Do's and Don'ts

1. Use only LP-RP Receivers (Gray Molded Box) with the LogicPLUS Controllers (LP-42, LP-128 and Universal 2 PLUS). DO NOT use the L-RP (Black Molded Box) Receivers with the LogicPLUS Controllers or the LP-RP (Gray Box) Receiver with the Logic 1, Logic 2, Logic 3 or Universal-2 Controller.

2. Branching and Teeing is permitted. Plan well and take care to use only waterproof DBC-BR splice kits. All wire connections and splices are to be made in a valve box. DO NOT bury a connection or splice.

3. LogicPLUS receivers must be directly attached to the two-wire path: red wires to field wires, black wires to solenoid.

4. WIRE CONNECTIONS
a. All field wiring connections between the LogicPLUS Receiver Red Wires and field wires must use the enclosed DBC-BR splice kits provided with each LP-RP Receiver. There is one red wire for each field wire. DO NOT USE PRE- FILLED GEL TYPE WIRE NUTS.

b. All receiver to valve solenoid connections must be waterproof, using “dry type” wire connectors (HIT Products DBC series or 3MTM DBY/DBR seriesTM). They also may be
soldered and then installed in water- proof housings. DO NOT USE PRE-FILLED GEL
TYPE WIRE NUTS.

5. DO NOT install the LogicPLUS Controller, its receivers, or any LogicPLUS Field Wire within 15 feet of any high-voltage device; electrical panels, meters, pumps, equipment
or controls.

6. Use with standard 24 VAC solenoids only. DO NOT use any with low power/ diode bridge type solenoids.

7. Use different colored wires for each wire in each two-wire path.

8. LogicPLUS provides four separate field outputs. Line 1, Line 2, Line 3, and Line 4. DO NOT mix the wiring.

9. On multiple controller installations DO NOT connect any field wires of
one controller to those of another controller. Each controller must have a separate ground rod and power supply.

10. DO NOT “loop” field wiring. Terminate line at last valve for each wire run.

11. Install and ground a LP-SPD-F (Surge Protection Device for the Field wiring) every 300 to 500 feet in a valve box.
