and may overheat and damage the MOV which can fail in a short. Again, see the wiring
diagram 342038 for the specific alarm terminals.
Serial Communications
There are two independent serial ports on the MFT B-Series. A mini-type B USB
connector with Kurz driver
can act as a COM port so “remote” terminal operation is
possible or the RS-485 port can be used for the Modbus protocol and multipoint
communications. The USB port can be used in instead of the small LCD/keypad option
to view data, configure the meter or extract diagnostic data. The upload or download of
the meter configuration can be done on either the USB or Modbus port using the Kurz
provided program KzComm
. The advantage of the Modbus port is greatest when you
have multiple meters on the bus allowing access to all of them from one location, your
heated or cooled office or control room.
USB
Any terminal emulator program may be used to act as a remote terminal to the MFT B-
Series. HyperTerminal, which comes with all Windows versions except for Vista, is
sufficient and supports Xmodem for transferring and storing the MFT B-Series
configuration files. See below for Windows Vista. This takes about five seconds at 9600
baud, the only supported USB driver baud rate. The character format is 1 start bit, 1
stop, 8 data, and no parity. The program KzComm may also be used if you only need to
save/print the configuration files, but it is not a terminal emulator.
If HyperTerminal is not installed on your computer you may add it by going to the
Add/Remove Programs within the Control Panel and clicking the Windows Setup tab.
Then choose the Communication group and within it you will find the button to select
HyperTerminal. After this you may be asked for your Windows disk so this may be
installed. Refer to your Windows documentation if you need more information on
HyperTerminal. Once the program is installed, you start HyperTerminal which will
prompt you for a name of the connection, ie Kurz MFT B-Series, then an icon. Next you
select the communications port, ie COM 4 and finally you press Configure and set the
baud rate to 9600, data bits to 8, parity to none, stop bits to 1 and flow control to none.
Once you have verified this works, save the configuration under File, Save.
Windows Vista machines do not include HyperTerminal so you will need to download
and install it. This program is available for download from its designer at the following
