4 Installation 4.1 Introduction. The procedures for installing the radio units / transceiver are described in table 4.1 below. It is recommended that these procedures are completed in the order shown. Procedure 1 Initial inspection 2 Install equipment into 19” sub racks (equipment cabinet) 3 Connect chassis stud to system earth or cabinet Reference 4.2 4.3 Figure 3.2-1 (TX) Figure 3.4-1 (RX) Figure 3.
4.3 Installation into equipment cabinet The units may be installed into a standard 19” subrack with a height of 3U. The total subrack is divided into 84 TE units. The transmitter occupies 28 TE, the PSU occupies 14TE and the receiver unit occupies 14TE. For a transceiver this leaves a free space of 28TE available for other equipment. Figure 4.3-1 shows some examples for installation into 19” subrack.

The connection can be done via a distribution panel or by making a special with RJ45 connectors in each end. The cables used should be of the same quality as a CAT5E network cable and the screen should be connected in the plugs.
4.7.4 Receiver, main / backup configuration By connecting the alarm output from one (main) receiver to the select input on a backup unit, it is possible to perform automatic switching between them. In this way, if a main transmitter detects an internal failure, it can be set up to enter into standby mode and stop reception of signals. The alarm signal will also signal to a backup unit to take over the receive function. Figure 4.

6.2 Receiver error conditions Display Description Press Use from the main display to bring up the available menus. to navigate to the Bite system menu and select by pressing Select Alarms and press The displays shows module(s) where the BITE system has detected failures. To view more details about the failure, select module. Table 6.
RX alarm Power module High Temperature Temperature reading is above +85°C High Current Current consumption is above 500 mA 12V 5V 3.3V Action: Replace RX unit (LRU) Power module (LRM). Probable cause: Failure on one or more components on the power module. Action: Replace RX unit (LRU) Power module, Main module or RF module (LRM). Action: Replace RX unit (LRU) Power module, Main module or RF module (LRM) Cause: Excessive current consumption in one or more modules.
