Troubleshooting (continued)
Symptoms
Possible Causes and Comments
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
not moving freely. Typically this is caused by an obstruction,
which should be removed, but may be due to inadequate lubrica-
tion. Continued operation under these conditions can cause
damage to the instrument. Heads that are not moving freely may
be lubricated with light machine oil. Do not get 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 unit is not up to temperature. If the run was paused or the
door was opened, interlocks turn the heater o
ff
. After the run is
restarted and the door is closed, the heater should restart, and the
instrument should reach the set point temperature. If it hasn’t
reached the set point in a few minutes, there may be a problem
with the heater. Contact Promega or your local Promega represen-
tative for service. A heater problem may a
ff
ect yield.
Installed hardware does not match the dis-
played hardware mode
Turn the machine o
ff
and install the appropriate hardware as de-
scribed in Section 7.A. If the Magnetic Rod Assembly cannot be
removed because the Plunger Bar is too high, the Bar can be pushed
down until the Magnetic Rod Assembly can be removed or installed.
When the machine is powered up after the installation, the installed
hardware will match the hardware mode displayed on the
Home
screen.
Plungers are not completely stripped o
ff
the
rods at the end of the run
• 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; plungers that are reused may not be
completely removed at the end of the run. If plungers are con-
sistently left on by the instrument, contact Promega or your
local Promega representative for service.
The buttons do not work
Please contact Promega or your local Promega representative. Do
not use spray cleaner on the keypad or touch screen, because it can
damage the keypad or touch screen.
