Description of Calibration Values

Drive Type Operation
Hydraulic The prewet set rate is set independently from the auger rate
by using a proportional valve on the valve block to control
pump speed. The system will be able to control the prewet
output in closed, open, and manual application modes.
Electric The prewet set rate is set independently from the auger rate
by using an electric motor to control the pump speed. The
system will be able to control the prewet output in closed,
open, and manual application modes.
Exhaust The prewet application is controlled entirely or partially
based on the auger rate by using the exhaust oil from the
auger and an optional proportional valve to control the pump
speed. When this drive type is selected it is recommended
to use the open or manual application modes to control
prewet.
Min DC
The Min DC menu item sets the duty cycle required to run the prewet pump at its slowest
rate. Min DC is used in closed, open, manual, and prewet prime modes, and should be
configured as accurately as possible. The default value is 20%. The Min DC menu item
will not be available if the Loop Mode menu item is set to Gravity Feed.
Use the green Standby knob to test the prewet pump output when adjusting the Min DC
value. If the loop mode is set to Closed and a prewet flowmeter is installed on the
system, the current prewet flowmeter frequency will also be shown on the screen to
assist with adjustments.
Max DC
The Max DC menu item sets the duty cycle required to run the prewet pump at its fastest
rate. Max DC is used in closed, open, manual, and prewet prime modes, and should be
configured as accurately as possible. The default value is 75%. The Max DC menu item
will not be available if the Loop Mode menu item is set to Gravity Feed.
Use the green Standby knob to test the prewet pump output when adjusting the Max DC
value. If the loop mode is set to Closed and a prewet flowmeter is installed on the
system, the current prewet flowmeter frequency will also be shown on the screen to
assist with adjustments.
Prewet Mat
The Prewet Mat menu allows you to configure settings for the prewet material. If Config →
Application Mode is set to Direct 1 Lane or Direct 3 Lane or if Config → Prewet is disabled, this
menu will be disabled.
Name
The Name menu item allows you to set a custom name for the prewet material, such as
“PWT” or “CACL”. A maximum of 5 characters can be used in the material name. This
name will appear on the Operation Screen when prewet is enabled. The default value is
PWT1.
AutoCal
The AutoCal menu item allows you to calibrate your displacement if your system is
closed loop and full speed displacement rate for the prewet liquid by measuring liquid
dispensed. For more information on how to use AutoCal, please see AutoCalibration of a
Prewet Liquid on page 37.
