The controller will mark failed stations in the logs, and continue irrigating with stations that pass the individual flow tests. -

Conditional Response Conditional Response Conditional Responses allow a sensor or condition to trigger something to happen. This can be as simple as telling a station to start when a sensor is opened, to much more complex operations such as switching water supplies to a Flow Zone based on a sensor position. -

Page 51: Switch P/Mvs
Conditional Response SWITCH P/MVS To enable P/MV switching on sensor input, each station in the affected Flow Zone should be set to call for both P/MV outputs. When the sensor is alarmed, or changes position, it should then be set to “Close P/MV” for the P/MV that is not wanted. In this way, only one P/MV would be active at any given moment, because the stations are calling for both of them, but one is disabled by the sensor input. -
