Hardware Troubleshooting Guide; Table 6.1 Hardware Troubleshooting - ILX Lightwave MPS-8033 Series User Manual

! ! ! !
This chapter is intended to be used as a guide when the MPS−8033 does not perform as expected.
It is not a service manual, rather a guide to alleviating basic problems that can arise during
operation.

Causes and Corrective Actions
Check the power cord to make sure that it is properly connected. Check the
•
fuse for integrity and proper rating.
If the above suggestions fail, check the line voltage selection.
•
Check the display for error messages when the (OUTPUT) ON switch is
•
pressed "on".
"E501" indicates an open interlock (The interlock is an internal jumper on the
•
8033 Analog Board).
"E529" through "E975" indicates that there is an internal hardware/software
•
communication problem which prevents the output from being enabled.
If GPIB is used, it is possible the Outoff register has been intentionally set to
•
disable the output on certain conditions or events. Refer to the
"ENAB:OUTOFF" command in Chapter 4.
It is possible an error condition occurred which turned the OUTPUT off, but the
•
error was corrected before the user read the message. Error messages are
displayed for three seconds or until the error causing condition is remedied.
The output connector may need cleaning. Clean the output fiber. See
•
Cleaning the Internal Fiber Optic Connector on page 79.
The 8033 may require calibration.The accuracy of the calibration is critically
•
dependent on the patch cord used and the loss that occurs at the fiber optic
connection with the 8033. Calibration is described in Calibration Overview on
page 76.
