The CONTROL VALVE DELAY must be entered as a four digit value
advance features.
The first digit is the control valve delay value. The control valve delay feature sets the delay (in seconds) between when
the booms are turned ON and when the console begins to control the flow rate. Enter a value from 1 to 9 to set the
delay between 1 and 9 seconds respectively. Enter a value of 0 to disable this feature. The valve delay feature is
active if the time between turning the booms off and back on is less than 30 seconds.
The third digit is the valve advance value. This feature allows the operator to set the time (in seconds) which the control
valve will open after all boom sections are toggled off. Enter a value from 1 to 9 to set an advance time between 1
and 9 seconds respectively. The valve will then be more optimally positioned to pressurize the system when boom
sections are turned back on. Enter a value of 0 to disable the valve
The second and fourth values do not adjust the valve delay or advance feature and should be entered as zeros.
A starting value of 1020 is recommended to build up pressure during low rate applications in automatic control
mode with the master switch on. To disable the valve delay feature while utilizing the valve advance, enter a value
of 0020. The CONTROL VALVE DELAY value must be entered as a four digit number to ensure the system is
responding as expected.

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.
