Troubleshooting
If problems persist beyond these troubleshooting points, please contact Excelitas Technologies
Service Department (refer to
Section 10
).
6.1 Failure to Power Up
If the Kepri unit fails to power up or function properly, use the following checklist to eliminate the most
common causes of problems. Check for the following:
•
Power Connection Check:
•
The power supply cord is securely connected to a grounded (earthed mains socket)
functional outlet.
•
The power supply cord is securely connected to the “Power” receptacle on the rear of the
Kepri unit.
•
The main power switch on the back of the unit is in the ON position.
•
Fuse Check:
•
Check both main power fuses. First disconnect the power cord, then carefully remove the
fuse tray assembly next to the AC receptacle on the rear of the unit.
Note
Depending on the orientation of the AC receptacle, the fuse tray may be below or
beside it. The red arrow in Figure 13
(A) shows where a flat screwdriver can be inserted to
gently pull out the fuse tray.

•
If either or both of the fuses are open, replace with the same type (F6.3A, 250V).
•
Note
To determine if a fuse is intact (i.e. OK) or open (i.e. blown), remove the fuse from
the tray and check with a
multimeter set to resistance (Ω). An intact fuse will read “0Ω” (or
another very low value), an open fuse will have an extremely high Ω reading.
•
Note
Fuses that chronically need to be replaced are usually a signal that something is
wrong and you should contact Technical Support.
•
Unit Door Check:
•
Verify the door screws of main unit are tight.
