cursor should show up under one digit), scroll Up/Down on the keypad to
adjust valve output to the Min or Max speed, and ENTER to save settings.

For Wt/Area (g/m*m) operation a feedback sensor is required. Select -
>PROGRAM MODE->SENSORS & VALVES->SPINNER SETUP->AUTO NULL, Press
ENTER to select, and ENTER again to start. Once AUTO NULL stops it
completes. Also a width calibration is required. From the SPINNER SETUP menu
select WIDTH CALIBRATION. On the screen you need to put in the spreading
width at 0 rpm (typically the diameter of the spinner), and then select
CONVEYOR knob to start the conveyor. Gradually increase the spinner setting to
the maximum spreading width required, measure the width, turn all knobs to
off, key in measured spreading width in mm, and then select ACCEPT VALUE.

For MANUAL operation, select MANUAL MODE on SYSTEM SETUP->PREWET
MODE menu screen, then select Min Out or Max Out, press ENTER to go into
edit mode (an cursor should show up under one digit), Press Up/Down on the
keypad to control the flow of the pump to the desired Min or Max flow rates,
press ENTER to store the value and exit edit mode.
•
For CLOSED LOOP operation, either pulses/rev or flow/min, ->PROGRAM
MODE->SENSORS & VALVES->CONVEYOR SETUP->VALVE SETTINGS, ensure
that correct pulses are put in, Select AUTO NULL, Press ENTER to select, and
ENTER again to start. Once AUTO NULL stops it completes.
Note: For very slow conveyors (max RPM < 100) the AUTO NULL may start twice to
calculate correct max RPM value.

The max RPM for a typical conveyor motor is over 250, and the CS-440RC
controllers set parameter ranges to accommodate that. In cases of max conveyor
RPM less than 250 the CS-440RC controllers would detect the low conveyor RPM on
the first null attempt to adjust RPM range, and then determine the Min and Max the
second time.

“Forward Gain” is designed to help conveyor overcome the inherited hydraulic
motor pulsing problem by boosting the conveyor valve output when vehicle starts to
move. Once the hydraulic motor inlet oil pressure is sufficient to create motion, the
motor will pulse during start up until it receives enough oil flow for continuous
motion. Forward Gain is only temporary and it will disappear once the conveyor is
turning. The feature is very helpful to eliminate conveyor pulsing at start up.
