Electronic Failure
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 stainer to “lose its place.”
If this occurs, switch the main power
OFF
for 10-20
seconds and then back
ON
to reset the instrument.
If the problem recurs, install a computer-type
surge protector to isolate the instrument.
If possible, connect the stainer to a power circuit
not shared by centrifuges, refrigerators, air
conditioners, or other motorized equipment.
For more obscure electronic problems, monitor the stainer
through a complete staining cycle to determine if the
operating sequence is correct. Do this by running the stainer
while watching the display and listening to the pumps.
Ensure that each event occurs according to the operating
sequence, shown in Table 13 in Appendix D.
If the problem recurs, contact your dealer
or ELITechGroup for assistance.
