3.
If the motor exceeds the desired RPM, decrease the high offset by 10 and hold INC again.
4.
Repeat step 3 until the motor runs at the desired RPM.
5.
Add 10 to the current high offset value and use the Edit mode to program the new high offset value.
PWM Low Offset
The PWM low offset is used to set the minimum desired RPM or hydraulic output (zero point or shutoff point) of
a PWM (Pulse Width Modulated) control valve.
To calibrate the low offset value:
1.
Toggle the console to manual (MAN) mode and toggle any boom and master switches to the on position.
2.
Hold the INC/DEC switch in the decrease position until motor stops.
3.
Use the Edit mode to increase the low offset value until motor runs.
4.
Subtract 10 from the current low offset value and use the Edit mode to program the new low offset value.
5.
Verify the correct low offset value by holding the INC/DEC switch in the decrease position. If motor does not
stop, reduce the offset value by 10 and repeat.
PWM Frequency
Used to set the coil frequency of PWM valve (default is 122 Hz). Refer to the PWM control valve manufacturer
specifications for recommended PWM frequency.
Preset PWM Offset (PWM Valves Only)
When valve selection is programmed in PWM-Close mode, this can be set to provide an initial pulse width to
the valve upon turning on booms or product. When programmed to zero, pulse width will return to previous
state. When non-zero, initial pulse width can be selected between 1 (slow) and 255 (full scale). When
programmed in PWM valve mode, PWM output will not exceed this value if non-zero when booms are off.
Standby Pressure (PWM Valves Only)
Note:
The standby pressure enable feature must be enabled to display the standby pressure value on
the SCS console. Refer to the Standby (Pressure) Enable (PWM Valves Only) section on page 43
for details.
Enter a non-zero value to set the target pressure for a liquid product system when in a standby condition in
automatic control mode. When all of the boom valves or the master switch is in the off position, the system will
maintain the target standby pressure in the product lines to keep the system charged and minimize the time
required to re-establish a spray pattern when application is resumed. The standby pressure value is entered in
PSI [kPa or BAR].
Note:
This feature is disabled when controlling product rate in manual control mode.
Rate Bump Delta
Sets the increment at which rate cal is increased or decreased using INC/DEC switch while in automatic
(AUTO) control mode.
