WARNING SUMMARY

This warning summary contains general safety warnings and hazardous materials warnings that must be understood and applied during operation and maintenance of this equipment. Failure to observe these precautions could result in serious injury or death to personnel. Seek medical attention as required.

FIRST AID

For First Aid or artificial respiration, see TC 4-02.1, First Aid.

WARNING

Isopropyl alcohol is flammable and toxic. To avoid injury, keep away from open fire and use in well ventilated area.

If FWS-I is operated with eyecup/Shroud missing, light emitting from the eyepiece may be visible to the enemy and could result in personal injury.

When depressing the eyecup, and maintaining a good sight picture, ensure there is sufficient space between the eye and the FWS-I so that normal recoil of the weapon will not harm the operator.

Ensure weapon is clear and safe before installing/removing bracket and/or FWS-I to or from weapon, and before sight alignment. A loaded weapon may accidentally discharge causing injury or death.

Unit deliberate DECON SOP must be followed, since the following procedures are not for total decontamination. Protective mask and gloves should be worn when handling until total decontamination is completed by the DECON site.

Do not touch, ingest, or inhale particles or fragments of a broken objective lens. Lens contains Germanium that may cause irritation to eyes, skin, upper and lower respiratory tracts, or gastrointestinal tract. If contacted, flush eyes or skin with large amounts of water. If ingested, DO NOT induce vomiting. Rinse mouth with water and give victim 2-4 cupfuls of milk or water. Fragments of lens may be sharp enough to cut personnel if touched.

Do not attempt to recharge non-rechargeable batteries as fire or explosion may occur causing death and/or serious injury to personnel.

b

Do not open battery, dispose of in fire, heat above 212°F (100°C), expose to water, recharge, put in backwards, or mix with used or other battery types. Battery may explode or leak and cause injury to personnel.

Using AA batteries other than 1.5V will cause damage to the sight and may explode causing serious injury to the user. DO NOT USE

BATTERIES OTHER THAN 1.5V.

CHAPTER 1

GENERAL INFORMATION

SCOPE

Type of Manual

This manual contains a system description, operating procedures, and troubleshooting procedures for the FWS-I. It also contains Operator Level PMCS procedures and Operator Level maintenance procedures.

Model Number

AN/PAS-35

Purpose of Equipment

The FWS-I is a lightweight, modular, self-contained, battery operated, thermal imaging system for reconnaissance, surveillance and target acquisition for individual weapons during daylight, darkness, adverse weather and obscured battlefield conditions.

MAINTENANCE FORMS, RECORDS, AND REPORTS

Department of the Army forms and procedures used for equipment maintenance will be those prescribed by (as applicable) DA PAM 750-8, The Army Maintenance Management System (TAMMS) User’s Manual; AR 700-138, Army Logistics Readiness and Sustainability.

CORROSION PREVENTION AND CONTROL (CPC)

CPC of Army materiel is a continuing concern. It is important that any corrosion problems with this item be reported so that the problem can be corrected and improvements can be made to prevent the problem in future items.

Corrosion specifically occurs with metals. It is an electrochemical process that causes the degradation of metals. It is commonly caused by exposure to moisture, acids, bases, or salts. An example is the rusting of iron.

Corrosion damage in metals can be seen, depending on the metal, as tarnishing, pitting, fogging, surface residue, and/or cracking.

Plastics, composites, and rubbers can also degrade. Degradation is caused by thermal (heat), oxidation (oxygen), solvation (solvents), or photolytic (light, typically UV) processes. The most common exposures are excessive heat or light. Damage from these processes will appear as cracking, softening, swelling, and/or breaking.

0001-2

The US Army has defined the following nine (9) forms of corrosion used to evaluate the deterioration of metals. These shall be used when evaluating and documenting corrosion.

UNIFORM (or general attack): Affects a large area of exposed metal surface, like rust on steel or tarnish on silver. It gradually reduces the thickness of the metal until it fails.

CREVICE: Occurs in crevices created by rubber seals, gaskets, bolt heads, lap joints, dirt or other surface deposits. It will develop anywhere moisture or other corrosive agents are trapped and unable to drain or evaporate.

SELECTIVE LEACHING: One element, usually the anodic element of an alloy, corrodes away, leaving the cathodic element. This can create holes in metal.

INTERGRANULAR: Metal deterioration caused by corrosion on the bonds between or across the grain boundaries of the metal. The metal will appear to be peeling off in sheets, flaking, or being pushed apart by layers. A particular type of intergranular corrosion is exfoliation.

PITTING: This can result from conditions similar to those for crevice corrosion. Pits can develop on various materials due to their composition. Rifle boxes are big victims of pitting.

EROSION: Results when a moving fluid (liquid or gas) flows across metal surface, particularly when solid particles are present in the fluid. Corrosion actually occurs on the surface of the metal, but the moving fluid washes away the corrosion and exposes a new metal surface, which also corrodes.

FRETTING: Occurs as a result of small, repetitive movements (e.g., vibration) between two surfaces in contact with each other. It is usually identified by a black powder corrosion product or pits on the surface.

GALVANIC: Occurs when two different types of metal come in contact with each other, like steel bolts on aluminum, for example. This is a common problem on aircraft because of their mix of metals.

STRESS: Term used to describe corrosion cracking and corrosion fatigue.

Where an item is not ready/available due to one of these forms of corrosion, it shall be recorded as a corrosion failure in the inspection record and the appropriate code (170) for corrosion shall be used when requesting/performing maintenance.

SF 368, Product Quality Deficiency Report should be submitted to the address specified in DA PAM 750-8, The Army Maintenance Management System (TAMMS) User’s Manual.

DESTRUCTION OF ARMY MATERIEL TO PREVENT ENEMY USE

Destruction of Army materiel to prevent enemy use shall be in accordance with TM 750-244-2 (Procedures for Destruction of Electronic Materiel to Prevent Enemy Use).

0001-3

REPORTING EQUIPMENT IMPROVEMENT RECOMMENDATION (EIR)

THEORY OF OPERATION

INTRODUCTION

This work package contains functional descriptions of the FWS-I and explains how the major components interact with the system.

FWS-I

The FWS-I, when used in conjunction with a day optic, allows the FWS-I displayed output scene imagery to serve as the input for the day optic. The FWS-I, when used in conjunction with the ENVG-B, provides rapid target acquisition capability by displaying the FWS-I imagery into the ENVG-B display. There are multiple RTA modes:

PIP - Simultaneous display of full weapon sight imagery with weapon sight reticle, Picture in Picture (PIP), and ENVG-B imagery.

FWS - Full Weapon Sight (FWS) imagery with weapon sight reticle displayed in the ENVG-B.

RTA - Partial weapon sight imagery with reticle spatially aligned (bubble) with the thermal imagery of the ENVG-B.

SYSTEM BATTERY INDICATOR

NOTE

Primary battery is the 1.5V Lithium AA L91. Use of any other type of AA batteries will significantly impact the operational performance.

FWS-I has a Battery Charge Indicator that indicates the charge/discharge state of the batteries. When linked together, FWS-I and ENVG-B battery states are displayed in the ENVG-B eyepiece.

Batteries should always be replaced as a set. Never intermix with partially used batteries or other battery types. Battery door has visual indicators on the outside of the door to identify correct orientation of the batteries for installation.

AUGMENTED REALITY/RAPID TARGET ACQUISITION BATTERY PACK

ASSEMBLY (AR/RTA-BPA)

The AR/RTA-BPA provides rapid target acquisition capability to view the boresighted/zeroed FWS-I weapon sight reticle in the ENVG-B display, enabling the user to accurately engage targets without the use of active lasers. The AR/RTA-BPA transfers data and power between the AR/RTA-BPA through the HMA to the ENVG-B goggle and also transmits data wirelessly between the AR/RTA-BPA and FWS-I.
