Control Valve Delay and Valve Advance
The Control Valve Delay feature allows the user to set a delay between the time the booms are turned on and
when the console begins to control the flow rate. The delay is active if the time between turning off the booms
and turning them back on is less than 30 seconds.
The Valve Advance feature allows the user to set the amount of time (in seconds) the valve is open.
Press the SPEED CAL button until the console displays the message “CONTROL VALVE DELAY” and four
digits (
X X X X ). The first digit is the Control Valve Delay value. The value (1 - 9) represents the number of
seconds of delay in turning on automatic control. A value of 0 means that there is no delay. The third digit is
the Valve Advance value. The value (1 - 9) represents the number of seconds in which the valve will be opened
upon all boom sections being turned OFF in automatic control. A value of 0 means that there is no advance.
Note:
A beginning value of 1020 is recommended for low rate situations to build up pressure when
turning the master switch on. For best results, approach the headlands at consistent speeds while
turning all boom sections off.
Zero Speed Shut-Off
The Zero Speed Shut-Off function is active when C-FC (fast-close valve) or C-PC (PWM close valve) is
selected, and cannot be disabled. The valve will receive a decrease signal and run closed when the speed
drops to 0.7 mph or less. The only way the console can operate under this speed is in the manual mode.
When the Zero Speed Shut-Off has occurred, the master switch must be turned off and back on to restart the
system. If a constant speed greater than 0.7 mph is not reached within 10 seconds, the Zero Speed Shut-Off
will occur again.

within 15 seconds.
