toggle switch.
Paddle Levers - Standard GL paddle levers provide
stepless proportional speed control without detents for
up to 7 motions.
Option Toggle Switch - The connected function will be
activated when the toggle switch is moved to the ON
position. The function will stop when the switch is
moved to the OFF position.

allows the operator to control multiple cranes/machines
from a single transmitter, or multiple crane/machine
motions from a single joystick or paddle lever. The

GR TRANSMITTER
The GR transmitter is a "belly box" design. The
operator uses joysticks or paddle levers to control
crane/machine motions. Standard GR joysticks and
paddle levers have proportional speed control without
detents. Optional joysticks provide up to five speeds
with detents. The GR joystick model can combine up to
three dual axis joysticks for up to six motion control.
The GR paddle lever model can accommodate up to
seven single axis paddle levers for up to seven motion
control.
The GR also offers a Selector toggle switch to control
up to nine crane/machine motions for
independent/combined control.
GR transmitter components are shown below.
GR Transmitter Functions
Start/Horn Pushbutton - This pushbutton activates the
mainline contactor and sounds the horn (if provided). If
the mainline contactor is already on, pushing this
button will only sound the horn.
E-Stop Pushbutton - Press the E-Stop pushbutton to
place the receiver in the Safe mode. Pull this
pushbutton out to disengage the E-Stop. The
transmitter will then control crane/machine motions.
IMPORTANT: The E-Stop pushbutton is for emergency
stops only. DO NOT use it as an OFF switch. Use the
key switch to turn the transmitter on and off.
Power LED - The GR Power LED flashes once when
the transmitter is turned on. The transmitter initiates a
self-test to check the software. When the transmitter
passes the self-test, the light changes to flashing
green. It continues to flash green until the transmitter is
turned off.
Key Switch - The key switch turns the transmitter on
and off. The switch will only turn with the key cap fully
inserted. The switch must be in the OFF position for the
key to be removed.
