YES
A
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) Check the correct display SW version, according to the “EXCITE SW SMART TABLE” you
can find in TG Direct section.
Check the grounding of the HR Receiver Board, measuring the resistance value between
a. The ground faston of Receiver Board and the ground node on the Power supply box of
the machine;
b. The ground node on the Power supply box of the machine and the main wall socket.
The measured value should be approximately lower than 1Ω (Ohm).
Check finally the grounding of the main wall socket, measuring that the following voltages are
present:
P – N (phase – neutral) = 220Vac / 110 Vac
P – G (phase – ground) = 220Vac / 110 Vac
N – G (neutral – ground) = 0 Vac
