FR-20 & FR-30 Feeder Installation/Maintenance
If you are supplying your own prefeeder, you are responsible for:
▲
Providing and installing the feeder's bowl level switch so it can
control the product flow of your prefeeder.
▲
Setting the timing delay for the feeder's bowl level switch.
▲
Correctly positioning the prefeeder. Generally, the prefeeder
must discharge product to fall on the lowest side of the feeder's
disc, halfway between its center and its outside diameter. Take a
handful of product and drop them from the snout of your prefeeder
into the feeder bowl. Avoid product bouncing up off the disc onto
the rim of the feeder bowl, this could disturb properly oriented
product. Reposition the prefeeder (as often as necessary) until
product lands correctly.
Step 5ÑConnect Power and Air.
Connect your feeder to main
power and compressed air (if applicable). Don't change the feeder’s
main air regulator; it should already be correct when you receive
the feeder.
Starting the Feeder for the First Time
Step 1ÑSecure Safety Covers and Clothes.
Before turning on
power and air, make sure safety covers are in place and that you are
dressed appropriately for safety.
Step 2ÑTurn on Power and Air.
Turn on the feeder’s power. If
applicable, turn on the feeder’s main air regulator.
Step 3ÑCheck for Rubbing Parts.
Run the prefeeder, feeder and
output device without product. In the unlikely event that you hear
squeaks and squeals (there should be none), shut down immediately
and check for any remaining packing, such as between the backup
ring and the rim of the bowl.
