Graco VRM Instructions Manual page 51

System #1
This screen allows the user to set mechanical system
settings and the Dispense Mode setting.
Dispense mode can be set to time, volume, or weight.
Dispense mode controls how dispense quantities are
measured. If Weight mode is selected weight dispensing
must be calibrated, see Calibration on page 29 for
more information.
Pump sizes and inlet pressures must be entered on this
screen. The inlet pressure is the minimum allowable
fluid inlet pressure. If the inlet pressure is below this
value, dispensing is disabled. If pump sizes and inlet
pressures are not entered properly, system performance
will be affected.
NOTE: It is recommended that users wishing to enter
setpoints or view feedback in weight units use the
machine in "weight flow". To use weight flow, set the Dis-
pense mode to Time and set the Flow units to weight.
See Advanced #2 screen for flow units, page 54.

System #2
This screen allows the user to set the Gel Timer proper-
ties and set which items are installed on the machine.
NOTICE
The correct dispense valve option must be selected.
Selecting an incorrect dispense valve option will
lead to erratic machine performance.
When enabling the Gel Timer, the user must select one
of the 100 available shot definitions to use as the Gel
Shot. This shot will be dispensed when the Idle Period
expires. The Idle Period will begin after a dispense is
completed. Any dispense operation in the middle of the
timer countdown will reset the Idle Period counter. The
system will generate an audible alarm that will begin the
user-entered number of seconds before the Idle Period
expires.
The hydraulic level sensor and hydraulic RTD for the
pump line must be enabled when installed in the sys-
tem. If the sensors are not marked as enabled, they will
be ignored.
