Lincoln Electric POWER WAVE IM718 - Manual (Page 16)

EXTERNAL I/O CONNECTOR
The Power Wave is equipped with a terminal strip for
making simple input signal connections. The terminal
strip is located underneath the spring-loaded cover. It
is divided into three groups: Trigger group, Cold Inch
Group and Shutdown Group. Because the Power
Wave is a
‘ slave ’ on the DeviceNet network, the
Trigger and Cold Inch Groups are disabled when the
DeviceNet/Gateway is active.
The shutdown group is always enabled. Shutdown2 is
used for signaling low flow in the water cooler.
Unused shutdowns must be jumpered. Machines from
the factory come with the shutdowns already
jumpered. (See Figure A.5)

HIGH SPEED GEAR BOX
Changing the ratio requires a gear change and a PC
board DIP switch change. As shipped from the facto-
ry, the low speed (high torque) gear is configured. To
change the gear ratio see the Wire Feeder Instruction
Manual. The High/Low DIP switch code on Wire Drive
PC board can be set as follows:
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts
or electrodes with your skin or wet
clothing.
• Insulate yourself from the work and
ground.
• Always wear dry insulating gloves.
-----------------------------------------------------------
1. Turn off power to the power source at the dis-
connect switch.
2. Remove the front cover from the power source.
3. The wire feed head board is on the right side of the
power source. Locate the 8-position DIP
switch and look for position 8 of the DIP
switch.
4. Using a pencil or other small object, slide
the switch to the OFF position, when the
low speed gear is installed. Conversely,
slide the switch to the ON position when
the high speed gear is installed.
5. Replace the cover and screws. The PC
board will "read" the switch at power up, automati-
cally adjusting all control parameters for the speed
range selected
