Klein3000安装配置总结（二）

PROBLEM

CHECK

No operation, but the LOCK LOSS and

Carrier Loss lights are off.

Ethernet Hub.

LAN cables.

Path and location path to vxWorks.

Network setup on the computer and TPU.

TPU not functioning properly for no

apparent reason.

Check for proper AC voltage setting.

Check AC fuses.

Replace boards one at a time.

After a cable problem and the correction of

the cable problem, the CARRIER LOSS and

LOCK LOSS lights are on.

Check the towfish fuse.

Check the 200 VDC.

Check the TP7 and TP12 waveforms on

Multiplexer board.

Check the diodes in the hybrid circuit.

Replace the Demultiplexer board in the TPU.

After a cable problem and the correction of

the cable problem, the Carrier Loss and

Lock Loss lights are off, but the data on

SonarPro is breaking up.

Check that R30 is 4.7 ohms on the Multiplexer

board in the towfish.

Check U2 on the Demultiplexer board.

Change the Demultiplexer board.

Check diodes D7, D8, D9, D10 and check that

R11 is reading 4.7 ohms on the TPU 200 VDC

power supply.

After a cable problem and the correction of

the cable problem, the 200 VDC to the

towfish is reading around 300 VDC.

Check or change U1 on the TPU 200 VDC

power supply.

SonarPro operating slow over the network

with jittery display updates and large lag

numbers.

Incompatibility with the TPU CPU and the

vxWorks software. Check the CPU version in

the TPU and the version of vxWorks software.

CPU versions 14103184 can only be used with

vxWorks version 5.11.1841 or higher.

CPU version 14102073, recognized by

unpopulated area near front of board, can only

be used with vxWorks version 5.5.0291 or

earlier.

Contact L-3 Klein technical support for more

information.

TPU will not boot.

Error in boot line.

Gibberish data.

"Can’t load boot file!!" message.

Error messages.

The likely cause is the failure of the backup

battery on the CPU board.

Contact L-3 Klein for a replacement.

See “Replacing the CPU Battery” on page

C-62 for battery replacement instructions.
