monitors field speed, and operates the (rate) control
valve to deliver anhydrous ammonia at your desired rate.
Once setup for the applicator and preferences, and
configured for the rates/limits, the monitor is typically
used in the “RATE 1” or “RATE 2” FLOW CONTROL
modes.
POWER: must be ON
FLOW CONTROL: as desired
BOOMS: 1 or BOOMS 1,2&3 ON,
all others don’t-care (suggest OFF)
MASTER: OFF except when in field and in ground

POWER switch is ON (and power is supplied to the console).
If you turn the POWER switch off with the MASTER and any
BOOM switch on, the On/Off valve
remains OPEN, the
Control Valve may be open and ammonia may continue to
flow from the nurse tank to the knives or tines.
