Does the machine resume
correct operation after being

Probable overheating of
the motor. The machine is
OK
NO
Is the wiring between the
motor thermal cutout and
the inverter correct?
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
between their terminals. 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 cables on both the motor and inverter sides, and place the
tester probes at either end of each wire. The measured resistance should be 0 Ohm.
