11.5.8 Temperature Sensors
Up to six spot temperature elements can be connected to the REX
transmitter if the Temperature Multiplexer Card (TMC) is installed. The
TMC board must be configured in accordance with the type of sensor
that is used (see chapter 4.1.8 in the REX Service Manual for detailed
instructions on how to configure the TMC card):
• The internal connections to the TMC board must be properly set
for 1-3 three-wire independent elements (socket X3 on the TMC),
or
1-6 sensor elements with common return (socket X2 on the TMC).
• The TMC board must be adapted to the type of sensor that is
used. For average elements or sensor elements with common
return wire there must be three jumpers in socket X4 and one
jumper in socket X5.
For three-wire independent elements no jumpers shall be
installed.
Normally these jumpers are installed at factory, and do not need to
be changed unless you change to other sensor types than origi-
nally specified.
Use the TankMaster WinSetup program to configure the temperature
sensors. WinSetup allows you to configure the transmitter by specifying
sensor type, sensor positions and measurement range.
Connecting the Temperature Sensors
Temperature sensors must be connected in the correct order starting
with connection X12:8 for temperature sensor one. The other sensors
are connected as shown in Tables 11-8 and 11-9.
Spot Elements
Spot temperature sensors use two wires per sensor plus one wire for
common return current.
