Alarm Window
The alarm window may contain three icons indicating anomalies in the
operation of the transmitter.
The first icon on the left represents the status of the Interlock. If there is no
Interlock alarm, thus the switches chain is closed, the icon is a closed
door. In case of Interlock alarm, it is a blinking open door. In case the
Interlock is disabled, the icon will not be displayed at all.
The second icon, in the middle, refers to the status of the transmitter fans
and can be a still fan (fans aren't rotating) or a moving one (fans are rotating).
It is important to note that this icon represents the status of the FANS
CONTROL contact located on the rear panel, which indicates the actual
work (rotation) of the fans rather than the fact that they are powered or
not. In other words, it is possible that the fans are powered but, for some
anomaly, are not working correctly. In this case the icon is a still fan blinking.
The third icon, on the right, indicates a generic alarm. It is not displayed if
the AC is not detecting any malfunctioning condition, while it is displayed
as a bell in case of any alarm condition. If the alarm condition ends, the bell
blinks to indicate that something happened previously. It stops blinking if
the alarms list (Log) is accessed to check the occurred events.
Date and time window
The AC is provided with an internal clock with a backup battery placed
on the display board. The date is used to associate each event in the log to
the exact time at which it occurred. The time can be set from the Settings
menu. The AC synchronizes all of the AMs so that all of them display the
same time.
hard to read, the contrast can be adjusted by acting with a small screwdriver into the hole on the frontal panel
marked with the symbol.
The main screen is similar to the one in figure below. It may change depending on the transmitter, for instance
depending on the number of AMs and unbalancing.
