Assembling Junction Box ■ For testing purpose you don’t have to assemble completely. After connection make cables coming out of the box through holes. See［Diagram5、Figure10、Figure11-1、11-2］ ＊NOTE ・You don’t have to assemble Junction Box completely for testing purpose. You may have it with no cover without any trouble. ・We recommend to build Junction Box in order not to hurt Junction Board with tools. -
Page 17: ９． Procedure To Make Sure Your Aeus Working Properly
How to Check AEU Working Properly ■Please operate AEU using a controller AFTER the connection is done, connect AC Adaptor with controller. ＊Please follow the procedure#1 to #4 described here to check AEU. See［Figure12］ Make all the connection like AC adaptor with outlet and KA1 controller. You will see controller POWER ON, and then [Model Number, Software Ver., ROM Ver. - Page 18 ＊Why this happens During transportation antenna element might have come out a little because of vibration or shock. Unless all the elements are at HOME position, you cannot test VERSA antenna properly. Be sure to take a step described above to see as in Figure14.
- Page 19 Press ③DOWN button to extend elements. You can get about 9mm extension by one press. Continue pressing ③DOWN several times. After confirming elements move, and then press ③UP button several times until elements are fully retracted. When elements are fully retracted, they are stop retracting further. Now elements are at HOME position.
- Page 20 ＊HOME operation and HOME sensor After HOME operation, AEU numbers will be shown on LCD display. This means all the elements are at HOME position. A few seconds later power will be turned down automatically. See the table below to make sure corresponding numbers with elements for each model.
