Friendly Robotics robomow rl350 Operating Manual page 47

Problem Encountered
'Replace Battery' indicator
flashing on Perimeter Switch
Robomow will not operate and
nothing will display on the
LCD screen.
Robomow drives but blades
will not mow.
Short run time, operates less
time than normal.
Robomow operating lamp
flashes once when Power
Pack is inserted, but no
display is seen in the LCD
display.
Probable Cause/Event
- Weak batteries
- Poor wire splicing (confirm that
when the Perimeter Switch is turned
on, first the 'Cut wire' indicator is
flashing once).
- Twisted cables, or a screw terminal,
insulated with insulation tape is not
a satisfactory splice. Soil moisture
causes the conductors to oxidize
and after a while result in broken
circuit.
- Perimeter wire too long for one
zone
- Mower is in deep sleep.
- Power Pack has been discharged
from lack of charge maintenance.
- 'Mowing 'has been turned to off.
- Power Pack is not fully charged
- 'Work Time ' for that zone is set to
stop at a pre-determined duration.
- Grass is extremely over grown or
very wet.
- Power Pack is reaching a normal
end of life state.
- Manual Controller is not firmly
pivoted down flush in holder,
allowing it to bounce up and stop the
mower.
- Power Pack fuse has not been
installed.
Corrective/User Action
- Install fresh alkaline C-cell batteries
- Use the connectors supplied in the box. It is
waterproof and gives a reliable electrical
connection.
- A maximum perimeter wire length of 1000 feet
(300 m) is recommended. Areas requiring
longer lengths should be broken into separate
zones. If the 'Cut Wire' indicator flashes once
when the Perimeter Switch is activated, this
confirms a length too long for a single
perimeter zone.
- If not connected to the Power Supply at all
times when not in use, the Robomow will
conserve power by entering into a deep sleep
mode. Lift Power Pack from mower and re-
insert it after 10 seconds.
- It is required for the Power Supply to remain
connected to the Robomow when not in use.
Failure to do so can cause permanent Power
Pack damage. Contact your service provider.
- Change back on under 'User Preferences'
- Connect the Power Supply to the mower and
keep it connected until the 'Ready – Keep
Charging' message displays in the LCD
screen.
- Work time can be changed under 'User
Preferences'
- Raise cutting height. Always mow the grass
frequently enough to prevent over growth.
Refrain from cutting wet grass.
- Replace Power Pack. Properly maintain Power
Pack per instructions.
- Confirm the coiled cord is fully placed into the
holder below the Manual Controller and the
Manual Controller closes flush with the top of
the mower.
- Install Power Pack fuse.
