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.
