If the AUMA Controller displays 'Fault of redundant wiring of Safe ESD input', it means that both signals Safe ESDa and Safe ESDb are not simultaneously on the same level. To solve this, check the redundant control of Safe ESD signals.
What does 'Actuator monitoring' mean on AUMA Controller?
If the AUMA Controller shows 'Actuator monitoring', it means the actuator locked during manual operation or there is a possible defect at the actuator. Contact AUMA service.
What to do if AUMA SQEx 05.2 Controller shows Torque fault CLOSE Torque fault OPEN?
If the AUMA Controller displays a torque fault in the CLOSE or OPEN directions, try executing the operation command in the opposite direction. Also, verify the torque switching setting and check for any foreign objects that might be preventing the valve from closing. There may also be problems with the valve itself.
What to do if AUMA SQEx 05.2 Controller reports a phase fault?
If the AUMA Controller indicates a phase fault, it means one phase of the power supply is missing, and the controls are not receiving mains voltage. To resolve this, test and connect the phases.
Why does my AUMA SQEx 05.2 Controller display 'Wrn controls temp'?
If your AUMA Controller displays 'Wrn controls temp,' it means the temperature inside the controls housing is too high and outside the specified range. Allow the controls to cool down. Also, check the service conditions.
How to fix 'Incorrect phase seq' on AUMA Controller?
If the AUMA Controller displays 'Incorrect phase seq', it indicates that the phase conductors L1, L2, and L3 are connected in the wrong sequence. Correct this by exchanging two of the phases.
What to do if AUMA Controller displays 'Thermal fault'?
If the AUMA Controller displays 'Thermal fault', it means the motor protection has tripped. Allow the system to cool down and wait.
What does 'Wrn range act.pos.' mean on my AUMA SQEx 05.2 Controller?
If the AUMA Controller displays 'Wrn range act.pos.', the current position feedback signal range is outside the permissible range, or both limit switches (OPEN and CLOSED) are operated simultaneously, or there is a possible defect at actuator mechanics. Verify the reduction gearing settings within the actuator. For possible defect at the actuator contact AUMA service.
What does 'IE 24 V AC' mean on my AUMA SQEx 05.2 Controller?
If the AUMA Controller displays 'IE 24 V AC', it indicates a fault in the internal 24 V AC power supply, meaning the safety-related part of the controls is without power. Check the power supply.
What to do if AUMA SQEx 05.2 Controller has no signal in display?
If the AUMA Controller display shows no signal, it indicates an internal error with the SIL module electronics sub-assembly. Contact AUMA service.
