SCM6/1 ELETTRONICA 5. Quick guide for installation and use This section provides a step-by-step description of equipment installation and configuration procedure. Follow these procedures closely upon first power-on and each time any change is made to general configuration, such as when a new transmission station is added or the equipment is replaced.
5.2 Modes of Operation The SCM6/1 can operate in different modes, depending on the combination of the position of the switches on the front panel. Switch REMOTE/LOCAL (5 figure 4-3) •...

“Local” mode (e.g. for maintenance) and if it’s set as enabled in the SCM6/1 configuraration. To modify the configuration of this setting on the SCM6/1, push the encoder when the cursor is on this item: the indication Enabl.

5.3.2 Mode Menu When the SCM6/1 is in local mode, this menu allows the user to select one out of three operating modes: EXPLOITATION The user can only read the parameters without changing them.

When switched ON, the transmitter is allowed to keep the InhBit Inhibit signal active for a time as long as the one configure in this field. The SCM6/1 will start checking the Power Good status only at the end of this interval or when the Inhibit signal is deactivated.
Page 21
5.3.5 Ack. menu The “Acknowledge” menu is useful for diagnostics pourpose, since it gives the status of the transmitters as they are seen by the SCM6/1. A “X” in this column indicates the presence of the ON signal, a “-” indicates its aInterlockence A “X”...
5.3.7 GSet menu The General Settings menu is used to set the date and time of the SCM6/1, that is used only for diagnostic purpouses (see Alarm menu). To set the current date and time, enter in the menu screen pushing the encoder on the indication GSet in the navigation bar.

• the current configuration of the system (enabled/disabled, Priority) coincides with the configuration stored in memory using the “CONFIGURATION” mode. The SCM6/1 includes a protected button to force the system in Nominal mode. User Manual / 40 Rev. 2.0 - 29/11/22...
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: •...
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.

An example of the set of TCs and TSs exchanged between the SCM6/1 and a transmitter Is given in figure 4-3.

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.

Steps are taken to avoid the recyclage delay to be inserted more than once consecutively for a given transmitter. The last delay used by the SCM6/1 is the “before” timer, configurable for each transmitter.

SCM6/1 ELETTRONICA 7.1.1 Supply of TCs and TSs An important point in the interconnection of different devices exchanging telecontrols and telesignalling is the way the related signals are supplied. Figure 5-2 gives a schematic overview of the different power sources for the signals involved in a complete N+1 system.

ELETTRONICA 7.1.2 Transmitter control boards The SCM6/1 includes one transmitter control board for each of the transmitters in the system. These boards are based on a Fujitsu MB90F543 microprocessor for the implementation of the I/O logic, they have 18 digital inputs and 26 digital outputs.

1-3, 2-4: The power supply for the TC for the frontal comes from the corresponding transmitter 3-5, 4-6: The power supply for the TC for the frontal is generated by the SCM6/1 (common voltage) On the right side of the three connectors of the flat cables that join the board to the relay board, there are six 4-pin strip lines.
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.
As for the audio grid, 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 RDS signal of the suInterlocktituted main transmitter to the reserve transmitter.
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)

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.

• 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.
