Batch Calibration Procedure
NOTE: This procedure applies to systems using the
Graco Motor Control. If you are using a VFD, follow
the instructions in that user manual.
1. The system is in Batch Control Mode. Menu
G200 = 1.
2. The pump is primed. See
Start and Adjust the Pump, page 28
.
3. Set the desired batch flow rate on the Batch
Mode Target Flow menu G247.
4. Set the desired batch volume (V
batch
) on the Run
Mode screen. Note that a large volume is more
accurate, at least 10 or more cycles. See Set
Flow Units (menu G201) to change units.
5. With a container ready to catch the dispensed
material, start the pump.
6. The pump will run for the set batch volume.
7. After the pump has stopped, measure the volume
(V
actual
) that was actually captured during the
dispense. Be sure to measure in the same units
as the batch setpoint.
8. See Set the Pump K-Factor (menu G203).
Write down the K-factor currently displayed
(K-Factor
old
).
9. Calculate the new K-Factor using the following
formula:
K-Factor
new
= K-Factor
old
✕
(V
actual
/
V
batch
)
10. Set the G203 menu to K-Factor
new
.
Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure
is relieved manually. To help prevent serious
injury from pressurized fluid, such as splashing
in the eyes or on skin, follow the Pressure Relief
Procedure when you stop pumping and before you
clean, check, or service the equipment.
NOTE: For split manifold units, perform pressure
relief procedure for both sides of the pump.
1. Remove power from the system.
2. Open the dispensing valve, if used.
3. Open the fluid drain valve (L) to relieve fluid
pressure. Have a container ready to catch the
drainage.
4. Close the pump air valve.
5. Units with a compressor: Cycle the valve to
bleed any remaining air.
Pump Shutdown
At the end of the work shift and before you check,
adjust, clean, or repair the system, follow the
Pressure Relief Procedure, page 29
