Removal and replacement of ADU modules 9.5 Removal and replacement of ADU modules 9.5.1 Overview All replacement of modules must be carried out by a Thrane & Thrane A/S service partner. The figure below shows the modules and their position. Some modules are equipped with LEDs for status information and troubleshooting. For instructions on how to open and remove the service hatch see Opening and removing the service hatch on page 3-22. Figure 9-9: ADU modules and motor stop switch 9-12 Chapter 9: Service & maintenance 98-133966-E2
1. GPS module. This module is positioned near the service switch at the bottom of the pedestal. It converts the GPS satellite signals into current position data. 2. VSAT Interface Module (VIM). The purpose of the VIM is to interface between the ADU coaxial cable carrying several signals (DC, modem, RX IF, L-band TX) and the cable to the LNB/BUC, and the PCM. The VIM takes the received L-band transponder signal from the LNB and converts it to a lower frequency and allows the whole L-band transmitter band to be routed to the BUC. For tracking purpose the VIM has a DVB-S/S2 demodulator for tracking at the TV-satellites. For narrow band signal or non-DVB tracking the VIM also has a power detector as signal strength indicator. The VIM also has PSU for the external LNB and BUC. The VIM consists of the following blocks: • Power supply block for on board circuits, supply to PCM board and regulated external output to LNB (with band switching) and BUC. • DVB-S/S2 tracking receiver with tuner and demodulator including wide band signal detector and narrow band channel detector. • LNB Receive signal down converter with mixer and PLL. • Cable attenuator section to control the output power variation to the BUC. • FPGA section to control the functions of the VIM including DVB transport stream decoding. • Filters for splitting and combining the DC, modem, received down converted IF from the LNB and the transmit signal to the BUC. 3. DC-Motor Driver Module for cross elevation (DDM). The DDM shall - based on inputs from the PCM - control the torque delivered by the brush-less DC-motors (BLDCM), used to control the position of the parabolic reflector. The DDM board is: • Communication slave of the ADU Serial-Bus (S-Bus) connecting the DC-motor Driver Modules (DDM), the Polarization Motor Module (PMM), the Inertial Sensor Module (ISM) and the Pedestal Control Module (PCM). • Connection to the BLDCM, and delivering the required phase current to the motor. • Decoding the HALL-sensor input from the Zero Reference Module (ZRM).
