Troubleshooting Tips for the ESP-ME3 Controller

If a High Flow condition is detected, a “High Flow Alarm” is shown at the display and the red alarm LED comes on. To clear the alarm press the “Hold to Start” right arrow button during the alarm message.

Initial Troubleshooting

1. Check the filter basket for debris
2. Confirm that the expected flow rates are above the minimum recommended flow rates for the FG100 (see table below):

Minimum Flow	Maximum Recommended Flow	Maximum Flow
3 GPM	25 GPM	35 GPM
11.35 LPM	94.63 LPM	132.49 LPM

See Operating Specifications for more information.

3. Ensure that the FG100 has been wired correctly.
4. Ensure there is flow in the system by running a manual irrigation program from the controller. Check to see if water is being emitted as expected.

Test the Controller

If the controller is not recognizing a flow input from this sensor, test the controller itself by disconnecting the flow sensor, and very quickly and repeatedly short together the flow +/- terminals or wires that connected the flow sensor to the controller. Do this about once a second for 30 seconds. The controller should recognize this shorting as flow. If it does not, the problem is in the controller, and not the flow sensor or the wiring to it.
