WARNING

RADIATION HAZARD

NICKEL-63 (Ni-63) Wipe test must be performed before and after any maintenance or testing of CAM. Contamination can become airborne by heated air and smoke from fire. Stand upwind of fire to avoid inhalation of possible contamination. The Chemical Agent Monitor (CAM) contains a beta radiation source in the quantity which requires a Nuclear Regulatory Commission (NRC) license to possess items which contain the source. The CAM contains 10 millicuries of Nickel-63. The Nickel-63 plated cylinder is the source which ionizes chemical agents allowing for their detection. If the CAM is lost or stolen, notify the NBC Officer/NCO and the local Radiation Protection Officer (RPO) immediately. Lost or stolen CAMs are reportable to the Nuclear Regulatory Commission (NRC) by the license holder. Report must be made through the local RPO to the Armament and Chemical Acquisition and Logistics Activity (ACALA) Safety Office, DSN 793-2965/2995/6228. The source is totally enclosed and protected by the CAM case. However the CAM is potentially dangerous if broken. SAFETY PRECAUTIONS 1.

Handle the CAM carefully.

2.

If CAM case is broken or cracked, inform the NBC Officer/NCO, and if available, the local Radiation Protection Officer (RPO).

3.

A CAM damaged beyond the repair capability of direct support should be wrapped in a plastic bag and shipped in original packing container, if available, to depot maintenance for repair. If skin contact is made with any area thought to be contaminated with Nickel-63, wash immediately with nonabrasive soap and water.

4.

Follow safety procedures for storage, shipment, and disposal in accordance with this manual, local regulations, AR 710-3 and AR 385-11.

TM 3-6665-343-23&P HOW TO USE THIS MANUAL This manual contains a number of features that enable the user to locate information easily. The table of contents contains a general list of information sections. A comprehensive cross-referenced index is located at the end of the manual. It will also help the user locate specific information. Chapter 1 contains introductory information. Topics of special importance include equipment description and data, location and description of major components, safety, and principles of operation. Chapter 2 contains information at the unit maintenance level. Topics of special importance include service upon receipt, preventive maintenance checks and services, troubleshooting, maintenance procedures and preparation for storage or shipment. Chapter 3 contains information at the direct support maintenance level. Topics of special importance include radiological safety instructions, service upon receipt, troubleshooting, maintenance, and preparation for storage or shipment. When a CAM arrives at Direct Support for repair, use the information in Chapter 3 to test, troubleshoot, repair and retest the CAM. Use the following steps as a guide: 1. Get the equipment required for testing and troubleshooting a CAM. This equipment is listed in para 3-12. Then prepare the Diagnostic Test Set (for use in testing and troubleshooting the CAM) as instructed in para 3-14. 2. Perform the operational check of the CAM presented in para 3-15. If you come to a part of the operational check that cannot be accomplished, refer to the symptom for the problem. (Para 3-11 lists possible symptoms that could occur during the operational check.) Turn to the page in the manual for troubleshooting the symptom. 3. Follow the troubleshooting logic tree for the symptom. The tree will refer you to a maintenance procedure or to further testing. Further testing consists of more detailed tests: cell test, leak test, pump test, and waveform test. 4. Turn to the maintenance procedure and perform the indicated maintenance action. The procedure begins with an initial setup: a listing of the tools and materials needed to complete the task, and the equipment condition prior to performance of the maintenance task. The equipment conditions are a list of the maintenance tasks that must be accomplished before the present task is started. Do the equipment condition tasks first. 5. The specific maintenance task is then performed. The task usually consists of removal and installation procedures. Once the specific task is completed, return to the beginning of the task at the equipment conditions listing. Reverse the order of equipment condition steps to place the CAM back into a fully assembled condition. 6. Return again to the troubleshooting tree for further direction in trouble analysis or additional testing. Tasks in the troubleshooting tree end by performing the operational check to see that the CAM has been completely returned to operational status. 7. Perform wipe test before returning to user (para 3-7). A Repair Parts and Special Tools List (RPSTL) that lists and authorizes spares and repair parts, tools, special tools, Test, Measurement and Diagnostic Equipment (TMDE), and support equipment required for performance of maintenance of the CAM is supplied in Appendix C.

SAFETY, CARE, AND HANDLING.

a. Rules and Regulations. The CAM contains a radioactive source which is controlled by the U.S. Nuclear Regulatory Commission (NRC) under Title 10 Code of Federal Regulations. AR 385-11 and 700-64 implement NRC regulations. Army-wide possession and use of the CAM is authorized by an NRC Byproduct Materials License issued to the Armament and Chemical Acquisition and Logistics Activity, Attn: AMSTA-AC-SF, Rock Island, IL 61299-7630. The license is issued on the basis of statements concerning procedures established for the life-cycle control of the CAM. The CAM units are issued to Army activities through the Armament and Chemical Acquisition and Logistics Activity National Inventory Control Point, (AMSTA-AC-CTC-D). The serial numbers of the CAM and drift tube module are tracked by AR 710-3, Chapter 4, Section 2. Please notify your Cell Serialization Surety Officer (CSSO) to process the serial number transactions with the DOD Central Registry.

1-2

TM 3-6665-343-23&P b. Wipe test. The wipe test (para 3-7) must be performed upon receipt and before and after all maintenance and testing is complete. c. Posting Requirements. Federal law requires certain notices, instructions, and standards be made available to all users of items which contain licensed radioactive material. In lieu of posting this information, pages are attached at the back of this technical manual for reference. These pages contain instructions about Title 10 Code of Federal Regulations, NRC Form 3 (Notice to Employees) and Public Law 93-438. d. Repair/Disposition. Unserviceable CAM will be returned to depot. e. Emergency Procedures. NOTE In any emergency event, radioactive contamination must be considered to be present until determined otherwise. (1)

Fire. In a fire emergency, the basic concern is possible airborne contamination carried out of the flames by the heated air and in the smoke. Firefighters should fight the fire from upwind, and wear portable air systems, if available. After the fire has been extinguished, debris must be surveyed for the presence of equipment containing Nickel-63 sources. The RADIAC meter AN/VDR-2 (with the beta window open) is suitable for detecting the location of the Nickel-63 sources. Wipes must be taken and evaluated to determine contamination location.

(2)

Equipment Destruction. In an equipment destruction emergency, parts of the equipment must be retrieved, and surveys for possible contamination must be done.

INTRODUCTION.

The CAM samples air in the immediate vicinity of the nozzle for the presence of G or H chemical agents. Air sample conditions a short distance away from the CAM may be quite different, and a change in wind direction could quickly bring a hazardous level of agent vapor to a previously safe area. An internal motor/pump assembly (sample pump) continually draws air in through the nozzle assembly. The air is then passed over a heated membrane assembly before being exhausted back into the atmosphere via an exhaust vent at the side of the nozzle assembly. Any agent vapor present in the air permeates the membrane assembly and the cell assembly. In the cell assembly, the vapor molecules are electrically charged (ionized) by a weak radioactive source in order that the vapor molecules can be detected. These charged particles are used to produce an electronic signal by means of a process called Ion Mobility Spectrometry (IMS). Agent ions in the cell assembly are swept towards a collector electrode which produces an electrical impulse for each ion received. The current produced by this electrode is analyzed by a microprocessor which drives the display assembly. From the characteristics of this signal, CAM determines the concentration of the nerve or mustard agent present and indicates the vapor hazard by displaying a number of bars on the display assembly. The closed cell assembly system air is circulated by a recirculating pump through molecular sieves which keep the system dry and chemically clean. The G/H mode push button switch reverses the voltages in the cell assembly to suit nerve or mustard agent vapor which have opposite charges when ionized. Acetone vapor is introduced into the closed circulatory system to stabilize the response of the CAM in the nerve agent mode.

TM 3-6665-343-23&P

Principles of Operation

1-9

TM 3-6665-343-23&P

The CAM has two operating modes, selectable by means of the G/H mode push-button switch: in the G mode, CAM monitors for nerve agents; in the H mode, CAM monitors for mustard agents. The selected mode is indicated on the display assembly by a G or H. An ON/OFF push-button switch applies 6 Vdc battery power to the CAM. Heater controllers and heaters keep the temperature of the nozzle, membrane, and cell constant for agent detection. A DC-DC converter changes 6 Vdc input to positive or negative 1 kv for cell operation. An analog-to-digital converter changes the varying cell analog output to digital for processing in the microprocessor. The microprocessor output is shown on the liquid crystal display. 1-10

TM 3-6665-343-23&P

THREE DOTS The three dots on the far right of the display are used normally only as a diagnostic indication. If at any time during normal operation the processor loses the Reactant Ion Peak (RIP) (i.e., the RIP, always monitored, does not meet the preset height and position criteria), the three dots will be activated. This would normally happen briefly after a mode change or during excessive dosage of agent or simulant (as they have a greater charge affinity than air). During this period, the unit will still operate normally as the processor is using the last known reference for the RIP (from RAM). If, however, the processor does not find a RIP again within about 30 minutes of its disappearance (normally this would be caused only by either gross contamination or equipment failure), a fault condition signal is given to the operator. This failure signal comprises all eight bars and the WAIT symbol flashing at a frequency of approximately 2Hz.

TM 3-6665-343-23P WARNING FLAMMABLE AND CORROSIVE HAZARD

Lithium-sulfur dioxide batteries contain lithium, sulfur dioxide and an electrolyte. Sulfur dioxide is an irritant gas. The electrolyte is flammable and highly corrosive. Do not immerse in water or decon solution, crush, or burn batteries. Do not attempt to recharge batteries or store at temperatures above 158°F (70°C). If a battery is mishandled or misused, the lithium may rapidly vent out, carrying with it the sulfur dioxide gas and the electrolyte, and it may heat up. If this happens, stay away until the smell of sulfur is gone. If you have to move the battery, move it outside by using a shovel or long tongs. Wear suitable protection when handling suspect batteries. A rapidly venting battery may create an explosive and corrosive hazard which may cause damage to skin and eyes. If the skin or eyes come in contact with the electrolyte, wash thoroughly with generous amounts of water, and seek medical attention. Dispose of batteries according to TB 43-0130 and local SOP.

INTRODUCTION. WARNING

RADIATION HAZARD

NICKEL-63 (NI-63) Wipe test must be performed before and after any maintenance or testing of CAM. When a CAM is sent to DS for repair, the performance of the CAM is first checked by an operational check. When a fault occurs during the operational check, the maintainer goes to the troubleshooting logic tree for the symptom of the fault. The troubleshooting logic tree leads the maintainer through step-by-step procedures to determine that there is a malfunction and then to isolate the trouble to the malfunctioning assembly or part. The logic tree will reference tests and maintenance procedures (in section IV) where needed. At any point during the referenced tests that the indications are not as required, the maintainer returns to the logic tree. The logic tree will tell the maintainer what to do if the test has failed. Once the CAM has been repaired, it is again checked by the operational check to determine that the CAM is ready for a mission.

GENERAL MAINTENANCE INSTRUCTIONS. The following general maintenance procedures are to be followed whenever performing maintenance on a CAM.

a. Inspect CAM, including case and display window for any cracked or broken parts. Replace any cracked or broken parts. b. Inspect all removed assemblies/parts for tears, breaks, indications of wear, and corrosion. Replace any parts showing these faults. c.

Observe all parts for cleanliness. If parts appear to have dust on them, blow the dust off.

d. Check the threads of all removed screws for the presence of Tuflok. If Tuflok no longer remains in the threads, replace the screw(s). e. Prior to working on a CAM, prepare a clean work surface. Follow work preparation instructions per Chapter 3, Section I. f. DO NOT remove a new CAM assembly/part from its packaging until you are ready to install it. This will keep the assembly/part clean and dry. g. Open the pneumatic loop of a CAM (opening the sieve pack, pump assembly, drift tube module, membrane, nozzle assembly) only long enough to make required tests and/or replacements.

WARNING

RADIATION HAZARD

NICKEL-63 (Ni-63) This CAM contains a beta radiation source in the quantity which requires a Nuclear Regulatory Commission license to possess items which contain the source. The CAM contains 10 millicuries of Nickel-63. WARNING Removal of the membrane assembly "opens" the pneumatically "sealed" drift tube module, therefore indirectly exposing the Ni-63 ionizing source. To avoid exposure, minimize the time spent performing this task. For further information on the Nuclear Regulatory Commission License, see Appendix E. CAUTION Removal of the membrane assembly exposes CAM's highly sensitive sensing device to outside contamination. Ensure that gloves are worn and appropriate precautions are taken to avoid equipment contamination. Avoid touching or getting gloves near membrane. A special membrane extraction tool is provided in the DTS lid. DO NOT ATTEMPT TO USE ANY OTHER TOOL. The membrane extraction tool has a built-in "stop" to avoid damaging the membrane; do not attempt to adjust or modify this tool. 3-124

TM 3-6665-343-23&P CAUTION Do not rotate membrane during removal as it may damage the heater grid. REMOVAL 1.

Slowly lower "opened" tool into the nozzle holder assembly and carefully engage its pins with the membrane holder's slots. Be very careful not to rotate the membrane during this action, as it may damage the heater grid lying directly behind it.

2.

Very gently pull the membrane out of its seat using only a straight ahead motion-DO NOT ROTATE. It may be necessary to gently rock the membrane extraction tool from side to side while gently pulling forward.

3.

Dispose of membrane as radioactive waste.

INSTALLATION 1.

SECONDARY PEAKS.

NOTE Secondary peaks are any visible peak other than the normal RIP. They may look much like the peaks that show when a CAM is exposed to simulant, but do not diminish and disappear within a few minutes. A secondary peak due to contamination can occur anywhere on the waveform, depending on the source of the contamination. However, do not consider a peak that occurs within 1 ms from the center of the RIP to be a secondary peak. A corresponding bar reading on the CAM may or may not be present. To become familiar with the types of peaks contamination causes, observe the response of a good CAM to simulant. k. Set CH1 VOLTS/DIV to 1. Set A and B SEC/DIV to 2 ms. Observe for secondary peaks occurring after the main peak in both the G and H modes. There should not be any secondary peaks. Secondary peaks indicate the presence of contamination (see below). If secondary peaks are present in waveform test, remove nozzle protective cap. If secondary peaks significantly decrease in amplitude, clean nozzle assembly area with a dampened cheesecloth and install a new protective cap. If secondary peaks are still present in waveform test, refer to troubleshooting symptom 12 (para 3-27). I. Set CH1 to DC and measure dc offset from zero in both the G and H modes: offset should be less than 1 V dc. If DC offset is greater than 1 V dc, refer to troubleshooting symptom 13, para 3-28. NOTE Wait a few seconds after switching modes to make peak measurements. m. Set CH1 to AC. Set A and B SEC/DIV on oscilloscope to 1 ms. Make the following reactant ion peak (RIP) measurements: (1) H mode peak height: greater than 1.5 V peak. (2) G mode peak height: greater than 1.5 V peak. n. If (G or H) peak heights are not within specifications, refer to troubleshooting symptom 14 (para 3-29).

Section I. INTRODUCTION B-1.

THE ARMY MAINTENANCE SYSTEM MAC. a. This introduction (Section I) provides a general explanation of all maintenance and repair functions authorized at various maintenance levels under the standard Army Maintenance System concept. b. The Maintenance Allocation Chart (MAC) in Section II designates overall authority and responsibility for the performance of maintenance functions on the identified end item or component. The application of the maintenance functions to the end item or component will be consistent with the capacities and capabilities of the designated maintenance levels which are shown on the MAC in column (4) as: Unit - includes two subcolumns, C (operator/crew) and O (unit) maintenance. Direct Support - includes an F subcolumn. General Support - includes an H subcolumn. Depot - includes a D subcolumn. c. Section III lists the tools and test equipment (both special tools and common tool sets) required for each maintenance function as referenced from Section II. d. Section IV contains supplemental instructions and explanatory notes for a particular maintenance function. B-2. MAINTENANCE FUNCTIONS. Maintenance functions will be limited to and defined as follows: a. Inspect. To determine the serviceability of an item by comparing its physical, mechanical, and/or electrical characteristics with established standards through examination (e.g., by sight, sound, or feel). b. Test. To verify serviceability by measuring the mechanical, pneumatic, hydraulic, or electrical characteristics of an item and comparing those characteristics with prescribed standards. c. Service. Operations required periodically to keep an item in proper operating condition; i.e., to clean (includes decontaminate, when required), to preserve, to drain, to paint, or to replenish fuel, lubricants, chemical fluids or gases. d. Adjust. To maintain or regulate, within prescribed limits, by bringing into proper or exact position, or by setting the operating characteristics to specified parameters. e. Align. To adjust specified variable elements of an item to bring about optimum or desired performance. f. Calibrate. To determine and cause corrections to be made or to be adjusted on instruments or test, measuring, and diagnostic equipments used in precision measurement. Consists of comparisons of two instruments, one of which is a certified standard of known accuracy, to detect and adjust any discrepancy in the accuracy of the instrument being compared.

B-1

TM 3-6665-343-23&P B-2. MAINTENANCE FUNCTIONS (CONT). g. Remove/Install. To remove and install the same item when required to perform service or other maintenance functions. Install may be the act of emplacing, seating, or fixing into position a spare, repair part, or module (component or assembly) in a manner to allow the proper functioning of an equipment or system. h. Replace. To remove an unserviceable item and install a serviceable counterpart in its place. "Replace" is authorized by the MAC and assigned maintenance level is shown as the 3rd position code of the SMR code. i. Repair. The application of maintenance services including fault location/troubleshooting, removal/installation, and disassembly/assembly procedures, and maintenance actions to identify troubles and restore serviceability to an item by correcting specific damage, fault, malfunction, or failure in a part, subassembly, module (component or assembly), end item, or system. j. Overhaul. That maintenance effort (service/action) prescribed to restore an item to a completely serviceable/operational condition as required by maintenance standards in appropriate technical publications (i.e. DMWR). Overhaul is normally the highest degree of maintenance performed by the Army. Overhaul does not normally return an item to like new condition. k. Rebuild. Consists of those services/actions necessary for the restoration of unserviceable equipment to a like new condition in accordance with original manufacturing standards. Rebuild is the highest degree of materiel maintenance applied to Army equipment.
