Electrical System
Remote Transmitter (Machines with Single Channel Controller)
NOTE: Machines with a single channel controller can
be identified by the external antenna on the control mod-
ule (Fig. 15).
The remote transmitter is a solid state electrical device
that sends radio frequency (RF) signal inputs to the ma-
chine control module for control of machine electrical
operation (Fig. 15). The remote transmitter has suffi-
cient range to send an RF signal to the control module
from the tow vehicle operator position.
Whenabuttonontheremotetransmitter is pressed, the
LED on the remote should flicker (Fig. 16). If the ma-
chine c ontrol module is energized (control module Time
Out and Power LED’s are both illuminated) and a remote
transmitter button is pressed, the corresponding control
module LED should illuminate and the control module
RF activity LED should flicker.
If the control module is energized (control module Time
Out and Power LED’s are both illuminated), remote but-
ton functions are as follows:
Pressing the Engine Start button initiates a starting se-
quence to start the engine. This sequence (see Opera-
tor’s M anual) is necessary to prevent accidental engine
starting. After pressing the Engine Start button, the RH
Nozzle and LH Nozzle Rotate buttons are inactive for
five (5) seconds.
Pressing the Speed Increase (rabbit) button when the
engine is running causes the engine speed to increase.
Pressing the Speed Decrease (turtle) button when the
engine is running causes the engine speed to decrease.
Pressing the RH Nozzle Rotate button causes the blow-
er nozzle to rotate to the right.
Pressing the LH Nozzle Rotate button causes the blow-
er nozzle to rotate to the left.
Pressing the engine Stop button causes the engine to
stop running.
NOTE: Whentheenginestopbuttonontheremote
transmitter is pressed, there will be a one (1) second
delay before the engine stop LED on the control module
illuminates. Also, for approximately five (5) seconds af-
ter the stop button is pressed, the control module engine
stop LED will remain illuminated and no other remote
transmitter o perationscanbeperformed.
The remote transmitter is powered by three (3) AAA al-
kaline batteries. If the range of the transmitter has dimin-
ished or the transmitter LED does not flicker when a
button is pressed, the batteries should be replaced.
Remote Transmitter Battery Replacement
1. Remove six (6) screws that secure t he rear cover to
the remote transmitter.
2. Lift rear cover from remote transmitter.
3. Remove batteries from r emote transmitter and re-
place with three (3) new AAA alkaline batteries.
4. Place rear cover on remote transmitter and secure
with six (6) screws.
