(No Setpoint Switch).
9. Feed the extra cable back through the hole in
the rubber insulator.
10. Snap the sensor front to the sensor base plate
by first hooking the sensor front to the bottom
latches, and then pushing the top of the sensor
front into place until it latches.
11. Tighten the sensor front retaining screw. See
Figure 2.
12. Terminate the other end of the wires either (a) at
the MBC/RBC module terminal block(s
)
(
Figure 5) or (b) at the appropriate UC terminal
blocks (Figure 6.)
The installation is now complete.
Terminating the Cable Wires
NOTE:
1. All connections for one sensor must be
terminated in the same cabinet, whether
MBC, RBC, MEC or UC.
2. Unitary Controller installations: On the
UC Input/Output Card, place the
universal inputs jumper in the RTD
position.
