which is on Analog Output (AO) Channel 1. The HART version has only one 4-20 mA
or AO channel.
Alarms
Discrete relay contacts energized on configurable events are optionally available. These
are isolated relays or SSRs also known as digital outputs or DOs on the MFT B-Series.
The maximum current, voltage and isolation specs are on the brochure/ product manual.
Display Orientation
The keyboard/display on the 454/504/534 may be mounted in any 90 ° orientation for
optimum viewing and keyboard access when mounted in the process. Disconnect the
power first then open the explosion proof lid. You simply unscrew the cross point screws
(2 or 4), move spacers as required then tighten back down (see photo below). The ribbon
cable for the display is long enough if not twisted up too much to rotate into any of the
four positions.
Navigating Menus
The MFT-B flow meter with 2.0 and later firmware has a new menu system that is
different than the 1.x versions of the firmware. The new menu system is intuitive and
easy to navigate. The 2.x model still uses the 2x16 LCD display and 20-key keypad as
shown below. Note, however, the keypad overlay for the 2.x model flow meters has
changed. The numeric keys are layed out similar to a telephone keypad with alphabetic
characters included with the numeric digits imprinted on the keys.
The primary keys on the keypad used
to navigate the menu system are the P,
D, L, E, and H keys. The remaining
keys are primarily used for data entry.
A PC/laptop running a terminal
emulator program such as TeraTerm
can be used instead of the onboard
keypad and LCD display. The
corresponding navigation keys on the
remote keyboard are the lowercase
(non- shifted) p, d, l, h keys and the
ENTER key functioning as the E key
on the meter keypad. The Table
below defines the functions of the
keys
