Micatrone Micaflex PFTT Installation & Operation Manual

Micafl ex PFTT ver 3.
Pressure- and Flow transmitter with
purging function for fl ow sensor
NOTE !
Read through the entire manual before you begin
installation and programming.
APPLICATION
MF-PFTT is a microprocessor controlled transmitter/
controller for measurement and control of differential
pressure, fl ow or temperature. With an external
temperature sensor, the fl ow measurement can be
compensated for variations in the temperature. With
an optional purging unit, PU3, the connected fl ow
sensor can automatically be purged with set intervals.
With the four keys on the front panel it is possible to
access all functions, make settings and scaling the
output signal. The double row, 2x16 character, LCD
with backlight displays functions and values.
MOUNTING
MF-PFTT 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-PFTT is screwed to the wall using four screws,
max ø 4mm. Location of screw holes are shown on the
backside 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-PFTT has two analogue output signals which can
be used for pressure, fl ow, temperature and control
signal. Each output has three terminals, one for Volt
DC, one for mA DC and one common zero.
With activated purging function, the purging unit is
connected to output 1 (mA) and the parameter (P10)
is hidden in the parameter list.
If the unit is fi tted with built-in automatic zero-setting
module, it is connected to output 2 (mA) and the
parameter (P13) is hidden in the parameter list.
ALARM
MF-PFTT has two alarms, each independent of the
other. The alarm is acoustic with beeper and visual
with LED indication for pressure, fl ow or temperature.
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
