System Screen 1
This screen allows the user to set important system set-
tings. Control Mode can be set to Flow. With Control
Mode set to Flow, the machine will dispense at a con-
tinuous flow rate regardless of pressure fluctuations
unless pressure alarm conditions occur.
Dispense Mode can be set to Time, Volume, and
Weight. Dispense Mode controls how displayed
amounts are measured. See Calibrate HFR on page 37
for more information.
Pump sizes and inlet pressures must be entered on this
screen.
NOTICE
If pump sizes and inlet pressures are not entered
properly, system performance will be affected.
The inlet pressure must be set to the maximum feed
pressure that will be seen by that side of the machine.
The maximum working pressure for the machine is dis-
played on this screen. The maximum working pressure
is dependent on the installed hoses and dispense valve.
The maximum working pressure is set to the lowest
rated system component. If 2000 psi hoses are
installed and the maximum working pressure displayed
is not 2000 psi, see manual 313998 for instructions to
set the maximum working pressure for hoses. If the
installed dispense valve rating is below the maximum
working pressure shown here, verify the correct dis-
pense valve is selected on System Screen 2.

Appendix B - ADM Setup Screens Overview
System Screen 2
This screen allows the user to set which items are
installed on the machine.
The hydraulic level sensor and hydraulic RTD for both
the pump line and mix head must be marked as
enabled when installed in the system. If the sensors are
not marked as enabled, they will be ignored by the
machine controls.
Select the dispense valve installed in the system. This
selection is critical to ensure proper operation of the
machine. When a mix head is selected,
become active when the
pressing this button will open a screen used to define
the mix head operating parameters. See the Mix Head
Operating Details Screen on page 60.
Post Dispense Shot Disable is a feature where the user
can disable shot requests for zero to five seconds after
the completion of a dispense. This feature is not appli-
cable for P2/Fusion Dispense Valves. This feature can
not be active if the Pre Dispense Delay feature is active.
Pre Dispense Delay is a feature where the HFR can
delay the start of a dispense until the user has pressed
and held the foot switch for the duration entered. For
example, if the user enters a five second duration, the
footswitch must be held on continuously for five sec-
onds before the HFR will start a dispense. This feature
is not available for recirculation systems or applicable
for P2/Fusion Dispense Valve applications. This feature
can not be active if the Post Dispense Shot Disable fea-
ture is active.
