC (Pilot Signal Interlock Filter Cleaning)
L-PAK Advanced models are configured with Input 8 as a pilot signal input for the PSIFC filter cleaning process.
Input 8, terminals 11 and 17 act as pilot signal inputs and interlock the cleaning process. When this input is used
as a pilot signal input, filter cleaning cannot be activated until this PS input is deactivated. If this input activates
during a filter cleaning sequence, the filter sequence stops immediately and the unit establishes a vacuum.
Input 8 can be combined with input 2.
Example: Input 2 = (PSIFC-I2 = Off)
When PS Input 2 is used the filter cleaning can proceed any time but if Input 8 is activated the input will interlock
all filter cleaning attempts “Input 8 has the highest priority”.
6.5Warning-Alarm output Q4
Potential free output Terminal X1:33-34.
When an alarm is activated, Output Q4 and White lamp button on the control box side flash with interval 1
second on / 1 second off.
Warning -Alarm Output Q4, switch with an interval 1 second on / 1 second off if one or more of the alarms listed
below are active:
• The fan temperature is over 125°C, see Section5.3.1Alarm! Fan Hi-Temp.
• The motor is overheated, see Section5.3.2Alarm! Motor Protector Activated.
• The compressed air level is low, see Section5.3.3Alarm! Low-Pressure CAS.
Warning -Alarm Output Q4, switch with an interval 1 second on /3 seconds off if one or more of the warnings lis-
ted below are active:
• Warning Fan Hi-Temp, see Section5.2.2Warning! Fan Hi-Temp.

The H1 lamp/Output DO1 acts as a Standby (unit ready) indicator. The H1 Lamp/DO1 is activated when the unit
is in Standby mode or the fan is running. The H1 lamp/Output DO1 is available on terminals X1:3 and X1:4 for re-
mote indication.
