Interruption
of power supply
Meaning / Cause
:
An interruption of the supply voltage of the motion sensor
longer than 200 ms has been detected and reported by the
motion sensor.
Measures
:
y Measure the supply voltage of the motion sensor at the pins
B1 and B2. The value must be between 6.5 V and 9 V.
y Check the corresponding plug connector (B-connector of
EFAS and connector on the motion sensor).
y Check the contacts and wires for damaged spots and
contact problems.
S4 13 - - 80 00 000007
- - - Meaning / Cause
:
The supply voltage of the EFAS exceeds the maximum per-
missible operating voltage (see technical data and type label
of EFAS). EFAS checks this voltage cyclically several times per
second.
Measures
:
Measure the supply voltage of the EFAS at the pins A1, A3, A5,
A6 or terminals 30, 15, 31a, and 31 and compare these with the
specifications in the technical data or the type label of EFAS.
S5 13 - - 80 00 000003
- - - Meaning / Cause:
The supply voltage of EFAS is below the minimum permissible
voltage value. EFAS checks this voltage cyclically several times
per second.
Measures
:
Measure the supply voltage of EFAS at the pins A1, A3, A5, A6 or
terminals 30, 15, 31a, and 31 and compare these with the specifi-
cations in the technical data or the type label of the tachograph.

Interruption
of power supply
Meaning / Cause
:
An interruption in the supply voltage of EFAS greater than
200 ms has been detected. An interruption can be caused by an
under-voltage or over-voltage or voltage drop.
Note
:
After the occurrence of voltage interruption, EFAS can be reset
only when proper supply voltage is available at the recording
equipment for a period of at least one minute.
Measures
:
Measure the supply voltage of EFAS at the pins A1, A3, A5, A6
and terminals 30, 15, 31a and 31.
Check the contacts of the A connector as well as the supply lines
to EFAS.
13 The EFT for this event or the malfunction is not stored to the mass memory in the CALIBRATION operating mode. Information appears in the display with the specification of the
SrvID that this event or malfunction has been detected for a short duration.
