2DESCRIPTION AND OPERATION OF THE SYSTEM COMPONENTS
2.1 Control switchboard of antenna heating system
CSAHS is a painted metal cabinet. Figure 2 describes a general view of CSAHS
with an integrated repeater.
Figure 2 –CSAHS with an integrated repeater
CSAHS is mounted on the wall through the mounting holes (Figure 2, position 9).
Three LED light indicators (Figure 2, position 1) are located on the front panel
displaying CSAHS operation status (on/off), main and standby power. Once the power is
supplied, corresponding power LED is lighting up (green), when there is no power –LED
is not lighting. «ON» LED is lighting (green) together with one of the power LEDs.
Repeater is installed into CSAHS front panel (Figure 2, position 2). Use a key to
open the cabinet (Figure 2, position 3). Nameplates of the System (Figure 2, position 7)
and CSAHS (Figure 2, position 8) are attached to the side panel.
Cable glands SKINTOP MS-M 25x1.5 ensure main and standby power
connection to CSAHS (Figure 2, position 4). Use cable glands to connect KP: SKINTOP
MS-M 16x1.5 (Figure 2, position 5) for CAN bus connection, and
SKINTOP MS-M 25x1.5 (Figure 2, position 6) to connect AHU power supply.
2.2 Antenna heating unit
AHU is an RF transparent thermal insulating dome with TH and temperature
sensors installed inside it. Figure 3 describes a general view of AHU (for example,
AHU-1).

Version 0.1.1 10
Antenna heating system AHS-1022
Dependingon size(seeTable 2 and FiguresА.1–А.3) and quantityofTH, AHU may
have three types:
‒AHU-1 –small, two THs;
‒AHU-2 –medium, four THs;
‒AHU-3 –large, four THs.
From two to four THs ensure heating of each antenna (Figure 3, position 2). AHU
maybe delivered with a dome (Figure3, position 5), and without it. Temperature sensors are
located near THs to monitor current AHU temperature (Figure 3, position 4).
Use data connectors (Figure 3, position 3) and power input connectors (Figure 3,
position 1) to connect KP.
If AHU is applied together with a dome, connect AHU through cable glands at the
bottom of the dome (Figure 3, position 6), and mount it –using mounting studs (Figure 3,
position 7).

2.3.1 Description
Repeater is manufactured in painted metal casing; a port to connect power cable
(Figure 5, position 3), and interface RS-422 serial ports to connect data cables (Figure 5,
position 1 and 2) are located on the rear panel under the protective cover. A USB port to
connect data storage device (to update AHU and repeater software) (Figure 5, position 4)
is on the right side panel. AHU software update is available only for manufacturer’s
representatives.

2.3.2 Repeater’s software
Getting started
Once repeater is switched on, AHU initialization and operation test occur. If all
connected AHUs are on the network and operate correctly, the display will take the main
screen view, see Figure 8.
If an error occurs in AHU operation, the main screen will display «Тревога» on
the red flashing background, and the line of faulty AHU will be highlighted with
red (Figure 9, а), or «Предупреждение» on the yellow flashing background, and yellow
line of faulty AHU.
If repeater is switched on at the moment of main or standby power failure, the
main screen will display «Предупреждение» on yellow background (Figure 9, b).
