Checklist:  Status LEDs  Events List / Error Log. Identify Defective Part  Replace Part  Verify Initialization and Run POST Test Theory of Operation: The Polarization Motor Module (PMM) controls the polarity angle of the antenna by aligning the polarization unit on the back of this dish at the correct angle to match the linear satellite signal from the vessels GPS location for optimum signal strength. On the SAILOR 800 and 900 VSAT antennas this will also ensure the transmit signal is correctly aligned to prevent interference with the services on the opposite polarity. The PMM drives a stepper motor on the back of the dish to rotate the polarization unit of the VSAT antennas or the LNB of the TV antenna, based on commands from the Pedestal Control Module (PCM) to optimise the polarity look angle of the system. The polarity angle is calculated using the GPS position of the vessel and the look angle to the desired satellite. Upon initialization the position of the VSAT polarization unit is calibrated using a reference point (magnet) on the polarization unit and a Hall Effect sensor installed on the Zero Reference Module (ZRM) on the polarization axis. Whereas the TV antenna drives the polarity stepper motor from end-stop to end-stop to verify the full range of motion and calibrate its position. Once calibrated the VSAT antennas use an encoder installed on the polarization unit to count the increments/decrements of the polarization drive and provides this feedback to the PCM as a reference, where as the TV antenna counts the steps of the polarization motor to calculate the angle of the LNB.

www.cobham.com/satcom Spare Part Instruction – SAILOR 100, 800 & 900A/B PMM Document No.: 97-138940-D Revision: D The PMM has two LEDs for status and troubleshooting, should there be a fault with the antenna the system will go into safe mode. The pedestal voltage will drop from 48VDC to 20VDC, causing the DDM service LED’s to illuminate red to prevent the antenna from being able to drive. If this was caused by a defective PMM its service LED would also be illuminated red. All power LED’s should remain green providing they are receiving voltage. Troubleshooting - Diagnostic LEDs on the ACU: The ACU has 3 LEDs: Power, Logon and Fail/Pass. Verify the status of the unit by referencing the LEDs. If any of the LEDs are not steady green or flashing green then further diagnostics will need to be undertaken, referencing the below table: If the Fail/Pass LED is illuminated any colour other than steady green then it means there is an issue with the system. Log into the ACU using your web browser and refer to the systems event log as detailed in the following sections of this document.
