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 of the HD4 connector of the receiver on CU319
cable. The measured value should be +5Vdc.
(2) As at step (1) but on pin 1 and 5 on CN22 connector of the Display Board.
(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 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:
(4)
Check that:
a. The faston of the cable are well connected to the Hand Sensor plates;
b. The signal continuity of the CU323 cable, which connect the HS plates to the HD3&2
connectors on the receiver, using a tester and referring to the paragraph: 2.10.
"Cables";
c. There is NO continuity between the Hand Sensor plates and the ground faston on the
receiver (otherwise the signal are grounded).
P – N (phase – neutral) = 220Vac / 110 Vac
P – G (phase – ground) = 220Vac / 110 Vac
N – G (neutral – ground) = 0 Vac
