MFC-CB™ Operation and Maintenance Manual

[MFC] is used to select the MFC Profile for the active MFC-CB device channel.

When an optional MFC Switchbox is connected and activated on the current device

channel, [MFC] also specifies which Switchbox channel to use (see Section 3.4.6).

ATION

To select the MFC profile for the active MFC-CB device channel, press [MFC] from the

run screen.

If an optional MFC Switchbox is connected and

active on the active MFC-CB device channel (see

Section 3.4.6), when [M

FC] is first pressed the

screen prompts the operator:

Enter Switchbox channel <1>, <2>, <3>, <4> or <5> as desired.

If an MFC Switchbox is NOT being used, the first

display is:

The number refers to the MFC profile number (see Section 3.3.1, PRINCIPLE).

The

profile number shown is the last profile number used. Edit the profile number to the

desired profile and press [ENTER]. When the profile number is entered, a summary of

the profile is displayed. Press [ESCAPE] to back up and select a different profile.

Press [ENTER] to return to the run screen with the selected MFC profile active.

MFC-CB cannot operate with a different type of electrical signal on its two

device channels. Selecting an MFC profile whose electrical signal is different for the

electrical signal active on the other channel prompts a warning that confirming the profile

will cause the other channel to switch to the default factory profile that specifies the

same electrical signal as the profile being selected (#1 for voltage, #2 for current).

MFC profiles #1 and #2 are factory default profiles. #1 is for 0 to 5 V operation and #2 is

for 4 to 20 mA operation. These do not support operation in a flow unit. If you have not

yet set up any custom profiles, use profile #1 or #2 to operate. To set up custom MFC

profiles that include flow units, see Section 3.3.1.

Pressing [+/-] from a run screen causes an instant display of a summary of the MFC

profile that is active on the active device channel. This can be used for a quick check of

the characteristics of the currently active MFC profile.

MFC profile selections made using [MFC] are device channel specific. The set point

entered on one device channel does not affect the other channel.
