2.4 Operation
2.4.1 Installing and Operating the 2000-218 LNB Power Supply
1. Connect an RF signal to RF connector, J2 (Figure 2.2).
2. Connect RF+DC connector, J1, to the external equipment (Figure 2.2).
3. To insert +18VDC on the RF signal insert a 1 amp fuse (provided) in fuse holder, F1 (Figure 2.2).
4. To insert a 10MHz reference signal on the RF signal connect a 10MHz source to the REF IN, J3 (Figure
2.2).
5. Connect 90- 260 VAC, 47 - 63 Hz to AC on the back panel (Figure 2.2).
6. Be sure DS2 (green, DC Power) is on (Figure 2.3).
7. If fuse, F1, is inserted check that LNB Power LED, DS1, is on (Figure 2.2)
8. AC FUSE - The AC fuse is a 5 mm X 20 mm, 2 amp slow blow (Type T) and is inserted in the far slot
in the drawer below the AC input as shown in Figure 2.4. There is a spare fuse in the near slot. If a fuse
continues to open, the power supply is most likely defective.
