1.1 DESCRIPTION
The Amplifier Control (AC) module is the equipment that allows to monitor and manage from a single location
a modular transmitter, composed by several combined amplifier modules (AM). The AC continuously monitors
the status of the AMs and highlights any anomaly, it monitors the powers in antenna (forward and reflected)
and the unbalancing, if any, showing all of the parameters on the display and through the status LEDs. It is
possible to power supply the fans of the rack directly by the AC, which constantly monitors their operation,
thus protecting the AMs and the other components in the rack in case of failure. Even the exciter(s) can be
powered directly by the AC, so that it can be switched on or off along with the amplification stage.
The human-machine interface (HMI), intuitive and user-friendly - most of all thanks to the large graphic
display which covers the most of the front panel and to the six status LEDs -, the noise-immune RS485
connection with the AMs, the possibility to connect a series of switches to an Interlock input and the remote
control option make the AC a reliable, as well as easy to use, device to be used in low and high-power, FM
and TV, analogue and digital, combined and separated transmitters.
In most cases the AC is already installed into the transmitter, wired and calibrated, so that the user can use it
without having to worry about technical details. Anyway, Section 2 of this manual covers the main information
about installation and external connections. For additional technical information, contact the Customer Service
of Elettronika S.r.l. or the local distributor. Section 3 describes the operation of the AC and everything the
user can do with it. Read this section carefully before using the device.
