Operation
2.3.7 Charge status indicator
The charge status indicator (Fig. 14/1)
provides information on the current
charge status of the batteries up to the
total discharge limit. If the batteries are
fully charged when the vehicle is
switched on, all four fields light up under
battery icon. While the vehicle is in op-
eration, the fields go out according to
the discharge of the battery power.
When the top three fields have gone
out, the permissible low discharge level
is reached. The bottom field begins to
flash and an acoustic warning signal is
issued. All the cleaning units are
switched off after three minutes, the
vacuuming function following a 15 sec-
ond rundown time. The vehicle can then
be driven at reduced driving speed to a
charging point for the batteries. For in-
formation on charging the batteries, re-
fer to Section 2.3.2
If the vehicle is switched on, an
acoustic warning signal contin-
ues to be issued. When the
battery charging process has
been completed, the status is
cleared and the vehicle is
again ready to operate.
