Introduction

Manual ContentsThis manual covers the installation, operation, maintenance, technical reference information and troubleshooting for the WAVEPOD instrument module manufactured by WAVE. To ensure proper operation of your WAVEPOD, please read this manual completely.

Equipment DescriptionThe WAVEPOD instrument module combines a number of instruments for use with Wave BioreactorTM disposable cell culture devices manufactured by WAVE. It can provide dissolved oxygen measurement and control; pH measurement and control; aeration control and O2/CO2 gas blending. The WAVEPOD consists of a stainless-steel chassis with a color touchscreen that provides a simple and intuitive user interface. Data communications to Wave Bioreactor base units are provided so that the bioreactor can be integrated with the instrumentation. A built-in Ethernet port provides a digital interface for data acquisition. Seven modules are available, four of which can be installed into the WAVEPOD at a time to provide the desired functionality. A WAVEPOD is designed to be used with a single Wave Bioreactor. Each bioreactor can hold 2 CellbagsTM; one WAVEPOD is required for each Cellbag. The bioreactor can be operated from the WAVEPOD touchscreen. If space is limited, one WAVEPOD may be stacked on top of another. The built-in color touchscreen provides complete information on installation, configurations, connections, utilities, communications, pumps and alarms.

pH CONTROLLERThe pH control module enables on-line control of pH in the Cellbag. This module is installed in BAY 1. A setpoint controller is provided to power BASE and ACID pumps on and off to maintain pH. The controller can operate WAVE PUMP20 units or user-supplied pumps. Alternatively, the CO2 concentration can be controlled (requires CO2 CONTROL option) to maintain pH.

DO (DISSOLVED OXYGEN) CONTROLLERThe DO control module enables on-line control of dissolved oxygen (DO) in the Cellbag. The DO control module is located in BAY 2. The controller monitors dissolved oxygen using an optical sensor and can be configured to vary the rocker speed to maintain the desired dissolved oxygen concentration in the Cellbag. Alternatively the controller can control the % O2 in the aeration gas to the Cellbag (requires O2 CONTROL option).

AIRFLOW CONTROLLERThe airflow control module is located in BAY3. It can be used as a standalone module for Cellbag aeration or as a conditioned gas supply to a WAVE Bioreactor20/50EHT unit. Air is aspirated from the AIR IN port on the module panel and pumped out the AIROUT port. The AIR IN port can be left unconnected to use ambient air or process air (0.2 BAR max) can be connected. The airflow is measured by a thermal mass flow sensor and regulated by a flow control valve operated by an internal controller. The AIRFLOW control module is required if CO2 or O2 modules are to be used.

WAVEPOD

CO2 CONTROLLERCO2 concentration is measured and controlled by the CO2 control module located in BAY4. The gas composition is measured by a Non-dispersive infrared (NDIR) CO2 sensor using a flow-through cell. The internal controller regulates CO2 gas to mix with air to produce the desired CO2 concentration in the gas to the Cellbag headspace. The CO2 sensor is temperature compensated (0 50 C). Pressure changes can influence the reading however, the gas flow is carefully regulated to maintain constant pressure in the CO2 sensor cell regardless of AIROUT delivery pressure or minor fluctuations in CO2 inlet pressure. Since the CO2 controller uses a CO2 measurement to control the composition, it is not necessary to use pure CO2 gas for control.

O2 CONTROLLERO2 concentration is measured and controlled by the O2 control module located in BAY 4. The gas composition is measured by a unique zirconium oxide sensor. The oxygen specific chemistry produces a signal proportional to the oxygen present in the flow through cell and microprocessor circuitry provides a linear and stable signal. The O2 sensor can be adjusted using ambient air and/or span gases. Unlike electrochemical sensors, O2 sensor does not degrade when not in use. Under typical operating conditions, the sensor should last 10 years. O2 using a flow-through cell. The internal controller regulates how much O2 gas to mix with air to produce the desired O2 concentration to the Cellbag headspace. The O2 sensor is temperature compensated (0 50 C). Pressure changes can influence the reading; however, the gas flow is carefully regulated to maintain constant pressure in the O2 sensor cell regardless of AIROUT delivery pressure or minor fluctuations in O2 inlet pressure. Since the O2 controller uses an O2 measurement to control the composition, it is not necessary to use pure O2 gas for control.

pH ControlFUNCTIONThe pH control module enables on-line control of pH in the CellbagTM. A setpoint controller is provided to power BASE and ACID pumps on and off to maintain pH. The controller can operate WAVE PUMP20 units or usersupplied pumps. Alternatively, the CO2 concentration can be controlled (requires CO2 CONTROL option) to maintain pH. The appropriate module must be installed in BAY1. Regardless of the sensor used, the pH control action is identical.

NOTE: The pH can also be adjusted using buffers. Remove the probe from the Cellbag. Place the probe in sterile buffer pH 7 and adjust the SPAN knob on the pH module. Place the probe in buffer pH 4 and adjust the SLOPE on the pH module. This operation must be done aseptically, and then the probe can be reinserted into the bag.

ELECTRODE pH SENSORThe pH module requires special combination electrode pH probe made by WAVE (PHPROBE) that can be inserted into a luer fitting provided on the Cellbag. These pH probes are provided sterile and must be inserted in an aseptic manner. They are also available sterilized and preinstalled in the Cellbag. The pH probe may be reused, resterilized chemically by complete immersion for a minimum of ten (10) hours in CIDEX (activated dialdehyde solution glutaraldehyde 2.4%). Reinstall probe aseptically.CIDEX is a registered trademark of Advanced Sterilization Products, a Johnson & Johnson Company.

MEASUREMENT THEORYpH is measured using an ultra-miniature combination glass electrode. This electrode is capable of long-term stable operation necessary for cell culture applications. NOTE: pHPROBE is packaged in a 3M NaCI 40% glycerol storage solution. Probes may be used directly from storage or the storage solution may be removed via a sterile wipe or rinsing with a sterile buffer of choice. DO NOT TOUCH THE PROBE TIP.

INSTALLATION AND ADJUSTMENT1. Power up the instrument. Connect the pH probe using the supplied cable to the jack on the front panel of the pH module. Since the WAVE pH probes are very consistent in performance from probe to probe, it is usually not necessary to adjust using two buffers. Instead, a single point adjustment using media and a single grab sample pH measurement is usually sufficient. 2. Fill the Cellbag with media and allow to equilibrate. Measure the pH by sampling the Cellbag and using an external calibrated pH meter. Adjust the SPAN potentiometer until the reading on the controller matches the grab sample reading. The SLOPE is adjusted at the factory and should not need to be readjusted. 3. The pH probe is now ready for use.

pH Control ScreenPressing the pH button (OVERVIEW screen) brings up the pH CONTROL screen.

Figure 28. pH Control Screen. pH PV (Process Variable): The measured pH is shown in the box labeled pH. pH Setpoint: The pH setpoint is shown in the box labeled SP. Pressing the setpoint brings up a data entry keypad. You can enter a new setpoint and press the ENT key to accept the new setpoint. The keypad does not permit data entry outside a preset range. Range is 5 to 9 pH units. pH ON/OFF: Pressing this button starts pH control. The button changes to green and displays ON. Pressing it again disables pH control and the button changes to red and displays OFF. CONTROL MODE: ACID/BASE or CO2/BASE - the pH controller can operate in one of two modes 1. Control by ACID/BASE pumps; or 2. Control by CO2 concentration. In the latter mode, the CO2 setpoint is remotely controlled, so that if the pH rises above setpoint the CO2 concentration of the gas to the Cellbag headspace is increased. If the pH drops below setpoint, then the CO2 level is decreased. If the CO2 reaches a minimum user-set limit, then the controller can automatically trigger a BASE pump to maintain pH. Trends: The pH is graphed over a 10 minute period. Press the TREND button to view the graph.

pH Control SetuppH controller parameters can be set from the SETUP menu -> pH. Access is restricted by password. Password 2050. pH parameter screen:

Figure 29. pH Control Setup Screen. Setting Deviation Alarms: Dev Alarm: If this parameter is set to OFF, then deviations from the setpoint will not be monitored. Default: On. Dev Limit: Set the pH deviation alarm deadband. A deviation alarm is triggered if the pH is different from the pH setpoint by +/- this amount. The deviation alarm is only active if DEV alarm is ON and the pH controller is ON. Range is 0.0 to 1.0 pH unit, Default: 0.05 pH. pH controller options: DBAND: Control action takes place if the pH is within the deadband. The deadband is defined +/- the setpoint. Increasing the setpoint will result in coarser control. Making the deadband too narrow will result in excessive chatter and poor control. Range is 0.0 to 1.0 pH unit, Default: 0.1 pH. CTIME: After each control action, the controller must wait for a defined cycle time (CTIME) in order to let the acid/base or CO2 change to result in a stable pH reading. If the CTIME is set too short, then the controller will overshoot. If it is set too long, then the pH may not be controlled properly and drift. The CTIME can be set by the user to match process requirements and acid/base strength. Range is 10 to 300 seconds, Default: 120 seconds.

WAVEPOD

25

Available Control Schemes:Two control schemes are defined, either can be selected by the user: ACID/BASE CONTROL: Change in pH outside the deadband causes the acid or base pump to come on as needed. The amount of time the pumps are on depends on the magnitude of the pH difference and the GAIN. The pump then stays off for the remainder of the cycle time (CTIME parameter). The gains can be adjusted to compensate for the buffering capacity of the media and the acid/alkali strength. ACID GAIN: Higher gain results in the ACID delivery pump staying on a larger fraction of the cycle time for a given pH error (pH pH setpoint). Range is 1-999, Default: 100. BASE GAIN: Higher gain results in the BASE delivery pump staying on a larger fraction of the cycle time for a given pH error (pH pH setpoint). Range is 1-999, Default: 100. CO2/BASE: The controller responds to change in pH outside the deadband by changing the CO2% setpoint. This option requires that the CO2 control module by installed, supplied with CO2 gas and be turned on. The AIRPUMP must also be ON. A low pH will result in a reduction in CO2 concentration. The concentration is adjusted by CO2STEP every cycle time to give the headspace sufficient time to equilibrate. The maximum and minimum CO2% concentration in the gas supplied to the headspace can be set by the user. An alarm is set when either of these limits are reached. If the CO2% is reduced to the minimum concentration then the BASE pump control is activated to continue pH control as needed. The amount of time the pump comes on depends on the magnitude of the pH difference and the GAIN. The pump then stays off for the remainder of the cycle time (CTIME parameter). The gains can be adjusted to compensate for the buffering capacity of the media and the acid/alkali strength. CO2STEP: This is the amount by which the controller changes the CO2 setpoint at each cycle. Range is 0.0 to 2.0% CO2, Default: 0.5%CO2. MINCO2: The controller does not reduce the CO2 setpoint below this limit. Range 0.0 to 15.0% CO2, Default: 0 MAXCO2: The controller does not increase the CO2 setpoint above this limit. Range 0.0 to 15.0% CO2, Default: 15%.

ACID/BASE OPERATIONFor stable pH control it is necessary to cycle the addition pumps so that the acid or base has sufficient time to mix properly. The pH controller has a preset factory cycle time of 10 seconds. Part of this cycle is the ON time when the acid or base pump is energized. For the remainder of the cycle, the pumps are OFF and the controller waits until the cycle time is complete. If, at the end of the cycle, the pH is still not at the setpoint, the controller initiates another ADD/WAIT cycle. If the pH is at the setpoint, no further action is required. A small dead band around the setpoint is used to prevent excessive pump chatter. The cycle time can be adjusted if the system requires more mixing time. The amount of acid or base added per cycle is proportional to the difference between the setpoint and the actual pH. The GAIN constant adjusts the sensitivity. This GAIN can be increased if insufficient acid or base is being added per cycle. It can also be decreased if very concentrated acid or base is being used and significant overshoot is observed.

CONNECTING THE BASE PUMPThe BASE PUMP is used to add base to raise the pH in the Cellbag. It can be switched on and off automatically by the pH controller to maintain a constant pH equal to the setpoint. 1. Switch power on to the controller. Select the ACID/BASE control mode (SETUP menu). Set pH controller parameters as desired. 2. A peristaltic base pump such as the WAVE PUMP20 can be controlled by the pH controller. Plug the PUMP20 base pump to the jack marked PUMP2 on the rear panel of the WAVEPOD using the supplied cables. 3. Make sure that the pump direction is correct and turn all local switches on. Route the base tubing through the pump and connect to the Cellbag container. Open all valves. 4. Set the desired pH setpoint on the controller and press the pH controller ON button to activate acid/base control. 5. The BASE pump will turn on whenever the pH drops deadband units below the pH setpoint.

CONNECTING THE ACID PUMPThe ACID PUMP is used to add acid to lower the pH in the Cellbag. It can be switched on and off automatically by the pH controller to maintain a constant pH equal to the setpoint. 1. Switch power on to the controller. Select the ACID/BASE control mode (SETUP menu). Set pH controller parameters as desired. 2. A peristaltic acid pump such as the WAVE PUMP20 can be controlled by the pH controller. Plug the PUMP20 acid pump to the jack marked PUMP1 on the rear panel of the WAVEPOD using the supplied cables. 3. Make sure that the pump direction is correct and turn all local switches on. Route the acid tubing through the pump and connect to the Cellbag container. Open all valves.

4. Set the desired pH setpoint on the controller and press the pH controller ON button to activate acid/base control. 5. The ACID pump will turn on whenever the pH rises deadband units above the pH setpoint.

CO2/BASE OPERATIONAlternatively, it is possible to control the pH of suitably buffered media by changing the CO2 concentration of the headspace gas in equilibrium with the media. This second control mode (selectable form the SETUP menu) will make step changes in CO2 concentration to maintain pH. If the CO2 setpoint is reduced to a user-defined minimum limit, then the controller will automatically shift to BASE pump control as described earlier.

CONNECTING THE BASE PUMPThe BASE PUMP is used to add base to raise the pH in the Cellbag in the event it cannot be adjusted anymore by lowering CO2 concentration in the headspace. It can be switched on and off automatically by the pH controller to maintain a constant pH equal to the setpoint. 1. Switch power on to the controller. Select the CO2/CO2MIX control mode (SETUP menu). Set pH controller parameters as desired. 2. A peristaltic base pump such as the WAVE PUMP20 can be controlled by the pH controller. Plug the PUMP20 base pump to the jack marked PUMP2 on the rear panel of the WAVEPOD using the supplied cables. 3. Make sure that the pump direction is correct and turn all local switches on. Route the base tubing through the pump and connect to the Cellbag container. Open all valves. 4. Set the desired pH setpoint on the controller and press the pH controller ON button to activate CO2/base control. 5. The BASE pump will turn on whenever the pH drops deadband units below the pH setpoint and the CO2 controller setpoint is at preset minimum limit.

CONNECTING THE CO2 CONTROLLERThe CO2 controller can be given a remote setpoint to maintain constant pH in the Cellbag. 1. Switch power on to the controller. Select the CO2/BASE control mode (SETUP menu). Set pH controller parameters as desired. 2. Connect CO2 gas to the CO2 controller (must be installed in WAVEPOD). Toggle CO2 control to ON to turn on CO2 control. Toggle AIRPUMP control to on to turn on the airpump 3. Set the desired pH setpoint on the controller and press the pH controller ON button to activate remote setpoint CO2 control. 4.

CALIB: Pressing CALIB brings up a probe adjustment screen. Trends: The DO is graphed over a 10 minute period. Press the TREND button to view the graph.

FUNCTIONThe DO control module enables on-line control of dissolved oxygen (DO) in the Cellbag. The controller monitors dissolved oxygen using an optical sensor and can be configured to vary the rocker speed to maintain the desired dissolved oxygen concentration in the Cellbag. Alternatively the controller can control the % O2 in the aeration gas to the Cellbag (requires O2 CONTROL option).

USING THE DOOPT PROBERemove a DOOPT-PROBE (dissolved oxygen optical probe) from its packaging. You can leave the probe in its protective tube until an adjustment is required. Connect the probe to the jack on the side panel. Make sure that the ridge on the plug is lined up with the notch on the jack. Push the plug in and twist to lock it in position. From the overview screen, press the DO OPT button. The DO display should show a DO reading. Press DETAIL to verify the signal quality. The error code should be 0, if not, refer to the Troubleshooting section of this manual for additional error code descriptions. CAUTION: DO NOT TOUCH THE TIP OF THE PROBE WITH YOUR FINGER OR ANY OBJECT. DO NOT ATTEMPT TO CLEAN OR DRY THE TIP WITH A CLOTH. SIMPLY SHAKE DRY.

ADJUSTMENT BEFORE USERemove the protective tube from the probe. Adjustment requires a two-point method: 1. Zero oxygen Open a new packet of zero oxygen calibration solution (product ZERO OXYSOLN available from WAVE). Dip the bare probe in to the liquid. Wait for the reading to stabilize, then from the DOOPT screen: Set the temperature adjustment to the ambient temperature: o Press T/COMP. Using the pop-up keypad enter the ambient temperature. Press ENT to accept the new value.

Next push the CALIB button. Push the Set 0% button. A popup window will display SETTING 0%. Once the adjustment is complete the popup window will vanish.

WAVEPOD

This sets the 0% oxygen point. Continue on to set the 100% point. Pure nitrogen gas (very low pressure) can be used in place of the zero oxygen solution.

2. 100% air Saturation: CALIBRATION FAIL If unit is not able to set the 0 or 100% points, a CAL FAIL message will appear. Retry the cal procedure and replace the probe and repeat. Remove the probe from the zero oxygen solution. Rinse the probe in water and shake dry. DO NOT TOUCH THE PROBE TIP OR ATTEMPT TO DRY IT WITH A CLOTH. Allow the probe to equilibrate in air. When the reading is stable in 1-2 minutes: Press CALIB again. Now press the Set 100% button. A popup window will display SETTING 100%. Once the adjustment is complete, the popup window will disapear.

This procedure sets the 100% oxygen point and completes the dissolved oxygen adjustment sequence.

REMEMBER TO SET THE TEMPERATURE COMPENSATION READING TO THE BIOREACTOR OPERATING TEMPERATURE.

Installation in BioreactorPREPARE,THE OXYWELLTMInsert this end of the DOOPT probe into Oxywell2 fitting Locate the Oxywell2 fitting on the Cellbag. Remove the luer cap from the fitting and discard. Remember the Oxywell2 tip inside the Cellbag is sealed so removing this cap does not impact sterility. Fill the Oxywells with distilled water using the fill kit provided with the DOOPTPROBE. Instructions are included with the probe.

INSTALL THE DOOPT PROBEAfter adjusting the DOOPT-PROBE, insert the probe carefully into the Oxywell2. Some older Cellbags have the original Oxywell fitting. This has a twin blue/white Y-connector. DOOPT cannot be used with this fitting. Please contact WAVE to get Cellbags with the Oxywell2 fitting. Secure the DOOPT-PROBE by tightening the luer connector. This also ensures that the probe is correctly seated in the fitting. The unique Oxywell2 sheath is an oxygen permeable diptube. This allows the DOOPT-PROBE to be removed and reinserted repeatedly without any danger of contamination. The Oxywell2 is completely sealed and allows only oxygen entry by diffusion through the silicone rubber tip.

FOR OPTIMUM ACCURACY readjust the probe after insertion into the bag. This is possible if the Cellbag has not been inoculated. With aeration and rocking, this should correspond to the 100% saturation point. Let the Cellbag equilibrate so that it is at the correct temperature and at 100% air saturation. SET THE MANUAL TEMPERATURE COMPENSATION TO THE TEMPERATURE OF THE CELLBAG AND READJUST THE 100% POINT AS FOLLOWS: Set the temperature adjustment to the bioreactor temperature: o o Press the displayed temperature compensation value. Using the pop-up keypad enter the bioreactor operating temperature. Press ENT to accept the new value.

Press CALIB, now press the Set 100% button. A popup window will display SETTING 100%. Once the adjustment is complete the popup window window will disappear.

It is critical to fill the Oxywell2 with distilled water to provide a response time (t90) of about 3-5 minutes (see Technical Reference section).

PROBE MAINTENANCE AND STORAGEThe DOOPT-PROBE can be reused for many months. However, due to photobleaching, the amplitude of the fluorescent reading will ultimately become too low for accurate measurement (< 2000). Increasing the sampling frequency will shorten the probe life. The DOOPT module monitors the signal amplitude automatically, and will warn the user when the probe should be replaced. Unlike polarographic probes that are prone to sudden catastrophic failure, the DOOPT- PROBE performance decays very slowly and provides ample warning before the probe becomes unusable. No polarization or warm-up time is necessary. Unlike electrochemical probes, the optical DOOPT-PROBE does not contain any buffer to dry out and does not need to be stored wet or refrigerated. The DOOPT-PROBE fiber tip and coating can be easily damaged. Avoid hitting the probe on any hard surface or prying or scraping the fiber tip. The white fiber optic cable is quite flexible, but excessive force or a severe bend can snap the cable.

WAVEPOD

35

EXTENDING PROBE LIFEProbe life depends on the number of cumulative oxygen readings that are taken. Reducing the frequency of measurement will increase life, conversely increasing it will shorten probe life. The sampling frequency is set by the factory to once every 10 seconds but can be changed by the user from 1 to 99 seconds: Press on the displayed SCAN time value and enter the new scan time using the pop-up keypad. Press ENT to accept the new value. The instrument will now operate at the new sampling frequency.

VIEWING PROBE PERFORMANCEDETAIL: Pressing DETAIL brings up a pop-up window that display various probe parameters, such amplitude and phase of the signal. This display is useful for troubleshooting and is shown in Figure 33. Amplitude: This window indicates the signal strength of the DO probe. The pH probe degrades with use over time. A reading over 2000 in the display window indicates a fully functional probe. When the reading is below 2000, the probe should be replaced. Phase: Refer to the Technical Reference section of this manual for a complete description of phase angle. Temperature: Indicates the temperature of the DO probe in the cellbag. Error Code: Refer to the Troubleshooting section of this manual for specific error descriptions in the Optical Dissolved Oxygen Error Codes Table.

DO CONTROLLER PARAMETERSDO controller parameters can be set from the SETUP menu -> DO. Access is restricted by password. Password 2050. DO parameter screen:

Figure 34. DO Control Setup Screen.

Setting Deviation Alarms:DEV Alarm: If this parameter is set to OFF then deviations from the setpoint will not be monitored. Default: On. DEV Limit: Set the DO deviation alarm deadband. A deviation alarm is triggered if the DO is different from the DO setpoint by +/- this amount. The deviation alarm is only active if DEV alarm is ON and the DO controller is ON. Range 0.0 to 10%, Default: 10 %sat.

DO controller options:DBAND (Deadband): Control action takes place if the DO is within the deadband. The deadband is defined +/- the setpoint. Increasing the setpoint will result in coarser control. Making the deadband too narrow will result in excessive chatter and poor control. Range 0.0 to 10%, Default: 5 % sat. CTIME: After each control action, the controller must wait for a defined cycle time (CTIME) in order to let the change result in a stable DO reading. If the CTIME is set too short then the controller will overshoot. If it is set too long, then the DO may not be controlled properly and drift. The CTIME can be set by the user to match process requirements and acid/base strength. Range 10 -999 seconds, Default: 300 seconds.

WAVEPOD

37

Available Control SchemesTwo control schemes are defined. Either can be selected by the user: SPEED: The controller responds to change in DO outside the deadband by changing the BASE rocking speed setpoint. This option requires that the BASE be connected and configured in the WAVEPOD. A low DO results in a increase in speed. A high DO results in a decrease in speed. The speed is adjusted by STEP rpm every (cycle time in seconds) to give the DO sufficient time to equilibrate. The maximum and minimum rocker speed limits can be set by the user. An alarm is set when either of these limits are reached. STEP: This is the amount by which the controller changes the rocker speed setpoint at each cycle. Range 0.0 to 10 rpm, Default: 2 rpm. MINRPM: The controller does not reduce the BASE speed setpoint below this limit. Range 2 to 40 rpm, Default: 5 rpm. MAXRPM: The controller does not increase the BASE speed setpoint above this limit. Range 2 to 40 rpm, Default: 40 rpm. NOTE: Extremely low speed and low angle settings on the BASE are not recommended. O2 Concentration Control: The controller responds to change in DO outside the deadband by changing the O2% setpoint. This option requires that the O2 control module be installed, supplied with O2 gas and be turned on. The AIRPUMP must also be ON. A low DO results in an increase in O2 concentration. The concentration is adjusted by O2STEP every cycle time in seconds to give the headspace sufficient time to equilibrate. The maximum and minimum O2% concentration in the gas supplied to the headspace can be set by the user. An alarm is set when either of these limits are reached. STEP (%O2): This is the amount by which the controller changes the CO2 controller setpoint at each cycle. Range 0.0 to 1.0%O2, Default: 1% O2. MIN %O2: The controller does not reduce the CO2 setpoint below this limit. Range 0.0 to 50.0% O2, Default: 21 % O2. MAX %O2: The controller does not increase the CO2 setpoint above this limit. Range 0.0 to 50.0% O2, Default: 50 % O2.

Oxygen ControlFUNCTIONThe O2 module is used to inflate and ventilate the Cellbag disposable bioreactors with air containing a variable O2 concentration. O2 from a pipeline or cylinder is connected to the O2 module. Air is drawn from the AIR IN port (airpump module) and mixed with the O2 (connected to O2 IN). An O2 sensor measures the O2 concentration and controls it to any user-specified value from 21 to 50%. The O2 conditioned air is pumped from the MIX OUT port into the headspace of the Cellbag to maintain bag pressure, and to provide oxygen. If an oxygen supply is not available, consider using the O2GEN oxygen generator available from WAVE.

OPERATIONNOTE: A GREEN indicator will be displayed on the O2 CONTROL screen if the O2 inlet pressure is sufficient for operation. A red indicator shows that the O2 pressure is too low for proper control. 1. Connect power to the instrument. Switch ON. Allow 5 minutes for the unit to warm up and stabilize. 2. Set the external O2 source (line or O2GEN) at max pressure of 0.7- 1.0 bar (10-15 psig). Connect it to the O2 IN inlet connector located on the side. The unit is equipped with an internal non-adjustable pressure regulator. 3. Leave the AIR IN port unconnected if you wish to mix ambient air with the O2 stream. You can connect process air to this inlet. External gas pressure MUST be regulated to between 0.1 and 0.2 bar (1 3 psig). 4. The O2/air mixture is pumped out from the MIX OUT port on the front panel. Connect this to the AIR IN PORT on the 2050EHT BASE unit. For standalone operation, the MIX OUT can be connnected directly to the inlet filter on the Cellbag. 1. Air with up to 50% O2 content can be produced by the O2 module. Controlling the O2 content is an effective means of improving oxygenation. The O2 uses a zirconium oxide O2 sensor to measure the actual O2 content of the gas mixture. A feedback controller and valve is used to regulate the O2 content to the desired value. Since the actual oxygen concentration in the mix is measured and controlled, it is not necessary to feed 100% oxygen to the O2IN port. Any oxygen containing gas can be used as the controller will draw in as much of this gas as needed to produce the desired mix. CAUTION: If the pressure at the MIX OUT port exceeds 3 inches water gauge due to blockage or obstruction of the air flow to the Cellbag, a red high pressure LED indicator starts blinking on the O2CONTROL screen. If the overpressure condition continues for longer than 1-2 minutes, the internal air flow valve shuts down preventing the pressure from rising higher . When the overpressure condition clears, the airpump resumes operation.

NOTE: If you wish to produce an oxygen mixture with concentrations below 21% (air), you can connect a nitrogen stream to the AIR IN port.

NOTE: High pressure alarm does not activate if the airpump is in remote operation.

ADJUSTMENTAERATION PUMP1. Connect a certified flow meter to MIX OUT. 2. Turn on the Airflow. Set the setpoint to 0.5 lpm. 3. Go to the O2MIX Screen. 4. Compare the flow reading on the flow meter to AIR PV on the CONTROL SETUP screen. The readings should be within +/- 0.1 lpm.

WAVEPOD

5. If the flow reading on the flow meter is higher than the AIR SP, increase the SCALING value. If the flow reading on the flow meter is lower, decrease the SCALING value. 6. Check the flow rate at different setpoints. 7. If the flow readings are not linear, contact WAVE for service.

O2 SENSORThe O2 sensor does not need to be adjusted. Over time (10 years typical) the sensor will decay and will need to be replaced. Adjustment can easily be checked by following this procedure: 1. Allow the unit to warm up 5 minutes before adjusting. 2. Verify that the O2 gas is NOT connected to O2 IN and the O2 control is turned off. 3. Turn on the Airflow. Set the setpoint to 0.5 lpm. 4. Go to the O2 Control Setup Screen. Make sure that the O2 Offset is set to 0.0%. 5. Verify that the O2 PV display reads 21.0% (+/- 0.2%). If the reading is not within tolerance, adjust the O2 offset. 6. Connect 45% Certified O2 gas to AIR IN. Set the flow to 0.5 1.0 lpm. 7. Verify that the O2 PV display reads 45.0% (+/- 0.2%). If the O2 reading is not linear, replace the sensor. For sensor replacement, please contact WAVE for return of the unit for service.

Connect it to the CO2 IN inlet connector located on the side of the unit. The unit is equipped with an internal pressure regulator requiring no user adjustment. 3. Leave the AIR IN port unconnected if you wish to mix in ambient air with the CO2 stream. Alternatively, process air can be connected. Process gas pressure MUST be regulated to between 0.1 and 0.2 bar (1- 3 psig). 4. The CO2/air mixture is pumped out from the MIX OUT port on the side panel. Connect this to the AIR IN PORT on the 2050EHT BASE unit. For standalone operation, the MIX OUT can be connnected directly to the inlet filter on the Cellbag. Air with up to 15% CO2 content can be produced by the CO2 module. Controlling the CO2 content is an effective means for pH control using media containing bicarbonate buffers. Increasing the CO2 content lowers the pH. The CO2 module uses a NDIR CO2 sensor to measure the actual CO2 content of the gas mixture. A feedback controller and valve is used to regulate the CO2 content to the desired value. NOTE: High pressure alarm does not activate if airpump is in remote operation. CAUTION: If the pressure at the MIX OUT port exceeds 3 inches water gauge due to blockage or obstruction of the air flow to the Cellbag, the red high pressure LED will start blinking. If the overpressure condition continues for longer than 1-2 minutes, the integral air flow valve will shut down preventing the pressure from rising higher.

TroubleshootingGENERAL PROBLEMSDisplay stays blankThe touchpanel should display the startup screen a few seconds after power up. If the startup screen does not appear, verify that you have power by checking the Ethernet status LED. If it is not lit then check the unit fuse and power cord.

Keep getting BASE NOT FOUND MESSAGEThis message is displayed momentarily on startup and if communications to the connected base are lost. If the message stays on then internal communications to WAVEPOD control modules have been lost. Contact WAVE service for assistance.

OPTICAL DISSOLVED OXYGENLow amplitude alarm Check that the DOOPT-PROBE is connected correctlyand ensure that the plug is secure. Cycle power to the instrument to reset. If warning persists, replace the DOOPT-PROBE. Check the DETAIL display for the signal amplitude. Less than 2000 indicate a bad probe.

Fluctuating reading Some fluctuation (+/- 5%), especially at high DO levelsis normal.

Probe adjustment is drifting The DOOPT-PROBE should be readjustedevery 2-4 days to compensate for drift. If the drift is greater than 10%, the probe should be replaced.

CO2 MIXDisplay shows 0.1 even in air The tolerance of the CO2 sensor is from 07.5%, +/- 0.38% CO2, so this reading is not unusual. If zero is suspect, then readjust the sensor as previously described.

CO2 reading keeps drifting down The CO2 gas supply pressure is too low. Check that the green CO2 inlet pressure light is lit. The CO2 supply pressure must between 10 and 15 psig. CO2 is not controlling properly Verify that CO2 is connected to the correctinlet port. Check that the Air pump is on and that the flowrate is between 0.1 and 0.5 liters/minute. Check that the CO2 switch is ON. Check the setpoint on the controller.

No airflow reading Check that airflow to Cellbag is not obstructed. Verifythat the pump is working by disconnecting the MIX OUT coupling on the instrument.

Cellbag does not stay inflated Verify that there is airflow to the Cellbag. Check that the check valve on the Cellbag is correctly installed. Close off the Cellbag outlet using the pinch clamp and see if the Cellbag inflates. Then confirm that the check valve is working by connecting a short length of tubing to the check valve outlet and dip it into water. Tubing should be immersed to a depth of 5-10 mm. Opening the outlet pinch valve should cause bubbles to appear and bubbles should continue to flow as the flow and pressure stabilizes.

O2 MIXDisplay shows 21.4% O2 even in air The tolerance of the O2 sensor is from 21 to 40% O2, +/- 0.6%, so this reading is not unusual. If zero is suspect, then readjust the sensor as previously described. O2 reading keeps drifting down The O2 gas supply pressure is too low.Check that the green O2 inlet pressure light is lit. The O2 supply pressure must between 10 and 15 psig.
