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.
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:
(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).
P – N (phase – neutral) = 220Vac / 110 Vac
P – G (phase – ground) = 220Vac / 110 Vac
N – G (neutral – ground) = 0 Vac
