RECOMMENDED

COURSE OF ACTION

Device goes off line during welding.

1. Interference / Noise.

1. Verify that DeviceNet cables are not

 

 

 

running next to (in close proximity

 

 

 

with) current carrying conductors.

 

 

 

This includes the welding cables, input

 

 

 

cables, etc.

 

 

2. Termination.

2. Verify that the DeviceNet bus is termi-

 

 

 

nated correctly.

 

 

3. Shielding.

3. Verify that the cable shielding is cor-

 

 

 

rectly grounded at the bus power sup-

 

 

 

ply. The shield should be tied into the

 

 

 

bus ground at only one point.

 

 

4. Power Supply.

4. Verify that the DeviceNet bus power

 

 

 

supply can supply sufficient current for

 

 

 

the devices on the network.

 

 

 

 

 

 

5. Expected Packet Rate.

5. Verify that 1000/(Expected Packet

 

 

 

Rate) ≤ (scans per second). The

 

 

 

DeviceNet tab of the Diagnostics

 

 

 

Utility displays these values.

 

 

 

 

Output will not come on.

1. DeviceNet trigger not asserted.

1. From the DeviceNet tab of the

 

 

 

Diagnostics Utility, select Monitor. The

 

 

 

Monitor window will be displayed. Verify

 

 

 

under the “Produced Assembly” that

 

 

 

“Trigger” is highlighted.

 

 

2. Touch Sense command.

2. From the DeviceNet tab of the

 

 

 

Diagnostics Utility, select Monitor. The

 

 

 

Monitor window will be displayed. Verify

 

 

 

under the “Produced Assembly” that

 

 

 

“Touch Sense” is NOT highlighted.

 

 

3. Passive Mode.

3. The DeviceNet tab of the Diagnostics

 

 

 

Utility displays the POWER WAVE®ʼs

 

 

 

passive mode status. If the status

 

 

 

needs to be changed, select Configure,

 

 

 

and make the necessary modification.

 

 

 

 

 

 

4. Welding Cables.

4. Verify that welding cables are connect-

 

 

 

ed properly.

 

 

5. Output Disabled

5. From the DeviceNet tab of the

 

 

 

Diagnostics Utility, select Monitor. The

 

 

 

Monitor window will be displayed. Verify

 

 

 

under the “Produced Assembly” that

 

 

 

“Disable Output” is NOT highlighted.

 

 

 

 

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.
