Section Il. EQUIPMENT DESCRIPTION AND DATA

1-7. Equipment Characteristics, Features and Capabilities

a. The characteristics and features of the test set are:

(1) The ALT test set is portable and can be used when the environmental and power requirements are available(para 1-9).

(2) All operating controls are on the front panel. Cables and technical manual are stored inside top cover.

(3) Calibration is not required.

b. Capabilities. The test set will fault isolate the ALT receiver and electronic assembly to the major subassemblylevel.

Section Ill. PRINCIPLES OF OPERATION

1-10. General Information

The following paragraphs present an overall block diagram analysis of the test set. The analysis is divided into eightmajor areas which describe the circuitry within the test set involved in troubleshooting the ALT receiver or electronicassembly. To supplement the narrative description, a block diagram is provided for each functional area.

TM 11-6625-2638-30

1-11. Receiver Cage Test Functional Description (fig. 1-3)

a. Torque motor power (28 vdc) is supplied from the test set power supply through MOTOR PWR switch S19.Resolver outputs from the receiver are monitored from the SERVO jacks through SERVO switch S8.

b. The receiver high or low azimuth servo gain is selected by switching AZIMUTH GAIN switch S5 between-20 vdc for high gain and open for low gain.

c. When GIMBAL COMD switch S17 is in the CAGE position, the appropriate elevation and azimuth servo com-mands are selected from the circuit card assembly and applied to the receiver.

Figure 1-3. Receiver Cage Test Block Diagram.

1-5

TM 11-6625-2636-30

1-12. Receiver Scan Test Functional Description (fig. 1-4)

a. To initiate the scanning mode, a plus or minus 5 vdc is applied to the EXT AZIMUTH (J24) or EXT ELEV (J23)jacks. The plus or minus 5 vdc is applied to the receiver under test through the GIMBAL COMD switch S17 as theelevation and azimuth servo commands. The plus and minus 5 vdc is supplied by power supply and the polarity isselected by the RCVR CURRENT switch S20.

b. When the servo commands are given, the platform responds with an appropriate movement. The time requiredfor each platform excursion is timed by a stopwatch.

1-13. Receiver LED Test Functional Description (fig. 1-5)

The circuit card assembly provides elevation and azimuth servo commands to the receiver through GIMBAL COMDswitch S17. The circuit card assembly also provides to the receiver the LED PRF by the LED PRF switch S6, andthe MLO signal by the MLO switch S7. The receiver Σ AT signal is monitored at the Σ AT jack (J25) by the oscillo-scope.

1-14. Electronic Assembly Power Supply Test Functional Description (fig. 1-6)

The DVM/SCOPE switch (S3) takes the electronic assembly power supply voltages selected by ELEC VOLTAGEswitch S21 and routes them to the ELECT DVM jacks. The DVM indications are used to determine if the voltagesare within allowed tolerances.

Liberated Manuals -- free army and government manuals

Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it. Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it... They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends?

I am setting this document FREE. This document was made by the US Government and is NOT protected by Copyright. Feel free to share, republish, sell and so on.

I am not asking you for donations, fees or handouts. If you can, please provide a link to liberatedmanuals.com, so that free manuals come up first in search engines:
