Security Lock
NOTE: The security lock automatically reactivates and locks out the
keypad every time the blower is shut off, by the keypad or by closing the
sash. After the initial auto diagnostic screen is cleared, the security lock
reactivates.
The security lock feature prevents operation of the Biosafety Cabinet by
unauthorized users. To engage the security lock, access the Security Lock
submenu, as described in the Logic Menu Instructions, Figure 4-5. Select the
“secure” option, and press the “OK” button. A ‘lock’ icon appears on the LCD
display. Once engaged, the operator must enter the proper sequence of keystrokes
to operate the cabinet. The proper sequence to unlock the Security Lock is:
Press the “▼” keypad 3 times within 2 seconds.
After successful entry of the unlock code, the lock icon disappears from the display,
and the user has full access to the keypad functions.
To disable the Security Lock, enter the Security Lock submenu and select the non-
secure mode. The lock is completely disabled.
