3. When connected to the vessel inlet and outlet (closed flow mode), it can be used for suspension mixing (bubbling)
in anaerobic conditions.
Please note that PWM pump cannot be used simultaneously with magnetic stirrer as both need to be
connected to AUX1 on the rear side of the photobioreactor.

5.7.1 INSTALLATION
Instructions below explain connection of the PWM Pump with the Photobioreactor FMT150:
• The function of the PWM pump can be controlled manually by the front panel of the control unit and remotely
via Remote Control software for PBR FMT150. For manual operation via front panel please refer to appendix on
page 62 for more explanation. Briefly go to menu Setting > PWM_Mode. Here the PWM pump can be turned
ON/OFF and its performance can be adjusted in percentage of total power (10 % low power, 90 % high power).
• PWM Pump when connected to the PBR has to be set for REMOTE MODE operation to be directly controlled and
operated via Remote Control software for PBR FMT150. This pump can also be used in a manual mode as a stand-
alone instrument.
Note: When connected to the PBR and used In REMOTE MODE PWM Pump can replace the function
of the Bubble Interruption Valve.
• For REMOTE mode plug the grey connector cable to the PWM pump rear and connect it with the AUX2 connector
of the PBR FMT150. Set the speed control of the PWM Pump to REMOTE MODE position (Fig. 37B). PWM Pump
is now controlled via PBR FMT150 software.
• For the stand-alone MANUAL mode operation connect the PWM Pump power supply with the PWM Pump and
plug to AC outlet. The flow rate can be controlled manually with the speed control knob on the front panel.
Important: If MANUAL mode of the PWM Pump is used for controlling air bubbling in the cultivation
vessel, bubble interruption valve must be used to interrupt the bubbling during the measurements.
