CONTROL PANEL OVERVIEW (CONTINUED)
Automatic Start / Reset Switch
The all black Automatic Start / Reset switch initiates or aborts the pass box ’s auto vacuum-and-
gas-recharge cycle used to remove aerobic atmosphere from the pass box. Pressing then releasing
on the left (Start) the will initiate the auto cycle. Pressing and holding on the right (Reset) for three
seconds will abort and then restore the pass box to a near standard atmospheric pressure sufficient
that the pass box doors can be easily opened.
Pass Box Gas Light
This light indicates that the anaerobic mixed gas is being injected into the pass box during the auto
cycle. The pass box Gas light does not illuminate during manually gas injections.
VAC Light
The clear VAC pilot light indicates that the vacuum pump is in operation when the auto cycle is
vacuuming down the pass box chamber. The Vac Light does not turn on during manual
vacuuming.
Manual GAS / OFF / VAC Switch
The all black GAS / OFF / VAC switch allows the user to manually initiate a flow of AMG from the
GAS 1 IN port into the pass box by depressing the switch to the left. Pressing the switch to the right
activates the vacuum pump, lowering the atmospheric pressure inside pass box. A combination of
vacuum followed by injections of anaerobic mixed gas can be used to manually cycle the pass box
atmosphere.
Fuse
Located on the inside the power cord inlet on the back of the workstation, the fuse protects against
over current conditions. If the fuse blows, the BACTRON will shut down. For your safety and the
safety of laboratory personnel, the cause of a blown fuse should be determined prior to replacing it.
