Manual No. 016-3001-003 135
Advanced Settings and Features
PW Freq. Enter the coil frequency of the PWM valve in this field. When operating with hydraulic drive systems,
the default value is 60 Hz.
Note:
PW Freq is not used with ground drive carts.
Valve Delay. Set the valve delay to include a time delay between when the booms are turned on and when the
product nodes start to control the flow rate. Viper Pro activates this delay if the time between turning the boom
on and off is less than 30 seconds.
Note:
A value of zero must be entered if a Fast Close or PWM Close valve is used as the control valve or
when the Valve Type is programmed as a standard valve with an injection system.
Product Control Settings Area for Products 4-5
The Product Control Settings area displays an overview of the following calibration settings and values used
by the control system to monitor or adjust the rate of product application:
Note:
The following sections offer descriptions of the various options and settings used with products 4
and 5. For descriptions of the settings used with products 1 through 3, see the Product Control
Settings Area for Products 1-3 section on page 132.
The following data displays are shown in the Product Control Settings area for reference and monitoring
purposes only:
Area/Hour. Displays the current area per hour covered during product application. This value is calculated
using the programmed section set up and the vehicle speed.
Vol/Min. Displays the current volume per minute monitored by the selected product node or control channel
during active application. This value is calculated using the flow of product monitored by the flow meter.
PWM. Displays the current duty cycle of the PWM valve controlling product application (if applicable).
