G4FUSE may cause intermittent G4 output module operation
Revision:  2.0
Published:  4/24/2006
Applies To
All G4 output modules
Versions

SYMPTOMS

G4 output modules may operate intermittently.

CAUSE

The G4FUSE leads may not be inserted into the fuse sockets properly. If you are experiencing intermittent output operation from a module, inspect the G4FUSE leads. Remove power from the module and pull out the fuse if necessary. Verify the leads are not bent or broken.

RESOLUTION

The fuse insertion problem has been corrected.

The problem was found in some modules dated September 2005, or manufacture date code “JEXXXXXXCF”, as printed on the side of the module. The following instructions explain the Build Code.

  1. The first two characters in the Build Code is the year of manufacture. The last two characters in the Build Code is the week of manufacture.

  2. The year and week is decoded by the following chart:

  3. 1 = A 3 = C 5 = E 7 = G 9 = I
    2 = B 4 = D 6 = F 8 = H 0 = J

In the above example JE is 05 (2005) and CF is the 36th week of the year (September).

If you are experiencing intermittent behavior due to the described issue, contact Opto 22 Product Support for replacement fuses.
