Troubleshooting
If the message “Calibration Failed” or “Levitation
Failed” appears when attempting to calibrate, it
indicates the steps expected by the SMT have
not been completed. To determine the cause of
failure, verify the following:
• Ensure there are no faults present; the shaft will
not levitate for validation if a fault is present.
•Ensure the RS485 at J1 on the I/O board is
disconnected from external communication;
if the chiller controller automatically sets the
control mode, it will stop the calibration process
prematurely.
• Ensure Interlock is open.
