SOLVING PROBLEMS
5.1 Troubleshooting
This section helps you identify and solve routine problems with the Cytopro. More difficult problems
may require technical service. Contact your Elitech Group representative for assistance.
WARNING!
Due to the electrical shock hazard, do not open this instrument or attempt internal repairs. Refer
servicing to qualified service personnel. Contact your dealer or Elitech Group Service.
Table 7: General Troubleshooting and Diagnosis
There is no power to the instrument when the power
switch is turned ON.
Check the facility outlet and the power cord connection.
Check the fuses. Refer to the Replacing Fuses procedure.
CAUTION:
Fuse failure may indicate a serious internal problem.
Strange information shows on the display, and/or erratic
instrument operation.
Switch the instrument OFF, wait 10 to 20 seconds, then
switch power ON again. If problem recurs, install a
computer-type surge suppressor to protect the
instrument from power line transients. If possible,
connect the instrument to a power circuit that is not
shared by centrifuges, refrigerators, air conditioners, or
other motorized equipment.
If the above steps do not solve the problem, consult the
Service Manual, or contact your dealer or Elitech Group
for assistance.
An electronic failure would appear as an obvious
malfunction such as a scrambled or totally inoperative
display panel.
Transient voltages coming through the power lines may
cause the device to “lose its place.”
1 If this occurs, switch the main power OFF for 10-20
seconds and then back ON to reset the instrument.
2 If the problem recurs, install a computer-type surge
protector to isolate the instrument.
3 If possible, connect the device to a power circuit not
shared by centrifuges, refrigerators, air conditioners,
or other motorized equipment.
If the problem recurs, contact your dealer or Elitech
Group for assistance.
