1.5 Temperature Interconnection
(for primary-primary setups)
When the display uses the quick-connect
interconnect cable, this connection is already
complete.
When the interconnect cable is not used, a 4-
conductor shielded cable is needed to terminate
the temperature sensor from display one to
display two.
One end terminates at the 4-position terminal
block (TB4) on the primary display. The other
end terminates at the 4-position terminal block
(TB4) in the second display. Refer to Figure 7
and the following table for correct interconnect
locations.
Note: Do not connect the wire to pin one on
either display.

1.6 Sensor Replacement
If the temperature sensor board or wiring
malfunctions, access it by:
1. Open the temperature sensor housing by
removing the four nuts from the bottom and
then removing the five bottom disks. Refer to
Figure 8 for details on sensor housing
disassembly.
2. Label the wires connected to the temperature
sensor board and then disconnect the cable
from the sensor terminal block in the
temperature sensor housing.
