V
0…60
Field for entering a nominal value of accumulator voltage of
Vehicle (U
nom
=12V/24V) (see figures A.6 and A.7).
High Voltage
Level
1.29
-
0…1.99
Field for entering value of high voltage level of onboard
network (1.29▪U
nom
) (see figures A.6 and A.7).
Entered value of voltage is used as a threshold for recording
"Faulty ON"
Generator
Voltage
Level
1.16
-
0…1.99
Field for entering value of voltage level of generator, i.e.
when engine of Vehicle is running (1.16▪U
nom
)
(see figures A.6 and A.7).
Engine
Starter
Voltage
Level
0.91
-
0…1.99
Field for entering value of voltage level starter is running, i.i
when Vehicle’s engine is starting (0.91▪U
nom
)
(see figures A.6 and A.7).
Low Voltage
Level
0.75
-
0…1.99
Field for entering value of low voltage level of ON
(0.75▪U
nom
). Entered value of voltage is used as a threshold
for recording "Faulty ON" Event (see figures A.6 and A.7).
Battery Off
Level
0.20
-
0…1.99
Field for entering value of voltage level when ON switches
off (0.20▪U
nom
) (see figures A.6 and A.7).

5…30
Field for entering value of starter’s permissible time of
continuous operation, above which the starter may fail
(see figures A.6 and A.7).
Entered value is used as a threshold for recording
"Exceeding permissible time of continuous operation of
starter" Event.
