5. Initial Configuration
After installing the radome assembly and the ACU, the VS61 antenna must be configured
with some parameters to ensure correct operation of the antenna. This section concerns
‘How to configure the antenna for the first time’. If the initial configuration is incorrect, it may
have a detrimental effect on the antenna’s operation.
5.1
Supply AC Power
During the initial power-up sequence, the ACU provides DC current (48 VDC) via the
receive (RX) L-band cable. The ACU has a built-in short-circuit protection to ensure that
there is no short circuit between the center conductor of the L-Band RX cable and the
shield or other metallic surfaces.
5.1.1 ACU Operation Procedures
The KA-160 ACU is initialized as shown in Figure 5-1 or Figure 5-2 of the ship’s gyro
types when the ACU power is on.
