Section 5
Certification Procedures for the Logic+
This section will outline test procedures to validate the performance of the Logic+.
Note: These are the only Labconco-approved test procedures for validating
the performance of the Logic+ Biosafety Cabinet. Other test procedures may
yield different or inaccurate test results.
NOTE: In order to properly certify the Logic+, you must obtain a Logic+
Certifier Kit, Labconco P/N 3858400. Qualified certifiers can obtain this kit by
contacting Labconco Customer Service Department at 800-821-5525.
Note: The ECM motor is programmed by Labconco to deliver a constant
volume of air throughout the life of the HEPA filters. Any changes to the
blower speed control should be small (less than 5 units).
Accessing the Certifier’s Menu
Note: You will need to access this menu to do any of the following:
Adjust the blower speed
To reset the filter gauge
To calibrate the optional airflow sensor

NOTE: The cabinet blower will automatically stop for approximately 60
seconds to zero the unit, and then automatically restart the blower. The
display will change to the speed setting mode. The number displayed is the
speed control setting, in this case a pulse width modulation (PWM) signal that
indicates the percentage of the motor’s duty cycle. The number should range
from 60 to 90 depending on the Logic+ model. To increase or decrease the
blower speed, press the
▲
or
▼
buttons, respectively. When the speed control
is set properly, press “
OK/Mute
” This will set the controller to its new value,
and change the display to the filter gauge mode.
