Advanced Settings and Features
Vacuum/Bin Alarm. The vacuum/bin alarm must be disabled for nodes or channels configured for standard
(non-injection) liquid product application control.
Enable the vacuum alarm feature if an injection pump is controlled via a CAN product control or motor control
node. When activated, the vacuum alarm displays an alert if the injection pump cannot draw product from the
supply tank.
Enable the bin alarm for granular applications if an optional bin level sensor is installed. With this feature
enabled, the Viper Pro will display an alert when the sensor detects the product level in the bin falls below the
sensor level.
Note:
Contact a local Raven dealer for information on injection systems or bin level sensors.
Flow/Shaft Alarm. Enable the flow/shaft alarm to display an alert if the field computer does not detect a signal
from the pump shaft encoder or flow switch. This alarm may be used to help troubleshoot flow errors with a
CAN motor control node.
Decimal Shift. Enable the decimal shift feature to increase the system accuracy for low application rates. In
the standard mode, the Viper Pro displays values to one decimal place. With the Decimal Shift feature
enabled, values will be displayed to two decimal places.
Note:
Verify all calibration values after the Decimal Shift feature is either enabled or disabled. Change
settings as necessary.
Agitator. The Viper Pro may be used to enable or disable an agitator to continuously mix a chemical
suspension. Contact a local Raven dealer for required hardware.
Display Smoothing. Enable the display smoothing feature to allow the field computer to smooth the rate
displayed during product applications. With this feature enabled, the actual rate (R
A
) in the rates area will
display the target rate (R
T
) as long as the actual monitored application rate remains within ±10% of the target
rate. The actual rate shown on the main screen will display the actual monitored rate if the application system
does not reach the target rate dead band (±10%) within 10 seconds.
Disable the display smoothing feature to monitor the actual application rate at all times.
Note:
The display smoothing feature is only active for products in Automatic control mode.
Ratio Rate. The ratio rate feature should only be enabled for chemical injection applications. Enabled the ratio
rate feature to allow an injected chemical to be applied in ratio to the amount of the carrier. See the Ratio Rate
section on page 139 to enter the ratio of injected chemical to carrier product.
