Unexpected NH3 Flow Detected

PC13152-19-17FEB11

This message will be displayed if the John Deere Rate Controller 2000 has attempted to close the On/Off valve but still detects flow. If the Control Valve OFF button is selected, the system will also attempt to shut off the control valve.

This message will only be displayed when using a dual valve system (i.e the control valve type is Standard or Fast).
