Priming the Hoses
NOTE:
To prime the hoses without the outlet pressure sensor installed, the high pressure and low pressure
setpoints must be set to maximum (500 psi) value. A priming recipe can be saved to simplify priming
setup.
1.
Set the Shot Size as required.
See adjusting the Shot Size
.
2.
Do the Material Pump Servo Start Up Sequence
(If Required)
.
3.
From the SHOT/FLOW screen. Under PUMP MODE press the SHOT button.
4.
At the pump outlets, close the ratio check ball valves.
5.
Remove the dispense valve from its mount if necessary.
6.
Hold the material hose and dispense valve outlet at a constant incline from the pumps so that air
can be pushed out by the material when the machine is cycled. Avoid sags in the hoses!
7.
Position a waste container under the outlet to catch dispensed material. Select the start device.
8.
While keeping the hoses at a constant incline, cycle the machine slowly until all signs of air have
disappeared. Then release the start device.
To avoid material spitting, keep flow rate low.
9.
Once air-free material is flowing from the outlet, press the RETRACT button.
10.
Remount the dispense valve before proceeding.
11.
Load recipe to run application before starting production.
Priming the Hoses ensures that air-free material is flowing through the material hoses and out
the dispense valve outlet. Before proceeding, load the machine with materials.
Priming is critical to keep the PosiRatio working properly.
