SECTION V

FAULT ISOLATION/MAINTENANCE AND REPAIR

5.1

GENERAL

This

section provides the procedures for Fault Isolation, maintenance and repair

to

the

Lowest Repairable Unit

(LRU)

level.

5.2

DISASSEMBLY

Disassembly should be only to the extent necessary to accomplish the repair or replacement

of

the defective LRU.

Procedures for the disassembly

of

major modules and assemblies are given in the following paragraph.

15.2.1 TOP OR BOTTOM COVER REMOVAL I

Refer to Figure 5.2.1.1

a)

Remove the three screws

at

the rear

of

the cover.

b)

Pull the cover up and back from the front panel.

5.3

TEST SET UP

js.3.1

PRELIMINARY!

5.4

§Jig

a)

Connect RCU-931 0

to

AC or DC power and turn ON.

WARNING: For personal safety and to prevent damage to voltage

sensitive components in the remote control unit, always turn OFF the RCU-931 o whenever resealing printed circuit cards

(PC), LRU'S and when replacing fuses.

ls.4.1

PRELIMINARY I

The

BITE

of

the RCU-931 0 provides immediate LRU faults. The Surveillance BITE is controlled by the

microprocessor on

CPU Assembly 3A2A 1. It checks the operational status

of

the LRU's with the exception

of

the +28 V Regulator 3A3A 1. This LRU has a self-surveillance BITE non-dependent upon CPU Assembly 3A2A1. The front panel "LCD" will display a plain language "FAULT MESSAGE", the "FAULT" Red LED will illuminate

on the front panel (See Figure 5.4.1.1 and on the faulty LRU (see Figure 5.4.1.3)).

The

RCU-9310 Remote Control Unit can be tested independently, with or without a transceiver connected. With RCU-931 0 connected to selected input power turn ON remote unit and refer to figure 5.4.1.1 and perform the following steps

to

access the BITE menu.

0 receive audio circuits

have

been factory adjusted to provide

an

OdBm output signal from

an

OdBm

input signal from transceiver. The

RCU-931

0 is checked

and

aligned

as

a stand alone unit

by

connecting the unit

and

test equipment as shown

in

Figure 5.7.2.1. and accomplishing the following checks

and

alignments. Use Figures 5.7.1.2 and 5.7.2.2.

a)

Turn

on

RCU-931

0,

go

to

menu and turn 'OFF' the

1/0.

Select 'LOCAL', 'MTR-RCV', 'LINE' and 'LINE

1)

With 1000Hz OdBm input at Remote Audio J4 pins Band

D,

check for OdBm level at 3A2A5

J5

pins

5 and

2)

Measure audio level at 3A2A5 J3 pins Hand J

and

adjust 3A2A4

R8

as

required for a reading of .180

VRMS.

3)

5)

With

measure resistance between right side of 3A2A2 R 142 and ground. Adjust 3A2A2

R89

for

a 2K

reading. Turn RCU-9310 'ON'.

(

6)

Turn the Squelch Control fully clockwise, the audio output

of

the RCU-9310 speaker should

be

squelched. Change

the

Audio Oscillator

to

1OkHz

and return to

1OOOHz.

The speaker audio should (

be
