Why does my AUMA Controller display 'Phase fault'?
The 'Phase fault' error on your AUMA Controller indicates that one phase of the power supply is missing, meaning the controls are not receiving mains voltage. To resolve this, test and connect all phases of the power supply.
What to do if AUMA SA 16.2 Controller shows 'Incorrect phase seq'?
If your AUMA Controller displays 'Incorrect phase seq', it means the phase conductors L1, L2, and L3 are connected in the wrong sequence. To fix this, correct the sequence by exchanging two of the phases.
What to do if AUMA SA 16.2 Controller displays 'Torque fault CLOSE Torque fault OPEN'?
The 'Torque fault CLOSE Torque fault OPEN' error on your AUMA controller indicates a torque fault in the CLOSE or OPEN directions, or simultaneously in both. Try executing an operation command in the opposite direction. Also, verify the torque switching setting and check for any foreign objects preventing the valve from closing. There may also be problems with the valve itself.
What does 'Wrn controls temp' mean on my AUMA Controller and how to fix it?
The 'Wrn controls temp' warning on your AUMA Controller indicates that the temperature inside the controls housing is too high, exceeding the specified temperature range. Allow the controls to cool down. Check the service conditions. You can view the current temperature display under Diagnostic M0022>Device temperatures M0524>Temp. controls.
How to resolve 'Thermal fault' on AUMA SA 16.2?
The 'Thermal fault' on your AUMA Controller is caused by the motor protection tripping. To resolve this, allow the system to cool down and wait.
What does 'IE 24 V AC' mean on my AUMA Controller and how to fix it?
The 'IE 24 V AC' error on your AUMA Controller indicates a fault in the internal 24 V DC power supply, meaning the safety-relevant part of the controls is without power. Check the power supply to resolve this issue.
What does 'Wrn range act.pos.' mean on AUMA SA 16.2?
The 'Wrn range act.pos.' warning on your AUMA Controller means the current position feedback signal range is outside the permissible range, or both limit switches (OPEN and CLOSED) are operated simultaneously. This can also indicate a defect in the actuator mechanics. Verify the reduction gearing settings within the actuator.
