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)
Place the tester probes across pins
1
and
2
on the connector
HD4
of receiver. The measured
value should be +5Vdc.
(2)
As for step
(1)
but across pins
1
and
6
of connector
CN4
(ARM Board) and on the
CN24
connector (CPU Board); of
CU223
cable.
(3)
Check the correct display SW version, according to the “EXCITE SW SMART TABLE” you
can find in
TG Direct
,“NEWS” section.
Check the grounding of the
HR/HS Receiver
, measuring the resistance value between:
a.
The fast-on on the
HR/HS Board
and the ground node on the power entry module;
b.
The ground node of the power entry module and the main wall socket.
T
he 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
(4)
Check that:
a.
The fast on of the cable are well connected to the HS plates;
b.
The continuity of the signal between the Hand Sensor plates and the relevant pin on
HD3&2 connector of the receiver, referring to the paragraph: 2.9. “Cables”;
c.
There is NO continuity between the HS plates and the ground fast on the receiver
(otherwise the signals are grounded).
