Error theta-axis
motor or sensor
Problem: The confidence test has detected that
the q-axis (rotation) motor is not
running properly or that rotation of the
turret is not being sensed by one of the
q-axis sensors.
Solution: When the confidence tests finish, try
moving the q-axis motor by pressing
the ROTATE CW and ROTATE
CCW keys. If the turret assembly
does not move, the motor needs to be
serviced. If the turret moves, test the
q-axis sensor with the TEST key (see
page 6-9). If the sensor is malfunc-
tioning, have the sensor serviced.
Error
Watchdog Timer
Problem: The watchdog timer is taking too long
to time out during the confidence tests.
Solution: Turn off the Autosampler CE, and
power up again. If you still receive this
message, call a qualified service
representative.
