Self-diagnosis

The electronics of the KTCO 1318 contin-
uously checks the instrument for
–

power loss

– failures of the pulse generator
system.
5.1 Power loss (Figure XII)
In case of power loss the instrument
stops operating.
If voltage is applied again and if there is
no handling error, i.e. tachograph chart
inserted, cover correctly closed, the
tachograph will behave as follows when
the vehicle is started:
– The vehicle speed pointer (2) will
rise to full-scale value (4) and
immediately go back to zero (1).
– This will be recorded by the vehicle
speed stylus on the tachograph
chart as a stroke (5).
Note
If the battery has been disconnected for
repair, please don't forget to set the cur-
rent time.
