Speed Control: Controls the rotation speed ofthe tumble barrel.Optional Media Blow-off: A blow-off timer is situatedinside the variable speed panel, but it does not operateany controls unless the blow-off option was requestedwhen the cabinet was ordered. If the cabinet includesthe option, blow-off automatically begins at the end ofthe blast cycle. Adjust the timer to the length of time theblow-off is to remain ON. Blow-off automatically stops atthe end of the timed cycle. If media remains in the barrelor on the parts after the cycle, increase blow-off time.NOTE: If the blow-off option was not requested, setthe timer to 0 and leave it there. Because the timer isincluded and wired into the circuit, the blow off optionmay be added later. Refer to the wiring schematicstowed inside the panel.48351269 7 |
