7.0 Maintenance

The TM70 is designed for use in an industrial environment. However, we recommend you follow

the following instructions to extend the life of your remote control system.

• Use the shoulder harness or belt provided with the transmitter to prevent the transmitter

from falling.

• Do not clean the transmitter with solvents or pressurized water. Use a damp cloth or soft

brush.

• Regularly use and recharge the battery.

• Check that the STOP pushbutton is working on a daily basis.

• Disconnect the receiver cables if soldering/welding work is going to be done on the crane

or controlled machinery.

• Periodically check the condition of the transmitter’s rubber seal. Change the seals if they

show signs of deterioration to ensure the unit remains watertight.

• Keep battery contacts clean.

7.1 Fault Identification

Both the transmitter and receiver have status monitoring LEDs that help to identify failures. The

most common signals are contained in the tables below.

7.1.2 Receiver

In OPERATION mode the five LED’s must be lit as previously described. If this condition exists,

press the transmitter motion pushbuttons and observe the response of the output relays.

• If the response is normal, the problem is not related to the remote control equipment and

the installation must be evaluated.

• If any of the relays are not activated, the problem is associated with the remote control

equipment. Observe the status of the LED’s and reference Table 5 to determine the

problem source.
