MF-PFTT
Instruction : mi-261gb_090212
NOTE !
Read the entire instruction carefully before start.
Application
MicaFlex PFTT is a pressure and flow transmitter
with built in PI-controller and a temperature input
which makes it possible to compensate flow mea
-
surement for temperature changes.
MF-PFTT can be programmed to activate a purging
unit, MF-PU-2, for automatic cleaning of flow sen
-
sors with compressed air on set intervals.
With the four key pad, ¹, ¸, PGM and ESC
, the de
-
sired function is selected as well as setting and scal
-
ing is done. The dual row LCD display clearly indi
-
cates the selected function.
Installation
MF-PFTT is designed to be placed on a wall or for
recessed mounting through a wall or cabin door.
When recessed mounting, a mounting kit,
MFM-PANEL is used. The unit is fixed to the wall by
four screws, max 4 mm. The location of the holes is
shown at the back of the enclosure.
Unscrew the four screws of the front cover and use
the bottom screws to attach the front cover on the
upper end of the casing, see Fig 2. This makes in-
stallation and electrical connection easier.
Connect power supply according to the electrical
connection.
To each front cover the CPU is mounted, since the
I/O calibration of the main circuit board is stored on
the CPU-board, it is not possible to move the front
cover between different units.
Output signal
MF-PFTT has two analogue outputs to be used for
actual value of pressure and flow, temperature,
purging unit or PI-control output for pressure or flow.
VDC or mA output signal must be set by the
DIL-switch (DIL1). The same programming must
then also be done under “Outputs”.
Basic programming instruction
When the power supply is connected a start menu
will be displayed. With ¹¸ it is possible to scroll
through the different start menus. To always have
the same start menu, the selection is programmed
under “System settings”. Pressing ESC when some
other menu is displayed returns to the menu pro-
grammed under “Display”.
Programming
Press PGM until "PROGRAM-MENU" appears. Re
