Pins 1 and 2 are outputs on which the relay control voltage is made available (12V
or 24V DC).
Connected to pins 3 and 4 are the relay limit switches, two contacts which alternately
close towards the ground when the relay is in the normal position (TX1 connected
to antenna, pin 3 closed to ground) or switched (TX2 connected to antenna, pin
4 closed to ground).
Pins 6 and 7 are the commands which cause the coaxial relay to switch from
the normal position (Off) to the switched position (On) and vice versa; the type
of command depends on the coaxial relay used, as well as the connecting cable
between the SCM and the coaxial relay.
One of the possible positions of the control mode selection jumper makes available
on pin 8 the common contact of a switch, of which pin 6 is the normally open (NO)
contact and pin 7 is the normally closed (NC) contact.
Pin 9 is an open contact until switching begins, and is closed to ground when the
relay has reached the new position.

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.
Once the desired configuration has been set up, no more settings are required
for normal operation; at each power-up (even after an accidental shutdown),
the equipment defaults to the parameters set during the initial configuration
procedure.
The topics covered in this section are discussed at greater length in the next
sections, with detailed descriptions of all hardware and firmware features and
capabilities. Please see the relevant sections for additional details.
IMPORTANT: When configuring and testing the transmitter in which the equipment
is integrated, be sure to have the Final Test Table supplied with the equipment ready
at hand throughout the whole procedure; the Final Test Table lists all operating
parameters as set and tested at the factory.
5.1 User Interface
The machine features an LCD with two lines by 16 characters that displays a set
of menus.
The status of the machine is indicated by four LEDs located on the front panel:
MANUAL, LOCAL, MAINS, ALARM and seven LED for synoptical signalling.
The interaction between the user and the exciter control software is performed
using the encoder.
The operations that you can perform on the encoder are::

• Rotation: moves the cursor shows on the display; if you turn the encoder to the
left (counter clockwise), the cursor moves downwards, if you turn it right the cursor
moves upwards; it also permits to increase or diminish the parameters (turning
the encoder left diminishes the parameter.
• Pushing: push the button once when the cursor is on the name of a menu
to enter in that menu, push it when the corsor is on the name of a parameter to
enter in modification mode (the cursor starts blinking); after the modification of a
parameter, push the button to save the new value.
After having modified the value of a parameter, the cursor goes on blinking for
approximately 15 seconds, waiting for confirmation from the user. If the user
doesn’t confirm the new value (i.e., the button is not pressed), the parameter has
not saved and remains on the selected parameter.
The first pressure of the ENCODER when the display is light out, or its rotation,
serves in order to activate the retroillumination if disabled..

The main screen shows information regards the status of TX and the number of
automatic retry, moreover is present an hourglass that indicates:
1. Start time presence, if is the only icon present;icon present;
2. Exchange time presence, if the icon is combined withicon is combined with icon.
The icon identifies a temporary suspension of the exchange automatism andicon identifies a temporary suspension of the exchange automatism and
appears when:
1. The SCM is in ALARM status.
2. One TX is in LOCAL condition.
3. The total number of Retry is 0.
4. The number of makes Retry is the same to the number of total Retry.
