ONNECTIONS
Transmitter and receiver connections are made at terminal positions 23 through 34. Insert and secure
the appropriate color conductor in the numbered position. Positions 26, 27, and 28 accept identically
colored conductors from both the transmitter and receiver. For ease of installation, the terminal block
can be removed from the controller. See the table below for a color code/terminal number cross-
reference.
