SECTION 1 GENERAL INFORMATION

NAVAIR 01-75PAC-121-1. GENERAL. 1. This Crew Station Maintenance Manual (CSMM) is one of a series of manuals which provide the experienced technician with information and maintenance data required for readiness testing and organizational level maintenance of avionic equipment installed in the P-3C aircraft. This CSMM is supplemented by NAVAIR 01-75PAC-2-5, Integrated Technician Station Organizational Maintenance Instruction Manual (MIM). Manuals in the CSMM-series cover avionic equipment by crew station groupings in correspondence with like groupings in the MIM-series manuals. Maintenance coverage in this CSMM and the associated MIM, which is limited to specific production blocks of P-3C aircraft, is identified by Naval Bureau Number (BUNO). The coverage not limited by BUNO is applicable to all P-3C aircraft. For a complete listing of aircraft series, including BUNO and corresponding Lockheed serial numbers with cross-referencing, see NAVAIR 01-75PAA-2-1. verify the operational status of the avionic system. The tests use system test programs, Built-In Test Equipment (BITE), off-line test procedures, and portions of the operational program as applicable. 4. Section 3 and subsequent (hardware sections) are each dedicated to a specific system or functional grouping of equipment. The section number assigned to a system will, in all instances, be consistent between the CSMM and its associated MIM. Within the hardware sections the following conventions apply: a. When two (2) or more types of equipment are used for the same purpose, the same section number applies to all, and an alphabetical suffix is used to differentiate between types. Aircraft applicability serialization is shown on the tab sheets. When two (2) or more configurations exist within the same section, the minor differences are shown by delta notes; extensive differences are illustrated by separate figures, and serial number applicability is included in the figure title. Major signals are shown as double width lines and flow horizontally throughout the diagram. Block outlines adhere to the following conventions: (1) (2) (3) (4) (5) Solid line () a discrete component; disassembly or repair not normally possible Single dash line ( - ) unit, black box, or dust cover of a functional assembly Double dash line ( - - ) a removable module Triple and greater dash line ( - - - ) removable sub or sub- submodule Continuous dash line (- - - - -) a single block illustration of a multiunit system or an airframe enclosure or pod; i.e., IRDS, ESM. m. n. k. h. f. Partial or fractionalized illustrations are indicated by a zig-zag line in either upper, lower, or side outline, which indicate additional portions appear elsewhere in the same drawing. Absence of a zig-zag line does not imply an item is complete, but rather that the part shown is the only part in that drawing. Broken or air-connected lines or cables use a letter enclosed by a square and accompanied by a reference to the sheet number of the continuation. Lines terminated with a circuit reference such as G-8, L-24, R-122 refer to wiring diagrams indexed in Section 2 of each wiring data manual table 2-1. Table 2-1 cross indexes from circuit reference to the specific NAVAIR 01-75PAC-2-13 Series and NAVAIR 01-75PAC-2 Series manual for that diagram. Major test points are identified on signal flow diagrams, tables, charts, and illustrations by use of a numeral enclosed in a star ( 1 ), but are referred to in the text as TP along with the applicable reference designator (2A4TP1). j. System signal flow diagrams (first level) provide a composite simplified illustration of all active elements involved in a common function. Subsystem signal flow diagrams (second level) provide information covering a functional group, such as HF 1 (AN/ARC-161). System functional signal flow diagrams are special purpose diagrams showing a function of a multipurpose system, such as receive, transmit, azimuth distribution, and BITE. Functional blocks are used to show internal signal flow of equipment maintained at the unit (black box) level. Equipment maintained to the module level shows signal flow to the module level with text descriptions inside the module outline. System and Subsystem interface buses are labelled according to their use. Table 1-1 lists the types of interfaces and their definition.

PURPOSE AND SCOPE. 1. The purpose of this CSMM is to provide a basic manual covering readiness testing, system interfacing, signal flow, and maintenance procedures for avionic equipment located at or controlled by the technician station. The Integrated Technician Station MIM supports the CSMM by providing: a. b. c. d. Descriptive data on operating controls and indicators. Descriptive data supporting signal flow diagrams in this CSMM. Maintenance philosophy. Maintenance procedures (when needed to support procedures in the CSMM) covering testing, troubleshooting, alignment and adjustment, servicing and removal/installation procedures. Peculiar support equipment maintenance. c. d.

Information of particular interest to avionic personnel is: a. b. c. Ground safety precautions and emergency procedures. Ground air conditioning. Ground electrical power. 6. 4. NAVAIR 01-75PAA-2-15, Connector and Wire Repair Procedures, is used for detailed information for repairing wiring and connectors. NAVAIR 01-1A-505, Installation Practices for Aircraft Electric and Electronic Wiring, provides additional information. NAVAIR 01-75PAC-4 Series, Illustrated Parts Breakdown manuals, are the authoritative source for usage and parts replacement information and take precedence over any such information provided in any other manual. NAVAIR 01-1A-8, Aircraft Structural Hardware for Aircraft Repair, applies in use of maintenance and torque values relating to nuts, bolts, screws, and fasteners, unless specific directions are provided by the manual in use. NAVAIR 01-75PAA-2-2.1, Corrosion Control, Cleaning, Painting, and Decontamination, provides coverage to prevent, detect, identify, and properly treat and repair corrosion. NAVAIR 01-75PAA-0, Technical Documentation List, contains an indexed listing of all applicable P-3 manuals. The manual user should consult OPNAVlNST 4790.2 for reporting discrepancies in this manual.

AN ELECTRONIC RACK OVERTEMPERATURE CONDITION EXISTS WHEN AN ELECTRONIC RACK REACHES A TEMPERATURE OF 57.2 (1.7) _C (135 (3) _F). INDICATIONS THAT A RACK HAS REACHED THIS CONDITION ARE THE OVERHEAT LIGHT AT THE RACK COMES ON, THE RACK OVHT LIGHT ON THE CENTER INSTRUMENT PANEL COMES ON, AND IF THE AIRCRAFT IS ON THE GROUND (WEIGHT ON WHEELS), THE RACK OVERHEAT SIGNAL HORN SOUNDS. THE RACK OVERHEAT WARNING CIRCUIT BREAKER ON THE MAIN DC BUS CIRCUIT BREAKER PANEL APPLIES 28 VDC TO THE SOLENOID OF ALL RESET SWITCHES. THE OVERHEAT WARNING AUXILIARY RELAY (THROUGH THE ENERGIZED CONTACTS OF THE SCISSOR SWITCH RELAY NO. 1) AND TO THE TIMER.

WHEN AN OVERHEAT TEMPERATURE SENSOR (LOCATED IN EACH RACK) CLOSES, A GROUND SIGNAL TURNS ON THE RACK OVERHEAT LIGHT ON THE RACK AND THE RACK OVHT LIGHT ON THE CENTER INSTRUMENT PANEL. THE GROUND SIGNAL THAT TURNS ON THE RACK OVHT LIGHT IS ROUTED THROUGH THE NORMALLY CLOSED CONTACTS OF THE RESET SWITCH. THE GROUND SIGNAL IS ALSO ROUTED TO THE RESET SWITCH SOLENOID FROM THE OVERHEAT TEMPERATURE SENSOR. THE RESET SWITCH DOES NOT CLOSE UNTIL THE RESET TOGGLE HAS BEEN MANUALLY PLACED TO THE SOLENOID-HELD MOMENTARY POSITION.

SETTING THE RESET SWITCH TO THE SOLENOID-HELD MOMENTARY POSITION INTERRUPTS THE GROUND SIGNAL FROM THE OVERHEAT TEMPERATURE SENSOR TO THE RACK OVHT LIGHT ON THE CENTER INSTRUMENT PANEL AND THE OVERHEAT WARNING AUXILIARY RELAY. THE ACTION CAUSES THE RACK OVHT LIGHT TO GO OUT AND THE RACK OVERHEAT SIGNAL HORN TO SHUT OFF. THE REASON FOR THIS ACTION IS TO ALLOW DETECTION OF AN OVERTEMP CONDITION IN ANOTHER ELECTRONICS RACK. THE SWITCH STAYS IN THE DOWN POSITION AND THE RACK OVERHEAT DROPS BELOW THE LOWER LIMIT OF 53.3_C (128_F) AT WHICH TIME THE GROUND SIGNAL FROM THE OVERHEAT TEMPERATURE SENSOR IS REMOVED FROM THE RESET SWITCH SOLENOID.
