Troubleshooting Guide - Hunter Rain-Clik Product Information

INSTALLATION INSTRUCTIONS
Sensor Bypass
The Sensor Bypass setting allows the user to manu-
ally override the Flow-Clik™ sensor. This is helpful
during situations that require the system to operate at
higher than "learned" flow rates (i.e. system winteriza-
tion, running a hose bib, or operating multiple valves).
To bypass the Flow-Clik sensor, turn the interrupt
period dial to the Sensor Bypass/Calibrate position.

(continued)
If the sensor experiences an overflow condition, the
system status indicator will identify the overflow, but
the interface box will continue to allow the controller
to operate.
SOLUTIONS
A) Check that the Interface Box power leads (yellow wires) are attached to the
24 VAC terminals on the controller.
B) Verify that the power to the controller is on.
Normal operation during an overflow condition. The Flow-Clik has identified
overflow condition and is waiting the pre-set startup delay period before shutting
the system off.
Normal operation during an overflow condition.
A) The Flow-Clik has identified an overflow condition and is waiting the
predetermined amount of time set as the Interrupt Period before restarting the
irrigation cycle.
B) The Interrupt Period setting is in the Manual Restart position requiring the
Flow-Clik be reset before irrigation can resume. Press the Restart System button
to reactivate the Flow-Clik.
Check System Status Indicator light is on (if light is off, see above).
Check Flow-Clik sensor wires (red and black wires) are properly connected.
A) Normal operation.
B) System is not balanced. Too much variation between flow rates of the zones
may prevent the Flow-Clik from sensing an overflow condition on the lower
flow zone(s). Flow-Clik will only shut the system down if flows exceed highest
flow zone.
Wait for start up delay period to end.
Reset the Flow-Clik to the highest flow zone.
It is recommended that the Flow-Clik be set at the time of day that the irrigation
system will be run. Note: If too much pressure fluctuation occurs, it may be
necessary to add pressure regulation to the system.
Check Flow-Clik sensor wires (red and black wires) are properly connected.
Check the wiring connections from the controller to the Interface Box.
Confirm that system pressure is off. Remove cap and pull sensor out of the sensor
body and inspect for debris or damage to the impeller.
Manually cycle system to find cause of system overflow.
Press the Restart/Calibrate button to reset the system status indicator.
