  • Page 24 ELETTRONICA If the user pushes the “Nominal” button, the management software first asks for confirmation on the status bar. Upon confirmation, the SCM6/1 checks whether the actual status of the transmission system coincides with the one stored in memory as “nominal”, and then it performs the necessary steps to go back to the nominal status, that is: •...

  • Page 25: Operation

    When a transmitter has to be switched off by the automatism implemented by the SCM6/1 to perform a permutation, the TC Off is not sent, and only the Interlock is opened. This behaviour is intended to avoid the need for the pre-heating cycle.

    A fault event detected by the SCM6/1 will thus be treated differently depending on the status of the system. The basic aim of the SCM6/1 is to cyclically check the RF Power of the transmitters and to suInterlocktitute a faulty principal transmitter using the reserve transmitter.

    This device is basically constituted by a series of switches that are controlled by the SCM6/1. In case of changeover the switches are configured to route the audio signal of the suInterlocktituted main transmitter to the reserve transmitter. A panel of LEDs indicates the channel that is fed to TXr.

    SCM6/1 ELETTRONICA 8. Maintenance 8.1 Preventive Maintenance The components of the SCM6/1 that require suInterlocktitution as a means of preventive maintenance are the following: • 3 years • Electrolitic capacitors in the switching power suppy 5 years • Battery of the real time clock (BATT1 on the panel board)
  • Page 44 Remove the top cover of the SCM6/1 • Remove the screws that fasten the front panel of the SCM6/1 to the rest of the box and lower the panel to leave sufficient room to remove the card. Remove the metal bar that secure the control cards set.
  • Page 45 • Wait for the system to boot and check on the display the correctness of all the telesignals generated by the devices connected to the SCM6/1. • If everything is correct, put the transmitter in remote mode and configure the SCM6/1 in auto mode if required.
