MAINTENANCE
Tecnord’s RC-DBX,RC-PCM,RC-NBM Radio Control Systems does not require any special maintenance. However, some precautions
are necessary in order to ensure that the equipment is both efficient and safe. Each radio control must be checked at least once a year.
The staff in charge of maintenance must check that the receiver is not powered on during the checks and the inspection inside the
transmitter.
Dust and other material from the working environment as well as dirt can deposit on the transmitter and receiver units. Remove it
so that the buttons, joysticks and actuators in general, including the emergency stop push button, are always clean and therefore in
good working order.
Each control unit has been designed so that all that the above causes the least amount of problems possible to the smooth
operation of the Radio Control. However, careful periodical maintenance by the user will certainly prolong its life span.
The inner inspection of the transmitter should be carried out only by trained staff in a dry and dump-free place. As well as removing
all traces of dirt and drying any condensation with warm air, the checking of the connections of the different wires and terminal boards
of interconnections, as well as the dean condition of the electrical contacts of all of the control actuators is also highly recommended.
WARNING!
In the event of the possible oxidation of the electrical contacts, never use any type of anti-oxidant spray or similar
product. Instead, contact your service center to immediately replace these parts. These problems can be caused by the
particular environmental conditions in which the radio control operates. Using chemical products on the actuators
could cause irreparable damage to the mechanical and electronic parts.
The duration and the capacity of the batteries depend on many elements such as the operating temperature, the charging and
discharging cycles, but basically on how often the radio control is used. It is highly recommended to always use the battery charge until
the “low battery” indication aactivates, and to replace it at least every 2 years.
Besides the regular checks on the interconnections and the firm tightening of the terminal boards for the output controls, it is
recommended to check that the seal of the transmitter unit cover is in good condition and that it is watertight. After 2/3 years of
operation, it is suggested to check the smooth operation of the electronic and electro-mechanical parts, their response to commands
and their drop out speed. Special layers of resin-based insulating paint and with anti-oxidant properties protect the electronic parts of
the Radio Control system; hence they do not require any maintenance. It is, however, necessary to check the various interconnections
between the different modules.
