Purge the System
With the gas supply turned off, operate the melter and ProMeter VDK
dispensing module as normal to dispense a minimum of one tank volume of
adhesive.
1. Ensure that the dispensing modules are properly positioned for purging,
or place a container under the nozzles to catch the material.
2. Verify that the adhesive supply pressure is correct.
3. Access the Drive Setup screen (see Figure 23 on page 48) and press the
Push to Purge button. Observe the dispensing modules to ensure
adhesive flows from the modules.
NOTE: Depending on the material type and how it is being processed,
the system may need to be purged for several minutes.
Adjust Foam Density
The FoamMix Flex foaming system is capable of significantly reducing
silicone density. Foam density is a function of the type of silicone, nitrogen
gas pressure, and barometric pressure. The speed of the FoamMix Flex
foaming system motor is not adjustable and therefore has no effect on
changing the density of the foamed silicone. To create silicone foam, the
pressure of the gas introduced into the FoamMix Flex foaming system must
be a minimum of 150 psi greater than the inlet pressure. Inlet pressure is
indicated on the display of the controller PLC.
NOTE: Although the Nordson–supplied nitrogen pressure regulator has two
adjustment knobs, the smaller of the two knobs is factory set and locked.
DO NOT adjust this knob or foam quality will be adversely affected.
