4. Pull the field wiring to the LB wiring housing
mounted on the sensor.
5. Connect the field wiring to the transmitter with the
positive (+) 26V supply lead to the PWR wire and
negative signal lead to the SIG wire.
See Figure 4 and Table 1.
For 544-562-XX variants, connect the field wiring to
the transmitter with the positive (+) 26V supply lead
to terminal No. 1 and the negative signal lead to
terminal No. 2.
NOTE: In applications where condensate may
accumulate (chillers, low temperature
sensing, and so on) seal all wire connections
with RTV sealant.
