Open Autosampler Components
Dynamic Load and Wash (DLW)
This section contains an overview of the Dynamic Load and Wash (DLW) option.
Figure 2.
Dynamic Load and Wash (DLW)
The DLW option represents a new wash station concept that combines an injection cycle with
wash steps. The linked combination of the two steps, which are usually separate, minimizes
cycle time and carryover.
There are two characterizing features for the DLW option:
• The sample solution never contacts the syringe itself; it is held between the holding loop.
• Wash solvents are pumped from back to front into the DLW system to intensely flush all
critical parts that are in contact with the sample.
The DLW option consists of two self-priming micro pumps (mounted on a dedicated
bracket), and the wetted parts are Ryton™ PPS and Kalrez™ (FFPM). The pump IN ports are
connected to the wash solvent bottles and the OUT ports are connected to the DLW
manifold, which is part of the assembly of the dedicated DLW syringe holder. A holding loop
separates the syringe and the DLW actuator to avoid sample from contacting these parts. For a
detailed list of the DLW components, see “DLW-2 components” on page 14.

Introduction
Open Autosampler Components
The syringe and holding loop are preloaded with wash solvent #1 at the start. The sample is
picked up and remains separated from wash solvent #1 by an air gap. After loading the loop
and injection, wash solvent #1 is pushed into the system, followed directly by wash solvent #2
to flush the critical valve paths.
The DLW syringe assembly is moved to the wash station for further cleaning steps and for
preparing the Syringe and holding loop for the next cycle.
For further details, see “DLW Cycle Step-By-Step” on page 96.
There has been continuous development on the DLW option. The current version, DLW-2,
has the following improvements over the DLW option:
• Holding Loop
The DLW-2 Holding Loop consists of one single piece from the needle to the loop, which
eliminates several tube connections and replaces the needle and flow diverter. The
Holding Loop is made of high-quality stainless steel and the inner surface is passivated
with acid.
• DLW Syringe Holder back plate
The DLW-2 Syringe Holder back plate has changed in size and form to allow a
replacement of the Holding Loop. The Actuator is supported fromt the back side to
provide higher mechanical stability.
• DLW Pump Assembly
The DLW-2 Pump Assembly is equipped with a housing to protect the electrical parts
from solvent splashes.

Installing the DLW
This section provides instructions on installing the various parts of the DLW option.
Installing the DLW Wash Station
You can connect the DLW Wash Station anywhere along the x axis. However, Thermo Fisher
Scientific strongly recommends that you install it as close as possible to the injection valve.
Make the travel path of the injection unit from the valve to the wash station as short as
possible to keep the cycle time as brief as possible.
Figure 21 shows two configurations for installing DLW modules, favoring a short connection
from the injection valve to the other HPLC system components on the one hand, and always
having the DLW Wash Station close to the injection valve on the other. Always attach the
DLW Pump Module, with the connected DLW tubing from the kit, on the far left side of the
x axis.
Such a configuration also has the advantage that you can connect the waste tube from the
injection valve to the front waste inlet of the wash station module. This waste tube is part of
the DLW option kit.

 To install the DLW Wash Station
1. Locate the DLW Wash Station module.
2. Attach the holder to the x axis at the selected position as shown in Figure 17.
3. Connect the waste from the injection valve to the DLW Wash Station.
4. Connect the waste tube to the wash station waste adapter.
Replace the dummy plug or plugs on the front if you are using them to connect the waste line
coming from the injection valve. This simple connection of waste lines cleans up the system,
avoiding several waste lines running to the waste container.
Tip Use the other two dummy plugs underneath the waste block for the DLW option.
You can connect the DLW tubing from the DLW pump outlet at these wash station inlet
ports. The functionality of the fast wash station is then applied using this configuration.

Figure 22. Attaching the DLW Wash Station to the x axis
Tip The waste tube must be positioned below the injection valve. Make sure that the
waste liquid flows into the waste container without restriction. The waste tube must
always be above the liquid level in the waste container.
Installing the DLW Syringe Holder Assembly
Tip Before you insert a syringe, first verify the position, Change Syr. Do not locate the
Change Syringe position above an object where the needle could collide with a vial, for
example.
Path: Menu > Utilitites > Syringe > function key F3 (Change Pos).
Move the PAL injection unit to a location where no collision can occur with the z axis by
selecting the x and y axes appropriately. The value for the z axis is given as a default and a
change of this position is not necessary in standard operation.
This precaution helps avoid needle damage during routine operation. Nevertheless, the
description in the next section on how to install the DLW Syringe assembly recommends
switching off the unit and inserting the assembly without using the Open Autosampler
command, Change Syringe.
The DLW Syringe Holder differs from standard liquid syringe holders. The DLW manifold is
attached to the syringe holder. The DLW Actuator/Solenoid and the Holding Loop
connecting the syringe inlet (bottom) and Syringe Needle are attached to the DLW manifold.
All of these parts are factory installed. See Figure 23.

Connecting the DLW Tubing to the Syringe Holder
Note Thermo Fisher Scientific recommends connecting the DLW tubing from the kit to
the syringe holder while the assembly is not inserted in the x axis.
Note The wetted parts of the DLW Actuator/Solenoid are PEEK for the body and FFKM
(Simriz) for the seal material.
PEEK tubing exhibits excellent chemical resistance to most of the chemicals used.
However, the following solvents are not recommended for use with PEEK: DMSO, THF,
methylene chloride (dichloromethane), nitric acid, or sulfuric acid. For more details, refer
to the compatibility tables provided by the manufacturer of PEEK material or
components.
 To connect the DLW tubing to the syringe holder
1. Connect the end of the sleeved tubing with the short tubes to the DLW Syringe Holder
assembly. See “Mounting the Pump Holder ” on page 24.
2. Use the groove in the block at the back of the DLW Manifold to orient the guide wire. To
connect, use the provided screw (M3×5) and the corresponding serrated lock washer.
3. Test to see if the wire tension is enough to keep the tubing in an upright position but low
enough to move the syringe holder manually along the x axis.
Note The design of the DLW Manifold and the concept of washing by active
pumping and active closing of the lines by the DLW Actuator theoretically do not
require a predefined solvent line position.
A problem could occur if solvent is refilled or exchanged while the tubing still
contains solvent from the previous setup. Always keep the lines at the same position,
and prime the entire system with caution to prevent unnecessary confusion. For
further details, see Chapter 5, “Operating Dynamic Load and Wash (DLW).”
4. Connect solvent line 1 to the upper port and solvent line 2 to the lower port at the left
side of the DLW Manifold.
Make sure the order of the tube connections, upper or lower, is consistent. In certain
applications you cannot mix types of solvents; for example, biofluid sample solution
should not come in contact with highly concentrated organic solvents.

CAUTION Make sure the removable needle fits leak-tight to the syringe. A Teflon seal is
provided. When installing the seal, ensure that the hole is open and that no fuzzy (lint)
polymer material, which might clog the needle, is in the path. When slipping the Teflon
seal over the needle, pay attention to the sharp edges of the needle that can cut into the
polymer, which again might cause the needle to clog.
6. Move the lower needle guide carefully up and down to make sure that the needle tip does
not catch on the guide.

Injection Valve Plumbing and Connection to DLW Wash Station
 To plumb the injection valve and connect it to DLW Wash Station
1. Connect the injection valve waste line from port 2 (for example, the standard Cheminert
valve type), as shown in Figure 30, to the front waste port of the wash station.
Tip If you use two injection valves in the PAL configuration, connect the second
waste line to the lower front waste port of the DLW Wash Station. If you use only one
connector, apply a dummy plug to the second port on the wash station.
2. Place the waste tube from the DLW Wash Station into the waste container.
Tip You must position the waste container below the injection valve. Make sure that
the waste liquid flows into the waste container without restriction.

Electrical Connections for Single Injection Valve Setup
CAUTION Always power off the Open Autosampler before connecting or disconnecting
the DLW cable or any other accessory cables.
The electrical connection of the DLW option is identical for the PAL HTS-xt and the
HTC-xt models. Both models use the same board.
The diagram in Figure 31 shows an installation using the valve drive connected to the AUX
interface. If you use a serial or multiposition valve drive, see the diagrams for 2- or 4-injection

DLW Option Installation in Combination with 2- or 4- Injection Valves
You can combine the DLW option with Open Autosampler systems using a setup of 2- or
4-injection valves (see Figure 32). The concept of the DLW option is that the crucial parts of
the wash station are attached to the injection unit.

The sample is taken up into the Holding Loop, and the syringe is actually the prepared
reservoir for the following wash step after the loop filling and injection step.
Following this concept allows for more than one injection valve in the Open Autosampler
configuration. Neither a special setup nor additional modules are necessary to inject into and
clean one or more valves connected to the Open Autosampler system. As mentioned, the
crucial DLW parts are attached to the injection unit at any available position.
Electrical Connections for 2- or 4-Injection Valves
Connect the valve drives as shown in Figure 33.
Because you can only use the DLW option in combination with the PAL-xt systems, you must
connect the first cable from the PAL Interface MODBUS to the serial valve drive connector
A. Each drive is connected with daisy-chain cabling.
The last serial drive connector B remains open or unused. The interface MODBUS provides
the electrical current and interface logic.

Accela Open Autosampler Object Positions
This section contains information about Accela Open Autosampler object positions.
Defining Object Positions
Note Remove the syringe adapter from the injection unit before performing the following
steps.
The objective is to define the reference positions for all Accela Open Autosampler objects.
Make sure to properly mount the tray holders, valve drives, and wash station to the Accela
Open Autosampler x axis. The following describes how to teach the reference position for a
tray holder. The described procedure is common to all Accela Open Autosampler objects.
Thermo Scientific

Installing the Accela Open Autosampler
Accela Open Autosampler Object Positions
 To teach the reference position for a tray holder
1. Switch on the Accela Open Autosampler power supply.
2. Observe the keypad display. The model name, Accela Open Autosampler, appears along
with the software version number. The Job Queue menu screen then appears.
3. When the Job Queue menu appears, complete the following sequence (common to all
objects):
where the Named Tray Holder represents a predefined tray holder (for example, THldr1
or Stack1).
After selecting Named Tray Holder, the x, y , z positions associated with the object are
displayed (see Figure 44).
Figure 44. Menu screen object Tray Holder
4. Select Position X and press ENTER. The injection unit moves to the previously defined
x-axis position.
5. Rotate the outer knob to adjust the x-axis position to the tray holder reference position.
6. Press the inner knob to enter the Position X value.
7. Repeat step 4 through 6 for Position Y and Position Z.
If the F3 button (Move to Zero) is activated, the injection unit moves to the HOME
position.
8. Verify the defined x, y, z positions by pressing F1: Check Pos.

Installing the Accela Open Autosampler
Accela Open Autosampler Object Positions
The release of PAL firmware level 4.1.2 makes possible the correction of all three axes, x, y,
and z, in the firmware class tray. You can correct the inclination for a tilted tray in the
direction of the row, the column, or both. Teaching is possible in the Utilities section by using
the path: Menu > Utilities > Trays.
Description of Object Positions
This section contains a description of the object positions.
Tray Holders Stack or Stack Cooler with 3 or 6 Drawers
The reference position for a stack or stack cooler is identical. The reference position in the
case of a 3-drawer stack is a hole in the upper drawer and in a 6-drawer stack, in the second
drawer from the top (same height level), as shown in Figure 45.
Figure 45. Stack reference position
For the object stack/tray cooler, you must properly position the x, y, z axes in the Open
Autosampler system.
After x-, y-, z-axis positioning of stack cooler model 6DW or 12MT, add the following steps
to verify the correct installation of the module.
 To verify the correct installation of the module
1. Close the drawer manually.
Go to Menu > Setup > Objects > TrayHolders > corresponding device.
Press function key F1, Check Pos. The injection unit moves to the predefined position.
2. Open the bottom drawer manually.
3. Remember the z value. Turn the z axis all the way down to check that the black needle
guide of the injection unit fits neatly into the position hole of the drawer.
4. If the position is proper, turn the injection unit slider back to the original z value. Then
close the drawer.

5. If the position is off by one or two millimeters, compensate for any discrepancy in the x, y
position seen between the upper and lower drawer.
6. If the position is off by more than one or two millimeters, check the bracket attachment
of the module to the x axis carefully. If in doubt, loosen the claws again and reposition the
unit on the x axis.
If this action is not successful, check the x- to y-axis angle and the y- to z-axis angle. If one
of these angles is not 90°, make corrections.
Ensure also that the y axis runs parallel to the open drawer. If this is not the case, the
bracket alignment is probably out of square.
Note The y axis tolerance for the teaching point is limited to 129.4 mm (5.09 in.).
When defining the position of the stack cooler, make sure you stay within this tolerance
with the reference point at the top drawer.
CAUTION Do not use vials without a sealing cap or a microtiter- or deepwell-plate
without a plate seal. Vapor phase from organic solvents can be hazardous and flammable.
Acidic vapor phase can cause corrosion to critical mechanical parts.
Trays
Generally, you do not need to teach a tray position. The tray holder has a teaching position, as
described earlier. The firmware assigns a tray to the tray holder. The numbers (values) for the
relevant items are stored in the firmware object tray. To complete the combination of a tray
holder and a tray, you must assign the corresponding tray type to the tray.
The tray type contains the geometric data for the tray and information, such as how many
samples are in a row and a column in the tray. A tray type defines the pattern and sampling
sequence of the sample location within a tray.
Again, the tray is physically placed in the tray holder, the firmware assigns the tray to the tray
holder and the tray type to the tray. This is routine procedure as long as no special
circumstances intervene, such as customized trays or tray types.
PAL Firmware level 4.1.2 or later now makes a correction possible if the tray surface is not
exactly horizontal and planar but is inclined in one or more axes. The ability to make the
correction is standard at level 4.1.x. A dialog box opens the moment the tray has been checked
out at the corners to verify vial positions and heights. The following sections explain how to
correct a possible inclination.

Definition of a Tray Row and Column
The Accela Open Autosampler defines rows and columns by the order in which samples are
treated. A row is not associated with an x or y axis. Figure 47 provides a visual definition with
tray type VT54.

 To correct for inclination in x, y, or z axes
1. After selecting the Utilities function, Tray, verify whether the tray type assigned
corresponds to the tray placed into the tray holder. If so, check the vial positions at the
three corners of the tray. The F3 function key activates this.
A message box opens, displaying a note: Adjust offset X-, Y-, Z for Position 001.
2. Select OK to adjust all three axes perfectly by the top of the vial. This step is only valid for
position number 001. See Figure 48.
Figure 48. Message to adjust offset x,y,z for position 001
3. To check the next corner of the tray, activate the F3 function key again, for example, tray
type VT54, position 009.
The message that appears prompts you to correct a possible inclination of the row.
4. Select OK to adjust the three axes perfectly to match the vial top or, in case of a
well-plate, the top of the plate. See Figure 49.

5. To move to the next corner of the tray, activate the F3 function key for position 54 in the
example of tray type VT54.
You can correct a possible inclination of the tray column in the same manner as you did
with the first two corners. See Figure 50.
Figure 50. Message to adjust column inclination at the third tray corner position
The three corner points are now adjusted for a possible inclination of the tray in any axis.
Without further teaching, the Accela Open Autosampler interpolates a possible deviation
from an ideal axis position for the other vials, caused by variance from the horizontal.
Note For routine work using a standard vial, you do not need to compensate for a
possible inclination as long as the vial detection is within the Z-Tolerance range.
Wash Station: Wash1/Wash2 Reference Point
Figure 51 shows the Wash Station Wash1/Wash2 reference point.
Figure 51. Wash station Wash1/Wash2 reference point
For a fast wash station, the reference positions are the two holes in the wash vial caps (see

This section contains information about the injection valve.
Valve Drives and Valves – General Remarks
An Accela Open Autosampler can be equipped with one LC injection valve connected and
controlled through the auxiliary interface (AUX). If you need to configure more than one
valve, or if an auxiliary interface is occupied by another module, such as a dilutor, then
multiposition or serial valve drives are required. The serial valve drives are connected at
MODBUS interface.
Accela Open Autosampler is equipped with the control board APR Control-xt, which
provides two auxiliary interfaces, AUX1 and AUX2. You have the choice to connect one more
valve drive.
Injection Valve Flow Path
The six-port valves are connected to the detection system according to the flow paths as
shown in Figure 58.
Standard LC Injection Valve, Cheminert 6-Port
The standard LC injection valve is a six-port, two-way switching valve with a flat rotary plate
and has a special needle guide (see Figure 58).

Valve Needle Guide and Needle Seal
All valves are equipped with a special valve needle guide fitting. This fitting has a wide
diameter to connect with the syringe needle guide on the injection unit. The valve needle
guide also has a countersunk hole to facilitate insertion of the syringe needle into the injection
port.
Figure 59 shows an example of the setup with the standard valve, Cheminert type.
Figure 59. Valve needle guide and valve needle seal
The valve needle guide holds the needle seal. The needle seal, which is a short length of FEP
tubing, forms the seal around the syringe needle. A stainless steel ferrule is tightened around
the FEP sleeve to ensure a leak-proof fit.
 To ensure reproducible sample injection and minimize carryover
1. Properly install the valve needle guide and the valve needle seal.
2. Change the valve needle seal at regular intervals.
3. Set the needle penetration depth accurately (see “Injection Valve Reference Points” on
page 57).
To specify a maximum number of penetrations into the needle seal is not practical. You might
want to check the tightness of the seal daily or weekly when first using the Accela Open
Autosampler to gain experience with the specific use in the laboratory related to the
application.
62
Accela Open Autosampler Hardware Manual
Thermo Scientific
2
Installing the Accela Open Autosampler
Injection Valve
 To test the tightness of the seal
1. Take the needle seal out of the valve port.
2. Manually insert a syringe needle gauge 22 (or gauge 22S) from the top, down into the
tube, and past the sealing point of the ferrule.
3. If you observe a restriction, continue to use the needle seal. If not, replace the needle seal.
Interval to Replace Needle Seal
The interval to replace the needle seal depends on the number of penetrations. Consider these
two factors for the decision to replace the needle seal:
• Leak, seal not reliable
Remove the needle seal from the inlet port and insert a syringe manually with the
corresponding needle gauge (standard Gauge 22 OD 18/25 mm). Move the needle below
the seal point of the ferrule. If you do not observe resistance at this point, replace the
needle seal.
• Carryover
If you suspect any contamination of the needle seal with a compound, replace the needle
seal.
Contamination can occur if the sample solution is accidentally dispensed too fast into the
valve system. The restriction of valve and loop might cause backpressure, forcing the
sample solution into the inlet port of the valve.
Note PAL Firmware (level 2.4.x or later) provides a counter for the number of injections
performed using the PAL System. This counter monitors the valve switches and not the
number of penetrations into the injection port; for example, cleaning the valve requires an
extra penetration. You might want to monitor this counter in conjunction with the test for
the tightness of the needle seal as described above.
After running routinely for a few weeks, the warning limit for the inject counter gradually
becomes evident and will be a valuable tool in routine work.
Path:
Menu > Info > Maintenance > Inject Limit (Inject counts reflect the actual number of
injections.)

Inject Count
Monitors the number of injections. The number of injection valve
switches is a helpful tool for deciding on replacement parts for the
injector system. The actual number of injections (valve switches)
is displayed. If the counter reaches the set limit (Inject Limit), a
warning appears at the next start of a job (run) (Inject Limit). The
same counter is used for injector penetrations with a GC
technique.
Inject Limit
Sets an upper limit for the number of injections.
Note Counters for the plunger movement and injector penetrations are available with
PAL Firmware level 2.5.x or later.
Free Objects/Free Items
In addition to the core software, the PAL Firmware contains data for firmware objects. There
are different classes of Objects, such as Syringes, Trays, Tray Holders, and so on. Each class of
objects contains items. The items contain the actual data, such as x, y, z positions.
The data are stored in a flash memory backed up by a battery.
To optimize RAM and Flash memory use, the software has a reserved section of memory for
each of the Objects and Object Items.
The percentage shown in the Info section indicates how much of the reserved software space is
still available.

Communicating with the Computer
This section describes how the Accela Open Autosampler communicates with a computer.
The PAL System provides a serial communication protocol with a PC. The Accela Open
Autosampler system requires a dedicated APR Control-xt board and PAL Firmware level 4.1.x
or later.
The COM port settings are normally defined in:
Windows\Control Panel\Device Manager\Ports
Figure 67 shows the standard settings for the serial communication. Be aware that the
application (for example, PAL Loader software) does actively set the communication
parameters, and the baud rate is set for optimized use.

Installing Cycle Composer Macros or ICC Cycles
Used for the DLW Option
You can only operate the Open Autosampler DLW option in combination with PAL control
software, such as Thermo PAL driver for Xcalibur or Cycle Editor, for ICC interpretation in
another data handling system software.
For software control, three macros or three cycles are provided.
The first of three macros covers the initial and daily priming of the solvent lines and covers a
complete injection cycle, a second macro is used for Standard speed with optimized washing
possibilities, and the last for a Fast cycle for optimized throughput and less focus on carryover.
See Table 27.
For detailed descriptions of all macros (or cycles), see Table 27, Table 28, and Table 29.

Installing Cycle Composer Macros or ICC Cycles Used for the DLW Option
Installing the Thermo PAL Driver Macros or ICC Cycles
Installing the Thermo PAL Driver Macros or ICC Cycles
The Accela Open Autosampler is shipped with a CD-ROM containing various cycles for the
DLW option. Macros for the Xcalibur data system are installed by the LC Devices 2.5
installer.
Copy these macros to your Thermo PAL driver method folder or corresponding folder for
application within the integrated system.
 To copy cycles to your Cycle Composer
1. Navigate in Windows™ Explorer to the Thermo PAL driver folder. The usual folder
location is as follows:
drive:\Thermo\Instruments\LC Devices\ThermoPAL\PAL
2. If you wish to add the DLW option macros to an existing method folder, copy the macros
(*.pma) and the methods (*.pme) files from the DLW Option folder on the CD-ROM to
the method folder.
If the PAL System is integrated in a data system software that controls the PAL using the
Cycle Editor for PAL ICC interpretation (for example, Analyst, ChemStation, Empower,
EZChrom, MassLynx, Xcalibur), an ICC Cycle is used and not the Cycle Composer
Macro. The cycle extension is *.cyx.
Note You can convert a Cycle Composer macro to a cycle (extension *.cyx) by using the
Cycle Editor software. Conversion is available starting with Cycle Editor version 1.4.0.4.
Note The provided macros are written for standard injection valve drives, which are
controlled and activated through the AUX interface.
General Considerations
You must establish the duration of the wash steps for each configuration and application.
Consider factors such as the viscosity and surface tension of the individual wash solvent
composition and the backpressure of the system.
Be aware that a higher backpressure builds up if the valve bore size (standard valve bore
0.25 mm) or the installed loop internal diameter is lower. Standard loop internal diameter
(ID) for Thermo-defined loops with a volume of 5, 10, and 20 μL is 0.25 mm. The loop with
2 μL content volume has an ID of 0.125 mm.
Keep the tubing internal diameters of the tubing in line with the valve dimensions, loop ID,
and flow rate.

Contents
• Priming the Solvent Lines
• Location of Solvent and Waste Bottles
• Functionality of the DLW Option
• DLW Cycle Step-By-Step
Priming the Solvent Lines
Tip For trouble-free DLW operation, make sure the two solvent lines are free of air
bubbles at all times. If the solvent lines are being connected for the first time or during a
solvent change, you must prime the solvent lines properly until air bubbles are no longer
visible. For best results, use solvent degassing.
In order to make the initial and daily priming efficient and controllable, the Open
Autosampler comes with a Thermo PAL driver macro, or ICC cycle.
For information on macros, see “Installing Cycle Composer Macros or ICC Cycles Used for
the DLW Option” on page 85.
 To prime the solvent lines
1. Load the macros and methods into the folder.
2. Start the corresponding macro for initial or daily priming.
3. Check the solvent lines and prime until air bubbles are no longer visible.
4. Press F4 for Home.
Location of Solvent and Waste Bottles
The DLW option contains self-priming membrane pumps. The solvent bottles can be placed
either in the fast wash station holder or on the lab bench.
Thermo Scientific
Accela Open Autosampler Hardware Manual

5
Operating Dynamic Load and Wash (DLW)
Functionality of the DLW Option
You must place the Waste bottle greater than 30 cm (12 in.) below the injection valve. Make
sure that the waste liquid can flow into the waste bottle without restriction. Place the waste
tubing above the level of the liquid. Ideally, the tube is fixed at the neck of the waste bottle.
Tip Use good laboratory practice to avoid contaminating the wash solvents and the wash
bottles. Avoid biological growth in pure water by either replacing it regularly or adding a
small percentage of organic solvents, such as methanol or acetonitrile. Certain buffer
solutions can decompose at room temperature when exposed to light. Filtering the wash
solvents before filling the bottle, especially if using salt buffers, is mandatory to avoid any
clogging of the solvent paths.
Functionality of the DLW Option
This section contains information about the functionality of the DLW option, including the
DLW pumps and the DLW Actuator/Solenoid.
DLW Pumps
From the control viewpoint, the DLW pumps respond in the same manner as the fast wash
station. Power-out signals activate the pumps. Because the electric current setting for the
DLW is different, the corresponding PAL Firmware Objects must be loaded for the DLW
wash station type.
The wetted parts in the pump are made from the following materials:
• Membrane: Kalrez (FFPM)
• Body, valves: Ryton PPS
The pumps are self priming with a suction lift of up to a 3 m water column.
DLW Actuator/Solenoid
The DLW Actuator/Solenoid has the function of separating and completely shutting off the
lines in the direction of the syringe (sample loading) or the wash solvent lines.
After opening the DLW Actuator/Solenoid for the wash solvent lines, you can pump the
desired wash solvent into the system by activating the corresponding DLW pump.
Figure 68 illustrates this functionality.
The wetted parts in the DLW Actuator Solenoid are made from the following materials:
• Solenoid body: PEEK
• Seal material: FFKM (Simriz)

DLW Cycle Step-By-Step
Considerations for Additional Stator Wash Cleaning Step
The DLW Standard Cycle has the built-in option for the user to toggle the injection valve at
the end of the chromatographic run before equilibration of the column to the start
conditions.
If the method variable Stator Wash is set to 1, the extra cleaning process for the valve, using
the Valve Toggle, is part of the standard cycle.
If the method variable is deactivated (setting, 0), the DLW Standard cycle ends as shown in
Figure 83.
The macro (cycle) is written so that the optional valve toggle steps can be executed before
re-equilibration of the column. You must synchronize the time to switch the valve with the
chromatographic method using the method variable Delay Stator Wash. The two wash
solvents are timed by the method variables Stator Wash Time Solvent 1 and Stator Wash Time
Solvent 2. After these wash times have elapsed, the valve is switched back to the start position.
Figure 84 illustrates the recommended retention time for Stator Wash or Valve Toggle times.
Figure 84. Timing for Stator Wash step
From the chromatographic viewpoint, the optional cleaning step is important to understand.
Assuming that the valve stator between ports 1 and 6 (for example, a standard Cheminert
valve) is contaminated and cannot be cleaned during the injection process, the valve toggle
brings the engraving back between the two ports. Flushing the valve with both wash solvents
eliminates remaining sample material located between stator ports 1 and 6.
What points must you consider when you use the Stator Wash or Valve Toggle option?
Observe the rules if biofluid samples are injected. The first sample contact should always be
with an aqueous solution to avoid protein precipitation. After washing with organic solvent
(higher elution power), you must flush the system again with wash solvent 1.
The first toggle near the end of the chromatographic cycle provides the advantage that the
sample loop is already flushed out first with the mobile phase with a solvent of high elution
power (assuming gradient application).

Operating Dynamic Load and Wash (DLW)
DLW Cycle Step-By-Step
The second valve toggle time follows immediately after finishing the second solvent flush. You
cannot program a second switching time. The waiting time for the second valve toggle should
be long enough so that the entire system is flushed out by both wash solvents.
Consider the entire delay volume to determine the second valve switch. The DLW internal
volumes are as follows:
Manifold, 90 μL
Holding Loop,108 μL
Syringe Needle Gauge 22, 6.7 μL
Installed Injection Loop
Total delay volume: 205 μL + Loop content volume
Toggle the second valve (back to the starting condition) before the system equilibration time
has started. The loop content is ideally a solvent of a low elution power when switched back.
If isocratic chromatography is applied, the remaining contaminants might be washed into the
system and can build up higher background noise for the column, the detector, or both over a
longer period of time.

Temperature Control
As described in the Specifications section, the cooling/heating capacity of a temperature
control device based on the Peltier technique is always related to room temperature. Only a
limited maximum temperature difference from ambient temperature can be achieved.
PAL stack/tray cooler modules should reach a minimum difference of 14 °C (ΔT).
The controller provides the following temperature setting range:
• Stack cooler: +1 to 45 °C
• Tray cooler: +1 to 70 °C
This wider control range, which is greater than the specification limits (+4 to 40 °C and
+4 to 70 °C, respectively), provides cooling or heating when the ambient temperature is too
high or too low to easily reach the desired temperature. Heating to a higher temperature could
be important for metabolism or kinetics studies at the human body temperature level of
37 °C.
The cooling option is usually necessary to protect the sample from ambient temperature
during the analytical run time. Stack/tray cooler devices are rarely used to store a sample at a
given temperature for a longer time period.
The measured and displayed temperature represents the temperature in the compartment and
not in the sample liquid. To check the temperature control, an independent temperature
probe is inserted from the front by removing one plastic screw from the front cover. Position
the probe in the middle of the drawer where the tray separator projects up. Tape the probe to
the metal plate of the drawer.
To reach +4 °C in the analytical solution, program a set value lower than +4 °C. The material
used for the sample may be glass, polypropylene, polyethylene, or similar polymer products.
All of these have excellent insulating properties.

Operating the Temperature Controllable Stack Coolers
Temperature Stability
If the sample has to be cooled as low as +4 °C, cool the sample tray first in a refrigerator before
the tray is placed into a stack/tray cooler module. This shortens cool-down time considerably.
Temperature Alarm
An internal alarm point of 55 °C protects the upper limit of a stack cooler module; it is 72 °C
for a tray cooler. Reaching this point in a single fault situation causes the temperature control
unit to automatically force cooling to the fullest extent possible. (The alarm is not audible.) At
the same time a corresponding Error message is displayed. For explanations of these messages,
see “Cooled Stack Power Supply Error Messages” on page 141.
A fuse to prevent overheating is built in for unattended automated runs.
The Peltier element turns off automatically at +72 ± 5 °C.
Only an authorized representative of Thermo Fisher Scientific can replace a damaged
over-temperature fuse.
In case of error, do the following systematically:
1. Check the corresponding error message (see “Cooled Stack Power Supply Error Messages”
on page 141).
2. Verify whether the appropriate power supply is being used for the stack cooler and tray
cooler.
3. Turn off the power supply, wait a few minutes, and turn it on again.
Ensure that the alarm is off. If the alarm is still on, observe the corresponding error
message.
Temperature Stability
The stack/tray cooler is basically a thermostatted sample tray that keeps the analytical sample
below or above ambient temperature.
Thermo Fisher Scientific recommends the following guidelines:
• Switch on the stack/tray cooler at least 30 minutes before the analytical routine run is to
be started at +10 °C or 75 minutes, if operated at +4 °C.
• For high-throughput analysis–typical cycle time of 60 seconds or less per analysis–leave
the drawers open between injections.
• For longer cycle times, use the Accela Open Autosampler option to close the drawer after
each sampling.
You can change the Restore mode to keep the drawer open or closed during a run

Condensation Build-Up
This section contains information about condensation build-up in in stack coolers and tray
coolers.
Condensation Build-Up in Accela Open Autosampler Stack Coolers
Condensation build-up is directly related to the temperature and relative humidity/
temperature in ambient air (dew point). Long-term tests showed very little build-up of
condensation in an environment of relative humidity up to 60 % and 22 ± 2 °C ambient
temperature.
Condensation at the back of the compartments is channeled to the drain outlet labeled
Condensation Drain at the lower back portion of the stack cooler. The outlet is plugged with
a paper filter. This helps to evaporate the collected water in the drain line using the excess heat
from the Peltier element. A drain line from the outlet to a reservoir bottle is not necessary
under normal conditions.
CAUTION If a flush gas is used as described below, you are responsible for ensuring that a
two-stage safety pressure regulator device is installed between the gas supply and the stack
cooler.
Do not use any flammable or explosive gas such as hydrogen.
If you operate the stack cooler under severe conditions, you can use a flow of dry and clean
(oil-free) air or nitrogen to dry the compartments continually. Connect the corresponding gas
line to the Swagelok fitting (1/8 in.) at the back of the stack cooler DW labeled Flush Gas. A
flow of approximately 300 to 400 mL/min is required to keep the compartments
moisture-free.
If acidic vapor phase is anticipated due to the application, use the same gas line connection to
flush a stream of inert gas, such as nitrogen or helium, into the compartments. A stream of a
few mL/min can help to prevent corrosion of the rolls.

Operating the Temperature Controllable Stack Coolers
Condensation Build-Up
Thermo Fisher Scientific recommends checking regularly for condensation build-up. It is
good practice to clean the inside of the stack cooler when changing the analytical samples, dry
out the stack cooler at ambient temperature at regular intervals, and open the drawers 1 cm to
5 cm (0.5 in. to 2.0 in.) for air circulation. The compartment drying frequency depends
greatly on surrounding conditions.
Condensation Build-Up in PAL Tray Coolers
Condensation build-up is directly related to the temperature and relative humidity/
temperature in ambient air (dew point). Long term tests showed little build-up of
condensation in an environment of relative humidity up to 60 percent and 22 ± 2 °C ambient
temperature.
A built-in drain line, as installed in stack coolers, is not provided in a tray cooler.
It is also good practice to install the Plexiglass lid whenever possible to avoid condensation
build-up. You might not be able to install a lid for certain applications, for example, if a vial
has to be transported to an Agitator or a Barcode Reader. In certain situations, the height of
the vial is the limiting factor for installing a lid. Operating a tray cooler under less than
optimal conditions requires some on-site improvisation. A simple foil or lid with cut-outs for
the vials will limit condensation build-up dramatically.
Thermo Fisher Scientific recommends checking regularly for condensation build-up. Clean
the inside of the tray cooler when changing the analytical samples, and dry out the tray cooler
at ambient temperature at regular intervals.
Note For certain applications, a change from a tray cooler to Stack 2DW Cooler might be
indicated. As long as deep well, microtitier plates, or 2 mL vials (TrayType VT54) are
being handled, this change is positive with respect to condensation build-up. It would also
double the capacity of the trays.

Troubleshooting Considerations
This section contains information about special troubleshooting considerations, including
tubing connections and solvent delivery pumps not priming or not functioning.
Tubing Connections
You must pay special attention to all tubing connections, including these common mistakes in
routine practice:
• Nut and ferrule not connected leak tight (see Nut and Ferrule Tightening)
• Incorrect pilot distance (see Incorrect Pilot Distance)
• Tube not cut square (see Tube Not Cut Square)
• Wrong type of ferrule or nut used (see Wrong Nuts or Ferrules Used)
• Trapped air bubbles (see Avoiding Trapped Air Bubbles)

Troubleshooting Considerations
Figure 103 provides an illustration of the terms used for tubing connections.
Figure 103. Terms for tubing connections
Such mistakes lead to:
• Dead volume
• Peak deformation or peak splitting
• Carryover effects
• Decreased resolution of the tubing between column and detector
You can prevent issues with tubing connections by observing the following basic rules.
Nut and Ferrule Tightening
 To tighten a nut and ferrule stepwise
1. The first important rule when tightening a nut and ferrule is to proceed stepwise.
a. Tighten the nut by hand as much as possible.
b. Continue to tighten using a wrench until you feel resistance. Add one or two quarter
turns to reach the sealing point.
c. Open the connection and remove the assembly to inspect the pilot distance. See
Figure 103.
d. Install the assembly again and, first, manually tighten the nut. Then, use the wrench
to reach the same sealing or resistance point as reached in step 2 and add one quarter
turn extra for the final seal.
e. Check the seal when liquid is pumped through the system. In case a leak is observed,
tighten once more by another quarter turn. Always move from a leaking to a tight
seal; never move backward from an over-tightened seal.
Thermo Scientific
Accela Open Autosampler Hardware Manual
143
7
Troubleshooting
Troubleshooting Considerations
Do not over-tighten the nut/ferrule. If a connection proves to be leaky, use another
quarter turn to tighten. Step-by-step tightening is the correct approach. Over-tightening
even once will damage the seat, and the next connection can only be sealed using force. If
the seat is damaged, the ferrule will likely stick and require force or special tools (such as a
drill) to remove it.
If you use different materials, such as a polymer tubing and nut, together with a stainless
steel ferrule, then over-tightening is always a danger. The ferrule will bite into the
polymer tube and block the flow.
When installing a tube with a narrow bend, typically a loop, fix one connection first; do
not simultaneously insert the second nut into the female counterpart. After tightening
open the connection as described above, start preparing the second connection without
inserting the first nut. Open the second connection again and check the pilot distance.
The last step is inserting the complete tubing with the two connections and making a
final seal as described earlier.
This stepwise installation of a bended tube is mandatory for PEEKsil tubing (fused silica
tubing sheathed with PEEK polymer).
2. The second rule to observe when installing nuts and ferrules is to never reuse them for
any other connection.
Do not install a tube for any other application with a nut/ferrule that is set for a specific
purpose. Cut a portion of the tube end until straight tubing is reached and remove the
ferrule.
This rule is valid for a loop as well. Never reuse a loop for another valve or reuse a valve
after exchanging the stator.
If a finger-tight nut has been installed, replace it as well. If a stainless steel nut has been
used, ensure that you use the correct type.
Newly installed finger-tight ferrules can hold a backpressure of up to 200 bar.
Incorrect Pilot Distance
When making a new tube connection, be sure to follow these guidelines:
1. Slip the nut and ferrule over the tube. Make sure the end of the tube sticks out
approximately 50 mm (2 in.).
2. Press the tube end firmly into the female counterpart for the connection.
3. Move the nut and ferrule together into the female counterpart for the connection. Make
sure to maintain pressure on the tube to avoid the tube slipping backwards, out of
position.
4. Tighten the nut as described in the previous section.

Accela Open Autosampler Hardware Manual
Thermo Scientific
7 Troubleshooting
Troubleshooting Considerations
Figure 104. Pressing the tube into place
Failure to observe this procedure will lead to an incorrect pilot distance, which will result in
actual dead volume, not delay volume.
Tube Not Cut Square
All tubes have to be cut absolutely square. Any deviation from square causes a dead volume
which yields carryover and other chromatographic effects. This rule is valid for stainless steel,
PEEK, or Polymer tubing. The material is not decisive, but using the correct tool for each
material when cutting a tube is.
Stainless steel tubes are often cut by using pliers. Often, an egg-shaped profile results, which
no longer seals and causes dead volume. Dedicated pliers for HPLC tubing are available on
the market; nevertheless, for best results, use precut tubing which is cut smooth and clean,
and is passivated.
Because polymer tubes, such as PEEK, Teflon, PFA, and so on are soft, you might choose to
cut them with any handy tool. Commercially available tubing cutters from many
manufacturers are available. If the blade does not provide a clean, right-angle cut, however,
use a different technique.
The most reliable and common way to cut tubing of any material is with a cutter that has an
adjustable blade. Carry out the initial turns, readjust the blade, turn once more, and adjust
again until approximately half of the tubing wall is cut. Hold the tube on the two sides of the
cut with flat-nose pliers and twist the tube until it breaks. You can use the same procedure for
polymer tubing by replacing flat-nose pliers with tweezers with a flat tip.

Avoiding Trapped Air Bubbles
It is common practice to make a connection only if the ports are wetted. The liquid helps to
prevent trapped air bubbles, which are often tedious to remove or work out of a system.
Solvent Delivery Pumps Not Priming
The solvent delivery pumps of the Pump Module can fail to prime at initial operation.
You must wet the pump at the solvent inlet port or, preferably, prime the tubing from the
Solvent reservoir to the pump and make the connection.
Dry running the pump for a short time will not harm it.
Solvent Delivery Pump Not Functioning
The pump flow rate depends greatly on the viscosity of the selected wash solvent and the
given backpressure of the entire system. Consider the valve bore size (standard Cheminert
valve 0.25 mm), as well as the tubing and injection loop internal diameter.
If in doubt about the delivered volume of a pump, run the following test (Test 1). If the result
of the test is negative, check the flow from the pump directly (Test 2).
 (Test 1) To test the pump flow delivered throughout the entire system
1. Prepare a graduated cylinder with a volume of 10 or 20 mL.
2. Test a solvent, for example, water.
3. Select the path from the local terminal workstation.

4. Activate the pump by selecting this path:
Menu\F3-Setup\Objects\Events\Pwr-Out1 or Pwr-Out2
5. Collect the pumped water in a graduated cylinder.
Expected Result: Within 30 seconds, pump delivery of approximately 10 mL
This short test can indicate whether the system is performing as expected. If you observe no or
very little flow, systematically check using a process of elimination. For more details, see
Table 31.
Standard Chromatographic Tests
This section describes standard chromatographic tests for carryover and repeatability. These
tests provide basic information for both users and technical support.
The tests described are examples only; vary them accordingly if the configuration of the
HPLC system changes.
The first test uses PAL standard valves with a bore size of 0.25 mm to provide a flow rate
range of 10 to 500 μL/min.
Both tests, carryover and repeatability, test conditions for UV and LC/MS detection.
Details are listed in the next section. Note that the given levels to reach for carryover and
repeatability do not reflect the specification value. These described tests should give you
confirmation if the system is working to expectation using reasonable effort and time. The
tests are more comparable with an OQ Test (Operational Qualification Test).
Note The levels provided in these tests do not reflect the specification value for careover
or repeatability. The test results will confirm if the system is working properly with
reasonable effort and within the expected time frame. The tests are comparable to
Operational Qualification (OQ) tests.

Description
Cycle
The specific operations necessary to process one sample. The cycle
operations are repeated for each sample within a job. Cycles are
designed for specific applications.
Job
The information needed by the Accela Open Autosampler to process
multiple samples by the same processing steps. The elements of a job
are a method and a tray that define the location of the samples to be
processed. For identification, jobs are automatically numbered from
01 to 99 and then restart with 01 when they are added to the Job
Queue.
Job queue
A list of sample processing jobs. Jobs are executed in the order
displayed on the JOB QUEUE menu screens. You can add new jobs to
the queue while samples are being processed.

Terms
Description
Method
How the samples are processed. The elements of a method are a cycle,
a syringe, and a parameter list. Methods have names with up to eight
characters and can be edited, copied, and deleted.
Method
parameters
Associated with the cycle operations. User-assigned parameter values
define how a processing operation is performed.
A zero parameter value will disable a cycle operation. Cycle parameters
are application-specific.
Module
PAL hardware module, either part of a standard PAL configuration
(for example, Combi PAL, HTS PAL) or an optional addition (for
example, cooled stack, MALDI tool, dilutor).
The term Module is intentionally used to differentiate from object,
which is reserved for the PAL firmware object.
Objects
Data structures describing the properties of physical modules. Certain
modules (for example, a stack) require several objects.
Object class
Each object belongs to an object class (for example, syringes, trays,
injectors).
The object class defines the Items of an object.
Object Item
An object contains several Items, which can be numerical values with a
physical unit (for example, x-, y-, z-position, penetration, syringe scale
length, syringe volume) or references to other objects.
Note that the term, Parameter, is reserved for ATOM Parameter.
(PAL firmware commands are to be used for a PAL cycle or macro).
PAL Object list
If you add a PAL module (hardware) to an instrument, you must load
several objects into the firmware. These objects are collected in an
object list and stored in a file with the extension *.pol.
Object lists are delivered together with object manager software and
are grouped into folders for the different kind of modules (for
example, syringes, tray holders, valve drives). The name of an object
list starts with the module part number with variants added (for
example, first or second stack). The name of the root folder includes
the revision which depends on the firmware version (for example,
object lists Rev. K for firmware 2.x and 3.x).
PAL Object
Manager
170
Accela Open Autosampler Hardware Manual
Software to load a PAL object list to an instrument if a module

Description
Stack
A particular type of tray holder that is designed to hold microplates. A
six-drawer stack holds 12 standard microplates, two in each drawer.
A three-drawer stack holds six deep-well microplates, two in each
drawer.
Tray
Holds multiple samples. Trays are defined by designating the tray type
(see below) and the tray holder. Tray names are used to identify the
sample source within an autosampler job.
Tray holder
Holds one or more trays. Each tray holder has a reference position (x,
y, z coordinates) that defines its location.
Tray type
The pattern and sampling sequence of sample locations within a tray.
Naming Convention
This section recommends the standard naming convention for the Accela Open Autosampler.
Following this convention will allow the PAL setup to be preconfigured for certain
applications. This will simplify software backups and application development, and will
improve technical support and training.

Special Functions
This section describes special functions that you can activate by applying the Extended User
mode.
The purpose of having two software access levels is to display discrete items and sections of the
firmware at each level. Settings that you set rarely—perhaps at the time of the Accela Open
Autosampler system installation—are hidden at level 1 (User Level) and revealed at level 2
(Extended User Level). This also protects the Accela Autosampler in group use. Nevertheless,
you should become familiar with the important points as described.
Accessing Extended User Mode
Access the Extended User mode by the following path:
You can navigate to the Extended User mode in one of three ways:
• Choose Menu > Setup.
• Press the F3 function key.
• Activate Setup by pressing the center of the selector knob.

Accessing the PAL Firmware Class Objects in the Extended User
mode provides more detailed possibilities for object items. At this
level, you can copy or delete an Object by using the specific
function keys. This provides quick access to add, for example, a
second or third injector.
System
Select the particular item to change system settings.
PAL Firmware level 4.1.x adds an intermediate step. After selecting System, the new Settings
level follows. Activating Settings opens the described items in Table 44.
Table 44. System items (Sheet 1 of 3)
Item
Description
Syr Detect
Turns off the syringe detection if the sensor fails or if a special
syringe with unknown ID is installed. Turning the syringe
identification sensor off displays a dialog box for selecting a
syringe identification.
Start Ref
Provides the choice of referencing all axes at the start of the system
or suppressing the referencing. Use this function to detect a
possible loss of steps.
Stop XY Error
Turns off the automatic recovery of the PAL System after
detecting a collision (loss of steps of a stepper motor).
Stop XY Error = ON: Automated recovery turned OFF
Stop XY Error = OFF: Automated recovery turned ON
If recovery is turned off, the PAL System always checks its position
before moving to the injection port for injection. This can result
in an extra move, crossing over the x-y-axes sensors, if the injection
port is at the opposite end of the x axis relative to the sample
location, (zero x-axis position in between sample location and
injection port).
For critical application fields (for example, clinical analyses), turn
off the automated recovery; Stop XY Error= ON.

Description
PlgPathCheck
Monitors the plunger travel path to ensure that the plunger tip
reaches the syringe zero point in all cases as compared to the
original plunger referencing and defining the syringe zero point. If
an error is detected, the PAL System stops. This feature is useful if:
sample solutions with particles need to be handled, the syringe
type is not adequate for the solution composition, or the syringe
plunger is blocked or bent.
PlgChnge Pos
Changes a syringe using the Chnge Syr menu function and moves
the plunger up to the position specified by this item. For normal
use, accept the default values.
Init Syr at
Initializes the syringe plunger at the Home or Waste position.
If samples with a high danger of toxicity are treated, use the Waste
position for referencing.
Inj Signal
An autosampler is the master instrument in a chromatographic
system. The other components send a Ready signal to enable the
autosampler to start. At the moment of injection, the PAL System
sends a Start signal to the other components. The Inj Signal item
defines the status when the signal is sent. The syringe is filled with
the defined sample volume.
PlgUp = The Start signal is sent at the moment the plunger starts
moving down for injection.
PlgDown = The Start signal is sent at the moment the plunger
reaches zero point from syringe.
(Recommended for large volume injection, but not in
combination with Agilent Chemstation.)
ValveSw = The Start signal is sent at the moment the injection
valve is switched, HPLC technique.
PreInj = Start signal sent at a time before injection, as with a
sample preparation device started before a GC or LC system.
Minus time relative to chromatographic start time.

Description
Vial PrePress
Avoids a vacuum if a relatively large amount of sample is taken out
of a small volume vial. If, for example, a volume of 50 μL is
specified for injection, the PAL System first takes 50 μL of
ambient air and injects this volume into the sealed vial, and causes
overpressure in the vial. Then, the sample volume is aspirated
without forming a vacuum. This functionality is only valid for
liquid sampling, and not valid for the Headspace technique.
Starting with PAL Firmware level 4.1.x, this item is also active in
combination with Thermo PAL driver.

Tools
The object class Tools is used to handle another device, such as the
MHE-Tool (Multiple Headspace Extraction Tool) or
MALDI Tool.
Positions
The various positions used with the PAL System are selectable at
this level. Positions such as Home, Change Syringe, or a Path
Point, reference the Paths for a specified tray holder directly, such
as Agitator or Stack.
Selecting an item (for example, Home) enables the F1 function
key and displays Check Pos on the screen. Activating this function
provides the possibility of verifying x, y-, z-axes values for this
particular position.
Paths
A Path defines specific movements for the injection unit, which
represents a repetitive task assigned to a tray holder. Typical
examples are opening and closing a drawer from a Stack or
opening the lid of an Agitator.
The Path is composed of several steps (points) that are added up in
a sequence. Each individual step (point) can be positioned by
teaching x, y, z axes. In most cases the return path is in the reverse
order of the starting path, for example, AgiOpnL and AgiClsL. If
one setting of a point is changed, this change is valid for the return
path as well.

Motors
In the class Motors the object Motor-Y is accessible in order to
select the items Strategy and Path Speed.
Three different settings are selectable for the Y-Motor movement
strategy:
• Rectang = normal movement as used for PAL System.
(On firmware level < 4.1.x, this mode was called Auto.)
XY-Simul = x, y axes move simultaneously, which allow
movement in a diagonal direction.
(At firmware level < 4.1.x this mode was called Rectang, but it
was not active at lower levels.)
• Retract = y axis moves from any point first to zero Y (back to
the x axis) before the X-movement is started. This mode
allows bypassing an object (such as a large GC detector),
which might be in the travel path if using the default mode
Rectang.
• Path Speed = y-axis motor speed in conjunction with a Path,
example: Opening and closing a drawer of a Stack. In certain
situations you will need to slow down the speed to open and
close a drawer. A typical application example is fraction
collection, collecting directly into a well plate. If the liquid
level is high, the liquid can wash over into the next row if
drawer movement is too fast.
Remark: At PAL Firmware level 4.1.x, these items of the Y motor
have been made available at the Extended User Level.

PAL Firmware level 4.1.x and the APR Control-xt board.
Sample Volume
The current version of the DLW Option can handle sample volumes from 2 to 100 μL.
Wetted Parts and Material
Some components are not compatible with certain solvents or chemicals that are used in given
applications.
206
Accela Open Autosampler Hardware Manual
Thermo Scientific
A Appendix
Interfacing the Open Autosampler to Other Devices
Tubing Internal Diameter (ID) and System Backpressure
Any tubing and component in the flow path, such as an injection valve, will contribute to the
system backpressure. For example, short tubing with an 0.13 mm (0.005 in.) ID can build up
high backpressure when using standard wash pump flow rates.
The wash solvent pumps operate in the range of mL/min. Such a flow rate in combination
with a high system backpressure, caused by small ID tubing, will slow down the pump and, as
a result, the flow rate.
The described situation is only critical if you select an HPLC setup dedicated for nano flow.
Interfacing the Open Autosampler to Other Devices
This section contains information about interfacing the Open Autosampler to other devices.
Synchronization and Output Signals
Synchronization Signals (Sync Signals) are inputs that tell the Accela Open Autosampler
when to wait or proceed with a sample-processing step. Output Signals (Out Signals) are sent
from the PAL to external devices to indicate status or completion of particular processing
steps. These signals are classified as Objects. Physical Events (for example, TTL-In1) are also
Objects and may be assigned to named signals. PAL Cycles require that certain signals, such as
Start, Inject, and Injected, be defined. For the PAL Events and signal assignments associated
with the standard PAL LC-Inj and LC-Cut cycles, see Table 51.
Certain types of integration of the PAL System into data handling or control software, such as
ChemStation, Xcalibur, Galaxie or Chromeleon, accomplish synchronization of the
Ready/Start signal directly via software control (RS232/LAN).
To assign a physical Event (for example, SW-Out 1) to an existing signal Object (Injected),
complete the following menu selections:
The Accela Open Autosampler is shipped with all cycle events predefined, as shown in
Table 51. If you need a different physical signal, then you must assign a new Event to the
Object signal.

PAL Loader
This chapter describes how to use the PAL Loader sofware version 2.5.0 (or later).
Contents
• Introduction
• New Features of PAL Loader Software 2.1.x
• Installation of PAL Loader Software
• Multiple Shortcuts Assignment
• PAL Loader Software Operation
• Troubleshooting
• Limitations
Introduction
The purpose of the PAL Loader software is to create a backup file for the complete Accela
Open Autosampler firmware. The core software (firmware) and all PAL Firmware Objects,
including all settings (Items), local methods, and jobs, are saved as one file.
The PAL Loader software has a second function of loading the firmware or a complete backup
file to the Accela Open Autosampler. The PAL Loader application has always been part of the
Accela Open Autosampler.
The following PAL Loader software versions are in use:
• PAL Loader version 1.0.1
• PAL Loader version 1.1.1
A new PAL Loader software, version 2.1.0 or later, has been developed for the Accela Open
Autosampler.
The Accela Open Autosampler requires PAL Firmware 4.1.x or later, which calls for the new
PAL Loader software.

PAL Loader
New Features of PAL Loader Software 2.1.x
The new PAL Loader software version 2.1.0 (or later) is backwards compatible. The software
can be used for all PAL Firmware levels.
The name of the *.exe file has been changed intentionally to avoid conflicts when old and new
versions are installed on the same computer:
PAL Loader version 1.1.1: PALLOAD.exe
PAL Firmware level up to and including 3.x.x.
PAL Loader version 2.1.x: Setup PALloader.exe
PAL Firmware level as of 4.1.x or later
but backwards compatible with lower levels.
New Features of PAL Loader Software 2.1.x
The following features, new since version 1.1.1, are available in the new PAL Loader software:
• The installation software is executable directly from a CD-ROM or any transportable
storage device, such as a memory stick.
• The software installation procedure is different from that of Loader version 1.1.1. If they
do not already exist, directories are created in the Microsoft™ User Profile.
• The read/write speed for a file is significantly higher. The initial COM Port settings, such
as the baud rate, are identical to previous versions. The baud rate is adjusted dynamically
during program startup and is displayed on the status line, in the lower right corner of the
application window.
• You can create multiple shortcuts and for each one assign a dedicated IP or COM address.
This setup facilitates the handling of a number of PAL Systems from a single computer.
Installation of PAL Loader Software
This section contains information about installing the PAL Loader software.
Requirements
PAL Loader software version 2.1.x requires Windows 2000, XP, or Vista™. It does not support
lower Windows versions, such as Windows 95, 98, or NT. If installation is necessary in this
environment, use PAL Loader version 1.1.1.

Installation of PAL Loader Software
Software communication from a PC to the PAL System can be done one of two ways:
(Serial control, requiring a serial cable provided with the PAL System, crossed wiring)
• P/N 00950-01-00332 (cable length 3 m, standard cable)
–or–
• PN: 00950-01-00333 (cable length 6 m, optional cable length)
PAL Loader Software Version 2.1.x Installation
The software is provided with every PAL-xt System, with an enclosed CD-ROM.
The PAL Loader .exe file is embedded in a wizard software package. Starting the wizard will
execute the installation software. If no changes are made to the proposed installation path, the
Loader version 2.1.x uses the following default installation path to install the software:
drive:\Program Files\PAL Loader
Note You can start the wizard for the installation software by double-clicking the icon of
the file Setup PALloader.exe.
You can use the second file, PALloader.msi, for the installation as well. Double-click the icon
of the file, right-click, and choose Install from the shortcut menu. This path for installation
requires an up-to-date Windows Installer. If the current version is not installed, a
corresponding error message appears.
Figure 120. Installation path for the PAL Loader software
The two subfolders Backup and Update are automatically created at installation in this
directory:
drive:\Users\Public\Public Documents\PAL\Loader
The directory allows writing temporary files, with no write protection and, in a network
environment, the User Profile is always provided to the user at logon.

Figure 122. Installation path for PAL Loader INI file
Note that the folder ProgrammData can be hidden if a standard installation of the Windows
Operating system is executed.
Multiple Shortcuts Assignment
The PAL Loader version 2.1.x or later provides for the handling of multiple shortcuts on the
desktop; each one can be assigned to a specific TCP/IP address or COM port. A mix of the
two communication protocols is possible as well.
This setup facilitates the handling of a number of PAL Systems from a single computer.
You can create a shortcut of the PALloader.exe file to the desktop. After you create the
shortcut, right-click the shortcut icon and choose Properties from the shortcut menu. See

not confuse this with the COM port setting, which is a baud rate of 9600. The
application optimizes the speed, depending on work load and processor capabilities.
The dynamic increase in the baud rate can reach as high as 115 200. The last used
baud rate writes back to the PAL Loader INI file. Opening this window from the PAL
Loader application displays this last used rate.

Updating the PAL Firmware
Note Do not move any part of the Accela Open Autosampler, such as the x axis, and if
possible do not use other computer functions during the backup and update process. This
will delay the process and might freeze the application.
Use the following procedure to upgrade the PAL Firmware to another level. Keep in mind
that the existing firmware data, such as parameter settings or methods, is overwritten or lost.
This is especially important for users who work directly from their local terminal and create
methods and jobs within the PAL System. In such cases, ensure that the methods are saved
before starting an update procedure.

Note Best practice dictates creating a backup file as described above before performing an
update of the PAL Firmware. This backup file is for backup purposes only. If an important
point is overlooked, recovery is possible by reloading the backup file onto the Accela Open
Autosampler.
 To create an update file
1. Shut off power to the Accela Open Autosampler.
2. Connect the cable corresponding to the communication mode:
• Serial Cable (RS232) between PAL SER1 and PC Serial port (COM)
PN: 00950-01-00332 (standard cable provided with PAL System) or
PN: 00950-01-00333 (optional, cable length 6 m)
3. Double-click the PAL Loader icon. The PAL Loader startup window appears. The
previously used communication mode is displayed in the status box.

Troubleshooting
If you cannot establish serial communication with the PAL Loader software version 2.1.x,
check the following points:
• Is the COM port on the PC available and correctly addressed?
Are default settings verified?
• Is the PAL Loader software COM port setting correct?
If no RS232 (serial) port is available on the computer, use a USB/Serial converter. Use the
type recommended by CTC Analytics: PNo.: USB-Ser2.
The PAL RS232 cable has a crossed wiring connection.
PN: 00950-01-00332 (3 m length, standard cable) or
PN: 00950-01-00333 (6 m length, optional cable)
How to Force Loader Mode Manually
If basic conditions are met but you still cannot establish communication from the PC to the
Accela Open Autosampler, you must force the PAL System into so-called Loader mode.
This action might be necessary if the PAL Firmware has been partially corrupted.
 To force the Loader Mode manually
1. Turn off the power from the PAL System.
2. Turn on the power again.
3. Turn off the power from the PAL System within a time window of approximately 3 to
5 seconds again (turn it off before the startup logo is displayed on the screen).
4. Turn on the power again.
Successful activation of the Loader Mode is indicated by the blinking red LED at the back of
the PAL x axis.
There are two blinking patterns for the LAN and COM (serial) modes for the Control–xt
board only. The LAN mode exhibits a fast, double-blinking signal, whereas the COM (serial)
mode shows a pattern with one blinking signal at a constant time interval. See a visual
representation of the patterns in Figure 139.

Location of LED:
• For PAL Systems, APR CPU or APR Control boards:
LED is beside the DC connector.
• For the PAL-xt System, APR Control-xt board:
LED is between the buzzer and wash station.
Reset PAL to Serial Communication
If the PAL-xt communication protocol is set to the LAN type, it is possible that the link
between the PAL-xt software and the PAL-xt System can no longer be established. One cause
for such a failure is a corrupt PAL Firmware.
Under these circumstances, you must be able to execute an “emergency” command. This
function is set in the PAL Loader software Setup dialog box using the Reset PAL to Serial
Comm button.
How to Reset the PAL to Serial Communication
 To reset the PAL to serial communication
1. Start the PAL Loader application (version 2.1.x or later) by double-clicking the
corresponding icon.
2. Click Setup and change the Communication Type from the TCP/IP to the Serial
Communication option.

Troubleshooting
Erratic Behavior of Software or Flash Memory
In some rare cases the red LED might continue to blink after a PAL Firmware update. You
cannot start the PAL System from the PAL Loader Start PAL button or by powering it off/on.
If such a case occurs, take the following steps:
1. Power down and wait at least 30 seconds before the unit is powered up again. If the PAL
System is not restored, go to the next step.
2. Reload a complete PAL Firmware backup file. A complete backup file means core
software including all PAL Firmware Objects data, content of RAM, and flash memory.
If this action is still unsuccessful, go to the next step.
3. Power down the unit again and remove the board (APR CPU, APR Control, or APR
Control -xt). Before you handle an individual board, be careful of static charge.
4. Connect the DC cable, the spiral cable for the terminal, and either the Serial or Ethernet
cable to the board on-the-fly.
5. Start the software UPDATE process again.
6. If none of these actions is successful, change the board.
Any severe error requiring changing the board typically means that the Loader section of
the flash memory can no longer be addressed, which results in communication failure.
Note A PCB, APR CPU, APR Control, or APR Control-xt , which has not been
connected to current for a period of six months or longer, can result in a low battery
level. Because a low battery will no longer support the RAM memory, data loss is
likely.
7. Charge the battery overnight (36 V), and reload a complete PAL Firmware backup file
(core software and PAL Firmware Objects).
Failure to Complete BACKUP or UPDATE Process
Avoid touching the PAL System during the read or write processes (BACKUP or UPDATE).
Do not move, for example, the y-, z-axis assembly during a process. This will delay its
completion and could result in an error message and stopping the process completely.
Furthermore, the window can freeze (shown in a frozen progress bar). This might also happen
if the computer processor is very busy with other tasks at the same time. Try to avoid using
any other computer function during the process.

intended for frequent Accela Open Autosampler users or new users who are experienced at
configuring and using automated systems to run existing analytical methods. Before using the
PAL Object Manager, make sure you have properly installed and set up the Accela Open
Autosampler using the instructions in “Installing the Accela Open Autosampler” on page 11.
Contents
• Installing PAL Object Manager
• Getting Started with PAL Object Manager
IMPORTANT Before using the PAL Object Manager software to make changes to your
system, back up the current system definition using the PAL Loader software. If problems
occur while using the PAL Object Manager software, repair the system using PAL Loader
to restore the back up configuration file. See “PAL Loader” on page 211.
Because this software can change your system to the point that the autosampler and
Thermo PAL does not function properly, make changes to objects only if you are an
advanced user and understand how the changes you make can impair system functioning.
Thermo Fisher has defined the hardware and software configuration for your autosampler.
Changes to this configuration can impact system functioning.
When you add a new hardware module to the Accela Open Autosampler, use the PAL Object
Manager software to load new PAL firmware objects onto the system to support those
modules. The Object Manager mode also helps create and maintain object lists from an
existing Accela Open Autosampler.
After adding an object to the Accela Open Autosampler, choose Restart Pal from the File
menu to start the system so other software applications can use the object.
The latest PAL Object Manager software is backwards compatible. You can use the software
with all PAL firmware levels.

Connected on COMN
where N is the number of the COM port.
Troubleshooting the Serial Communication Mode
PAL Object Manager software version 2.1.0. can address only COM port numbers 1 to 4.
The ports must be consecutive. If you connect to one port and do not establish serial
communications, connect to another port. Accela Open Autosampler
This limitation has been eliminated with PAL Object Manager software version 2.2.x.
If you cannot establish serial communication with the PAL Object Manager software, check
the following questions:
• Has the original RS232 cable been used, as provided with Accela Open Autosampler?
(The PAL RS232 cable has a crossed wiring connection.)
P/N 00950-01-00332 (3 m length) or P/N 00950-01-00333 (6 m length).
• Is the COM port on the PC available and correctly addressed?
• Are default settings verified?
• Is the COM port setting in the PAL Object Manager software correct?
If not, the following message is displayed:
Figure 146. Wrong COM Port selected
These types of problems are seen mostly when a USB/Serial port is used to overcome the
lack of a serial interface, as in today's laptop computers.
Note These two limitations surrounding the COM port setting are valid for the
previous Object Manager software, Version 2.1.0. With the release of the new Version
2.2.x these problems are eliminated. The software scans for the available COM ports,
the error message as shown in Figure 146 is no longer displayed.
If no RS232 (serial) port is available on the computer, use a USB/Serial converter.

Installing and Using the PAL Object Manager Software
Getting Started with PAL Object Manager
Using the Object Manager Application
The main purpose of the PAL Object Manager software is to load PAL firmware object lists
on a system that has added a hardware module. To add an object list, follow this procedure,
which describes adding a syringe object to an existing Accela Open Autosampler.
You can only add certain objects to your system. Be sure you know the impact of an object
before adding it to the system.
Ensure that the Accela Open Autosampler is set up properly, the PAL Object Manager
software is installed, and the communication is established as shown in “Setting Up the
Communication Mode” on page 236.
 To add an object list to an existing Accela Open Autosampler
1. In the Object List folder pane, click the Syringes folder.
2. Double-click the subfolder containing syringe firmware to open up the list of various
available LC syringes.
3. In the Object List, select a specific syringe to highlight it.
4. Hold the cursor on the object list item to reveal information about the object.
This information provides the title and an explanation of the selected object.
The Loaded Objects area lists the objects that are loaded with one action. In this example
it is a single object, but with other examples, such as a stack cooler, the situation is more
complex (see Figure 147). Four tray types, a tray holder (CStack1) and six trays (01-06)
are sent to the Accela Open Autosampler in one package.
Figure 147. Object list stack cooler 1 example
Thermo Scientific
Accela Open Autosampler Hardware Manual

C
Installing and Using the PAL Object Manager Software
Getting Started with PAL Object Manager
Review the information to make sure that the correct object list has been selected and to
understand what is included in this list. For example, you need to know whether all
necessary tray types for the application are included or if you must specifically select
another type and send it to the Accela Open Autosampler as a second task.
5. Click Send to Accela Open Autosampler to read the Accela Open Autosampler
configuration and send the selected objects to the Accela Open Autosampler.
The configuration file is temporarily stored in the computer memory.
After the file has been sent successfully to the Accela Open Autosampler, the message “xx
objects received” is displayed in the status bar, providing feedback from the Accela Open
Autosamplerto the Object Manager application.
In the example using the LC syringe, 25 μL, the Object Manager software might send
two objects in a single file. In this case, the first object contains the geometric definition
of the syringe itself and the second object specifies which plunger motor driver is assigned
to this particular syringe.
The same concept is used to send the desired objects to the Accela Open Autosampler for
all other object lists.
The Object Manager always lists the object being sent in the last line of the PAL firmware
class, visible from the local terminal. The Object Manager software can quickly check
whether the PAL firmware has received the new object.
In some cases—seen in particular in the PAL but not in the PAL-xt System—you might
receive an error message: Memory full. To resolve this problem, you must delete as many
objects as possible from the Accela Open Autosampler that you are not using. You can
link a syringe to a method and a job. First delete the job, then the method, and finally the
syringe object. See “To delete objects” on page 240 for information about deleting
objects.
Confirm your understanding of the Object List parameters and descriptions to make sure
that the correct, desired objects are sent to the PAL firmware. In certain cases where
complexity is greater—for example, multi-position valve drives—the guideline provides
the correct order of steps in the process to provide reliable functioning of the Accela Open
Autosampler.
 To delete objects
1. Use the Accela Open Autosampler handheld device to delete objects.
In the handheld device, objects are displayed as a tree. Identify the object and delete it
according to instructions in “Operating the Accela Open Autosampler” on page 65.
To delete multi-object items, delete the lowest items first and then remove higher objects
until you delete the top-level object.
