This inverter error message is related to the opening of the motor thermal cutouts.
Replace the inv erter
Follow the procedure step by step to correctly diagnose the problem. Take particular care with the
checks highlighted by circled numbers, which are described in detail below:
(1)
Disconnect the motor thermal cutout cables from the inverter and place the tester probes
across them. The measured resistance should be less than 1 Ohm.
In some cases the value may be higher due to oxidation of the contacts. To reinstate
correct operation, it is necessary to perform a special operation which will be described
to you on contacting the Technogym Service.
(2)
Disconnect the motor thermal cutout from the inverter: pin P24 and 3.
