4. Insert the RTD sensor probe down through the top of the RTD Head
and holding the sensor probe from underneath the Head, turn the
probe screwing the spring into the threaded hole in the terminal
block. Stop when the top of the spring is flush with the top of the
terminal block. If the probe came with a terminal block, remove it,
since there should be a terminal block already mounted inside the
RTD Head.
5. Guide the sensor probe down through the bottom half of the union.
As the two halves of the union come together, you should feel some
resistance as the sensor probe contacts the bottom of the
thermowell. You should see the top of the probe rise (3/4" max.)
above the terminal block as you push the two halves of the union
together. If the assembly is to long or to short, you may need to
change-out the nipple for a different length.
6. Slide the union nut up and screw on to the top half of the union but
do not tighten.
7. Align the RTD Head such that the connecting conduit or cable will be
pointing in the desired direction and then tighten the union.
8. Install the probe wire spade lugs under the small screw heads per
drawing. One color (typically white) is one side of the RTD and will
go to the RTD (Out & +) connections on the 6200EX and the other
color (typically red) is the other side of the RTD and will go to (In & -).
See Figure 9 on page 12 for a view of the 6200EX RTD terminals.
