FilterTec Plus Quick Start:

The FilterTec Plus is shipped in conjunction with a 3-Filter Testing Station. This Station
consists of 3 balances with cables, the Serial3 Balance Interface box, and a stand and clamp
set for holding your 3 filters over the balances. A 6-way Rotary Valve may also be purchased
with this system and its actions implemented in the Programmable R-P Mode.

This system is designed around a set of 3 matching balances, and can be configured in a
couple of ways.

The first uses one head to provide solution through a manifold to 3 filters while monitoring or
controlling the pressure of a single sensor, with each filter ending above its own balance, as
shown below:

A constant pressure can be easily maintained, and the collection rates achieved will be based
upon the dynamics of the filter. If the filters are the same, the Feed Rate will be roughly spit into
thirds.

The second multiple balance configuration utilizes 3 pump heads, 3 sets of tubing, all 3 sensors
and balances, with everything running in parallel.

13

This setup puts the control of the feed rate in the hands of channel 1 with channels 2 and 3
being similar, but not always identical. To minimize differences, use tubing from the same
manufacturer and lot whenever possible.

Also, while only one of the 3 sensors will be used for control, each sensor and balance will
provide independent alarms based on the system’s settings. When in Constant Pressure Mode,
the source sensor’s channel is controlled, and the other channels will be similar but not
identical.

Setup:

1. Plug in and turn on all three balances and the FilterTec Plus.

2. Connect the balances to the scale ports on the FilterTec Plus, labeled S1, S2 and S3.

3. Connect all three SciPres Disposable Pressure Sensors.

4. Connect the SciTemp Disposable Temperature Sensor if using one.

5. Connect the FilterTec to your PC if collecting data, via either the Printer or USB ports.

6. Select the appropriate tubing to use for your tests. If using multiple channels, obtain
enough from the same manufacturer’s lot to do all the plumbing if possible.

7. Cut the tubing to the appropriate lengths required to reach from your solution reservoir
through the pump head and to the pressure sensor and filter.

8. A Fittings kit is included with the FilterTec plus when shipped, and any barbed Luer
connectors required can be found there. Also included are small cable ties that should
be used to reinforce the barbed fittings, in particular where high pressures will be
encountered.

9. Review and set the parameters of the system. Most items have usable and
recommended defaults. In particular, you will need to set the Pump Rate in Constant
Rate Mode and Pump Pressure in Constant Pressure Mode as they default to zero.

10. Use the Prime button to prime the tubing and wet the filters.

11. Press Exec and Run when ready to start the process and begin data collection.

12. Please refer to the FilterTec manual for descriptions of the parameters and modes.

13. Parker strongly recommends testing and calibration of the system with distilled water or
a surrogate solution prior to running your process fluids.

Part A: FilterTec Plus Hardware

1.0 Overview:

The FilterTec Plus is a DEF laboratory-scale filtration system that automates filterability studies
and dead end filtration processes. In DEF, process solution is pumped through a filtration
device, typically a 47mm diameter disk filter or something larger, having a user-selected
porosity. In contrast to older, less efficient DEF procedures, Parker’s new “Pmaintain” Alarm
method automates direct flow filtration (DFF) of dilute protein solutions while providing a 35­50%* increase in filter utilization and filtration yield. (*process solution dependant)

Parker’s new “Pmaintain” Alarm method consists of the following steps: Initially, a user-defined
constant pump rate is implemented in Constant Rate Mode until a user-defined pressure limit is
reached. At this point, the fluid handling system automatically switches to a constant pressure
delivery, i.e. modulating the pump output until a user-defined lower filtration flow limit (collection
rate) is reached and the pump automatically stops.

The FilterTec Plus system provides ease of use and operational safety: Several user
definable alarm conditions can be continuously monitored and displayed.

The user defined alarms include:
 High Pressure Alarm to monitor filter

plug-up conditions, the Pmaintain Alarm is
part of this Alarm menu, will change the
unit from Constant Rate to Constant
Pressure at a user-defined limit.

 Low Pressure Alarm to monitor system

leakage.

 Low Flow Alarm to monitor filter plug-up

conditions. Used along with Pmaintain in
High Pressure Alarm to terminate the
filtration process.

 Hi Temperature to monitor the

temperature of your solution.
All alarms provide an auditory signal; the pump stops when user defined alarm limits are
exceeded. Alternatively, any alarm can be selectively disabled. All pump filtration, as well as
alarm parameters can be printed out at user defined time intervals with a Parker serial printer.
Alternatively, all of the collected data can be sent to a supervisory computer for data archiving
using SciDoc or HyperTerminal.

 Cumulative Volume Alarm to monitor

total volume based on the feed rate.

 Filtrate Weight Alarm to quantitatively

measure the filtrate yield.

 Run Time Alarm that stops the pump

action when a user defined filtration time
has elapsed.

 Hi and Low Analog Alarms allow you to

monitor inputs from other devices to
control your process. (pH, conductivity or
turbidity sensors, etc.)

The Masterflex Easy-Load II peristaltic pump heads can accommodate PharMed and Platinum­cured Silicone pump tubing, including sizes 13, 14, 16, 25, & 17. If equipped with the lager
model, sizes 15, 24 & 35 can be accommodated. Feed rates for all pump tube sizes are factory
calibrated; however, the user can easily recalibrate with a single keystroke from the FilterTec
Plus front panel. The pump head delivers flow rates ranging from 0.03 ml / min. to 2200 ml /
min. for each of the two pump channels depending on motor rpm.

NOTE: The FilterTec Plus usually is configured with a 160-rpm motor. However, if your flow rate
needs require, the FilterTec Plus is available with either a 600-rpm or 8-rpm motor. In Setup:
Pump: Motor: Rpm, select the RPM of your installed motor. By doing so, the FilterTec Plus will
select the appropriate factory installed calibration curves and flow rates.

15

2.0 Front Panel: Data Entry & Display

The front panel consists of a user interface, which includes an alphanumeric display and a
membrane keypad to select operational modes and alarm settings. The display is a two line, 20
characters each, liquid crystal display (LCD). The display is backlit to allow easy viewing over a
wide range of lighting conditions.

The lower line on the LCD is used to signify the function of the “soft keys” marked “A”, “B” and
“C”. The “soft key” current labels are displayed in the lower line of the LCD. If you press these
keys, then the function displayed above it is performed.

The main keypad consists of eight “hard” keys whose function does not change. These keys are
used for basic control and programming of the FilterTec Plus. The basic key definitions are:

Executes the selected operational mode and starts pump. (Run Command)
Interrupts current operational mode and stops pump. (Stop Command)

Sets pump RATE in ml/min, or PRESSURE in psi, depending on Mode being
implemented. Allows “on the fly” changes in Rate or Pressure Modes.

Used for Time statement in Programmable R-P Mode.
Sets motor direction, counter-clockwise or clockwise.

Changes between alternate displays in all modes. (Access to TTL 1-4 in Programmable
R-P Edit Mode.)

Exits current operational mode or menu level, stops pump.
Used for flow rate re-calibration. (Valve Control in Programmable R-P Mode.)

Two LED’s are also on the front panel, just to the left of the main keypad. These indicate the
current pump status. A green light indicates the pump is in motion; the red light indicates that
the pump has stopped.

1.0 Software Overview: Main Menu

The FilterTec Plus main menu consists of five (5) operational modes as shown on the
previous page. Use the “Up” and “Down” keys to scroll through the main menu. Press the
“Select” key to enter a chosen operational mode, i.e. CONSTANT RATE. Pressing the “Select”
key enters the 1
functions in most modes. In the “Edit” submenu, the pump parameters are selected. In the
“Exec” submenu, the parameters chosen under “Edit” are executed. The “Prime” key runs the
pump when the key is held down to ‘prime’ the system and removes the air bubbles when
needed. Press the “Exit” key to return to the main menu. Pressing “Exit” repeatedly will always
return to the top of the menu.

CONSTANT RATE Mode: This operation mode allows implementation of a Constant Rate /
Constant Pressure Filtration, i.e. a user selected rate (filtration feed rate) is maintained during

the initial phase of the filtration. If the “Pmaintain” alarm is enabled, the unit will change from
constant rate to constant pressure control at a user defined pressure level. In the “Edit”
submenu first select the pump tubing you want to use in your application. Based upon your tube
size selection, the FilterTec Plus will access factory installed calibration tables, which relate the
pump output in ml/min. to pump motor speed. Please note: the flow rate calibration data can be
updated by the user utilizing the star () key. This provides simple modification of the factory­installed data for a particular motor/pump head/tubing combination.

st

submenu level, which provides access to the “Exec”, “Edit”, and “Prime”

Several user-programmable Alarms can be selected: Cumulative Volume; Hi Temperature; Run
Time; Lo-Pressure; Hi-Pressure; Filtrate Weight, or Low-Flow.

Each alarm can be: 1. Off (Disabled), 2. Alarm Only (Provide auditory alarm), or 3. Stop Pump
(Provide an auditory alarm and stop), and are triggered when alarm limits are exceeded. The Hi­Pressure alarm has one additional option, 4. Pmaintain, which changes from rate to pressure
control at a user defined limit. The FilterTec Plus simultaneously monitors and displays up to
three line pressures needed for filter train evaluation as provided by the three SciPres
Disposable pressure sensors. The Hi and Low Pressure alarms relate to the pressure sensor
chosen as the “Pressure Source” as defined in the SETUP: Pump, Press Sensor submenu

At user-defined intervals, all filter/pump parameters can be printed out or send to a PC for
archiving. Print parameters are set in the SETUP: Printer. The balance allows quantitative
filtrate collection by weight, use of the Filtrate Weight alarm mentioned above, along with the
display and printout of the Collection Rate.

CONSTANT PRESSURE Mode: This operation mode allows you to implement Constant
Pressure Filtration, i.e. a user selected filter backpressure is maintained by modulating the

pump output. When the filtration device starts to plug up, the FilterTec Plus will maintain the
selected filter backpressure by automatically decreasing the feed rate. The FilterTec Plus
simultaneously monitors and displays up to three line pressures as provided by the 3 SciPres
disposable pressure sensors. The process can be controlled by any one of the 3 line pressures
as selected by the user in the SETUP: Pump, Press Sensor; Source submenu. The filter
backpressure setting, Pump Pressure, is selected in the “Edit” submenu. This setting allows
you to choose a safe backpressure that also is consistent with a desired filtrate flow rate.

NOTE: All Alarm, Print and Balance parameters are the same as discussed in CONSTANT
RATE Mode, except for the replacement of the Hi-Pressure Alarm with a Low-Flow Alarm.

PROGRAMMABLE R-P Mode: This mode allows you to implement variable Feed Rates or
Pressure Rates that change over time in a Stepped (immediate change) or Scanned (ramped)

22

manner. This is accomplished by entering step-by-step instructions from the FilterTec Plus front
panel buttons. You can enter and control by using Run, Stop, Time, Direction, R-Step, R-Scan,
P-Step, P-Scan, V, and W commands to have the system perform changing rates and
pressures, even rotary selector valve positions for switching buffers or collection vessels. A
sample program is included in this manual. All alarms used in CONSTANT RATE and
CONSTANT PRESSURE Modes except Run Time are available in PROGRAMMABLE R-P
Mode.

SETUP: This operational mode allows you to select various user preferences and interface
options. The Setup: Scale submenu provides electronic balance options. Balances that can
interface with the FilterTec Plus must have bi-directional serial communication, and NOT have
internal calibration or be “delta-range” models. Many Mettler, Ohaus, and Sartorius balances
can be used. The Setup: Clock submenu allows the user to set the time and date used in the
display. The Setup: System Test submenu allows checkout of FilterTec Plus outputs and
requires purchase of a special set of connectors to perform the test. Setup: Test Mode
provides an additional mode to test the I/O’s independently. Setup: Ethernet is used to set the
IP Address, Subnet Mask, and Gateway for Modbus TCP/IP communications. Setup: Printer is
used for setting up the printer/PC communications parameters as well as print time interval and
the print delay. Setup: Analog defines the ranges, alarms and limits for the three analog
channels available for data acquisition and reporting of 4-20 ma signals from detectors
equipped with analog outputs. Setup: Temperature allows the input of an offset value if needed
for the temperature input. Setup: Press. Sensor is used to zero the pressure sensors, set the
units (psi, bar, kpa), and choose the source for the pressure control and alarms. Setup: Pump
allows you to set various pump user preferences, most importantly the Motor RPM. Setup:

Scale2 and Scale3 are similar to Scale mentioned above.
MANUAL: Allows manual control of pump speed and direction, and will display the value of

sensor P1. This is very useful for initial testing to determine flow rate / pressure settings.
NOTE: CONSTANT RATE, CONSTANT PRESSURE, and PROGRAMMABLE R-P mode

Alarms and Printer parameters are not functional in the Manual mode.

2.0 CONSTANT RATE Mode: Constant Rate/
Pressure Filtration.

SUMMARY: In this mode the selected pump rate (filtration feed rate) is maintained throughout
the filtration process. The FilterTec Plus can then switch to a user selected constant filtration
pressure. The Pmaintain setting is chosen in the Alarm Enable: Hi-Pressure submenu to
cause this to occur. First select the pump tube size (#13, 14, 16, 25, 17, 15, 24, or 35) (Note:
the use of #18 is not recommended), and then select the pump rate in terms of ml/min, then set
the Hi-pressure Limit to the desired constant pressure. The FilterTec Plus feed rate can be re­calibrated by the utilizing the front panel star () key. (If you have changed the motor sub­assembly from the factory installed one, select the correct RPM of your new motor in SETUP:
PUMP: Motor RPM submenu. (The choices are 8, 160 or 600-RPM.)

Use “Up” and “Down” keys to make a selection, then press, “Select” to implement that
selection.

Pump Tubing: Select sizes #13, 14, 16, 25, 17, 15, 24, or #35, using “Up” and “Down” keys
for choice of pump tubing size, then press “Select”. Based upon selection, the FilterTec Plus
accesses factory installed calibration curves, which relate the pump output in ml/min. to pump
motor speed.

Response F: Response Factor setting. The Pump Response Factor = 100 is the default value.
Decreasing this Pump Response Factor will decrease the pumps responsiveness to pressure
changes.

Clear Cumul: Resets (Clears) the following counters in the system: CV = Cumulative Volume;
RT = Run Time; Q1 = Filtrate Weight.

Pressure Zero: Allows you to zero the filter backpressure reading for all 3 SciPres Disposable
pressure sensors, P1, P2 and P3. The FilterTec Plus must not be running when resetting
pressure sensor output, and the sensor must be plugged in. Do not use the SPAN key
unless instructed to do so by Parker Customer Service. This is used to calibrate the pressure
sensor output, and requires additional hardware.

Alarm Enable: Allows you to select alarm options for several alarm conditions. Four options are
available: 1. Off (Disable the Alarm); 2. Alarm Only (Enable an auditory alarm); 3. Pump Stop
(Stop the pump and provide an auditory alarm); or 4. PMAINTAIN which switches the FilterTec
Plus from Rate Control to Pressure Control at a user-defined limit and maintains that pressure
by adjusting the system’s motor speed.

NOTE: PMAINTAIN only exists as an option for the Hi-Pressure Alarm.
Alarm Limits: Used to assign alarm limits for several alarm conditions:

Cumulative Volume in milliliters;
Low-Flow in ml/min;
Hi-Temp in degrees Celsius;
Run Time in Hours: Minutes;

Hi-Pressure (filter backpressure) in psi;
Filtrate Weight in grams. (This alarm must

be enabled in order to obtain and display
the Filtrate Weight (Q1), and several values
calculated from it.)

Lo-Pressure (monitor system leakage)
in psi;

25

Hi and Lo-Pressure alarms are related to the Pressure Source chosen in SETUP: Press.
Sensor, Source. The Alarm condition is triggered when alarm limit is exceeded. Alarms are not

mutually exclusive. You may select any combination of alarms.
Pump Rate: Select pump rate in terms of ml/min, however first select pump tube size, see 2.1.

Pump Rate may be changed “on the fly” by pressing the Rate / Pressure key on the front panel,
making the change, and pressing ‘Select”.

26

2.1 Pump Re-calibration:

The FilterTec Plus contains a permanent calibration table for each of the nine (9) tubing sizes:
13, 14, 16, 25, 17, 15, 24 & 35. For a given pump tube size, the calibration table relates the
pump motor RPM with the pump output in terms of ml / min. However, the user can update the
FilterTec Plus pump calibration very easily. (Note: the use of #18 tubing is not recommended)

NOTE: The FilterTec Plus usually is configured with a 160-rpm motor, and uses the built-in
calibration curves for that motor.

If flow rate needs require, the FilterTec Plus is also available with either a 600-rpm or 8-rpm
motor. In order for the FilterTec Plus to properly display the correct flow rates and cumulative
volume when using these motors, access SETUP: PUMP: Motor RPM and select the
appropriate RPM for the installed motor. The FilterTec Plus will then implement the factory
installed calibration curves for that particular motor.

(This will have been done for at the factory prior to testing and shipping, and should only need
to be changed if a different motor subassembly is purchased and installed.)

In order to use this recalibration feature, first select (in EDIT) the pump tube size in use, e.g.
size #17, then select the pump rate, e.g. 250ml/min. Press the EXIT key and then the EXEC
key. FilterTec Plus will now show the following display:

SET: T17 PR: 250ml/m
Press RUN when Ready

With the tubing primed, the system is ready to recalibrate the #17 pump tubing. For calibration
purposes, pump water into a container, e.g. 1000grams, placed onto a top-loading balance with
no filter attached. Alternatively use a 1000ml volumetric flask.

Press the RUN key and begin dispensing. Press the STOP key (not EXIT) to stop pumping
when 1000 grams have been dispensed. Press the Star () key and the following display will
be shown:

DV:1000 AV:1000
Incr. Decr. Select

Adjust (increase or decrease) the AV (Average Volume) parameter to 1000, or whatever the
actual dispensed weight is, press Select, the calibration table for #17 pump tubing will be
updated.

Important: The selected calibration volume or weight should be 4+ times the selected pump
rate or greater. For example, if the selected pump rate is 250 ml/min. the minimum calibration
volume / weight should be between 1000 mls or grams.

Note regarding this and SciDoc: The FilterTec Plus system contains volumetric calibration
curves for various motor/head/tubing combinations that are factory installed. This value is
displayed and output to SciDoc as FF. In most cases the Pump Rate (FF) is merely a starting or
reference point, and the weight related data, Q1, & C1 are of greater importance. These are
measured values of the Filtrate Weight Collected (Q1) and Collection Rate (C1), and are used in
the Vmax data and Chart that are included in the SciDoc spreadsheet.

2.2 CONSTANT RATE Mode: Alarm Limits

SUMMARY: This section allows the assignment of limiting values for several alarm conditions:
Cumulative Volume (CV) (based on feed rate) in ml; Lo-Flow (LC) (based upon collection rate

in ml/min; Hi-Temp (HT) in ⁰C; Run Time (RT) in Hours: Minutes; Lo-Pressure (LP) (monitor
system leakage) in psi; Hi-Pressure (HP) (filter back pressure) in psi; Filtrate Weight (FQ) in
grams. Note: The alarm condition is triggered when the alarm limit is achieved. Alarms are
not mutually exclusive. You may select any combination of alarms. For critical alarms (i.e. Lo­Flow Alarm) you want the FilterTec Plus pump to stop (Pump Stop), for less critical alarm
conditions you may want to choose an auditory alarm (Alarm Only). Each alarm may be
disabled if not required.

Use “Up” and “Down” keys, then press “Select” to implement.
Cumulative Volume (CV): This alarm setting represents the total volume of process solution

(based on the feed rate) that is delivered when a balance is not in use. Use the Filtrate Weight
Alarm for this purpose if you are using a balance! For example: if you set the Cumulative
Volume Alarm to 10,000ml or 10 liters, the FilterTec Plus will either alarm and/or stop the pump
when 10 liters of filtrate has been sent through the filtration device. Default = 1000.

Lo-Flow (LC): At the end of the Constant Pressure portion of the process, this represents a
critical alarm condition. The FilterTec Plus will automatically decrease the pump rate to maintain
the selected Hi-Pressure Limit setting once the Pmaintain alarm has been triggered. The Lo­Flow parameter (ml/min) represents lowest collection rate before the pump shuts down, and is
based on the collection rate (C1) when a balance is used and the Feed Rate (FF) without a
balance. Default = 0.

Hi-Temp (HT): Used to monitor the temperature of the process solution, this will stop the pump
at the set limit. Default = 35.0 ⁰C

Run Time (RT): This alarm setting allows you to set a timer for the filtration of your process
solution. For example, if you set the Run Time Alarm to 01:30, then the FilterTec Plus will
provide an auditory alarm and / or stop the pump after one (1) hour and thirty (30) minutes have
passed. Default = 01:00.

Lo-Pressure (LP): Typically set 3-5 psi units below the Hi-Pressure setting. The Lo-Pressure
Alarm is triggered when a sudden filter backpressure drop occurs after rising above this setting.
Such a change in the filter backpressure usually indicates a significant system leak. This is a
critical alarm, set to Pump Stop. Default = 0.0.

Hi-Pressure (HP): If you have chosen the Pmaintain in Alarm Enable, this is the value at which
the pump will change from the Constant Rate method to the Constant Pressure method. Setting
the Alarm to Pump Stop creates a Constant Rate only process that will stop when the Hi­Pressure Limit is achieved. Default = 20.0 psi.

Filtrate Wgt. (FQ): The FilterTec Plus comes with a top-loading balance. Enter the filtrate
weight (grams) that you want to collect, and the FilterTec Plus will either alarm or stop the
system when the desired weight has been collected. Set this value beyond the balance capacity
if you do not wish it to trigger during normal use. (If the balance goes negative at the start of the
run, the 0 gm default could trigger this alarm.)

NOTE: This alarm must be enabled to at least “Alarm Only” in order for the Q1 (Filtrate
Quantity) to be obtained or displayed. Default Limit = 0.

3.0 CONSTANT PRESSURE: Constant Pressure
Filtration

SUMMARY: This FilterTec Plus mode allows implementation of a constant pressure filtration,
i.e. a user selected filter backpressure is achieved and maintained throughout the filtration
process. When the filter device starts plugging up, the FilterTec Plus detects a corresponding
increase in filter backpressure. In order to maintain the selected filter backpressure setting, the
FilterTec Plus will automatically decrease the feed rate. Thus the constant pressure function
of the FilterTec Plus allows use of a safe backpressure setting that is consistent with a high
filtrate flow rate.

This mode is also used to run Vmax tests for filter sizing tests.
Use “Up” and “Down” keys, then press “Select” to implement that selection.

Pump Tubing: Select sizes #13, 14, 16, 25, 17, 15, 24 or #35, use “Up” and “Down” keys for
choice of pump tubing size, then press “Select”. Based upon selection, the FilterTec Plus will
access factory installed calibration tables, which relate the pump output in ml/min. to motor
speed. FilterTec Plus output can also be re-calibrated by the utilizing the front panel star ()
key. (See Constant Rate Mode for information on flow rate calibration.)

Clear Cumul: Resets (Clears) the following counters in the “Exec” front panel display: CV =
Cumulative Volume; RT = Run Time; Q1 = Filtrate Weight.

Response F: Response Factor setting, 1 to 100. Increasing the Pump Response Factor will
increase the pumps responsiveness. Default = 100.

Pressure Zero: Allows you to zero the backpressure readings of all 3 SciPres pressure
sensors. The FilterTec Plus must not be running when resetting pressure sensor output, and the
sensor must be plugged in.

DO NOT EXCEED THE MAXIMUM PRESSURE OF 60 PSI FOR THE SCIPRES SENSORS
OR DAMAGE TO THE SENSOR MAY OCCUR.

Alarm Enable: Allows you to select alarm options for several alarm conditions. There are three
options available: 1. Off (Disable the alarm); 2. Alarm Only (Enable an auditory alarm); 3.
Pump Stop (Stop pump and provide an auditory alarm). All alarms trigger when user defined

alarm limits are exceeded.
Alarm Limits: Allows you to assign alarm limits for several alarm conditions:
Cumulative Volume in ml;

Hi-Temp in degrees Celsius.
Run Time in Hours: Minutes;
Lo-Pressure (monitor system leakage) in psi;
Lo-Flow (high filter backpressure) in ml/min

based upon collection rate;
Pump Pressure: Allows you to select filter backpressure (30psi, max. recommended) for your

filtration application. The FilterTec Plus will maintain the selected setting throughout the filtration
process. Pump Pressure may be changed “on the fly” by pressing the RATE/PRESSURE key
on the front panel, making the change, and pressing the ‘Select’ button. Do not exceed the
pressure rating for your filtration device; consult the the filter manufacturer specifications.
Select a safe backpressure that also maximizes your filtrate flow rate.

NOTE: The Source chosen in SETUP: Press. Sensor, Source i.e. P1, P2 or P3; or is the
pressure that will be controlled by this setting.

Filtrate Quantity in grams. (This alarm must
be enabled in order to communicate with the

3.1 CONSTANT PRESSURE: Alarm Limits

SUMMARY: This section allows you to assign limiting values for several different alarm
conditions: Cumulative Volume (CV) in milliliters; Hi Temperature in ⁰C; Run Time (RT) in
Hours: Minutes; Lo-Pressure (LP) (monitor system leakage) in psi; Lo-Flow (LC) (pump will
stop when collection rate falls below this limit) in ml/min.; Filtrate Quantity (FQ) in grams. Note:
The alarm condition is triggered when the alarm limit is achieved. Alarms are not mutually
exclusive. You may select any combination of alarms.

For critical alarms you may want the FilterTec Plus pump to stop (Pump Stop). For less critical
alarm conditions you may want to choose an auditory alarm (Alarm Only).

NOTE: The Lo-Pressure alarm is directly related to the Source chosen in SETUP: Press.
Sensor, Source, i.e. P1, P2, etc.

Use “Up” and “Down” keys, then press “Select” to implement selection.
Cumulative Volume (CV): This alarm setting represents the total volume of process solution

that is delivered through your filtration device when no balance is in use. Use the Filtrate

Weight Alarm for this when a balance is in use! For example: if you set the Cumulative
Volume Alarm to 10,000ml or 10 liters, the FilterTec Plus will either alarm and / or stop the
pump when 10 liters of solution has been delivered through the filtration device.

Hi-Temp (HT): Used to monitor the temperature of the process solution, this will stop the pump

at the set limit. Default = 35.0 ⁰C
Run Time (RT): This alarm setting allows you to set a timer for the filtration of your process

solution. For example, if you set the Run Time Alarm to 01:30, then the FilterTec Plus will
provide you with an auditory alarm and / or stop the pump after one (1) hour and thirty (30)
minutes have passed. This allows you to define the processing time, i.e. the time required to
obtain a desired filtrate yield.

Lo-Pressure (LP): Typically set 3-5 psi units below the Pump Pressure setting. The Lo­Pressure Alarm is triggered when a sudden filter backpressure drop occurs after rising above
this setting. Such a change in the filter backpressure usually indicates a system leak, i.e. pump
tubing has slipped off the filter connection.

Lo-Flow (LC): For constant pressure filtration, this represents a critical alarm condition, and
should be set to Pump Stop in Low-Flow Alarm Enable. In this operational mode, the FilterTec
Plus will detect any filter backpressure increases in the source pressure sensor (due to slow
filter plug-up) and automatically decrease the feed rate to maintain the selected Pump
Pressure setting (see 3.17). The Lo-Flow parameter (ml/min) represents lowest pump rate
before the pump shuts down. The Lo-Flow parameter should be set just below your desired
minimum collection rate.

Filtrate Qty. (FQ): The FilterTec Plus comes with a top-loading balance. Enter the filtrate weight
(grams) that you want to collect, and the FilterTec Plus will either alarm or stop the pump when
the desired weight has been collected. Set this value to zero if you do not wish it to trigger
during normal use. The maximum value is 99,999 gm. (100Kg).

NOTE: This alarm must be enabled in at least “alarm only” mode in order for the Q1
(Filtrate Weight) to be obtained or displayed.

4.0 PROGRAMMABLE R-P: How to generate
a PROGRAMMABLE R-P program.

SUMMARY: In PROGRAMMABLE R-P Mode you can generate a program that changes flow

rates or controlled pressure rates in a stair-stepped (STEP) or ramped (SCAN) manner over
time. If you wish, you can also control a pair of rotary selector valves, or repeat the program
automatically.

When generating or editing a Programmable R-P program, all program statements that you
want to see implemented during a specific timing block or interval

statement for that block.

RUN, and 003 RATE are all implemented at the beginning of the first timing block defined by
program statement 004 TIME: 00:05 (five minutes).

CW, Pump Direction: This program statement is implemented by pressing the front panel key

with the double arrows. This key functions like a toggle switch and allows you to select either
CW (clockwise) or CCW (counter-clockwise) pump direction.

RUN: This statement is implemented by pressing the front panel key labeled “RUN”, it instructs

the FilterTec Plus to turn on the motor.

hours:minutes. All preceding program statements are implemented at the beginning of this TIME
statement.

STOP:

instructs the FilterTec Plus to turn off the motor.

RATE, R-Step, R-Scan: Press “RATE” key then select RATE by pressing the “A” button. Select

R-Step to set a flow rate to be maintained for a given Time period. Select R-Scan to set a flow
rate to be scanned (ramped) up or down to over a given Time period. Please be sure that the
selected flow rate does not exceed the capacity of the installed pump head /motor combination.

PRESSURE, P-Step, P-Scan:

button. Select P-Step to set a pressure to be maintained for a given Time period. Select P-Scan
to set a pressure to be scanned (ramped) up or down to over a given Time period. The
controlled pressure is the one specified in SETUP, PUMP, Press. Sensor, Source.

Editing the program is accomplished using the “NEXT” “DELETE” and “LAST” keys. NEXT
moves to the next line in the program, LAST moves to the previous line in the program, (i.e.
backspace) and DELETE removes the line of the program currently displayed. To remove and
replace a command, press “DELETE” and “LAST”, and then input the new command.

This statement is implemented by pressing the “STOP” key on the front panel. It

Press “RATE” key then select PRESSURE by pressing the “C”

followed by selecting “Rotary Valve”. Six rotary valve positions for valve “V”, namely, V1 thru V6,
as well as, six rotary positions for a second valve “W”, W1 through W6, can be selected.

COUNT: Allows you to repeat the program automatically, and not generally used. Press star (*)

key, then select “SAMPL COUNT”, then select “1” if you want your program to run only once,
select “2” if you want to run your program twice, etc

Pressure Sensor is used to configure settings related to the SciPres Disposable Pressure

Sensors. The following can be configured; Range, Units, Source (control and alarms), Filter
(signal noise) and Zero/Span.



Range: Set the overall pressure range, the Default is 60.0 psi, and is the maximum.

Changing this setting requires re-calibration of the sensor signals.



Units: Select between Psi, Bar, and KPA. Default = Psi.
Source: Controls the source pressure sensor for control in Constant Pressure Mode, and



for all pressure alarms. Select between P1, P2 or P3. Default = P1



Zero: Used to “Zero” the sensors to establish the zero offset cause by the circuitry and any

inherent hydraulic pressure in your tubing beyond the pump head. Connect the sensor, and
remove any pressure from the system. Select the sensor, P1, P2 or P3 and press “Zero”.
You are prompted to confirm the action. “Span” should not be used on a routine basis, as it
sets the max input value. NOTE: Do not Zero P1, P2 or P3 unless a sensor is connected.
The display should read “--.-“ with no sensor connected. If it reads 0.0 in this state, connect
the sensor and re-zero it.



Filter: This feature filters out the pulsations in the pressure signal due to the peristaltic

nature of the pump head. This provides better control and easier to read values, as
well as improved graphed data. Select from 1 to 7, 1 = no signal filter, 7 = maximum filter.
Default = 4.

52

5.7 Setup: Pressure Sensor, Calibration

The FilterTec Plus has built in calibration curves for the SciPres disposable pressure sensors
that are inherently very accurate for the installed default range of 0 – 60 psi, and there should
be no need for you to change it. If your metrology department insists that they calibrate them
periodically, the procedure follows.

To calibrate the FilterTec Plus / SciPres Disposable Sensors:

1. Obtain a NIST traceable regulated source of compressed gas (i.e. air, nitrogen) and
pressure gauge.

2. Go to Mode Select; Setup; Pressure Sensor, then to Pressure: Range, and note the range
specified, change if desired. (Default is 60 psi.)

3. Press Exit and scroll to Pressure: Zero.

4. Choose P1.

5. With no pressure on the sensor, press Zero (“A” button).

6. Connect regulated pressure source to P1, and carefully increase to match range noted in
step 2.

NOTE: Pressurizing the SciPres Sensors beyond 60 psi can damage the sensor.

7. Press Span (“B” button).

8. Turn off pressure source, Press exit.

9. Repeat steps 5 – 8, choosing P2 and then P3.

10. You have now recalibrated (spanned) all 3 SciPres sensors. It is still advisable to zero each
sensor again with no pressure in the system, prior to running your tests via the Edit: Press.
Sensor menu in the operating mode of choice.

and/or pressure can be adjusted in terms of % motor speed while the pump is running. Just
press the “RATE” key, make the appropriate adjustment, and press “SELECT”.

Manual Mode.

7.0 Data Acquisition:

Summary: Parker has available a software package called SciDoc that includes data collection

software and a Custom Excel spreadsheet that is automatically populated when any of the
modes are executed except Manual. It also has charts that are automatically populated as the
data is generated. See Section 7.1 below.

Either the Printer Port or USB Port may be used for data collection. The instructions for
installing the USB driver appear at the beginning of this manual. The FilterTec Plus Printer Port
is required for use with a serial printer, and both Thermal and Dot Matrix are available. By using
both ports, the data can be simultaneously captured on a PC and a Printer.

When a PC is connected, all data generated in RATE, PRESSURE, and STEP-SCAN modes
can be sent to the PC for archiving. Please use the Parker SciDoc Data Collection Software
described below. Alternatively, a PC running “HyperTerminal”, a program that comes with
Windows, may be used to capture the data. The HyperTerminal settings are provided for you in
section 7.2 entitled “PC HyperTerminal Settings.” When interfacing with a PC you will need a
separate RS-232 cable (P/N: 080-073) or USB cable (P/N: 090-158)..

NOTE: For a successful hook-up with your PC, the FilterTec Plus and the PC must use the

same communications protocol. Make sure that the communication parameters in Setup: Printer
are the same as those listed in for HyperTerminal below or the default values.

The FilterTec Plus is also equipped with a USB port that can be connected to your PC. You will
find the driver for this connection on the CD this manual came on. You will need to look in
Device Manager on your PC to determine the Com Port number assigned to the FilterTec Plus.

The FilterTec Plus is also equipped with an Ethernet Port. Settings for the Ethernet connection
are described in section 5.4. This is for communication via Modbus TCP/IP, and when the
register list is available, it will be added to the manual as an appendix.

56

7.1 FilterTec Plus SciDoc Data Collection Software:

SciDoc is a software package that captures the data output of the FilterTec Plus and places it in
an Excel spreadsheet. This spreadsheet also performs some basic calculations and populates
several graphs to aid you in the analysis of your process. It consists of a copy of WinWedge32
from TalTech Inc. and a custom spreadsheet with built in macros. It requires the use of a Parker
RS-232 cable, (P/N: 080-073) or USB cable, (P/N: 090-158) to connect your FilterTec Plus to an
available Com Port on your PC.

Minimum system requirements for are Windows 98 and Excel 2000. WinWedge32 v3.4 is
included in the package and is Vista compatible. Installation instructions are included with the
package.

Once installed, click on the shortcut for the spreadsheet, and the following dialog box is
presented:

If you do not get this screen, you will need to change the Macro Security settings in Excel.
If it does not prompt to enable macros or does not prompt for the COM port, the security level is

too high.

1. If using a version of Office older than 2007, from the Excel menu bar, click on Tools,
Macros, and Security. Set it to Medium, close the spreadsheet and re-launch it.

2. If using Office 2007, from the Excel window, click on the Office logo in the upper left corner.
Then click on Excel Options in the lower left of this window. Highlight the Trust Center, and
click on Trust Center Settings in the lower left.

a. In this window you have two options:

i. Click on Trusted Locations, then Add new location, browsing to the Winwedge

folder where the spreadsheet is located and making it a trusted location.

ii. Click on Macro Settings, and choose Enable all macros.

Choose the Com Port the FilterTec Plus is connected to.
Click on the OK button and WinWedge32 will start,
showing itself as an icon in your system tray.

If you chose cancel on the Setup dialog box, WinWedge32 won’t be in the system tray, and you
will need to click on the “Com Port Setup” button to complete this task in order for data
collection to be possible. Once this is complete, you will have the next dialog box:

57

Here the data sheet is setup for the mode being used and the number of pressure sensors in
use.

As this spreadsheet is also used for the FilterTec, options for one, two or three balances exist.
Setting it for less than three will not affect the data received; there may be columns of data that
are hidden.

Most common will be Constant Rate Mode and three Sensors. Choose the mode and either
one or three sensors and click on OK. These choices may be changed between runs if the need
arises by pressing the “Data Sheet Setup” button on the spreadsheet.

After pressing the ok button, the next dialog appears:

Enter the operator’s information and that of the filter and sample being run.

The Membrane area in square meters is a mandantory field, and must be filled in for Flux
calculations to function properly.

A default value of .000962 sq meters is entered for those using 47mm diameter filters. These
fields may be updated for later runs by pressing the “Operator Info” button on the spreadsheet.

58

After pressing OK, the empty datasheet appears:

When ready, press EXEC on the FilterTec Plus, and then RUN after the balance has initialized.
The data generated will automatically be placed in the cells of the spreadsheet, and the charts
populated with the same data. The text box in the upper left of the spreadsheet contains the
header information that is generated by the FilterTec Plus. This will list the Operational Mode,
the date and time, all operating parameters, alarm settings and alarm limits.

The following charts are included for use, and they may be viewed by clicking on the
appropriate tab at the bottom of the worksheet:

Filtrate Flow Rate (FF) and Pressure vs. Time
Filtrate Flow Rate (FF) and Filter Quantity(FQ) vs. Time
Vmax, which is T/W (seconds/gram) vs. Time (elapsed time, seconds)

Other charts may be created, or the existing charts may be modified if needed.

59

A couple items of Note: The columns that are visible on the spreadsheet will change
based on the mode, the number of sensors chosen, and the number of balances
chosen.

 Choosing three sensors will yield columns for P2, and P3.
 Choosing Programmable RP Mode will yield columns for the position of Valves V and W.
 Choosing multiple balances will yield columns for Q2, Q3, QT, C2, C3 and CT, which relate

to the Quantities collected on balances 2 and 3 as well at their Collection rates, and the
totals of both.

Appendix “A” Application

Examples

The FilterTec Plus allows filter capacity determinations to be are carried out by the
following methods:

1. Constant Pump Rate

2. Constant Pump Rate followed

3. Constant Pressure, V

max

4. Programmable Step/Scan Rate/Pressure

by Constant Pressure

The data obtained from these methods is used to determine optimal filtration conditions to
process a given volume of solution by dead-end filtration. The desired information includes
answers to the following questions:

a. What is the optimal filter porosity?
b. What is the required filter area?
c. What is the required filtration time?

FilterTec Plus Parameters: When utilizing the FilterTec Plus for filter capacity determinations,

a few, simple rules must be observed:

1. Selection of Pump Tubing: CP120, 160 RPM Pump Motor, Tandem 1081

The pump tube selection should be made based upon the desired / required pump output range.
Do not operate the FilterTec Plus at excessively low pump rates for any pump tubing you may
have selected. For example, the Masterflex tubing size #14 has an output range from 2.0 to 35
ml/min, however, pump rates below 10 ml/min are better implemented with #13 tubing because
its lower pump output capabilities and greater dynamic range. If you wish to implement a flow
rate of 5.0 ml/min, #14 tubing has remaining dynamic range from 5.0 to 2.0 ml/min (stalling
speed) where as #13 tubing has a remaining (ten-fold) dynamic range from 5.0 to 0.5 ml/min.

The dynamic range of the selected pump tubing is particularly important in the Constant
Pressure Mode (V

) as well as the Constant Rate/Pressure Mode. In both cases, the pump

max

output decay is monitored over time. In order to record the lower end of the pump rate decay
curve it is useful to utilize the widest possible dynamic range.

 For Pump Rates < 10 ml/min (160 RPM Motor) use Masterflex Tubing #13
 For Pump Rates 10 – 35 ml/min (160 RPM Motor) use Masterflex Tubing #14
 For Pump Rates 35 - 129 ml/min (160 RPM Motor) use Masterflex Tubing # 16
 For Pump Rates 129-283 ml/min (160 RPM Motor) use Masterflex Tubing # 25

* Depending on the filter porosity, filter material and filter housing, the Effective Filter Area may
differ substantially from geometric filter surface area.

63

The following diagrams show the various configurations of the FilterTec Plus system.

This is the most common setup, using a single filter and pressure sensor.

This is the other common setup, for testing a filter-train, using 3 filters and 3 sensors in series.

These may be augmented by use of a 6-way Rotary Valve to change from one solution to
another in a programmed manner, using the Programmable R-P Mode.

Appendix B: Troubleshooting

66

A. Peristaltic Pump Heads

When this occurs: Check the following: Possible Solution

When “Check Pump Head”
error occurs with your
peristaltic head.

When peristaltic pump
head turns, but no fluid
flows.

Does “Check Pump Head”
occur with no tubing in the
head?

Confirm the tubing sizes
you are using.

Check the tubing size and
pump head type, as you
may be using the wrong
size for that head.

Tubing Size is ok

If it occurs with no tubing in the
head, call Parker. You may
need a new motor.

If no, make sure you are using
the correct size tubing. Thick
walled tubing in a thin wall
pump head will cause this, and
may break the head

Tandem 1081 is for thin-walled
tubing, and 1082 is for thick­walled tubing. Thin-walled
tubing in a thick walled head
won’t produce much flow. Use
the correct size tubing.

The pump head may be
cracked from being forced
closed with the tubing
crosswise or the wrong size
tubing. Contact Parker for repair
or replacement parts.

When the pump head turns
ok with no tubing installed,
won’t turn when you put
tubing in, and you don’t get
a “Check Pump Head”
error.

The coupler is loose or
broken.

Contact Parker for tech support,
or to arrange for service and an
RGA#

67

When this occurs: Check the following: Possible Solution

When “Scale Error” “Hit any
key” shows on your screen.

Is your scale turned on, and
are the cables tight?

Ok, the scale is on, cables
are ok, and it still won’t
work?

Ok, the scale is chosen
correctly, and it still doesn’t
work. Now what?

Has someone messed with
your FilterTec Plus?

Press any key to clear the error,
tighten the cables, turn on the
scale, and try it again.

Refer to Section 5, Setup: Scale
of this manual, then go to Setup
Mode of the pump, select Scale,
then Scale Mfr, and confirm the
selection is correct.

Either refer to the same manual
section mentioned above to
check the scale settings, or call
Parker tech support for help
correcting them if you are not
using the default scale.

If someone other than yourself
or your supervisor has changed
the settings without your
knowledge, you can to return
them to their original settings.

When the pump is acting
weird. The flows and
pressures are all wrong; it
gets data from the balance,
but slows down way to
early; etc.

Have you had electrical
problems in the building
lately?

Power spikes and brown outs
can cause problems. Enter
Setup; Pump, and then select
Factory Reset. This step is a
last resort. This will return the
unit to the factory default values.
You will need to return to Setup;
Pump; Motor RPM, and verify its
setting, as well as Setup, Pump;
Pump Head to verify it as well.
Call Parker tech support if
needed.

B. Piston and Magnetic Gear Heads

When this occurs: Check the following: Possible Solution

If you believe the head is stuck

When was the last time you
had the head serviced?

When “Check Pump
Head” error occurs with
your piston or magnetic
gear head.

Are you pumping a gritty
solution, or one that can
crystallize if allowed to dry
out?

due to being dried out, you can
try wetting it by placing an
appropriate solvent in the upper
tubing overnight.

If it still won’t turn, contact
Parker to arrange an RGA to
send your pump in for service,
or purchasing a service kit if you
have a magnetic gear head.

When your piston pump
head seems to turn and
the motor runs, but no
fluid flows.

When your magnetic
pump head seems to turn
and the motor runs, but no
fluid flows.

Either the piston is broken,
or the coupler is loose.

Has the unit run dry?

Is it a high viscosity fluid?

Contact Parker for tech support
or to arrange for service for your
pump and RGA#

Magnetic gear head pumps do
not dry prime well after they
have been broken in. You must
keep the pump wet. Be sure you
are using a check valve as your
dispensing tip so the fluid
doesn’t run back into the
container.
Magnetic gear heads do not
perform well with viscous fluids,
as they can de-couple. Either
reduce the viscosity, provide
head pressure, or choose a
different style of head.

C. SciDoc Documentation Software

When this occurs: Check the following: Possible Solution

Check Device Manager from the
properties page of the My
Computer Icon. Expand the +
next to Ports, Com and LPT.
What Com ports exist, and are
they functioning properly?

If all in Device Mgr is fine, then
some other program is using the
Com Port, consult your IT or MIS
dept. for assistance. You may
have to specify a different Com
Port for use with the SciDoc
spreadsheet.

Known devices/programs that
cause this error:

 Installed but not used Serial

Mouse.

 RS-232 bar code reader

installed on the same Com
port.

 Hot Sync or Synchronize

program for your PDA.

 An already open instance of

SciDoc using that Com port.

When you get a “Device
Error, Com Port Not
Available” error from your
computer.

This is a computer related
error, not one generated by
the pump. The Com port
you specified is in use or
does not exist on your
computer

When this occurs: Check the following: Possible Solution

You have SciDoc open, and
the FilterTec Plus running,
but no data is being
collected.

70

There is no communication
between the spreadsheet
and the FilterTec Plus.
Check that you are using
the correct cable, and that
it’s installed correctly

WinWedge may not be
running.

WinWedge may not be able
to access the Com Port.

The RS-232 cable for the PC
can look nearly identical to that
used for the balance. They
should be labeled..

Check the System Tray for the
WinWedge Icon. If it’s not there,
click on the Setup Button, and
indicate which port you are
using.

You will find a button on the
Taskbar indicating a “Device
Error”, refer to the previous
troubleshooting subject for help
with Com Port errors.

D. FilterTec Plus Specific issues

When this occurs: Check the following: Possible Solution

Review suggestions for the
Is it connected and
configured correctly?

You have a balance in use,
but aren’t getting any data
from the balance.

Did you turn the Filtrate
Weight Alarm off?

“Scale Error” problem listed

above. If your not getting this

error, see #2 that follows.

If the Filtrate Weight Alarm

under Alarm Enable: Filtrate

Wgt. Is set to OFF, the unit will

not look for the balance, and not

gather data from it.

The lack of “Scale Initialization”

occurring is a good clue. Set

this alarm to either Alarm Only,

or Pump Stop. If you don’t want

the alarm to occur, set the Limit

to either 0.0 or well beyond

anything you might collect.

The pressure reading is
always 0.0, even when the
sensor is disconnected.

This occurs when the
sensor is Zeroed when not
connected, or Span is
pressed instead of Zero,
thereby setting the max
input to a zero value.

You must perform a Factory

Reset to correct this.

Following the Reset, verify the

Motor RPM setting, and be sure

to only Zero the sensors when

they are connected!

Do not use the Span button

unless the Pressure Sensor

inputs are being calibrated.
