11. APPLIED FUNCTION (continued)
1) dAIHEn Display
If “dAI” and “HEn” in the displays blink, it indicates the “Torch switch off state waiting“.
When turning on the power switch, the displays on the front panel shows “dAI” and “Hen” for one
second, then the welding power source becomes operable. But, if the torch switch remains on,
the safety circuit will function, the welding power source will hold a halt condition, then the
WARNING lamp and "dAI” and “HEn" shown in the displays will blink. In this case, turn off the
torch switch to reset the safety circuit and make the welding power source operable.
2) E-000 Display
If “ E-“ and “000” in the displays blink, it indicates the “Operation Stop “.
When disconnecting the wiring of the STOP terminals (Operation Stop terminals: wiring number
143) on the 12P external connection terminal block, “E-“ and “000” in the displays blink and the
welding power source stops. In this case, after turning off the power switch and eliminating the
possible causes of the stoppage of the welding power source, short-circuit the STOP terminals
and turn on the power switch to cancel the error.
NOTE: When canceling Operation Stop, it is also possible to solve the error only by short-
circuiting the Operation Stop terminals again without start the welding power source up
again. Refer to Section 10.2.1 (4), “Selecting Auto/Semi-auto”.
3) E-100 Display
If “E-“ and “ 100” the displays blink in, it indicates the " Control power supply error ".
If there is an error in the control power source, the warning lamp will light up and “E-“ and “100” in
the displays will blink, then the welding power source will automatically stop. To cancel the error,
start the machine up again.
4) E-200 Display
If “E-“ and “200” in the displays blink, it indicates the " Primary/Secondary current detection error ".
If an error is detected in the current detecting area, “E-“ and “200” in the displays will blink and the
welding power source will stop automatically. In this case, turn off the power switch, then turn it on
again after making sure that CN8 and CN9 on the printed circuit board P10264U are surely
connected.
5) E-210 Display
If “E-“ and “210” in the displays blink, it indicates the " Error in the voltage detection wire ".
If there is an error in the plus voltage detection line (+), the warning lamp will light up, “E-“ and
“210” in the displays will blink, then the welding power source will stop automatically. In this case,
after checking to make sure that the wire feeder control cable (10P) is not damaged and that CN6
and CN10 on the printed circuit board P10264T, CN23 and CN 24 on the printed circuit board
P10264U, and CN 1 on the printed circuit board P10264X are surely connected, start the machine
up again.
6) E-300 Display
If “E-“ and “300” in the displays blink, it indicates the "Thermal overload"
If the actual duty cycle exceeds the rated duty cycle of or temperature inside the welding power
source increases, "E-“ and “300" will blink and the welding power source will stop automatically.
At this time, the temperature lamp also will be lit. In this case, wait more than 10 minutes with the
power switch pressed and the fan turned. When restart welding, turn off the power switch and
restore the system after lowering the duty cycle and the welding current. Such action will cancel
the error. Repetitious welding without more than ten-minute rest may lead to damage to the
welding machine. Refer to Section 3.1, “Rated Duty Cycle” for the rated duty cycle of the welding
power source.
