Instrument configuration has been changed to Research or Forensic mode. Confirm the
configuration by turning the instrument off and then on again (See Section VIII.A). To
change the operational mode and hardware settings, follow the directions in Section
VIII.A(ii), selecting “Clinical” from the Operational Setup screen, and “SEV”from the
Hardware Setup screen.
The instrument is making an
unusual, rapid clicking noise
when it is turned on.
•
Verify that the Magnetic Rod Assembly/Plunger Bar shipping anchors and Platform shipping
anchors have been removed.
•
One of the machine sensors might have a dust particle interfering with it. Contact Promega or
your local Promega representative for assistance with sensor cleaning.
The LCD screen does not light
up when the instrument is
turned on.
If you
cannot
hear the motors running:
•
Check that the unit is plugged into a working electrical outlet
•
Verify that the plug is securely connected to the back of the instrument.
•
A 3-amp fuse protects the instrument electronics and is located next to the power switch. If
the fuse is blown, identify and correct the cause. Never replace this fuse with a fuse rated for
an amperage higher than 3A.
•
Contact Promega or your local Promega representative for service.
If you
can
hear the motors running:
•
Either a cable has become disconnected from the LCD screen, or the LCD screen is broken or
damaged. Contact Promega or your local Promega representative for service.
The machine makes unusual
noises during the run.
The machine will make some noise during a typical run. Unusual (or louder than usual) noises
may indicate that the heads are sticking. Continued operation under these conditions can cause
damage to the instrument. Heads that are sticking may be lubricated with
light
machine oil. Do
not get any oil on the drive belts. Use a small amount of oil on a cotton swab. If this does not
correct the problem, contact Promega or your local Promega representative for service.
Heater error at the elution step. The electrical heating system is not working properly. Contact Promega or your local Promega
representative for service.
Plungers are not completely
stripped off the rods at the
end of the run.
Always be careful to check that plungers are clear of the magnetic rod assembly before
extending the platform out from inside the instrument. If the problem occurs consistently, check
that the magnetic rods are clean. Wipe them down carefully with a damp cloth. Do not reuse
plungers. If plungers are consistently left on, contact Promega or your local Promega
representative for service.
