5.3 ERROR CODES
Internal faults during the operation of the Multiwash III result in error codes being reported on
the front panel display of the instrument. The table below lists the error codes and their
meanings. The Multiwash III should be turned off after the error code is recorded. Turning off
the Multiwash III resets the instrument and clears out the error code from the display.
Multiwash III
OPERATIONAL
ERROR CODES
Note: The instrument will show a 0, 1, or 2 in place of the
“?” shown on the instrument display.
?=0 is the pump, Max number of steps is 2272
?=1 is the horizontal axis, Max number of steps is 2400
?=2 is the vertical axis, Max number of steps is 350
E?1 No data An instruction was issued to move a stepper motor without data in the proper
register to specify how far to move. Check program and calibration
parameters and the Logic PCBA.
E?2 Incorrect signal from opto An instruction checking the status of the opto indicated that the status is not
correct for the following conditions:
Condition 1: Tried to move 5000 steps to the limit opto but the opto was never
blocked.
Condition 2: At the end of a move the opto should NOT be blocked, but it is.
E?3 No room from Limit An instruction has been received for a stepper motor to move away from it’s
Limit by more steps that are available. Check program and calibration
parameters and Logic PCBA.
E?4 No room to Limit A stepper motor reached its Limit opto before the requested move can be
completed. Check program and calibration parameters and the Logic PCBA.
E?5 Limit error A stepper motor reached its Limit opto before the requested move towards
Limit was completed. Check the stepper motors, stepper motor drive circuits,
Limit optos, and associated components on the Motor PCBA, 7360; Logic
PCBA, 7752 and the Limit Optos PCBA’s 8007.
E?6 Data range error The data for instruction is outside the capabilities of the unit. Check program
and calibration parameters and the Logic PCBA.
E?7 Already at max. An instruction has been received for a stepper motor to move away from its
Limit, but it is at its maximum position from Limit. Check the stepper motors,
stepper motor drive circuits, Limit optos, and associated components on the
Motor PCBA, 7360; Logic PCBA, 7752 and the limit Optos PCBA’s 8007.
E?8 Already at Limit An instruction was issued to move a stepper motor to Limit when it was
already at Limit. Check the stepper motors, stepper motor drive circuits, Limit
optos, and associated components on the Motor PCBA, 7360; Logic PCBA,
7752 and the Limit Optos PCBA’s 8007.
E?9 Valve time out No valve opto response has been received in the allotted time after a valve
movement instruction was issued. Check the valve motor, motor drive
circuitry, the valve position optos and associated circuits.
