2.1 Principio di funzionamento Operational principle
The KTC system is used to activate commands by remote control (to start up equipment for example) and to
turn on signals ( i.e.: telemetry ...).
The KTC consists in a transmitting unit and a receiving unit.
The transmitting unit communicates with the receiving unit by means of a coded radio message which contains
data and address information. The receiving unit can only decode messages sent by the transmitting unit
belonging to the same kit (i.e.: with the same address). This ensures that signals or unwanted commands
cannot be activated. In the event of: interference; an incorrect or interrupted radio transmission, the receiving
unit stops the system autonomously (passive emergency function).
Risk analysis of the equipment or system which uses a KTC , has to take into account that the
radio link may be interrupted, due to electromagnetic disturbance or interference. This will
cause interruption of the KTC system functionality and will require a new start-up sequence.
The transmitting unit is installed where the commands are activated (INPUT) by means of actuators
(pushbutton, relays, output PLC ...). The receiving unit is installed where the commands or signals (OUTPUTS)
are controlled (relays, lights, lamps etc..).
The KTC is programmed for use at a certain radio frequency.
The frequencies used fall within the band of frequencies established by European regulations at the time the
KTC was put onto the market. There are two versions of the KTC: one uses the band of frequencies 433.050 -
434.790 MHz, the other uses the band 869.7 - 870 MHz.
Look at the attached "Limitations & Authorisations" to see the limits imposed in the country in which the
KTC is being used.
Should it be necessary to install the KTC near other radio equipment, the radio frequencies used by the two
radios must be different (for frequency setting see Service Manual).
The following minimum documentation is supplied with each radio remote control:
- installation and operation manual
- service manual
- a CE conformity declaration
- a guarantee certificate
- the radio remote control technical data sheet
- the enclosed "Limitations & Authorisations".
Make sure that the following documents have been supplied: if they are not, request them from Autec.
Please specify the radio remote control serial number.
