The UP and DOWN arrow keys allow to select one of the slave or the alarm list; the RET key is used to
confirm the selection.
By selecting one of the slaves, it is possible to see all the parameters of that amplifier module, that is voltages
and currents of the power supply, forward and reflected power, temperature and, for some amplifiers,
unbalancing powers. The UP and DOWN keys allow to scroll the local measures of all the slaves. The ESC
key is used to go back to the main menu.
By selecting the Alarm List, two pages listing the latest 20 alarms saved are shown. Each line in these pages
includes the progressive number of the alarm, starting with the most recent, the number of the module in which
the alarm occurred (the indication “AC” means that the alarm occurred in the Amplifier Control module), the
parameter in alarm and the date and time of the alarm. The saved alarm can be deleted by keeping simultane-
ously pressed the UP and DOWN keys. The ESC key is used to go back to the main menu.
In the main menu there is the Alarm Status Window:
displays the status of the INTERLOCK, in case of alarm this icon blinks and the buzzer rings.
The INTERLOCK signal is a control available to the user to manage an On/Off sensor.
When the relevant PIN is grounded, the Master board does not signal any alarm, as soon as the
PIN is left floating, an alarm is detected;
shows the status of the FANS: works normally;
in case of alarm this icon blinks and the buzzer rings;
this icon blinks in case of ALARM.
If one of the parameters of a Slave or any of the ones directly checked by the Master is alarmed, the
general alarm LED and the alarm icon blink until the Alarm List is checked to see the type of alarm
occurred.
Besides, if an alarm for any of the powers of the signals in antenna occurs, the relevant measure in the
Antenna window of the display and the relevant LED on the front panel of the Master module blink until the
measure decreases below the threshold level, determined by the nominal power of the amplifier.
If the slave modules are working and an INTERLOCK or FANS alarm occurs, aside from the indication
explained above, the amplifiers are switched off. This happens immediately after an INTERLOCK alarm, or
about 7 seconds after a FANS alarm is detected.
