10.3.11 E011 Unit Too Hot-Please Wait
Fatal, meaning you have to power down to continue welding
No
Acknowledge, meaning the error will exist as long as the unit is powered on.
(Note, welding can continue while the error exists)
No
Description:
When the internal temperature sensor trips, the control board disables welding so as
not to allow damage to the unit. This error is displayed while the unit is in the
overtemperature condition and disappears when it is ready for more welding. The
normally closed temperature sensor is located on the output board and connects to
pins 1 and 6 of JP3 on the control board. The sensor closes when it reaches 80 deg
C.
Likely problems or items to check - in order from most likely to least likely:
Fan is not functional or is blocked. Check that fan can physically turn and the wiring
to the fan. Short the fan sensor to manually activate the fan. Make sure it works.
1. Inspect wiring from overtemp thermostat to the control board (JP1 on control
board pins 1 and 6). Measure ~22VDC while open, near 0VDC while closed.
2. Scroll on user interface using time up\down arrows for other errors that may
indicate another problem. Measure 24VDC sup- ply on control (JP11 pins 7 and
17).
3. Replace sensor
4. Replace wiring
