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 receiver board, measuring the resistance value between:
a. The ground fast on of HR/HS Board and the ground node on the Power supply box of the
machine;
b. The ground node on the Power entry module and the main wall socket.
The measured value should be approxim ately 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
(2) Set the HR priority on the receiver board on “Hand Sensor”, by positioning the jumper ( JP1 )
on the receiver itself:
JP1 CLOSED
= Chest strap priority
JP1 OPENED = Hand Sensor priority
The standard configuration of the receiver is with chest strap priority.
(3) Check that:
c. The fast on of the cable are well connected to the HS plates;
d. The continuity of the signal between the Hand Sensor plates and the relevant pin on
HD3&2 connectors of the Receiver, referring to the paragraph: 2.9. “Cables”;
e. There is NO continuity between the HS plates and the ground fast on the receiver
(otherwise the signals are grounded).
