WARNING! Flow-Sync is only designed for low-voltage connection to approved irrigation controller flow terminals. do not install in high-voltage 110V or 230V circuits.
Flow-Sync has two wire leads for the controller connection. These may be extended up to 1000 ft/300 m from the controller with direct burial- rated 18 AWG (1 mm) wires. Flow-Sync may also be used with Hunter ICD-SEN sensor decoders.
The red and black lead wires from the Flow-Sync Sensor are for DC voltage. The red wire is positive (+) and the black wire is negative (-).
When extending the wires to reach the controller flow sensor connection, the red and black wire polarity must be observed. Use an extension wire that has a similar color code.
Connect the red lead from the sensor to the red (+) flow terminal in the controller. Connect the black lead from the sensor to the black (-) terminal in the controller. Use only quality waterproof connectors for all wire connections
Note: The Flow-Sync Sensor can be installed up to a maximum of 1,000 ft/300 m from the controller when installed with 18 AWG or 1 mm gauge or larger copper wire.
Proper irrigation system design and operation assures optimum performance of the Flow-Sync in monitoring for potential high flow conditions. Flow-Sync is primarily designed to shut off the irrigation system in the event of a catastrophic system failure such as a main line or lateral line break. However, depending upon the design of the irrigation system, the Flow-Sync can offer increased protection when components such as sprays or rotors are damaged or removed due to vandalism. The following may be helpful in making your Flow-Sync System operate at its optimum level.
