4.0 Using the System
4.1 General Instructions
Use the following instructions to properly operate the equipment:
7. Attach the harness to the transmitter to prevent the equipment from
falling.
8. Make sure of the transmitter you are going to use. Verify that the machine
you want to operate matches the transmitter identification label—the label
allows the operator to identify the machine before starting the equipment.
9. Install a fully charged battery into the transmitter.
10. Make sure all command controls are in the neutral position. All the
command controls associated with active motions must be in the neutral
position (inactive) to enable the transmitter.
11. Turn the ON/OFF key ON (clockwise) to enable the transmitter.
12. Pull out the Stop Button. The LED should pulse green telling you the
transmitter is ready for use.
Note: If you find that the Stop Button is already pulled out, you must push it in and
then pull it out again. This sequence permits proper operation of the Stop
circuit. If the unit has experienced a time-out auto-disconnect, it is not
necessary to repeat the Stop Button procedure; instead, push and hold the
START Button for one (1) second.
13. Press and hold the START Button. This activates the warning/start
alarm if one is installed on the crane/machine and indicates to you the
receiver is under your control.
14. The green LED should light indicating that the transmitter is now
transmitting. Now when any of the transmitter command pushbuttons are
pressed, the corresponding motion is activated.
15. Press the Stop Button or turn the ON/OFF Key counter clockwise to
turn the transmitter OFF.
4.2 Battery Level Monitor
TM70 transmitters are equipped with a battery-level monitoring circuit. When the charge
level drops below a pre-defined limit, the transmitter LED flashes red indicating the
transmitter will switch OFF and be disabled in five (5) minutes. When the transmitter is
disabled, the machine’s main contactor is de-energized. If the Stop Button is pushed
during this 5-minute warning period, the transmitter will not start again until a
fresh battery is installed.
For safety sake, the load must be located to a safe position and area
during the 5-minute warning prior to Low Battery automatic shutdown.
Beware: If the STOP Button is pushed during this warning time,
you cannot use the transmitter again until a fresh battery is
installed.
