Section 5

Certification Procedures for the Type A2 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). If the cabinet does
not balance within 5 units of the model-specific speed control setting shown
in Table 5-1, contact Labconco’s Product Service Department for assistance.

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 “Mute/OK” This will set the controller to its new value, and
change the display to the filter gauge mode.
