7.6 CONTROLLO FUNZIONAMENTO
DELLA SCHEDA ELETTRONICA
A) Card supply
To make this test it is necessary to have:
– The key in the «ON» position
– Connector (1) connected to the card.
In this situation the pilot lamp should come on.
This check is done with the tester in Voltmeter func-
tion (Volt DC 0 ÷ 20), with the black ferrule on termi-
nal 1 and the red ferrule on terminal 11 of the wiring
connector (1).
The reading on the tester shows the battery’s vol tage.
B) Safety and service supply check
To make this test it is necessary to have:
– The key in the «ON» position
– Connector (2) connected to the card.
This check is done with the tester in Voltmeter func-
tion (Volt DC 0 ÷ 20), with the black ferrule to
earth
and the red ferrule on terminal 10 of the wiring con-
nector (2).
C) Checking the operation of the self-setting
protection
For this test, put everything in the same situation as
in point “A”.
By connecting terminal 10 of the connector (3) to the
frame’s earth, the pilot lamp should go out due to the
protection cutting in; eliminating the connection to
earth, the pilot lamp should come on again.
NOTE
During this test, the self-setting protection reaches
very high temperatures (around 160 °C) which are to
be considered normal. Similarly, there might be so me
smoke inside the transparent box which is due to the
overheating of the powder inside.
WARNING! Do not touch this component of the
card until it has cooled down.
