Advanced Settings and Features
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, to apply 12.0 oz.
[0.35 L] of product with every gallon of carrier product, enter 12.0 [0.35] in this field. This function works in
manual rate control mode only.
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.
Dual Pressure Area
Pressures monitored by the Viper Pro, via electronic pressure transducers, are displayed as P1 (Pressure
Transducer 1) and P2 (Pressure Transducer 2) on the Viper Pro.
Viper Pro displays:
• All dashes if the node does not detect a pressure transducer.
• CAL if it detects a pressure transducer but the transducer is not calibrated.
Note:
Pressure readings are provided as display only and do not affect product control. Refer to the
Pressure Transducer section on page 245 for details on calibrating any pressure transducers
connected to the CAN control system.
