11. APPLIED FUNCTION (continued)
7) E-510 Display
|
In the case of connecting the water pressure switch
|
If “E-“ and “510” in the displays blink, it indicates the “Abnormal water pressure”.
Then the welding machine will automatically stop. In this case, check to make sure that the water-
cooled hose does not leak water and that adequate cooling water is going through the hose.
When set the switch of the front panel “Water” and connected the relay contact of water pressure
between
J
and
K
on the 12P terminal block (TM12P), contact between
J
and
K
is “Open”
makes E-510 light up.
When using an air-cooled torch, make sure that the TORCH lamp on the front panel is OFF (AIR).
Refer to section 11.2.
8) E-600 Display
|
Refer to section 11.2
|
If "E-“ and “600" in the displays blink, it indicates the "Replacement of batteries (warning)".
This welding power source uses batteries so that it can hold the welding conditions in memory
even when no operation is carried out for long time. “E-“ and “600” in the displays blink when the
batteries get low. “E-“ and “600” are displayed only when the front panel and the welding power
source are temporarily not in use. To cancel the display of the error , press any key. Even when
“E-“ and “600” appear in the displays, welding can continued to be performed, but when the
batteries run down, the preset welding condition functions and the settings of functions
are all erased. The last welding conditions before power is applied to the welding machine
can not be stored. Each time power is applied to the equipment, all the parameters are
reset to initial values. Refer to Section 12.4, “ Replacement of batteries” for details.
9) E-700 Display
If “E-“ and “700” in the displays blink, it indicates the “Output overcurrent”.
If an overcurrent or short circuit on the secondary output continues for more than one second
during welding, the WARNING lamp lights up, “E-“ and “700” in the display blinks, then the
welding power source stops automatically. In this case, turn off the control power switch and
check to make sure that the welding current does not exceed the rated output value, or that there
is no short circuit on the output side such as a contact between the tip and the base metal, or a
short circuit of the output cables.
10) E-710 Display
If “E-“ and “710” in the displays blink, it indicates the “Lack of phase”.
If a lack of phase is detected at the primary input, the warning lamp will light up, “E-“ and “710” in
the displays will blink, and then the welding power source will stop automatically. In this case,
make sure that there is no lack of phase in primary input voltage.
11) E-800 Display
If “E-“ and “800” in the displays blink, it indicates the “Encoder in the wire feeder “.
If there is an error in an encoder feedback signal for detecting the feeding rate of wire feeder, the
warning lamp will light up, “E-“ and “800” in the displays will blink, and then the welding machine
will stop automatically. In this case, make sure that there is no damage in the encoder connector
(4P) on the top of the motor inside the wire feeder, the control cable for the wire feeder (10P),
and the printed circuit board P10261Q.
12) E-810 Display
If “E-“ and “810” in the displays blink, it indicates the “Thermal overload in the governor circuit “.
If thermal overload in governor circuit (printed circuit board P10261Q) is detected, the WARNING
lamp will light up, “E-“ and “810” in the displays will blink, and then the welding machine will stop
automatically. In this case, check for defective printed circuit board P10261Q, short circuit on the
motor power supply lines, rough feeding of wire, and error in the torch or the wire feeder.
