Preliminary Procedures
To Perform Preliminary Procedures:
The preliminary procedure described below must be performed before replacing the
SLIP RING/ROTARY JOINT ASSEMBLY
:
1. Perform System Shut-Down of the vessel’s main power AC Voltage terminal outside the
RADOME
.
2. Open the
RADOME
hatch.
3. Switch off the
ADE
POWER
BOX
at the
ANTENNA
PEDESTAL
base (located inside the
RADOME
).
4. Manually rotate the
PEDESTAL
AXES
to gain convenient access to the serviced unit.
In the following procedures, be very careful when tightening and loosening the
screws with which the parts are assembled and attached to the system. Some
of these screws are delicate and can be damaged by excess force. When
using an Allen key make sure to insert the key all the way into the screw head
to avoid thread stripping.
WARNING!
The Utility Outlet is connected directly to the vessel’s AC voltage input
terminals (125 VAC / 250 VAC). Therefore, there still exists live voltage at the
Utility Outlet after disconnecting the power supply to the ADE using the Mains
Power On/Off Switch.
Only qualified and authorized personnel are allowed to carry out system
service/maintenance procedures.
