and green lights near the charging port of the
transmitter indicate the status of the charger:
•
Red light indicates battery is charging
•
Green light indicates battery is fully charged.
Low Oil Pressure
The machine is capable of detecting a low oil
pressure condition. This feature only activates after
the start button is pressed. If the start button is
pressed and the engine does not start, the RC system
may be detecting a low oil condition and begin the
warning sequence outlined below.
Low oil pressure detected:
•
After 20 seconds: the machine warning light
blinks two times, the horn will sound for
1 second every 4 seconds.
•
After 40 seconds: the machine warning light
stays on continuously, the horn will sound for
5 seconds continuously and the machine will
shut down.
INCLINOMETER (MACHINE ANGLE)
The machine has a built-in inclinometer which
constantly measures the machine tilt angle in all
directions. This safety device provides operator
feedback, machine protection, and automatic
shutdown when certain hazardous conditions are
detected.
If the machine inclinometer measures an angle
of 30 degrees in one direction for more than
10 minutes, the machine warning light blinks
4 times. After 13 minutes it will turn on the horn for
2 seconds every 30 seconds. After 20 minutes it
will go to E-stop mode. If the angle goes under
30 degrees or switches direction for at least
5 seconds, the system returns to normal. This
function is to protect the engine from excessive run
time in a single orientation.
If the machine inclinometer measures an angle of
53 degrees or more, the machine warning light blinks
5 times, the horn will sound for 3 seconds every 10
seconds, and the PTO will automatically turn off.
Once the angle goes under 53 degrees for
more than 5 seconds, the system returns to normal.
This function is intended to warn and inhibit the
operator when attempting to climb beyond the ability
of the machine.
If the machine inclinometer measures an angle of
70 degrees or more (i.e., a rollover accident), the PTO
and engine will automatically turn off. The machine
warning light blinks 6 times and the horn will sound
continuously for 30 seconds. Pushing the
E-STOP down on the transmitter will stop the horn.
This function is intended to shut down the machine
and warn the operator and any bystanders of
imminent danger should a rollover incident occur.
RADIO RECEIVER
The system’s radio receiver (
see Figure 11
)
communicates with the transmitter and directly
controls the functions on the mower unit. It includes
a port for RS-232 communication for system
diagnostics.
Figure 11
Each of the outputs from the receiver module is
designed with built-in short circuit and overload
protection. The outputs can also detect a no-load or
broken wire condition.
When activated (or turned on), the ON/OFF outputs
will indicate an error if a short is detected. When NOT
activated, the ON/OFF outputs will indicate an error if
the item is disconnected or has a broken wire. The
actuator outputs will detect either a no-load or short
condition when activated by the joystick.
These error conditions are indicated by the red LED
light.
