1. FUNCTION
If the control box is blocked, for example, by
unintentionally interrupting programming, battery charging
is not monitored. It is then important that you charge the
Automower
®
with caution, that is to say, for no more than
10 minutes. A blocked control box is characterised by no
text being shown on the display/no LEDs are lit and the
keypad does not work despite the battery being charged.
1.12.1 Battery check
If the mower's battery starts to deteriorate the
Automower
®
will mow for shorter periods. The mower
can also stop and display the fault message Low
battery voltage (Does not apply to 210 C). A battery
check is recommended in order to establish whether
the battery is spent (For 210 C it is sufficient to run the
mower as usual).
It is also recommended to make a battery check with
the winter service of the mower. A spent battery can
then be changed before the next season starts.
In order to check the capacity of the battery it is
necessary for the battery to be fully discharged. Use
manual operating mode and charge the battery fully.
When charging starts the battery temperature should
not be more than 40 ºC (104 ºF). Now let the
Automower
®
mow in manual operating mode until the
battery is fully discharged. It is also possible to switch
the mower from automatic to manual operating mode
when it has left the charging station and started to
mow. The mower ought to have a slight mowing
resistance during the ongoing battery check. The
cutting height should therefore be adjusted to the
maximum cutting height.
If the mower has not been in operation for several
weeks when the check is made, for example if the
mower has been left for its winter service, at least two
or preferably three battery checks ought to be made.
The assessment should be based on that last made
check as the first check can indicate an incorrect value.
The four most recent battery tests are saved in the
mower. Read the tests from Autocheck, operating
history, or Battery history (shortcut 5-1-5) in the mower.
For models 230 ACX and 260 ACX, which have two
batteries, the individual capacity of each battery is
shown (this is also the case for the 210 C, which is
equipped with two batteries). Accordingly, it is possible
to determine whether one or both batteries should be
replaced. On Solar Hybrid the energy that the solar
panel has supplied during manual operating time is
also shown.
In cases where a battery test cannot be performed on
an installation, the test can be performed directly on
the work bench via Autocheck (see 4.8.2 Manual test
on page 68). The test is performed as above, except
the mower's driving wheel and blade disc rotate freely
during the test. Since resistance to the wheel drive and
blade disc is in principle non-existent, discharging the
battery/batteries may take several hours.
