Lincoln Electric POWER WAVE R500, Operator'S Manual, Page: 20 / 56

3. FEEDER STATUS LED - A two color LED that indicates
system errors. The Power Wave R500 is equipped with two
indicators. One is for the inverter power source, while the
other indicates the status of the feeder control system.
Normal operation is a steady green light. For more informa-
tion and a detailed listing, see the troubleshooting section of
this document or the Service Manual for this machine.
(See
Troubleshooting Section for operational func-
tions.)
NOTE: The Power Wave R500 status light will flash green, and
sometimes red and green, for up to one minute when the
machine is first turned on. This is a normal situation as the
machine goes through a self test at power up.
4. POWER SWITCH - Controls power to the POWER WAVE ®
R500.
5. NEGATIVE WELD OUTPUT
6. POSITIVE WELD OUTPUT
7. VOLTAGE SENSE CONNECTOR: Allows for sepa-
rate remote electrode and work sense leads.
