Pop-up Status Screens
System Status Signal Status Text Displayed System Status or Fault Explanation
Average Overload OVERLOAD - AVERAGE
AT X.XXX SECONDS
POWER ABOVE
GENERATOR RATING
An Average Overload fault tripped.
Output power exceeded rated wattage. Lower the welding
pressure or amplitude. Fault will reset when next weld
cycle starts.
Peak Overload OVERLOAD - PEAK
AT X.XXX SECONDS
CHECK STACK OR
COUPLING TO PART
A Peak Overload fault tripped.
Peak IGBT transistor current exceeded.
Caused by a severe frequency mis-match. Fault will reset
when next weld cycle starts.
End of Weld END OF WELD
SIGNAL
DETECTED
Automation activated End of Weld input.
This ends the weld, then hold time begins.
Status message is displayed a few seconds.
End of Cycle END OF CYCLE
SIGNAL
DETECTED
Automation activated the End of Cycle input.
This terminates the remaining weld cycle.
Status message is displayed a few seconds.
Over Temperature Fault SYSTEM OVER TEMP
DETECTED
System Over Temperature fault detected.
Check that cooling fan is operational. Check for dust
build-up in cooling channel.
Generator operation can continue after the system cools
down.
Overload Frequency OVERLOAD - FREQUENCY
AT X.XXX SECONDS
CHECK STACK AND CABLE
& RAMP UP TIME
Resonant frequency was not found.
Check for a defective stack component or for improper
stack assembly.
Check for a defective stack cable.
Fault will reset when next weld cycle starts.
Overload Frequency OVERLOAD - FREQUENCY
AT X.XXX SECONDS
CHECK FOR COUPLING
BETWEEN STACK AND
PART
Resonant frequency was lost during the cycle.
Check for a defective stack component or for improper
stack assembly.
Check for stack coupling to the xture.
Fault will reset when next weld cycle starts.
4-20 mA
Current Loop Fault
CURRENT LOOP FAULT
DETECTED
Remote control current loop fault detected.
Current loop current is less than 2mA.
Check current loop wiring and loop source.
This fault will set minimum amplitude level.
System Power Fault SYSTEM POWER FAULT
DETECTED
System AC line or power supply fault detected.
Check that AC line voltage level is normal.
Likely there will be no power for the front panel display.
Service may be required if this fault is displayed.
Front Panel Locked FRONT PANEL LOCKED
KEYPAD ENTRY NOT
ALLOWED
Front panel lockout input is activated.
Front panel changes are not allowed.
Warning pops-up if user attempts changes.
Status message is displayed a few seconds.
Empty Setup CURRENT SETUP
HAS NOT
BEEN PROGRAMMED
WELD CYCLE STOPPED
Warning text pops-up if a setup is empty.
User must program a valid welding setup.
