Graco HFR Setup page 67

• Micro Motion Enabled: If checked (default is NOT
checked), the HFR will be capable of producing low
flows down to 0.16 cycles/minute, from the default
low rate of 3 cycles/minute.
NOTE: If the HFR is in pressure mode, the selection
is not relevant.
If the resultant low flow selection produces HFR
motor speeds less than 100 RPM or results in
motor stator currents less than 1.0 Amps RMS, the
selected flow may become unstable (as displayed
on the Diagnostic Run Screen to the left of the
home run screen, during a dispense). If this situa-
tion is present, more material restriction or a higher
flow selection may be required. The motor speed
can be monitored on the Diagnostic Run screen,
which must be enabled or turned ON by checking
the "Enable Diagnostic Screen" option on the
Advanced #4 setup screen.
• 2x Trigger For Dispense: When this box is
checked, the machine will require a double trigger
pull to initiate dispensing in shot or sequence
mode.
• Dispense from Home Position: When this box is
checked, the machine will be required to reach a
defined home position before dispensing in shot or
sequence mode.
• Disable Setpoint Not Reached Error: Checking or
enabling this option will turn off the generation of
Set point Not Reached deviations, which may
occur if the flow rate entered for the machine is a
low value.

Appendix B - ADM Setup Screens Overview
• Enable Diagnostic Screen: Check this box to
enable the optional ADM screens, enabling USB log
downloading, and erasing USB logs. For more
information about USB operation, see Appendix F
- USB Operation on page 91. For more information
about the optional screens, see Diagnostic screen
on page 75.
• Low Material Disables Dispense: When this box
is checked, the current dispense will terminate and
prevent additional dispenses when the supply sys-
tem indicates a low level.
• Limit Rate on Stall to Pressure: Check this box to
enable Limit Rate on Stall to Pressure. This will
slow the rate of pressure rise on a stall to pressure
system.
• Enable Range Calibration: Check this box to
enable Range Calibration. This creates a range of
shot offsets in a table based on the size of the shot.
The user must calibrate each range at the specified
flow rate. If the flow rate is changed, the table must
be recalibrated.
• Enable PrePoly Refresh: Check this box to enable
Prepoly Refresh. A Prepoly refresh will initiate a
cold start, heat the system to a specified tempera-
ture (Conditioning Screen 3), empty the prepoly
tank to the low level sensor and refill the tank.
When enabled, either the user may initiate a refresh
manually or through a scheduled task.
• Night Mode, Disabled, or Standby Modes:
Automatic refills are disabled. If the material
level drops below the low level sensor, a low
level alarm is thrown.
• Shot, Operator or Sequence Modes: The sys-
tem will monitor the amount of automatic refills
requested after the last shot has been taken. If
the system sees two refills without dispensing,
the system will generate a leak detection warn-
ing and disable the system. The system must
be completely powered down to clear the error.
• Enable Leak Detection: Check this box to enable
Leak Detection. Leak detection is intended for cata-
strophic leaks only. It requires a Graco auto fill con-
trol to be enabled and working. Leak detection is
not active during dispense.
