Code Probable Causes
autocalibration. Carrier jig installed backward. Oil film on gold-plated jig not
allowing contact to be made. Jig connector not making contact or pulled out of
connector. Destination stack not installed correctly. Lead screw unglued from
motor. Destination lift motor or driver circuit defective. Linear way jam
causing motor to lose steps.
0300 One or both Stack Locks are open. Always lock the stacks before operation.
040# Failed positional verify. # = motor; see page 87 for a list of motor numbers.
This error indicates that an axis failed its positional verify test. After moving
a predefined number of steps from a home position, the motor should return
to the home position in the proper amount of time and steps. If the axis
moves back to its home position in the wrong amount of time, or uses too few
or too many steps, the test fails. A belt may be slipping due to incorrect
tension, a loose motor pulley, or a loose belt clamp. This can also be caused
by a defective motor drive circuit. Gripper motor error (0407): If the
BioStack2WR is not on, its gripper falls to the fully down position. When the
interfacing instrument is powered on and goes through its normal homing
sequence, the BioStack gripper gets in the way and causes the attached
instrument to error. The solution is to power up the BioStack first and keep
the BioStack powered on. If the BioStack is powered off, raise the
claw/gripper assembly manually above the interfacing instrument's carrier
before powering on. Once its initialization is complete, then power on the
interfacing instrument.
040D Destination lift motor could not find opto sensor. Occurs during
autocalibration. Carrier jig installed backwards. Oil film on gold-plated jig not
allowing contact to be made. Jig connector not making contact or pulled out of
connector. Destination stack not installed correctly. Lead screw unglued from
motor. Destination lift motor or driver circuit defective. Linear way jam
causing motor to lose steps.
055# Motor in use error. # = motor; see page 87 for a list of motor numbers. An
internal programming error. A command was issued to move a motor that
was already in motion. Turn the instrument off/on. If the error persists,
contact BioTek TAC.
0600 Calibration data missing. Nonvolatile calibration data may be missing or
corrupt. One or more components of the instrument may need to be
recalibrated. Turn the instrument off/on, and if the error persists, contact
BioTek TAC.
0650 Autocal jig placement error. The autocal jig was installed incorrectly. Position
the jig correctly and retry.
0700 Failed interface configuration checksum test. Nonvolatile configuration data
associated with the external instrument interface may be missing or corrupt.
Turn the instrument off/on. If the error persists, contact BioTek TAC.
