RADIO TRANSMITTER
The transmitter
(see Figure 10)
is equipped with a
joystick, pushbuttons, and toggle switches for the
various functions. It runs on a 3.7V rechargeable
battery. The CAN port on the side of the transmitter
is used to charge the internal battery.
Figure 10
Enable Button
The ENABLE button is a built-in safety feature. By
default, the mower will not drive and will not engage
the PTO until the ENABLE button is pressed.
The system will remain in enable mode as long as
there is joystick movement. If no joystick movement
is detected for 10 seconds, the system will time out
and deactivate enable mode. The operator must
press the ENABLE button to reactivate the joystick
and PTO functions.
PTO Toggle
WARNING:
Avoid Injury
NEVER approach the machine with the PTO
toggle in the on position.
The PTO toggle switch turns the mower blades on or
off. The PTO switch will turn on the blades only when
in enable mode. If the PTO switch is on when the
ENABLE button is pushed, the system will ignore the
PTO switch. The operator must toggle the PTO switch
off and back on to turn on the PTO.
The PTO can be turned off by the toggle switch or
pressing the E-STOP button on the transmitter.
The PTO will automatically turn off when enable
mode is deactivated (i.e., after 10 seconds of no
joystick input).
When the E-STOP is pressed down on the
transmitter: both red and green lights will alternate
flashing for a few seconds and then go off once the
shut-down sequence is complete.
The red MACHINE WARNING indicator (left side near
HORN) provides operating error codes by blinking a
number of times followed by a brief pause.

Battery
When the battery is new, the run time of the
transmitter will be shorter until it has gone through
several discharge/charge cycles. After the initial few
cycles, the unit typically provides 20 or more hours of
run time before a recharge is needed.
The temperature that the battery is exposed to
affects performance and useful life. To maximize
battery life, keep the battery within the following
limits:
•
Charging: –4 to +86
°
F
•
Operating: –20 to +122
°
F
•
Storing: –4 to +86
°
F (lower is better)
The transmitter will go to sleep irrespective of
receiver status after 20 minutes (by default) if none of
the switches or buttons are pressed.
Battery Charging
The transmitter is designed with a smart battery
charger. The battery can be charged by plugging the
DC cigarette charger or optional AC wall charger
(minimum 2A at 12.6VDC) into the charging port. Red
