OVERLOAD PROTECTION

The overload protection circuit will terminate sonics when the system is

operated under adverse conditions, i.e., improper tuning, excessive power

supply loading, loose or failed horn or booster, thereby protecting the power

supply and other system components. When an overload condition exists, the

RESET

button will illuminate and remain lit until the button is pressed

(regardless of whether the condition is corrected or not). If a repeated

overload condition exists, resolve the problem before a failure of the power

supply occurs.

If an overload condition exists, try the following:

— decrease horn force

— decrease amplitude (change booster or decrease output control)

— decrease downspeed

— check for loose or broken studs

— check the coupling surfaces between horn/booster and booster/converter

— check for cracked horn or booster

— check to see if the load meter exceeds 100% during weld process (if so, a

higher powered unit is needed)

If you cannot remedy the situation, contact Sonics’ Service Department at

1-800-745-1105.

NOTE: System will still

cycle even though the

power supply is in

overload condition, but

sonics will not be

delivered.
