Pre Set PW
Use the Pre Set PW setting to set an initial target pulse width value when using a valve that is programmed in
PWM Close mode. Enter a value between 1 (slow pulsed width) to 255 (full-scale pulsed width). Viper uses this
value to send an initial pulse width to the valve when the sections or nodes are turned on. When a value is
entered in this field, the PWM output will not exceed this value when any non-zero sections are off.
When the Pre Set PW value is set to zero, the initial pulse width will be equal to the previous state.
PW Freq
Enter the coil frequency of the PWM valve in this field. The default value is 122 Hz.
Ratio Rate
Enter a Ratio Rate value when using a product in an injection system that uses a hand-held spray gun. The
product is injected as a ratio to the amount of carrier product applied. For example, if you want 12.0 ounces of
product applied with every gallon of carrier product, enter 12.0 in this field. This function works in manual mode
only.
Note:
This value must be set to zero (0) in a non-chemical injection application.
Valve Delay
Set the Valve Delay to include a time delay between when the sections are turned on and when the product
nodes start to control the flow rate. Viper activates this delay if the time between turning the section 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.
