Wireless Control Module (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 wireless control module is a solid state electrical de-
vice that receives signal inputs from the remote trans-
mitter and uses those inputs to control machine
electrical operation. The control module is attached to
the f rame next to the battery (Fig. 19).
Inputs from the ignition switch and the remote transmit-
ter are monitored by the control module. Output to the
magneto relay, fuel r elay, power relay, engine starter
motor solenoid, engine throttle control module and
nozzle rotation motor are controlled based on the inputs
received by the control module.
To start blower operation, rotation of the ignition switch
to the START position is used to turn on or “wake up” the
control module. The control module Time Out and Pow-
er LED’s should both be illuminated during blower op-
eration (Fig. 20).
When a remote transmitter button is pressed, the corre-
sponding control module LED should illuminate and the
control module RF activity LED should flicker (Fig. 20).
NOTE: Because of the normal RF activity in the envi-
ronment, the control module RF activity LED may flicker
or be illuminated at any time during machine operation.
Machine operation will only be controlled by the remote
transmitter that is recognized by the control module.
NOTE: Whentheenginestopbuttonontheremote
transmitter is pressed, there will be a one (1) second
delay before the control module engine stop LED illumi-
nates. Also, the control module engine stop LED will re-
main illuminated and no other remote transmitter
operations can be performed for about five (5) seconds.
The control module includes a t ime--out feature to allow
machine operation for a time period after the last control
input (e.g. key switch turned o ff or remote transmitter
button pressed). I f no inputs are provided to the control
module during this time period, the control module will
shut off all machine electrical power including turning off
the engine, if running. When the engine is turned off with
either the key switch or the remote transmitter, the con-
trol module Time Out and Power LED’s will both be illu-
minated for this time period. Refer to your Operator’s
Manual for additional details on the t ime--out feature.
The control module does not connect to an external
computer or hand held device, can not be re--pro-
grammed and does not record any fault data. The ma-
chine wire harness does include a communication port
with loopback connector that should remain connected.
Because of the solid state circuitry built into the control
module, there is no reliable method to test it. The module

electrical test device, such as a digital multimeter.
IMPORTANT: Before performing any welding on the
machine, disconnect the negative battery cable
from the battery and the wire harness connector
from the wireless control module to prevent dam-
age to the electrical system.
