Data Menu
Low Flow Limit
If actual volume/minute falls below the assigned limit, the control valve will be controlled to low flow limit and
low limit alarm is activated. This value is automatically proportioned to the percentage of booms that are on
(i.e. if the entered low limit is 4 and half the total boom length is shut off, the console automatically reduces the
low limit to 2). Low limit value is entered in GPM [L/min] or PPM [kg/min].
Low Tank
When level in tank falls below the volume/tank value, the low level alarm is activated. The alarm will deactivate
when the booms are turned OFF or a value equal to or greater than the low tank value is entered as the
VOLUME/TANK. Entering “0” in low tank disables the alarm.
Valve Delay
This value is the delay between when the SCS console will control flow rate after the booms have been turned
on. This setting can be set between 0-9 seconds.
This delay is active if the time between turning OFF and turning ON the booms is less than 30 seconds.
Spreader Constant
The spreader constant should be set at zero when applying liquid products.
See the Spreader Constant section on page 58 for details on calculating the spreader constant. The spreader
constant may be entered during initial console programming or through the Data Menu.

Valve Cal 2
This value can fine tune control valve response and help control application rate oscillations when the console
is programmed in PWM mode.
When a fast close valve is selected, valve cal 2 is utilized to enable a high resolution rate control for lower
application rates. Enter a non-zero value for the time, in milliseconds, which a closed valve will be driven open
before switching into high resolution control. For example, a value of 200 will give the valve a 200 millisecond
“burst” at a full 12 volts to open the fast valve from the closed position before resuming product rate control. A
zero value will disable this feature.
Note:
If the dual loop control feature is enabled, the valve cal 2 value will be replaced with system gain.
Refer to the Dual Loop Control (PWM Valves Only) section on page 43 for information on the dual
loop control feature or the Dual Loop Control Mode Settings section on page 57 for information on
configuring or adjusting the dual loop control settings.
Pump Cal/Fan Cal
Set the number of pulses per revolution of the pump or fan for pump/fan RPM readout.
