Battery (5-1-2)
The Battery sub-menu shows:
• Voltage: The battery’s current voltage level.
A value of about 21V indicates a fully charged
battery and about 18V indicates a low battery.
• No of charges: The accumulated number
of charges where the battery has been fully
charged.
• Charge level : Shows the charge remaining
in the battery. When the battery is fully
charged, the charge is approximately
1,200 mAh. When the charge has dropped
to approximately 300 mAh the mower
returns to the charging station.
• Current: Shows nominal regulated charge
current to and from the battery. A positive
value indicates that the battery is charging
and a negative value indicates that the
mower is using current from the battery.
• Temp : Shows current temperature in the
battery.
Loop (5-1-3)
The Loop sub-menu shows:
• Signal quality : The loop signals can only be
interpreted if the value for Quality is 100%.
If the value is 99% or lower, the loop system
does not function correctly and thus none
of the values displayed for the signals are
correct.
• A signal, front : The strength of the A signal
measured via the front loop sensor on
the mower. The value should lie between
approximately 40 and 120 to ensure good
functionality. The closer to the loop the
mower is, the higher the value. When the
robotic lawnmower is directly over the
loop, the value is 0 and when the mower is
outside of the loop, the value is negative.
• A signal, rear : The strength of the A signal
measured via the rear loop sensor on the
mower. The A signal that is measured by the
rear loop sensor is normally higher than the
value from the front loop sensor.
• F signal : The strength of the F signal
measured via the front loop sensor. If the
mower is in test position (see “6.3 Loop
signal strength” ) the value for the F signal
should be between -100 and -300.
• Guide signa l: To ensure good functionality in
the guide wire, the value for the Guide signal
should be (-) 70 - 120 beside the guide wire.
Sensors (5-1-4)
The Loop sub-menu shows:
• Collision : One way of testing the collision
sensor is to hold the mower chassis by the
stop button and move the body forward and
back with the handle at the rear. The display
shows YES or NO . Continue to press on the
body until you see that both collision sensors
work.
• Lifted : To test the lift sensor, lift up the front
part of the body. When the body is lifted up
the lift sensor is activated and the mower’s
display shows YES. When the mower is in
lowered position NO is displayed.
•
Tilted X
: When the robotic lawnmower
is standing horizontally the value should
be max ±3. When the front wheels are
positioned higher than the rear wheel the
value is positive.
• Tilted Y : When the robotic lawnmower is
standing horizontally the value should be
max ±3. Inclination to the right gives a
positive value.
• Normal position: YES indicates that the
mower is standing in normal position and NO
that the mower is upside down.
Wheel motors (5-1-5)
The Wheel motors sub-menu displays the values in
two columns. The left column contains the values for
the left wheel motor and the right column for the right
wheel motor. The values displayed are:
• Speed : Measured in cm/s. Maximum speed
is 50 cm/s at 100% power.
• Current : Measured in mA.
• Power : Measured in %
• Voltage : Measured in volts. This value is the
same for right and left wheel motor.
Blade motor (5-1-6)
The Blade motor sub-menu shows:
• Speed : Nominal speed for the robotic
lawnmower is 2,900 rpm.
• Current : Measured in mA. When operating
the blade motor with blade disc and blades
fitted but without cutting grass, the normal
value is 380 mA +/- 100 mA.
• Voltage : Measured in volts.
