KA BAND OUTDOOR TWT AMPLIFIER
•
The optional Remote Control Unit is connected to a single-phase 100-240 +/- 10%
V
AC
47-63 Hz prime power source.
•
There is at least 4 inches of clearance at the front and rear of the amplifier and 2
inches of clearance of the bottom of the amplifier. (The fan and exhaust areas are
not blocked.)
3.7 Power-On Sequence
Initial power on should not be attempted until all pre-power procedures (Section 3.5) have been
successfully completed.
3.7.1 Initial Check, High Voltage OFF
Each time the Ka-Band TWTA power is switched on, the microprocessor controller performs a
series of self-tests to ensure that it has the ability to control and monitor the amplfiier. Once the
initial tests (POST) are successfully completed, the amplifier initiates a heater time delay cycle of
about three minutes to allow the TWT (traveling wave tube) heater to warm up. Proceed as
follows:
1. Temporarily disconnect the remote/CIF connector at J6 (if used).
2. Turn on the prime power distribution system so that AC power is applied at J1.
3. Verify that the following sequence occurs after AC power is applied:
4. PWR ON LED lights.
5. The cooling fan comes on.
NOTE: The fan will come on initially during SELF-TEST, but may
remain Off until the TWT collector temperature increases above a
specific threshold.
6. All front panel LEDs light momentarily
7. After three minutes, the STBY LED lights.
If a fault occurs during heater warm up, the FLT LED lights. If this occurs, press RESET. If RESET
fails to clear the fault, disconnect AC power from the unit and refer to Chapter 5.
NOTE: If the system includes a Remote Control Unit skip to 3.6.1.2;
otherwise, refer to 3.6.1.1.
