Setup #2 Screen

Overview
The Dispense Mode, Flow Rate, and Dispense Duration
settings apply to Automatic Control Mode

screen independent of changes made on the Mainte-
nance screen.
The Bead Scale value is a duplicate to the Bead Scale
setting on the Home Screen, which can be enabled or
disabled from the Setup #1 screen. See Setup #1
Screen on page 88 for more information.

Pre-Charge
This is the pressure between the meter and the dis-
pense valve when the dispense valve is closed. If the
pre-charge setting is non-zero then, immediately after
dispensing, the gear meter will continue to rotate after
the dispense valve closes until the pre-charge pressure
value is achieved. The maximum Pre-Charge value is
2500 psi (17.2 MPa, 172 bar).
Larger values for the On Delay setting lead to larger
pressures in the system. If a value too large is input,
the machine could over-pressurize leading to rup-
tured components and serious injury.
