POSSIBLE AREAS OF MISADJUSTMENTS(S)

RECOMMENDED

COURSE OF ACTION

16.Wire feeder's display does not change when WFS and/or Volts/Trim knobs of the remote control kit are turned.

a. Loose connection to Remote con- trol receptacle, J22.

b. Faulty Remote PC board.

c. Faulty remote cable.

d. Faulty remote wiring harness.

e. Faulty wire feeder harness or remote cable receptacle.

f. Faulty Control board or Remote PC board.

a. Make sure that remote cable connec- tions are tight.

b. If either the WFS knob, the Volts/Trim knob, or the dual procedure switch of the remote control kit is operating properly then replace the Remote PC board.

c. Remove remote cable from wire feed- er and unplug connector P2 from J2 in remote control kit. Check continuity between pin 1 of J2 and socket B of remote receptacle, between pin 2 of

J2 and socket A of remote receptacle, between pin 3 of J2 and socket D of remote receptacle, and between pin 4 of J2 and socket C of remote recepta- cle. If any of these continuity tests fail then repair or replace remote cable.

d. Remove plug from J1 on Remote PC board and unplug connector P2 from J2 in remote control kit. Check conti- nuity between pin 1 of P2 and pin 2 of P1, between pin 2 of P2 and pin 3 of P1, between pin 3 of P2 and pin 4 of P1, and between pin 4 of P2 and pin 5 of P1. If any of these tests failed, repair or replace remote wiring har- ness.

e. Remove plug from J3 on Control board of wire feeder and remove remote cable from wire feeder. Check continuity between socket A of remote receptacle J22 and pin 2 of plug P3, between socket B of remote recepta- cle and pin 1 of plug P3, between socket C of remote receptacle and pin 3 of plug P3, and between socket D of remote receptacle and pin 4 of plug P3. If any of these tests failed then repair or replace wiring harness. Check continuity between either of the four pins of receptacle J22. If there is continuity between either of the pins then receptacle is faulty.

f.Try replacing Remote PC board. If this does not solve the problem then replace Control board of wire feeder. (See procedure for replacing PC boards.)

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your Local Lincoln Authorized Field Service Facility for technical troubleshooting assistance before you proceed.
