B.13.6 Reset to Factory Defaults
Reset to Defaults allows the user to reset all parameters (fault settings, etc.) to firmware
defaults. Settings not affected by this command are: Helix Avg. Over Current Fault, Helix Over
Voltage Fault, Helix Under Voltage Fault, Beam On Elapsed Time meter, and Heater Elapsed
Time Meter.
B.13.7 CHPA HVPS Test Mode
(This category will appear only during FAAM and unit in Standby.)
This test mode allows the power supply to be tested with a special test jig. In this mode, Helix
Under Voltage Fault, Helix Voltage Detected in Standby, and TWT Thermal Fault are masked in
the Transmit state. This test mode may only be selected from the Local panel while the CHPA is
in the Standby state. If the CHPA prime power is lost while HVPS TEST=YES, the CHPA will
power up with no Beam Select and HVPS TEST=NO.
Lines 3 and 4 will appear as follows:
H V P S T E S T M O D E
H V P S T E S T : N O
To select this test mode, press either arrow key to select YES on Line 4. In this test mode, any
meter may be selected. All other CHPA features and controls (aside from the STANDBY and
TRANSMIT button) will be inactive. If a fault occurs, the HVPS TEST will be turned off.
When Line 4 indicates YES, press the TRANSMIT button to turn the beam on. Provided no fault
occurs, Lines 1 and 2 will appear as follows (Lines 3 and 4 will display the selected meters):
L O C A L
5 : 2 7 A
B E A M O N S E Q U E N C E P S T
Once the Beam On Sequence is complete, Line 2 will display the following:
H I G H V O L T A G E O N P S T
To exit this test mode, return to the HVPS TEST MODE menu. Use the arrow keys to choose
NO. The display (Lines 3 and 4) will return to the following:
