Pressure Controller Operating Instructions
General Description
These operating instructions are designed for the operation of the Pressure Controller used with
Labconco’s Precise Glove Boxes. The Pressure Controller performs three automatic modes on
the glove box. First, it cycles the purging/filling process in the main glove box chamber and
transfer chamber up to 199 cycles. Second, it regulates vacuum/pressure between -5 and +5
inches of water gauge in the main glove box chamber through the glove box pressure control
program mode. Third, it regulates vacuum in the transfer chamber between 0 and -29 inches of
mercury during the purging/filling process.
Models covered in these operating instructions:
5238600, Glove Box Pressure Controller, 100/115 volt, 50/60Hz
5238601, Glove Box Pressure Controller, 230 volt, 50/60Hz

Setup
Connect the Glove Box Controller using the Labconco connections/tubing kit #5245200 (ordered
separately). Follow the separate mechanical installation instructions included with the Pressure
Controller and also listed on pages 14 through 19 of these operating instructions. When
completed, the installed system should look like the diagram below.

Rear Panel Description
The rear panel includes the power inlet and circuit breakers, power on/off switch, the outlet
receptacle for plugging in a vacuum pump (the receptacle varies for 115 volt and 230 volt
models), and electrical connection for the glove box pressure control footswitch. The 4 electric
solenoid valves that provide control of the glove box Main Chamber gas in/gas out, and Transfer
Chamber gas in/gas out are also located on the rear panel. See the separate mechanical
installation instructions for plumbing connections to these valves. For your convenience, the
separate mechanical and plumbing installation instructions are also located at the back of these
operating instructions on pages 14 through 19.

Main Modes of Operation
The Labconco Glove Box Pressure Controller display has four main screens that provide access
to the 4 modes of operation listed below. The operation modes are covered in the next sections of
this document.
1.) Glove Box Pressure Control Mode
2.) Glove Box Purge and Fill Mode
3.) Transfer Chamber Purge and Fill Mode
4.) Setup Mode
Press the Mode key at the upper-left hand corner of the display screen to switch between each of
these four operation modes. Please be aware that if one of the glove box modes is
running/started, other glove box operation modes cannot be used. For example, if the Glove Box
Pressure Control mode has started (using the start key), the menu page for the Glove Box
Purge/Fill mode cannot be used – this prevents operational control conflicts from occurring at the
same time.

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 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 “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].
