Chapter 3 Self Test Flashcards
(015) 2. When the missile on alert, what reports does the MGS send to the LCC?
Status and fault reporting
(015) 1. What components does the MGS work with to initiate, guide, and conclude missile flight and payload deployment?
The operational ground program (OGP), operational flight program (OFP), flight controls, reentry system (RS), and reentry vehicle (RV)
(015) 2. What component in the MGS acts as a single electrical ground point for the missile?
The power distribution unit (PDU)
(015) 4. Which battery in the MGS provides the majority of the power after launch?
Flight batter or battery assembly
(015) 5. What MGS component sends electrical signals and power to the GSP?
Missile guidance set control (MGSC)
(015) 6. What MGS component provides a reference for missile guidance and navigation?
Gyro stabilized platform (GSP)
(016) 1. What action must a technician perform to energize the J4, J5, and J6 three-prong receptacles?
The control relay is energized by pressing the POWER ON and OFF switches on the power control panel.
(016) 2. What indications will occur if the MGSTS senses an excessive power condition?
The lamps provide a visual indicator while the aural alarm provides an audible alarm.
(016) 3. What are the two purposes of the programmable DC power supply?
To simulate the resistive loads caused by the MGS during self-test of the MGSTS programmable load modules which are incorporated within the power supply unit (PSU). Second, the power supply provides the required DC voltages for the MGS operation during certification.
(016) 4. In which partition is the majority of the MGSTS programs stored in the HDD?
The secure data media
(016) 5. Which of CTA modules provides the voltage to control activation of the MGS and SRAM test load relays?
Direct memory access/ umbilical/ simulator self-test module
(016) 6. Which MGSTS test-point panel component does the operator use to test the overcurrent limits of the power module?
Switches
(017) 1. When will the MGSTS self-test program allow progress to the next self-test module?
If the module passes, the system automatically progresses to the next self-test module.
(017) 2. How is the output of the PSU verified during the MGSTS MGS power supply test?
By manually measuring its output voltage and current at the test-point.
(017) 3. What checks are performed during the MGSTS MGS power safing test?
PSU overvoltage and overcurrent limit checks
(017) 4. What indication is displayed if the absolute value exceeds the overvoltage tolerance?
A failure message is displayed in the MGSTS session log window and the software automatically aborts testing.
(017) 5. During initial power-on checks, how is the power removed in an out-of-tolerance condition?
The output of the PSU is monitored internally and is shut down in the event of an out-of-tolerance condition. It can also be shut down by the EMERGENCY OFF switch on the power control panel.
(017) 6. During the ROM verification test, how is the data contained in the MCG ROM checked?
The ROM verification test reads the MGC ROM and compares what was read to the MGC master ROM image on the SDM.
(017) 7. The MGS battery test places the SRAM better in what mode?
Shipping and storage mode
(017) 8. What is the last test accomplished during the certification procedures before a MGS is ready for installation in the field?
Post certification
(017) 9. How will MGSTS respond if the technician selects the MGS certification option prior to running a self-test?
The software automatically prompts the operator (technician) to perform the self-test option first, and then continues with the MGS certification procedures.
(017) 10. If the post-certification self-test passed and a new MGS is to be certified,will another self-test be required if power was not removed from the MGSTS?
No. The post certification self-test is considered to be the precertification self-test by the software.
(018) 1. The GMATS was designed for what purpose?
To provide testing and troubleshooting of components used as operational support equipment (OSE) for the Minuteman weapon system.
(018) 2. What component allows for the transfer of operating power and stimuli between the UUT and the test station?
Interface test adapter (ITA)
