GROUNDING LEAD PROTECTOR
The frame of the DH-10 Control is grounded to the
frame of the power source by a lead in the control
cable. An overload protector prevents welding current
from damaging this lead if the electrode circuit touch-
es the wire feeder frame while the electrode is electri-
cally hot.
If such a grounding lead fault occurs, the WFS display
will show “GLP,” (with blank Voltage display) and the
trigger circuit will be disabled. To reset the circuit,
release the trigger, make sure that the electrode is not
touching the wire feeder frame, and then either press
any key on the keypad or close the trigger. When the
GLP circuit is reset, the “GLP” display is removed and
the wire feeder is returned to normal operating mode.
EXPLANATION OF PROMPTING
AND ERROR MESSAGES
Display
Prompt or Error
Acc
Displayed on Voltage display, indicates WFS
display is showing acceleration setting, “1” to
“5” (see
Acceleration Selection in this
section).
SEC
Displayed on WFS display, indicates Voltage
display is showing a Timer setting in sec-
onds. (See
Display Control Keys in this
section.)
GLP
Displayed on WFS display, indicates that the
Grounding Lead Protector circuit was
activated due to excessive current flow into
the wire feeder frame. When the GLP circuit
is activated the wire feeder is disabled (the
trigger output to the power source is opened
up, the motor is stopped, and the gas
solenoid is turned off). To resume normal
operation, release the trigger, make sure that
the electrode is not touching the wire feeder
frame, and then either press a key on the
keypad or close the trigger. (See
Grounding Lead Protector in this section.)
Cld
Displayed on Voltage display when Cold
Feed Forward or Cold Feed Reverse Key is
pressed, or Cold Feed Trigger mode is
selected. Indicates wire is fed “cold” (no
weld voltage) at the speed indicated on the
WFS display. (See
Operation Keys and
Trigger Mode Selection in this section.)
---
Displayed on Voltage or WFS displays with
RUN-IN selected, indicates setting will match
those set for Weld Voltage and Wire Feed
Speed. (See
Display Control Keys in this
section.)
HXX
Displayed on WFS display, indicates wire
feed overload. XX indicates time remaining in
seconds before unit resets automatically.
(See
Wire Feed Overload Protection in this
Problems in the Maintenance section.)
Er
EEPROM error. Usually occurs at power-up.
Indicates one or more of the recalled settings
is out of acceptable limits. Press any key to
return to normal operation. Be sure to check
all voltage, wire feed speed, acceleration and
timer settings before you proceed.
