SECURITY MODES
For Codes 10814 and Below.
Both Low and High Security modes are provided to capture and
prevent changing of procedure settings. Both modes are acti-
vated, or deactivated by setting S1 DIP switch located inside
the DH-10 Control Box.
Low security mode is used to capture timer, acceleration and
control selections and settings, then to disable these selections
until low security mode is deactivated. Encoder knob setting
changes of cold feed, weld speed and weld voltage are not dis-
abled.
Low Security mode is activated, or deactivated, by shutting off
the input power to the DH-10 with all Timer and Control settings
as desired for both procedures for both Feeders. Then setting
S1 DIP switch 8 inside the DH-10 Control Box ON or OFF and
restoring input power (See "Low Security Mode Selection" in
this section).
When activated, the Timer and Control selections no longer
light, but function with the captured settings. All other keys and
encoder knob controls function normally.
NOTE: High Security mode must be OFF for Low Security
mode to function.
High Security mode functions the same as Low Security mode,
but the Voltage and Wire Feed Speed encoder knob controls
are also deactivated, including setting Cold Feed Speed (See
"Operation Keys" and "Trigger Mode Selection" in this section).
High Security mode can only be activated, or deactivated, by
shutting off the input power to the DH-10 with all settings as
desired for both Procedures for both Feeders. Then setting S1
DIP Switch 5, inside the DH-10 Control Box, ON, or OFF, and
restoring input power. (See "High Security Mode Selection" in
this section).
SECURITY MODES
For Codes 11433 and above
A security mode is provided to capture and prevent
changing of procedure settings. The mode is activat-
ed or deactivated by setting S1 DIP switch located
inside the DH-10 Control box.
Security mode is used to capture timer, acceleration,
and control selections and settings, then to disable
these selections until deactivated. Encoder knob set-
ting changes of cold feed, weld speed and weld volt-
age are not disabled. Limits setting can be used inde-
pendently to limit the allowed WFS and volts ranges.
OPERATION
Security mode is activated, or deactivate, by shutting
off the input power to the DH-10 with all Timer and
Control settings as desired for both procedures for
both Feeders. Then setting S1 DIP switch 5 inside
the DH-10 Control Box ON or OFF and restoring input
power (See previous Dip Switch views in this Section).
When activated, the Timer and Control selections no
longer light, but function with the captured settings.
All other keys and encoder knob controls function nor-
mally.
LIMITS SETTING MODE
For Codes 11433 and above
Limits setting mode is available for limiting the range
for setting wire feed speed and voltage. The limits
can be set independently for each feeder and proce-
dure. The following steps should be followed for set-
ting the maximum and minimum limits:
1. Turn off the power at the power source.
2. Remove the two screws at the top of the DH-10
control box and open the control box door.
3. Put DIP switch S1 switch 8 in the ON position.
(This switch is labeled "Limits")
4. Close the control box door.
5. Turn on the power at the power source.
6. The RUN-IN VOLTS/WFS light will be lit. Set the
maximum WFS and voltage limits for procedure B
for both feeder 1 and feeder 2 using the two
encoder knobs and the feeder and procedure
keys. The maximum WFS limit can be set for the
entire range of the wire drive that is being used.
(This can be different for each feeder.) The maxi-
mum voltage limit can be set over the range of
10.0 to 60.0 volts. The maximum limits can be
turned off independently for each feeder and pro-
cedure by turning the encoder knobs clockwise
until the appropriate display (WFS or voltage)
reads "OFF" while the correct feeder and proce-
dure lights are lit. (The limits are set to "OFF"
from the factory.
7. Press the CONTROL key on the keypad. The
RUN-IN VOLTS/WFS light will be off. (Settings
can be toggled between minimum and maximum
limits by repeatedly pressing the CONTROL key.
When the RUN-IN VOLTS/WFS light is lit, maxi-
mum limits are being set. When the RUN-IN
VOLTS/WFS light is off, minimum limits are being
set.)
