Micatrone MF-PFA-PU Installation & Operation Manual

Micafl ex PFA-PU ver 3.
Pressure- and Flow transmitter with alarm
and purging function for fl ow sensor
NOTE !
Read through the entire manual before you begin
installation and programming.
APPLICATION
MF-PFA-PU is a microprocessor controlled transmitter/
controller for measurement of differential pressure or
fl ow. With the four keys on the front panel it is possible
to access all functions, make settings and scale the
output signal. The double row, 2x16 character, LCD
with backlight displays functions and values.
MOUNTING
MF-PFA-PU is designed for wall mounting but can
be fi tted with an optional frame kit, MFM-PANEL, for
recessed mounting on wall or through a cabinet door.
MF-PFA-PU is screwed to the wall using four screws,
max ø 4mm. Location of screw holes are shown on the
reverse of the enclosure.
Unscrew the lid and use the bottom screws to
temporarily fi x the lid on the upper edge of the
enclosure during installation. See fi gure.
OUTPUT SIGNAL
MF-PFA-PU has two analogue output signals which
can be used for pressure, fl ow or control signal. Each
output has three terminals, one for Volt DC, one for mA
DC and one common zero. The outputs allow both the
Volt and mA signals to be used simultaneously.
With activated purging function, the purging unit PU3
is connected to output 1 (Volt or mA). If the unit is fi tted
with built-in automatic zero-setting module MFM-ZP, it
is connected to output 2 (Volt or mA). It is still possible
to use the free output signal on both outputs for the
selected source.
ALARM
MF-PFA-PU has two alarms, each independent of the
other. Each alarm has it´s own voltage-free changing
relay output, acoustic beeper and LED indication for
pressure or fl ow, high or low alarm level and manual or
automatic reset.
START MENU
When the transmitter is connected to supply voltage, a
start menu is displayed.
Using the arrow-keys it is possible to scroll through the
different available start menus. To have the unit always
displaying the same start menu, it can be selected and
programmed in parameter group SYSTEM SETTINGS.
By pressing the ESC-key when other menus are
displayed the selected start menu is displayed.
