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:
c. The Faston on Receiver Board and the ground node on the equipment;
d. The ground node on the equipment and the main wall socket t.
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
(2) Check if the receiver has been correctly mounted on the machine, as detail at paragraph: 7.4.
“Disassembling the cardio receiver”.
(3) Place the tester probes across pins 1 and 2 of CN1 connector of receiver. The measured value
should be +5Vdc.
(4) As at step (3) but on pin 1 and 8 on CN3 connector (ARM Board) and on CN29 connector
(CPU Board) .
If you replace CPU/ARM Board, check that its SW version is updated, otherwise
install the last version.
