RC2000 Cable Preparation ACU Installation Troubleshooting/Alarm codes Patriot 1.
Installation Instructions I. Needed equipment: Multimeter, small flathead screwdriver, large phillips screwdriver, test/extra potentiometer (Contelec PD2205h, 5K, 5 turn), allen wrench (to center potentiometer), heat gun for heat shrink, cable jacket strippers (Greenlee p/n 45109), wire cutter, wire stripper (14-22 AWG), crimp connector tool. II. Supplies: Spare fuses (5A slow blow), Heat shrink (Drain wire, Actuator cabling, Pol Pot cable.
A. Connect AZ motor: Az motor Drive: J2 on RC2000: AZ Drive 2; J2:6; black 14 AWG AZ Drive 1; J2:4; red 14 AWG Azimuth acuator/DC motor Negative terminals Positive terminal B. Connect AZ sensor: AZ sensor: J1 on RC2000 AZ sensor Pulse; J1:7 AZ sensor Ground; J1:6 AZ sensor Shield; J1:6 shields AZ position sense/reed switch Green Black No connect Moving the antenna by pressing the AZ/CCW will always result in a decreasing count value.
IV. 24V Rotating Feed (RC2KPOL): Feed type: TXFD-KLMOTGAM AKU (Single Port) Verify potentiometer is at center position or damage may result to pot. (Refer to Ch. 3, Section 3.3. in user manual) Note: Caution Do not attempt to drive the AZ, EL or POL with a external power supply while the controller is connected to the antenna. This will result in damage to the controller’s internal driver circuitry. A.
V. Set AZ/EL Limits Caution: In LIMITS mode the user has unrestricted movement of the antenna, there are no software azimuth or elevation limits, and antenna jammed sensing does not take place. When moving the antenna in LIMITS mode, an assistant should be stationed at the antenna to ensure that the antenna does not move past a physical limit. Note also that the CW and CCW polarization keys are active. A. Setting AZ/EL Limits Enter into the AZ/EL LIMITS menu. 1.
3. Press ENTER once. The screen now reads: ‘Caution-Unrestricted POL movement, See manual! Enter to Continue.’ 4. Press Enter; The count value next to PL: should be a 3 digit number. When jogging CCW the count value should increase. CW decreases counts. 5. Skew pol all the way one direction, as far as the feed can physically go, without damaging the feed or the potentiometer, using the 1(POL CCW) and 3 (POL CW) keys. Press the 5 key and this will set the first limit. 6.
internal list, the user is presented with a longitude value also from the controller’s internal list. 3. Screen reads: ‘Select Band. 0 – C, 1 – K, 2-C&K. Enter’ Select 1 for KU band. 4. The next screen prompts the user to specify the Pol CW/CCW position. Skew the POL to the Horizontal position and press the H/7 key. The screen will briefly say H POL set. Skew the POL to the Vertical position and press the V key and the menu will display ‘DATA ACCEPTED’. Repeat Steps 1-4 to program in additional satellites.
TROUBLESHOOTING/ALARM CODES The alarm system monitors important system parameters and flashes a message on the bottom line of the LCD display if an error is found. The parameters monitored include the condition of the lithium battery, status of the azimuth and elevation antenna drive systems, and the values of certain variables. Some error codes have priority over others. Alarm conditions are sampled sequentially, with the highest priority sampled first.
ANT AZIM, ANT ELEV, ANT POL These alarm messages indicate that an error has been detected for the axis referenced in the alarm message. When one of these alarms is detected, the axis is disabled. Go to RESET mode (section 4.5) to view the actual fault condition which was detected and to clear the fault. A Reset mode JAMMED indication may mean that the drive breaker is open. This can occur if simultaneous movement is enabled, and the total current draw from both motors exceeds 8 amps.
COMM PORT This alarm indicates that the checksums associated with the CONFIG mode Remote Mode Enable, Comm Port Baud Rate, and Comm Port Address items indicate that at least one of these items is invalid. See section 4.10.3. AZ/EL ANGLE DISPLAY This alarm indicates that the CONFIG mode items associated with the display of azimuth and elevation position in an angle format have been corrupted. Please see section 4.10.6.
when approaching the satellite from the azimuth clockwise direction and another when approaching the satellite from the azimuth counter-clockwise direction. To test for this, move the antenna well past the satellite in the azimuth clockwise direction and then manually move the antenna counter-clockwise at slow speed until the peak is reached. Repeat the procedure approaching the satellite from the opposite direction. The difference in azimuth position between the 2 peaks is the mechanical hysteresis.
AutoPol function and the controller does not toggle the polarization position as the H and V keys are depressed in MANUAL mode, the polarization positions have probably been programmed at the same value. Other AutoPol problems result from not having a ground wire connected between the satellite receiver and the controller. Please refer to figures 3.2 and 3.3. The AutoPol system should not be enabled when the controller is used with feeds that receive both polarizations simultaneously.
Revision Page 1/24 Rough draft_B.P 1/25 Revised some spelling. Added in AZ/EL motor and sensor connection per the Patriot 1.8 Navigator schematic. Added in troubleshooting tips. _B.P 1/26 Added in troubleshooting tips about controller not going back to sat. Change Equipment needed from Big Phillips to Large Phillips screwdriver. Changed Pol limits section from 2 port feed to a 1 port feed. I added the word internal in the troubleshooting tips in the paragraph about not using an external battery.
