How to Check AEU
■3－1：Check Extension and Retraction
We strongly recommend you to pre-assemble AEU and check it working before
installation of VERSA Beam.
You will use KA1 controller to confirm AEUs working properly to extend and retract
elements.
We are very careful of handling and packing, however AEU may get damage during
transportation. Be sure to confirm elements come out of and get in AEU. This
procedure is a must if you don
’
t want to do unnecessary hard work after installation
on the tower.
