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 CN1 connector of receiver. The measured value
should be +5Vdc.
(2) As at step (1) but on pin 1 and 8 on CN23 connector CPU Board.
(3) 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:
a. The Faston on Receiver Board and the ground node on the equipment;
b. 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:
(4) Check if the receiver has been correctly mounted on the machine.
If you replace CPU Board, check that its SW version is updated, otherwise install the
last version.
