Comments and suggestions
“F01” displayed
Drive motor of TissueLyser II
overloaded
When the drive motor is overloaded, the TissueLyser II switches itself off to allow
the drive motor to cool. A display on the TissueLyser II alternates between “F01”
and the remaining cooling time in minutes (e.g., “03” indicates 3 minutes).
After the cooling time has elapsed, switch the TissueLyser II off and then on
again before continuing to operate the instrument.
“F02” displayed
Drive motor of TissueLyser II not
starting
If the drive motor does not start after the “START” key has been pressed, contact
QIAGEN Technical Services to request instrument repair. The drive motor may
be blocked, or the motor or speed sensor may be defective.
“F03” displayed
Specified oscillation frequency
exceeded
If the specified oscillation frequency is exceeded, the TissueLyser II switches itself
off and “F03” is displayed. Contact QIAGEN Technical Services to request
instrument repair. The speed sensor may be defective.
“F04” displayed
Transparent hood not lowered
To protect the operator, the drive motor of the TissueLyser II will only start if the
transparent hood has been lowered. If the “START” key is pressed while the
hood is raised, “F04” is displayed and the drive motor does not start. If the
hood is raised while the TissueLyser II is in operation, the drive motor switches
itself off and “F04” is displayed. To cancel the “F04” display, press the “STOP”
key.
“F05” displayed
Keys held down for too long
If one or more keys on the keypad are pressed and held down for more than
15 seconds, the drive motor of the TissueLyser II switches itself off and “F05” is
displayed. This is a safety mechanism to prevent unwanted changes in the
operation of the TissueLyser II should an object land on the keypad. To cancel
the “F05” display, switch the TissueLyser II off and then on again.
“F06” displayed
Speed sensor defective
If one of the magnets controlling the speed of the TissueLyser II is missing or
defective, the instrument switches itself off and “F06” is displayed. Contact
QIAGEN Technical Services to request instrument repair.
“F07” displayed
Solenoid switch defective
If there is a defect in the cable for the solenoid switch, which monitors the
raising of the transparent hood, the TissueLyser II switches itself off and “F07” is
displayed. Contact QIAGEN Technical Services to request instrument repair.
