Wiring The Flow-Sync To The Irrigation System

Topics: 
Installation Procedures

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.

Wiring the Sensor

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

  • In the ACC controller, the terminals are marked “Flow”, one for red and one for black.
  • In the I-Core controller, the terminals are marked either S1 (one is red, and one is black) or S2 (or S3 in metal versions).
  • When used with a Hunter ICD-SEN sensor decoder, consult the manual for the ICD-SEN.
  • Flow-Sync may only be used on Port A of a sensor decoder.
  • Cut the purple loop (Port A) on the sensor decoder.
  • Observe polarity-when the loop is cut, the lead on the station label side of the ICD-SEN is the negative (-) side.
  • Connect the black wire from Flow-Sync to the negative side of the decoder port, and connect the red wire to the positive side of the port.
  • Finish configuration as described in the ICD-SEN and ACC controller documentation.

WIRING THE FLOW-SYNC TO THE IRRIGATION SYSTEM

 

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.
