FREQUENCY DISPLAY
The TEST key can also be used to display the running frequency. When the
press head is in the UP position, press and hold the TEST key for 3 seconds.
The information on the display will change from the power display (watts) to
a frequency counter display (Hz). After this switch, the power is captured (no
longer updated) and the frequency display will update every second. This
information can help diagnose problems with the horn and/or stack
assembly.
OVERLOAD PROTECTION
The overload protection circuit will terminate ultrasonics 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, a
repetitive beep will sound and the O. L. 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, refer to the actuator instruction manual which
may recommend one of the following possible solutions:
— 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)
