LABCONCO CORPORATION 8811 Prospect Ave, Kansas City, MO 64132 (816) 333-8811, Fax (816) 363-0130, (800) 821-5525 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.
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. Labconco Operating Instructions 5242600, Rev.
Front Panel Description The front panel includes a large display screen and touchpad keys that are adjacent to the LCD display. The operation of these keys will be defined by text on the display screen (LCD). Each key may perform a different operation depending on the control mode selected. Labconco Operating Instructions 5242600, Rev.
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.
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.) 2.) 3.) 4.) Glove Box Pressure Control Mode Glove Box Purge and Fill Mode Transfer Chamber Purge and Fill Mode 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.
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.
Glove Box Purge/Fill – Operation Mode 2 The Glove Box Purge/Fill mode uses the same solenoid valves on the glove box that are used in the Pressure Control Mode. The Pressure Control mode will be temporarily suspended while a “Purge/Fill” command is being executed.
Transfer Chamber Purge and Fill – Operation Mode 3 The Transfer Chamber Purge/Fill mode controls the pressure exchange inside the transfer chamber. Pressure in the transfer chamber will be displayed inside the transfer chamber icon on the display screen. This operation mode controls the gas inlet and gas outlet solenoid valves connected to the transfer chamber.
Setup Menu – Operation Mode 4 Pressing the key opposite the word “Setup,” allows access to the setup operation mode. In the setup mode, the user may select their preferred units of pressure that are displayed, restore settings back to the default state, or calibrate the pressure sensors. The keys adjacent to the up and down arrows on the lower right of the display are used to select one of the three options. After toggling up or down, push the NEXT key to select the option.
Option 3 Calibration: The pressure sensors inside the controller can be calibrated using atmospheric pressure (single point calibration) or atmospheric pressure and a specific pressure level (two point calibration). Two point calibration provides increased accuracy; however, Labconco recommends that only the single point calibration be used because it does not require a calibrated pressure measurement standard. When “Calibration” is selected, the display screen below appears.
Back to Previous Screen Yes, All Doors Open To calibrate the pressure sensors for both chambers, the doors must be open so that atmospheric pressure is present at both sensors. This is the “zero point” for both sensors. Both pressure gauges on the glove box will also read “zero.” With both doors open, press the key adjacent to “Yes.” Once this is done, the following display screen on the next page appears: Labconco Operating Instructions 5242600, Rev.
Main Glove Box Chamber Select Key Transfer Chamber Select Key Back to Previous Screen Save Zero Point This display screen confirms that the doors are open and the sensors are ready for auto-zeroing. First, select the Main Glove Box Chamber key (Box) and wait for complete calibration to zero pressure. Next, select the Transfer Chamber key (CH) and wait for complete calibration to zero pressure.

Mechanical and Plumbing Installation Instructions NOTE: The Pressure Controller is configured to mount on the Glove Box. If your use is better served in the benchtop configuration, a benchtop mounting bracket (#5239100) can be ordered separately. Glove Box Mounting: Installation 1. Remove the two acorn nuts and lock washers as shown in Detail A insert. Place the Pressure Controller assembly over the studs as shown and secure with the previously removed nuts and washers. 2.
Benchtop Mounting: Installation (Detail B) 1. Disconnect the power source from the Pressure Controller. 2. Remove the Glove Box mounting bracket and attach the Benchtop mounting bracket. 3. Remove the eight screws that attach the Pressure Controller Cover to the Pressure Controller. Lift the cover straight up and set aside. 4. Remove the six nuts securing the Pressure Controller to the Glove Box bracket. 5.
Plumbing: Always install the polyvinyl tubing to the solenoid valves on the pressure controller before placing at the benchtop location. Refer to Detail C for valve inlet and outlet order. Glove Box Installation 1. The Pressure Controller has been pre-plumbed for installation in the Glove Box configuration. 2. Route the tubing to the Glove Box and Transfer Chamber as shown in Detail C. Note: Tube routing maybe dependent upon your application.
Benchtop Installation: With the Pressure Controller temporary located at the benchtop location proceed as follows. 1. Measure the distance between the solenoid valves of the Pressure Controller and the valves on the glove box. Cut the 3/16 ID tubing (the larger of the tubing in your kit) to the measured lengths. 2. The solenoid valves are embossed with IN or OUT port on the body of the valve, to indicate the direction of flow.
2. Bulkhead Fitting a. Locate the brass mini bulkhead fitting in your kit and install the fitting at the opening provided on the back wall of the glove box wrapper (see Detail E). 3. Glove Box Pressure a. Locate the line that comes from the pressure gauge (see Detail E ) to the fitting installed at the top of your glove box. This gauge is labeled on the front panel and is the one on your right when looking at the back of the front panel (see Detail E).
