Maintenance Related Guidelines
Signs and the Central Control Units (CCUs) are made of components that normally do not require
maintenance. During the installation phase of the system Aesys recommends that the mounting hardware
used for the support stirrups include properly fitting washers that will not accidentally loosen and that the
housing where the sign is located has enough ventilation to avoid the excessive accumulation of heat (for
auto-heating solar light radiation heating).
Periodically verify the state of the stirrups and the tightness of the mounting screws, especially for the
parts exposed to direct user contact.
Signs do not produce dangerous voltages internally and use voltages that are less than the vehicle’s
power supply voltages. In case of a damaged connector or connection cable or of accidental contact with
external parts (the housing), the voltage is short-circuited to ground causing protection hazards.
We recommend that the user contact Aesys personnel if any anomalies with the display (sign) occur.
Aesys cannot be responsible in the case of display system intervention by unauthorized personnel.
In the case of substitution of the internal circuit boards or spare parts, we recommend that the user refer
to the electrical diagrams that are included later in this maintenance manual.
