1. SCOPE

This document describes the procedure for performing a Comprehensive Performance Test (CPT) of

the Power Distribution Unit (PDU). This involves setting up the PDU Test Stand, verifying that

prerequisite PDU tests have been completed, logging of equipment used and personnel participating,

execution of the tests, and logging of test results.

The CPT verifies the functions of all external interfaces on the PDU Box, both primary and

redundant. These functions include providing 28V power, environmental monitoring, and receiving

commands from an SIU and a GASU. Testing involves exercising the PDU external interfaces as

they would be used in normal LAT operation. The CPT is a relatively high-level test and does not

test every design requirement in the PDU. Successful prerequisite PDU tests together with a

successful CPT verify that a PDU has met all design requirements.

The Limited Performance Test (LPT) is a subset of the CPT. Test steps that are part of an LPT are

identified in the following sections.

Portions of the CPT are performed under high and low voltage and high and low clock conditions.

5.1.4 Participant List

This section provides a data sheet to record test participants.

Record all test participants in the data sheet.




5.2 Test CPT and LPT Procedures

The EUT is the assembled PDU Box (LAT-DS-01696). The EUT serial number is the 4-digit part of

the GLATxxxx barcode number affixed to the PDU chassis. Record this number on the test data

sheets as required and enter them in the Run Control Main application window when asked.

The tests in this document require the user do the following things:

Mate and demate cables and BOBs in the EGSE setup

Use an oscilloscope and multi-meter

Read the current display on the power supply

Visually verify that LEDs on the PDU Test Box illuminate

Set DIP switches on the PDU Test Box

Configure the GASU to run from an external clock source

Open the Run Control Main application of LATTE and run Python scripts




5.2.1 Pre-Operation Verifications

This section details the pre-operation verification checks before testing the EUT.

To perform the pre-operation verification checks:

Follow ESD processes during this checkout.

Prior to the connection of any hardware to other electronics, it shall be verified that all power

supplies, signal generators, VME racks, and any other test and measurement

equipment shall be connected to the same AC ground. The simplest way to do this is

to connect all AC-powered equipment to the same power strip. In cases where this is

not practical (e.g. possibly a thermal-vacuum test), greater care must be taken to

verify there are no floating grounds since this would represent a hazard to the

electronics.

Leave all connector savers in place until the actual flight mate is to be made. The AIDS provides

authorization to install and remove connector savers.

All flight mates and demates must be completed and entered into the mate demate log before

measurements are made or testing can start.

1) Notify QAE that testing is expected to start, so the QAE can arrange to be present for the

setup and start of testing. Record in the data sheet.

2) Verify that the Test Readiness Review has concluded and all parties have signed the cover

sheet. Record in the data sheet.

3) Record the serial numbers and locations per the data sheet.

4) Turn OFF the power on the LAT, or the EGSE. Record in the data sheet.




5) Set the DMM to the auto-ranging setting. Record in the data sheet.

6) Measure DMM lead resistance by connecting the two leads together. Record in the data sheet.

7) Tie the BOB chassis to technical ground. Measure the resistance between the BOB chassis and

technical ground. Record in the data sheet.

8) Remove all shorting plugs from the BOB. Record in the data sheet.

9) Measure the resistance between the EUT chassis and technical ground. Record in the data

sheet.

10) Measure the resistance between the test equipment chassis and technical ground. Record in the

data sheet.

11) Verify connector savers are on all flight hardware (install the connector savers per

authorization from an AIDS if necessary). Record in the data sheet.

12) Verify that the test equipment and participant lists have been completed.




5.2.2 Powering the GASU DAQ Subsystem (CPT)

This section is performed only for the CPT. This test verifies the PDU and GASU can be switched

ON via the SIU, and that the PDU can supply full power to the GASU.

1) Configure the LAT-DS-04309 cable.

This test procedure requires one LAT-DS-04309 cable and uses the ring lug option of this cable.

Rev 02 and later of this cable includes these termination options. Refer to the cable drawing LAT-

DS-04309 and the Figure below for the following steps:

Mate Cable LAT-DS-04309 Part A to Part BD and Record in the data sheet.

LAT-DS-04309 Cable Drawing, Parts




2) Turn ON the 28VDC Xantrex power supply.

3) Set the power supply output at 28.4V and set the current limit to 30A.

4) Record the voltage output and record the current limit setting of the power supply per the data

sheet.

5) Turn OFF the power supply.

6) Configure the PDU Test setup per the steps below and referenced in the following Figure.

a) Mate LAT-DS-04309 by connecting the red wired lugs to the positive terminal of the

power supply and the black wired lugs to the negative terminal of the power supply.

Record in the data sheet.

b) Mate LAT-DS-04307 JL5 flying cable from Test Box to PDU JL5. Record in the data

sheet.

sheet.

d) Mate LAT-DS-03400 JL7 pigtail from Test Box to LAT-DS-04304 J20. Record in the

data sheet.

e) Mate LAT-DS-04304 J78 to PDU JL7. Record in the data sheet.

Note: All mates and demates to the PDU under test are made at the connector saver only.

Only an AIDS provides the authorization to mate and demate flight connectors.

f) Mate LAT-DS-03400 JL8 pigtail from Test box to LAT-DS-04304 J20. Record in the

data sheet.

g) Mate LAT-DS-04304 J78 to PDU JL8. Record in the data sheet.

h) Hard ground the return bar of the Xantrex power supply. The PDU case and the return

bar must be connected to the same ground.




Powering the GASU DAQ Subsystem Test Setup

7) At the front panel of the PDU test box, verify that DIP switches SW5 and SW6 are all in the

OFF (up) position for all switches.

8) Turn ON the PDU Test Box (the fans).

9) Verify that the cooling fans in the PDU Test Box are ON.

10) Turn ON the Xantrex power supply.

63) Repeat steps 7 through 60 recording voltages and currents per the JL-4 data sheet. This time

the DIP switches must be set to power each PDU using the RDNT FEED (step 12 and 41).




Calculate Power from Test Results:

64) There are four power totals to calculate, Prim PDU with JL3, Rdnt PDU with JL3, Prim PDU

with JL4, and Rdnt PDU with JL4. The following statements apply to cables from the PDU

output connectors to the test loads.

• The constant of 25 Ohms/1000 ft for AWG24 wire is used to calculate the power lost

in cables from the PDU output connectors to the test loads.

• The resistance of one cable is based on the approximation of 2 wires on the hot and 4

wires on the return.

• The cable (LAT-DS-04308) length is “LEN” in inches measured from end-to-end

including connector bodies. Record LEN in the data sheet.

Complete the calculations for Prim PDU power consumption using the data from steps 24

through 33 as follows:

a) PPowIN = (VPS – IPS * R04309) * IPS

b) PPow30 = VR11 * [(VR11 – VD3) / 3300 + VMP1413 / 30] * 3

c) PPow25 = VR32 * [(VR32 – VD6) / 3300 + VMP2019 / 25] * 16

d) PPowGASU = VGASU * IGASU

e) PPowCable30 = [(VR11 – VD3) / 3300 + VMP1413 / 30]2 * (0.025) * (LEN / 12) * (3 / 4) * 3

f) PPowCable25 = [(VR32 – VD6) / 3300 + VMP2019 / 25]2 * (0.025) * (LEN / 12) * (3 / 4) * 16

g) PPowPDU = PPowIN – PPow30 – PPow25 – PPowGASU – PPowCable30 – PPowCable25

h) Record the Prim PDU power in the data sheet.




Complete the calculations for Rdnt PDU power consumption using the data from steps 47

through 56 as follows:

i) RPowIN = (VPS – IPS * R04309) * IPS

j) RPow30 = VR11 * [(VR11 – VD3) / 3300 + VMP1413 / 30] * 3

k) RPow25 = VR32 * [(VR32 – VD6) / 3300 + VMP2019 / 25] * 16

l) RPowGASU = VGASU * IGASU

m) RPowCable30 = [(VR11 – VD3) / 3300 + VMP1413 / 30]2 * (0.025) * (LEN / 12) * (3 / 4) * 3

n) RPowCable25 = [(VR32 – VD6) / 3300 + VMP2019 / 25]2 * (0.025) * (LEN / 12) * (3 / 4) * 16

o) RPowPDU = RPowIN – RPow30 – RPow25 – RPowGASU – RPowCable30 – RPowCable25

p) Record the Rdnt PDU power in the data sheet.

65) Repeat the calculations of step 64 for the data set corresponding to JL4 supplying power to

the PDU Box.




5.2.8 Calibrating the Temperature and Voltage Monitors on the PDU (CPT)

This section is executed during CPT only. This test determines the accuracy for all voltage and

temperature monitoring points.

Note: This section outlines the temperature monitor test without the use of LAT-DS-05829 analog

mux board. Thermal Vacuum testing will require the use of this board. The necessary

instructions for using the analog mux board are included separately in the Thermal Vacuum

Test document.
