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.
7.1.1 Transmitter
Table 4. Transmitter Status LED Fault Identification
LED
Indication
Solid Green
Transmitter transmitting normally. OPERATION Mode.
Green Pulses
Transmitter ready for Start-up. STAND BY Mode.
Red – Slow Flashing
Battery level low.
Red – Fast Flashing
EEPROM module is not plugged in.
Red – Double Flashing
Transmitter cannot start up because a motion command is present (stuck
or broken switch).
Red – Solid
Transmitter failure.
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.
