1.1 PRODUCT OVERVIEW

The MFC Switchbox™ can be used to connect a molbox1™ MFC control option or an MFC-CB™ control channel to up to five MFCs, or to one MFC and four MFMs. The rear panel of the MFC Switchbox connects to the molbox1 or MFC-CB via a circular 5-pin connector and a 25-pin DSUB connector. Cables are provided with the switchbox to facilitate these connections. A power cable is also provided. The MFC Switchbox contains its own power supply which allows it to maintain continuous power on all five devices under test (DUTs). The MFC Switchbox provides up to 55 watts of power. This allows it to provide 260 mA per MFC when fully loaded. MFCs typically require a maximum of 200 mA. Therefore, all five ports of the MFC Switchbox can be used simultaneously in most situations. Occasionally, when calibrating older, power hungry MFCs, it may only be feasible to connect four MFCs at a time.

The front panel of the MFC Switchbox has five 25-pin DSUB connectors. These connectors are used to connect the switchbox to the various DUTs.

Current controlled MFCs can only be used on channel 1. When testing MFMs, an MFC can be used for

controlling the flow in the test while taking the measurement data from the currently selected MFM. This controlling MFC must be a voltage based MFC.

3. OPERATION

33.

PPEERRAATTIIOON

3.1 OVERVIEW

The MFC Switchbox in and of itself does not require any special setup or configuration. It just needs to be connected to the molbox1 or MFC-CB and DUTs as described above, plugged in and powered on by actuating the power switch on the MFC Switchbox rear panel.

3.2 GENERAL OPERATION

Before using the MFC Switchbox the MFC profiles for the connected DUTs must be defined in the molbox1 or MFC-CB. This is accomplished using the setup function to define the MFC profile. For details on the MFC profile definition, see the molbox1 or MFC-CB Operation and Maintenance Manual. In order to support MFM calibrations using the MFC Switchbox the device type is specified to the MFC profile. After entering the MFC range, you will be prompted to enter the device type. The device type for any voltage based profile can be either ‘measure’ or ‘control’. If the profile indicates measure, then channel one will be used for control whenever the channel is selected that is associated with this profile. If the profile indicates control, then the selected channel will be used for both measurement and control.

When calibrating MFMs, the range of the MFC setup for channel 1 must be wide enough to cover the

range of all the MFMs being calibrated on the other channels.

For details on configuring the MFC channels and profiles see the molbox1 or MFC-CB Operation and Maintenance Manual. Once the MFC channels have been configured using the setup menu, the MFC channel can be selected by pressing the MFC function key on the molbox1 or MFC-CB front panel.

When the MFC function key is first pressed the screen prompts the operator to select the MFC channel (<0> disables).

The MFC Switchbox must be connected to the molbox1 or MFC-CB at the time of this selection, but does not have to be connected during the MFC setup described above. Entering <1>, <2>, <3>, <4> or <5> selects the corresponding channel on the MFC Switchbox and enables the MFC function. When not using the MFC Switchbox, select Channel #1 when activating the MFC function.

The operator is then prompted to select the MFC profile. The profile number that is associated with the selected channel is automatically displayed. This screen allows the operator to override the profile selection made during setup.

The number refers to the profile number. When the profile number desired is entered a summary of the profile is displayed. When [ENTER] is pressed again, the display returns to the main run screen and the MFC function is active using the MFC profile selected. The MFC Switchbox must be connected to the molbox1 prior to pressing [ENTER] or the message that actually triggers the switching inside the MFC Switchbox will be missed. With molbox1, the text <MFCn> or <MFMn> (where n is the channel number and the type depends on the channel configuration) will be displayed in the bottom right hand corner of the main run screen. With MFC-CB, the text <Dn,c> (where n is the number of the active MFC-CB channel and c is the number of the active MFC Switchbox channel.

When the MFC function is active, pressing [ENTER] from the main run screen or an MFC run screen allows entry and execution of the MFC setpoint command.

MFC SWITCHBOX USER’S MANUAL

When the selected channel is associated with a ‘measure’ profile type, the control signal is sent to the

device on channel 1. This setpoint must be set in voltage and will set flows according to the range specified in the profile for the device connected to channel 1. The measurements will be taken from the selected channel using the profile associated with the selected channel to define the flow value.

If the profile for channel 1 indicates a current based MFC, then attempting to select a channel with a

‘measure’ profile type will result in the error message <Voltage mode needed on channel 1 control>.

Pressing the [ð] arrow key any time the MFC control function is active causes an instant display of

the current MFC profile summary allowing a quick check of the characteristics of the currently active MFC profile. Pressing [ESCAPE] returns from MFC profile screen to the last run screen.

3.3 MFC PROFILES

MFC profiles are used by molbox1 or MFC-CB to configure the MFC function. MFC profiles define the analog signal range of the MFC or MFM and the relationship between the analog signal range and the flow range of the MFC or MFM. This information allows molbox1 or MFC-CB to operate with the correct signal for the selected MFC and to convert the MFC or MFM analog signals to the corresponding flow or % FS values, when desired.

MFC profiles are set up using [SETUP], <1MFC>. MFC profiles are stored by molbox1 and MFC-CB under profile numbers. This is the same number that will be used to select the MFC profile when the MFC function is activated using the MFC function key. Up to 26 MFC profiles can be defined and stored.

MFC profiles are designed to allow the user to set up the profiles of the MFCs that are typically used with so that they can be conveniently recalled from a lookup table when needed.

MFC profiles #1 and #2 are default profiles for working with the MFC function directly in analog units

without an MFC flow range or units. Profile #1 is 0 to 5 V, Profile #2 is 4 to 20 mA. When the MFC function is active with Profile #1 or #2 selected, the MFC units of measure will always be V or mA. The UNIT function selects the molbox1 flow measurement unit.

3.4 UNITS OF MEASURE

When using the MFC Switchbox with molbox1

When the MFC function is active, the molbox1 flow units of measure will always be the units of measure specified in the active MFC profile.

When the MFC function is active, the [UNIT] function key is for selection of the units of measure for the MFC setpoint and output. The choices available are <V> or <mA> (depending on the active MFC profile's analog range), % FS or flow. The % FS selection will cause MFC setpoint and output to be displayed in % FS of the MFC which molbox1 will calculate using the definition of analog range and flow range contained in the MFC profile. The <3flow> selection will cause MFC setpoint and output to be displayed in the flow units of the MFC using the definition of analog range, flow range and flow units contained in the MFC profile.

When using the MFC Switchbox with MFC-CB

Units of measure are set using [UNIT]. If MFC profile #1 or #2 is active, the only units available are V, mA or % FS. If an MFC profile that specifies a flow range (any profile >#2) is selected, the display unit of measure may be a flow unit. See the MFC-CB Operation and Maintenance Manual for additional information.
