2-1
Installation 2
Locator Plate Installation
The locator plate serves two functions:
• Positions the racks and accessories that fit onto
the bed of the liquid handler.
• Contains liquid spills, such as those caused by
overflowing vessels.
Locator Plate Installation
The locator plate and its four mounting screws are
shipped in a separate box with the liquid handler’s
accessories. To install the locator plate onto the
instrument bed:
1 Make sure the locator plate’s rinsing station
base is at the rear of the instrument. The locator
plate will only install in this orientation.
2 Align the four corner holes of the locator plate
with the four holes on the instrument bed and
lower the plate onto the bed.
3 Using a Phillips screwdriver, secure the locator
plate using the four mounting screws.
2-2
Installation 2
Armlock Removal
The armlock on the liquid handler secures the Y-arm
during shipment. You must remove the armlock
prior to installing the Z-arm and operating the
instrument. If the armlock is not removed, the
liquid handler cannot move in the X-direction. This
results in an error state during operation.
If you need to move the liquid handler, always
reinstall the armlock. This safeguards against
mechanical damage.
To remove the armlock:
1 Remove the cardboard label in front of the
armlock.
Armlock Removal
2 Using the 9/64" ball driver, loosen the
tensioning screw that immobilizes the Y-arm.
3 Using the 9/64" ball driver, remove the two
remaining screws that hold the armlock in
place.
4 Remove the armlock and store it and the ball
driver for future use.
2-3
Installation 2
Z-Arm Installation
Follow these steps to install the Z-arm:
1 Using a Phillips screwdriver, loosen the
mounting screw on the Z-arm mounting
Z-Arm Installation
bracket located on the Y-arm. Turn
counterclockwise to loosen.
2-4
2 Partially pull out the bracket. Do not remove
completely.
3 Place the Z-arm into the mounting bracket. You
will need to insert one side of the Z-arm into
place at a time.
4 Tighten the screw on the mounting bracket
until the Z-arm is secure.
You’ll adjust the Z-arm to its proper height
after rack and rinse station installation. This
adjustment is described on page 2-14.
Installation 2
Installing the Z-Arm Cable Support Rod
1 Using the two Phillips screws, attach the cable
support rod bracket in the holes located in the
rear of the X-arm extrusion.
Z-Arm Installation
2 Extend the arm to the extreme X- and Y-direction
to ensure that the cable will have enough slack.
Plug the Z-arm control cable into the back topside
of the control cabinet. The control cable should be
tucked into the groove located in the top of the
X-arm extrusion. The retaining clip that is already
on the control cable should be snapped onto the
top of the cable support rod. Refer to diagram
below.
2-5
Installation 2
Probe Installation
There are different probes available for use on the
Quad-Z 215 Liquid Handler. Depending upon your
application, you have purchased the appropriate
probes and probe guide inserts. When installing the
Probe Installation
probes or custom sized probe guide inserts (1.3 or
1.5 mm) refer to the following procedures and
diagrams.
Installing the Probe Guide Inserts
Your Quad-Z is delivered with 1.5 mm probe guide
inserts installed. If you ordered custom sized probe
guide inserts for more precise XY accuracy, refer to
the installation instruction below.
To install the probe guide inserts, turn the insert
clockwise into the probe guide.
Installing the Probes
Insert the probes into the top of the isolation probe
holders and pull them through the holders and the
probe guide inserts until the tip of the probe is in
the probe guides.
2-6
Installation 2
Plumbing Connections
Transfer Tubing Installation
1 Connect one end of each piece of transfer
tubing to the 444 QuadDilutor. Refer to the 444
QuadDilutor User’s Guide for more information.
2 Locate the level sensing cables (LLD cables)
supplied with the Z-arm.
3 Pass the other end of each transfer tubing
through the open end of an LLD cable casing
nearest the right-angle connector. The tubing
should exit the back of the LLD cable casing
approximately 6.5 cm from the end.
4 Connect each tubing to the top of the isolation
probe holder using a 1/4"-28 nut and ferrule
supplied with the tubing. Firmly tighten this
fitting using the supplied headless nut extender
(part number 49041032) since it holds the probe
in place.
Plumbing Connections
2-7
Installation 2
Installing the Level Sensing Cables
To install the level sensing cable:
1 Plug the right-angle connector on one end of the
cable into socket one on the back of the Z-arm.
Plumbing Connections
2-8
2 Snap the cable into the LLD cable guide (refer
to the picture above).
3 Loosen the small hexagonal nut on the probe
holder for probe one. Attach the split-tongue
connector to the nut. Retighten the nut until
snug (approximately one turn after finger
tightening).
4 Repeat for probes 2 through 4.
Installation 2
Rinse Station and Drain Waste Tubing Installation
You’ll clean the probe using the rinse station. To
eliminate carryover of liquids, the rinsing procedure
pumps an excess volume of diluent or probe
washing solution through the probe and out into
the rinse station. The small diameter of the rinse
station inserts allow the outside of the probe to be
washed along with the inside.
The rinse station’s design accommodates three
kinds of rinses:
• Shallow-pocket rinse - Used
for level sensing applications
where the probe is only
immersed in a few
millimeters of the sample.
Plumbing Connections
• Deep-pocket rinse - Used
for non-level sensing
applications. This type of
insert allows for a deeper
insertion of the probe into
the rinse well resulting in a
greater area of the outside
of the probe to be rinsed.
• Flow-through rinse - Used
in applications where a
rigorous wash of the
probe’s exterior is required.
A second source of liquid is pumped to the
rinse station to perform this type of rinse.
It may be necessary to vary the types and
volumes of probe wash solutions to most
efficiently eliminate carryover of particular
compounds. Generally, the smaller the volume
of probe wash solution used, the faster your
automated liquid handling protocol.
2-9
Installation 2
Installing the rinse station
The base of one rinse station is shipped already
secured to the locator plate and is located at the
rear of the locator plate. The locator plate can hold
an optional second rinse station or you can move
the rinse station base to the alternate location.
Before installing the rinse station, make sure the
Plumbing Connections
locator plate has been properly installed with the
previously-installed rinse station base located at the
rear of the instrument bed.
To install the rinse station onto the base, follow
these steps:
1 Align the triangle on the bottom of the rinse
station with the base.
2 With the rinse station’s fittings facing you,
insert the rinse station into the base.
3 Press down and turn the rinse station clockwise.
The rinse station is secure when you feel the
rinse station snap into place. When installed
correctly, the fittings point toward the control
cabinet.
4 If you will be doing shallow- or deep-pocket
rinses, connect waste tubing to the barbed
fitting installed on the rinse station.
If you will be doing flow-through rinses,
remove the plug installed on the rinse station
and replace it with a barbed fitting. Connect
tubing between the barbed fitting and the
external liquid source.

Rinse Site
Configuring the Liquid Handler
The instrument stores the location of a rinse site in
memory. This allows the instrument to move to this
location before homing the syringe and prevents
the spilling of waste liquid or rinse diluent.
You must modify the rinse site coordinates if you
have a Quad-Z 215 Liquid Handler. Refer to the
following table to select the correct X, Y, and Z
coordinates depending on the kind of probe rinse
that will be performed. Coordinates for the rinse
site are provided for the X, Y, and Z axis in
millimeters. The coordinates identify the rinse site
for the left-most probe installed on the Quad-Z 215
Liquid Handler.

Operation 3
Liquid Detector
The Liquid Detector tab allows you to adjust the
default sensitivity for liquid detection.
Note: Gilson control software (such as 735 Sampler
Software) will override these settings.
Configuring the Liquid Handler
Raising the percentage suppresses false liquid
detection while lowering the percentage increases
sensitivity for situations where liquid is harder to
detect. By lowering the probe so it touches the
liquid for one of your samples, you can manually
test the current sensitivity of the liquid detection. In
this manner, you can observe the amount of
change you might expect with each sample.
The factory default setting is 10% for each probe.

Z Height
Configuring the Liquid Handler
Use the Z Heights tab to identify the size of the
installed Z-arm and the height at which the Z-arm
is clamped.
The tower height options are inactive for the Quad-Z
215 Liquid Handler because there is only one tower
height available.
The Z-arm can be clamped at an adjustable height
over the locator plate. You can set this height so that
the liquid handler is able to properly find heights that
you specify. Type the clamp height in millimeters. A
clamp height of 0 mm means the Z-arm is flat on the
locator plate.
3-12
Operation 3
Home Phase
Use the Home Phase tab to display the current Xand Y-phase of the instrument.
Clicking Start causes the liquid handler to perform
the phase procedure. This procedure consists of the
liquid handler homing itself 10 times.
Configuring the Liquid Handler
The liquid handler finds out where home is located
by “feeling” for the back and left walls of the unit.
The liquid handler expects to find these walls in the
same place each time. If it does not, you will get an
error. If this error was caused by an obstruction,
just clear the obstruction and try again. If the
problem does not clear or if a change is made to the
mechanics, you will probably need to repeat this
option to find the true home location.
Once the process completes, the spreadsheet
displays the values generated from each phase
procedure.

Operation 3
Safety Contact
Configuring the Liquid Handler
The instrument has provisions for connecting safety
devices that your application may require, as long
as they present a contact closure or TTL type
interface. The Safety Contact tab allows you to
specify which input contact is connected to the
safety device and what is the active state of that
device. The function of the safety contact is
equivalent to pressing the Stop button on the
instrument’s front panel.
Bearing Life
The Bearing Life tab displays the XYZ travel in
kilometers.

GSIOC Commands
The Gilson Serial Input Output Channel (GSIOC) is an asynchronous serial communications
interface that enhances the power of your Gilson equipment.
The GSIOC incorporates an EIA RS-485 interface and allows up to 32 slave devices to be
controlled from a single master in a multi-drop configuration.
Each slave device is identified by a unique number which must be known to the device
and to the computer. The default ID code of the Quad-Z 215 is 22.
To control the Quad-Z 215 Liquid Handler via the GSIOC interface, you will need the
following:
• a personal computer with Microsoft® Windows® 98 or Windows NT® and any Gilson
control software or 706 Device Driver Software installed
• an unused RS-232 communication port
C
From the controller, you:
• specify the Quad-Z 215 as the device you want to control
• issue commands that set operating parameters, control operation, or request
information from that instrument.
C-1
Appendix C
GSIOC Commands
There are two kinds of commands that you can
send over the GSIOC:
• Buffered commands send instructions to the
liquid handler. These commands are executed
GSIOC Commands
one at a time.
• Immediate commands request status
information from the Quad-Z 215. These
commands are executed immediately,
temporarily interrupting other commands in
progress.
GSIOC Command List
In the command list on the following pages, the
GSIOC command must be entered in the proper
upper or lower case format. If a buffered command
requires additional information, you’ll see italicized
text next to the command. The description of the
command identifies what you need to enter in place
of the italicized parameter. Also note that if a
parameter is optional, it appears within brackets, [ ].
I - Immediate
B - Buffered
Command Type Description
% I Identifies the selected slave device. Returns character
string: “215QADVx.yz”, where x, y, and z represent
software version.
$ I Resets the Quad-Z 215. Returns “$” and resets the
instrument to its power-up state which:
• clears any error state
• relaxes all axes
• opens contact closure inputs
