Labconco Protector 50600 User Manual page 41

Glove Box Pressure Control – Operation Mode 1
The Pressure Control mode will allow the user to set a high pressure limit up to +5
inches water column and a low pressure limit to -5 inches water column [+/- 12.6
mBar or +/- 1245 Pacals]. Set these high and low pressure limits with the keys
adjacent to the "UP" and "DOWN" arrows on the display. Once these limits are
set, and the START/STOP key is pressed, the Pressure Controller will
automatically control the gas inlet valve, gas outlet valve, and the power to the
outlet receptacle for a vacuum pump. Pressure in the Glove Box Main Chamber
will be displayed inside the glove box icon on the display screen.

Manual control keys for evacuation "PURGE" and "FILL" (located along the bottom of
the display) will allow the corresponding valves to be controlled by the user to increase
or decrease the pressure inside the glove box. Note: These manual keys will not
operate the valves when the pressure is outside the limits of +/- 5 inches of water
[+/- 12.6 mBar]. A three-position footswitch is included with the Automatic Pressure
Controller. The footswitch provides manual foot control of the gas inlet and vacuum
outlet valves. The pressure inside the glove box will be displayed inside the glove box
icon on the display screen.
An audio alarm will actuate if the pressure exceeds the maximum limits of +/- 5 inches of
water. An "alarm reset" key (identified by the musical icon) is provided to mute this
alarm. The alarm will reset automatically when the pressure returns within +/- 5 inches
[+/- 12.6 mBar].
