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.
