(1) LTB and LTB1 refer to low-voltage terminal boards with numbers 1–20 and two test terminals. (2) Connect an optional remote sensor (p/n BAYSENS017) to terminals S1 and S2. Connect the shield wire (drain wire) from the shielded cable to terminal 11. (3) Connect the 24 Vac power supply from the unit controller to terminals 11 and 14. (IntelliPak power supply voltage is 12–15 Vac.) (4) Use terminal 15 on older 3–25 ton Voyager units with low-voltage terminal boards numbered 1–18 with two test terminals. (5) Data communication between the unit controller and the sensor is accomplished by a serial link connected at terminal 12. | |||||||||||
