Figure 1. COMPULAB 3 Modular Dispensing System
The COMPULAB 3 Dispensing System is a microprocessor-controlled, programmable peristaltic pump system designed
to meet liquid-handling needs. The system can be programmed to operate as a dispenser, diluter/dispenser, and an allpurpose pump. The operator designs programs that contain operational parameters. The programs can be run manually
with the controller, a dispensing wand, or by using the optional footswitch, semiautomatically in cycle, or automatically by
specifying the exact number of cycles to be completed.
The control console can control each pump independently, or pumps can be linked and controlled simultaneously.
Operation can be varied to suit specific applications by dispensing cumulative volume, flow in mL/min, and/or by cycle
count. The dispenser can communicate with a variety of balances in order to dispense liquid by weight. A built-in RS-232
interface allows the dispenser to be controlled by a personal computer.
SCOPE OF THE MANUAL
This manual contains instructions for installing, setting up, programming, operating, and maintaining the dispensing
system. It is intended for use by technicians and operators as well as maintenance personnel. TROUBLESHOOTING
contains a list of possible problems, their probable causes, and actions to take to remedy each problem.
Instructions for replacing user-serviceable parts and a list of parts that can be ordered are included. ACCESSORIES
lists all available accessories for the COMPULAB 3. SPECIFICATIONS lists pertinent characteristics of the
COMPULAB 3. APPENDIX A — BALANCE CONNECTION provides pinout and signal information for connecting a
balance to the dispenser. APPENDIX B — PC CONNECTION AND SOFTWARE INSTALLATION provides details to

INSTALLATION
SITE REQUIREMENTS
The COMPULAB 3 Dispensing System is designed to operate in most workplace conditions. Ensure that the work area
temperature range is 0°C to 40°C (32° to 104°F) and that the relative humidity remains between 10% and 90%. Locate
the dispensing system so that it is not exposed to running water and is protected from dangerous chemicals and
excessive or conductive dust.
POWER REQUIREMENTS
The COMPULAB 3 Dispensing System requires 115 (90–130) VAC or 230 (180–260) VAC, 50/60 Hz incoming power.
Each pump drive draws 1.7 A at 115 V or 0.8 A at 230 V.
INTERCONNECTION
Each pump drive is connected to the control console with a 3-1/2 ft (1.1 m) RJ-12 cable (catalog number 77095-02).
Longer cables are available as an option, but are not recommended for use in areas where interference may be high.
Use as short a cable as is practical. Use only cables supplied by Barnant Company.
Refer to Figure 4, and connect the components of the dispensing system. Ensure that the plugs snap firmly into the
connectors on the back of the control console and on the back of each pump drive.
Figure 4. Interconnecting Components
POWER CONNECTION
Each pump drive requires AC power to operate. The power for the control console is supplied by one of the pump drives.
WARNING: The dispensing system must be plugged into a grounded power source only. An ungrounded power
source presents a serious shock hazard.
CAUTION: Ensure that the 115/230 voltage switch on the back of each pump drive is set to the appropriate
voltage before connecting the pumps to the source voltage. Selecting the incorrect voltage can
cause damage to the dispenser.
3
If the voltage selection switch is set to the incorrect voltage, refer
to Figure 5 and set the switch to match the voltage of your AC
source. Slide the switch so the correct voltage is displayed.
115 V
Ensure that the AC outlet is grounded and meets all local and
national codes. The use of ground-fault interrupted AC power is
recommended because of liquid handling. Use the supplied power
cord for each pump in the system. Refer to Figure 4, and attach
the female plug to the connector on the back of the pump drive.
Plug the male connector into a properly grounded AC outlet.
BALANCE CONNECTION
In order to operate the dispense program with a balance, a
compatible balance must be connected to the control console.
The COMPULAB 3 provides communication to the balance
through a nine-pin male RS-232 DTE port on the back of the
control console. Refer to APPENDIX A — BALANCE
CONNECTION for a list of compatible balances and a description
of the RS-232 connections.

TUBING SELECTION
Flow rate is determined by the size of the tubing in the pump head. For best results, select a tubing size with a mid-range
at the desired flow rate to be pumped. Table 3 provides an average of flow rates using silicone tubing measured with
water at standard pressure at 20°C (68°F) for each pump type. No lift or discharge pressure is represented. Higher flow
can be achieved by using PHARMED® or NORPRENE® tubings.

1. Ensure that you have selected the correct tubing size for the application.
WARNING: Turn off the system before removing or installing tubing. Disconnect the pump drive from the AC
source to prevent accidental starting of the drive mechanism. Fingers or loose clothing can be
caught in the pump mechanism, causing serious injury.
2. Make sure that the power switch is turned off and the pump drive is disconnected from the power source.
3. For the RD-1: Loosen the two knurled nuts holding the clear plastic cover, and slide the cover off the pump head.
For the RD-2: Remove and retain the four knurled nuts holding the clear plastic cover, and remove the cover from the
pump head. Remove and retain the two thumbscrews that secure the tubing clamp, and remove the clamp.
4. FOR TUBING LINKS:
NOTES: The tubing links for RD-1 and RD-2 come with washers that need to be placed outside of the pump. The
washers ensure a snug fit in the pump.
Tubing links are not available for number 18 (5/16 in. ID) tubing.
a. Refer to the instruction sheet that came with the tubing link. Refer to Figure 8, and align the tubing link to its path
through the pump head, ensuring that the mounting washers of the link are as close as possible to the outside of
the pump head.
NOTE: The male connectors on the tubing links are removable. Rotate each a half turn counterclockwise to remove
the connector, and a half turn clockwise to reinstall the connector.
b. Attach input and output ends of the transfer tubing to the connectors of the tubing link.

c. Manually rotate the roller assembly while guiding the tubing between the rollers and the pump head wall. Ensure
that the tubing is in the center of the channel.
5. FOR TUBING:
a. Insert tubing between the rollers and the pump head housing in the center of the channel, midway between the
clear plastic pump head cover and the pump head housing bottom. This ensures that the rollers depress the
entire width of the tubing as they turn.
b. Feed the tubing in, and manually rotate the roller assembly. Guide the tubing between the rollers and the pump
head wall.
c. Pull gently on the input and output sides of the tubing to create a gap between the tubing and the curved pump
head housing wall.
There should be a small but visible gap between the tubing and the pump head housing for about 1/3 to 1/2 of the
contact surface at any time.
NOTE: The clear plastic pump head cover is reversible on the RD-1 models. It has different size tubing retainers on
each face. If the tubing is smaller than 3/16 in. ID, place the cover so that the larger tubing retainers hold the
tubing. If the tubing is 3/16 in. ID or larger, reverse the cover.
6
6. For the RD-1: Slide the clear plastic cover over the pump head and tighten the knurled nuts to secure the tubing.
7. For the RD-2: Reinstall the tubing clamp and secure with the two thumbscrews so that the clamp holds the tubing in
place but does not pinch the tubing. Replace the clear plastic cover and the four knurled nuts.
Tubing life can be extended by periodically shutting down the pump and moving the tubing so that a different segment is
in the pump head, thereby avoiding excessive tubing wear at any specific point.
When using tubing links, the tubing in the link may bunch up at the output end over an extended period of use. Replace
the link, or gently pull on the output side of the tubing link to eliminate the bunch. Pulling the tubing too much will change
the flow rate and adversely affect accuracy.
POWER ON
After the control console and all the pump drives are properly connected and the drives are plugged into an AC source,
the system may be powered up. Refer to Figure 2, and place the POWER switch on one of the pump drives in the On (I)
position. The pump number appears on the LED display. The welcome screen appears on the control console.
Place the POWER switch on the remaining pump drives in the On (I) position.
If the system does not power up, place the POWER switch in the Off (O) position. Check that all interconnection wiring is
secure. Make sure that the voltage selection switch on the back of the pump drive(s) are set to the correct voltage.
Ensure that the pump drive(s) are plugged into a live, grounded AC source.
If the system powers up but the pump number 0 (zero) is displayed, the pump drive is not properly connected to the
control console. Place the POWER switch in the Off (O) position, check all the interconnections, and place the POWER
switch in the On (I) position.

GENERAL
Programs may be designed and saved, or may be run immediately without saving. After the program is run, the user can
modify the program, try it again, and when satisfied, save it. A designed program that is not saved will be lost if power to
the dispenser is removed. After the program is saved, it may be run, modified, and saved under the same or another
number.
Settings for optional parameters such as acceleration ramping, deceleration ramping, and no-drip are usually
determined through trial and error. Acceleration and deceleration are programmed separately. Acceleration is the
amount of time in seconds it will take the pump to reach the programmed speed. A setting of 0.0 (zero) instructs the
pump to reach the programmed speed as quickly as possible. Deceleration is the amount of time in seconds it will take
the pump to slow to zero from the programmed speed. A setting of 0.0 (zero) instructs the pump to stop as quickly as
possible. Use acceleration/deceleration to minimize splash of dangerous materials or to improve accuracy when
dispensing viscous materials.
A no-drip value instructs the pump to reverse direction before stopping, preventing fluid in the tubing from dripping after
the pump has stopped. The best no-drip setting is dependent on tube size, rate, physical setup, and viscosity of the fluid
being pumped. No-drip can be set from 0 (zero) to 10, where 10 equals one pump revolution.

CREATE OR EDIT A DILUTE PROGRAM
For use as a diluter, the pump is first primed with the diluent. Then, a dilute cycle consists of two separate actions,
sample and delivery. For the sample action, the outlet end of the tubing is placed in the container holding the sample.
The pump runs opposite the programmed direction to draw the sample volume into the tube. For the delivery action, the
outlet end of the tubing is moved to the receiving container, and after the hold time, the delivery volume is pumped out of
the pump. The sample volume plus the diluent volume equals the delivery volume.
To create a new dilute program, ensure that the console displays the PROGRAM MENU. If any other menu appears,

OPERATING PROCEDURES
Before performing any of the procedures in this section, be sure that the correct size tubing is properly loaded. Refer to
SETUP to mount the pump heads and install the tubing.
You may run the same program to four pumps, or different programs for each pump.
A program designed for a pump drive with two heads will run on a pump drive with one head mounted, but the flow rate
will be only half of the expected rate. A program designed for a pump drive with one head will run on a pump drive with
two heads mounted, but the flow rate will be double the expected rate.
Linking Pumps
For pumping or dispensing operations, two or more pump drives may be linked so that they operate and are controlled
simultaneously. All linked drives start with a single key press or by one external signal. All linked drives must be set up to
run the same type of program.
NOTE: Dilute programs cannot be linked.
13
For pump programs, all linked pump drives begin when the RUN arrow key is pressed or the external start/stop contact
closure is closed for any linked pump. The pumps continue running until the CANCEL/STOP or STOP ALL key is
pressed or until the external start/stop contact closure is opened for any linked pump. All pumps pause simultaneously. All
pumps start over or resume simultaneously when the appropriate arrow key is pressed. An external signal resumes all
pumps.
For dispense programs, all linked pump drives begin when the RUN arrow key is pressed or the external start/stop
contact is momentarily closed for any linked pump. The pumps continue running until the CANCEL/STOP or STOP ALL
key is pressed or until the external start/stop contact signal is momentarily closed. All pumps pause simultaneously. All
pumps start over or resume simultaneously when the appropriate arrow key is pressed. Momentarily closing the external
start/stop contact also resumes all pumps. If not interrupted, each pump continues to run until the programmed volume is
dispensed. For programs with multiple cycles, each pump must complete a cycle, then a new cycle simultaneously starts
all linked pump drives.
Use the following procedure to link pump drives. Ensure that the PROGRAM MENU is displayed. If it is not, press BACK

Running Programs
NOTE: Before continuing, be sure that the pump heads are mounted and that the correct size tubing is properly loaded
and routed to the correct locations.
If the pump number shown in the upper right corner of the display is not the pump that is going to run the program, you
will have to reload the program to run it on that pump. The program stays in memory, assigned to the active pump when
loaded. Change the pump number by pressing PUMP# on the control keypad. When the correct pump number is
displayed, refer to LOADING A PROGRAM, press the arrow key under PROGRAM, and load the desired program.
NOTE: Ensure that the number of pump heads mounted on the pump drive is the same as the number of heads the
program is designed to run. If the number of heads do not agree, the program will not operate properly.

4. Press ENTER to continue.
Performing a Calibration
You must prime the pump to purge the air from the tubing before calibrating, dispensing, or diluting. Air in the tubing will
also cause an inaccurate volume display while a pump program is run.
NOTES: If the pump has never been calibrated, the default range for the selected tubing size is displayed. If the pump
has been calibrated, the valid range for the tubing size is calculated based on the results of the calibration.
The dispensing system stores the calibration for each tubing size in each pump number (1–4).
Before continuing, ensure that the tubing is properly loaded and the pump is primed.

MAINTENANCE
SAFETY
The procedures in this section must be performed with power removed from the dispensing system. Attempting to
perform the procedure without power removed can result in serious injury or death. If you are unsure of the status of
electrical power, DO NOT perform the procedure. The capacitors in the power supply section of the pump drive maintain
high voltage for up to ten minutes after power is removed. Allow sufficient time for the capacitors to discharge before
removing the cover for servicing.
Refer to USER-REPLACEABLE PARTS for the part numbers of all the user-replacement parts.
CLEANING
WARNING: Disconnect the dispenser from the AC source before cleaning. A shock hazard exists when using
water on powered equipment.
Keep the dispenser enclosures clean by using a mild detergent and water solution. Never immerse the unit in water or
use excessive fluid when cleaning the dispenser. Dry the dispenser before restoring power.
FUSE REPLACEMENT
If you suspect that the fuse has blown, use the following
procedure to remove, check, and replace the fuse.
CAUTION: Always replace the fuse with the same
type and rating as the blown fuse. Using a
fuse of a different type or with a different
rating can cause damage to the pump
drive.
1. Unplug the power cord from the AC source.
2. Ensure that the power switch is in the Off (O) position,
and remove the power cord from the back of the pump
drive.
3. Refer to Figure 16, and use a small screwdriver to pull
out the fuse tray.
Figure 16. Fuse Replacement
4. Slide the defective fuse out of the fuseholder.
19
5. Remove the spare fuse and slide it into the fuseholder in place of the defective fuse.
NOTE: Replace the spare fuse as soon as is practical.
6. Push the fuse tray in until it snaps into place.
7. Make sure that the voltage selection switch matches the AC power source.
8. Reconnect the power cord to the connector on the back of the pump drive.
9. Plug the power cord into the AC source.
10. Place the power switch in the On (I) position.
NOTE: If the fuse blows repeatedly, there is a problem with the pump drive. Contact your distributor or Barnant
Company Technical Support for help.
BELT REPLACEMENT
If the dispenser powers up properly and appears to be
operating correctly at the control console, but the pump does
not turn, it is possible that the belt has broken. Use the
following procedure to inspect and, if necessary, replace the
belt.

3. Refer to Figure 17 and loosen, but do not remove, the two nuts that secure the motor to the top of the motor
mounting brackets.
WARNING: Be careful when working near the fan end of the motor. The fan blades are sharp.
NOTE: It may be necessary to loosen the lower two nuts that secure the motor to the mounting brackets in order to
perform the following step.
4. Pivot the motor toward the pump, and remove the belt from around the motor pulley.
5. Remove the belt from around the pump pulley.
6. Install the replacement belt around the pump pulley and around the motor pulley.
7. Pivot the motor so the belt is taut, and secure the motor in position by tightening the nuts loosened in step 3 just
enough to hold the motor.
8. Test belt tension by pressing on the belt midway between the pulley. The belt should flex approximately 1/8 in
(3 mm).
9. If belt tension is correct, tighten the nuts securely. If tension is not correct, loosen the nuts and repeat step 7 and
step 8.
10. Reinstall cover and secure with eight screws.

BRUSH REPLACEMENT
Exact motor brush and commutator life will depend on duty cycle and motor operating speed. Inspect the brushes every
six months or after 2000 hours of operation, whichever occurs first. Replace brushes if they are less than 0.3 in (7.6 mm)
long. Inspect the commutator when the brushes are replaced, and clean if necessary.
DANGER: Never remove the cover from the pump drive when power is present. AC and DC power in the pump
drive can cause serious injury or death. Ensure that the pump drive is disconnected from the
power source before removing the cover for maintenance. Allow ten minutes for the capacitors in
the power supply to discharge before proceeding.
1. Refer to BELT REPLACEMENT, remove the cover, and remove the belt from the pulley on the drive motor.
2. Pivot the motor away from the pump to gain access to the brush on the pump side of the motor.
3. Refer to Figure 18, and remove the brush caps.

APPENDIX A — BALANCE CONNECTION
The following balances have been confirmed as compatible with
the COMPULAB 3. Other balances may work with the dispenser,
but have not been tested by Barnant Company.
A&D Model GF2000 (part number 11133-08)
OHAUS® AdventurerTM 3100g × .01g (part number 01010-50)
OHAUS® VOYAGER® Model V1D120 (part number 11014-10)
METTLER TOLEDO Model PG5002-S DeltaRange®
SARTORIUS® Masterpro Model LP4200 (part number 11212-20)
RS-232 CONNECTOR ON CONTROL CONSOLE

The COMPULAB 3 provides communication to the balance
through a nine-pin male RS-232 DTE port on the back of the
control console. The COMPULAB 3 communicates at 9600 baud,
7 databits, 2 stop bits, odd parity. The balance must be set up to
communicate at that protocol and must be set up to measure in
grams. Table 6 shows pin connections and signals necessary for
the dispenser to communicate with the compatible balances.

APPENDIX B — PC CONNECTION AND SOFTWARE INSTALLATION
The COMPULAB 3 provides communication to a personal
computer through a nine-pin female RS-232 DCE port on the
back of the control console. The COMPULAB 3 communicates
with software provided with the system to provide an alternative
user interface to access all the capabilities of the system. Figure
20 shows pin connections and signals necessary for the
dispenser to communicate with the computer.
A complete description of the serial communication protocol can
be found on the enclosed CD-ROM (kit part number 77310-10).
The COMPULAB 3 Control Software can be used to program or
operate the dispensing system from a PC using the WINDOWS®
95/98 or WINDOWS NT® operating system.
Use the following procedure to install the COMPULAB 3 Control
Software:
1. Insert the COMPULAB 3 Control Software CD in the CDROM drive.
2. Run the installation program, setup.exe in the root directory.
3. Follow the instructions on the screen during the setup
