To access the Flow Monitor menu, hold the - button and turn the dial to Pump, then release the - button.
You will have access to the following features:
- High Flow Shutdown Setup
- Low Flow Shutdown Setup
- Total Flow
- Delay
- Station Level Flow Learning (must have a base run time set for each station learning flow)
High-flow shutdown threshold can be set from 110 – 200% using the + and – buttons. This applies to each individual station. When this threshold is exceeded, the individual station will be shut down, an alarm will be posted on the display, and the remaining stations will continue running in the automatic program.
Low-flow shutdown threshold is accessed by pressing the right arrow button from the high-flow setup. This also applies to each station and can be set from 20 – 90% using the + and – buttons. When this threshold is exceeded, the individual station will be shut down, an alarm will be posted on the display, and the remaining stations will continue running in the automatic program.
The Total Overflow threshold is for catastrophic high-flow shutdown and can be set from 1 to 1,000 GPM or pm. This alarm applies to all stations and programs and shuts down all irrigation when the maximum threshold is exceeded.
- Press the right arrow button to access the Total Overflow setting.
This can be set from 1 to 1,000 seconds and is useful in preventing false flow alarms during station startup. The high- and low-flow alarm conditions have a preset 60-second delay to help with hydraulic fluctuations. You can use this additional Delay factor to ensure accurate flow condition. This helps ensure any abnormal flow rates detected are persistent throughout the Delay duration and aren’t due to pump or pressure ramp-up.
- Press the right arrow button to access the Delay setting.
The last step in the Flow Monitoring setup is for Station-Level Flow Learning. To access the nominal flows for each station in the system, press the right arrow button from the Delay menu. Cycle through all stations using the left and right arrow buttons to view or manually input all expected flow rates.
To enable the flow learning process, press the PRG button within the Flow Monitoring menu at any time. This will initiate a flow reading/calibration for each station, taking approximately 45-60 seconds per station. If there are individual stations that should be left out of the flow monitoring analysis, they can be set to OFF. You can also manually input or edit the nominal flows using the + and – buttons. To cancel the flow learning process, press the PRG button again to revert to the flow monitoring menus.
IMPORTANT: The station must have a programmed run time in the Set Station Run Times dial position prior to the learning flow.
