USER MANUAL

V50 BACKGROUND

V50 testing is a statistical tool used for evaluating the penetration re-

sistance of materials involved in ballistic armour to specic laboratory fragment simulators. The V50 test is used extensively in ballistic material

design, in tandem with product development. Under some conditions,

it may also be used to compare relative performance of fragmentation resistant materials or armour, so long as the materials are identical in basic construction, e.g., comparing aramid soft body armour. The V50 limit cannot be used to compare dissimilar armour constructions, e.g., soft versus rigid materials. Care must be taken when interpreting V50 ratings due to the fact that the probability of an explosive device fragment

having the exact same physical properties as the simulated fragment

used during testing is essentially non-existent. There exist a number of different fragment simulators, both in terms of shape and size, thus it is necessary to stipulate the precise simulator that is being used to arrive at a V50 value for objective comparisons. Although standardized test methods exist for V50 determination, there still exist subtle variations in carrying out the actual test between different laboratories/manufacturers,

which may lead to small variations in the V50 results.

INSTALLING BATTERIES IN THE ONBOARD POWER

SUPPLY (OPS)

The EOD® 9/9A Helmet OPS is powered by 8 AA batteries.

A set of alkaline batteries will last up to 5 hours 20 minutes depending on the load applied. A set of rechargeable Nickel Metal Hydride (NiMH) bat-

teries provide an operating time of up to 4 hours 20 minutes for the same load.

Always make sure new alkaline batteries or fully recharged NiMH batteries are installed before each mission. Always use good quality batteries (1400 mAh or better, Diameter: 0.57”, Length: 1.99”). Med-Eng does not recommend the use of Nickel Cadmium (NiCd) batteries as they do not have

adequate capacity. Operation time will vary according to which helmet

features are used. To open the back cover, pull on both fasteners (A), at

the same time and then lift the cover.

NOTE: The battery type switch (B) must be set for the type of batteries installed. If the switch is set incorrectly, the battery life indicator on the remote will not provide an accurate reading.

IMPORTANT: If the SPS is used, battery types (alkaline or NiMH) used in

the SPS and OPS must match.

EOD® 9/9A HELMET

USER MANUAL

IMPORTANT: The batteries in the OPS (Onboard Power Supply) have

been designed to be inserted in one direction only according to polarity. Install batteries referring to the yellow graphic beside the battery type

switch.

WARNING: Prior to inserting batteries into the OPS, a basic but deliberate inspection should be conducted. This inspection is meant to detect the presence of corrosion and to conrm that there is no damage to the outside covering of the batteries. If a battery covering is abraded, ripped, torn or peeled away from the battery body or if any level of corrosion is detected, the battery should not be placed into the OPS. Damaged batteries should be disposed of in a safe manner.

WARNING: The OPS in the helmet should be inspected on a regular basis for damage, loose battery holders, and the presence of battery corrosion. If the battery holders are damaged or there is corrosion present they should be replaced prior to the helmet being used. If a bat-

tery holder retention spring does not provide enough force to maintain

a battery in position, it may be adjusted by squeezing the retention

springs closer together and then releasing.

USER MANUAL

CONNECTING THE SHIELDED POWER SUPPLY (SPS)

When the SPS is connected, power is automatically drawn from this source rather than from the OPS. When the SPS has been drained, power draw will automatically switch to the OPS. In combination with the OPS, the SPS (with alkaline batteries) will increase operation time up to 8 hours and 50 minutes, depending on which helmet functions are used.

NOTE 1: The increase and decrease buttons will not work to control the ventilation system. However, the red button can be used to initiate turbo

mode.

NOTE 2: The EOD® 9 Helmet may be connected to the Med-Eng legacy IPS/APS. The EOD

®

9A helmet should only be used with the SPS to

reduce Electro Magnetic Interference (EMI) and mitigate impact of Electronic Countermeasures (ECM). The EOD® 9/9A Helmet is not designed

for operation with an EOD 7B Power Supply.

INSTALLING BATTERIES IN THE SHIELDED POWER

SUPPLY (SPS)

Use eight (8) Alkaline or ten (10) Rechargeable NiMH C cell batteries in the SPS. Always install batteries so that the positive ends face toward the door. When using alkaline batteries, position them as shown. The fth tube should be lled only when rechargeable batteries are being used.

Med-Eng does not recommend the use of Nickel Cadmium (NiCd) batteries as they do not hold adequate charge. Some military issued batteries do not meet the minimum height requirement and must not be used in the SPS. Many off-the-shelf batteries do not meet the minimum capacity requirement. Always use good quality batteries that meet the following requirements:

Minimum Height 1.89” (4.80 cm)

Typical Diameter 1.0” (2.54 cm) Minimum Alkaline Capacity 5 Ah

If batteries are not oriented correctly: The SPS will beep 3 times. If using the OPS, the battery life light on the remote will illuminate yellow.

CAUTION: Do not use batteries that have cracked or missing heatshrink.

CAUTION: Use either ALL ALKALINE or ALL RECHARGEABLE NiMH batteries in the SPS. Never mix battery types.

IMPORTANT: Battery types (alkaline or rechargeable NiMH) used in the

SPS and OPS must match.

USER MANUAL

OPERATING THE SPEAKERS

The Environmental Awareness System (EAS) is linked to a stereo headset system inside the helmet. Omnidirectional microphones and a

stereo amplication system allows the user to hear ambient sounds and

to distinguish from which direction a sound originates. The EAS is fully

compatible with duplex communication systems such as the HW-300 and

wireless systems. Automatic gain control (AGC) automatically increases or decreases volume levels inside the helmet to ensure optimal sound

quality, as a function of ambient sound level. The EAS incorporates an ambient sound amplier cut-out feature to block ambient sounds that

may damage the user’s hearing.

The speaker indicator light will illuminate automatically as soon as the system is powered. A green light indicates that the function is active.

A red light indicates that the function is faulty. For the rst 30 seconds, the increase/decrease buttons can adjust the speaker volume. After 30

MONITORING BATTERY LIFE

The Battery Charge Light (B) toggles between green, yellow and red to indicate the remaining battery charge of the source from which power is being drawn. When the SPS is connected, power is automatically drawn from this source rather than from the OPS. When the SPS has been

drained, power draw will automatically switch to the OPS. To determine

the charge of batteries in the OPS at any time, disconnect the SPS.

Green 75%-100%.

TROUBLESHOOTING GUIDE

System does not start up: the most common cause is insufcient

power.

- Cell orientation may not be correct; voltage below dead zone of 8V. Check label for orientation & reinstall batteries correctly.

- Contact force on battery holder spring may be too weak. Refer to Pre-

ventative Maintenance.

- Cells may not be properly seated in the battery holder.

- Cells may be discharged. See section below.

- Remote controller is not connected properly.

System starts but operates for only a short time before shutting down.

- Cells may be discharged; Open circuit voltage must be at least 8.4V on NiMH setting and 10.5V on Alkaline setting. Preferred total battery potential

is 12V Alkaline and 10V NiMH.

- Chemistry selector switch is not set for the correct battery in use for both SPS and OPS. If the OPS is used for backup to the SPS, ensure Chemistry switch setting is compatible for both sources (i.e. same type of battery is used for both).

System does not respond to control.

- Ensure remote controller connector is fully inserted.

- Potential water or condensation inside electronics. Return for servicing. Some system features do not operate.

- Check that the connector for the non-operating feature is fully inserted.

- Check the connector pins for worn contact plating, breakage or bending.

No sound on one side.

- Ensure that the speaker pad is properly aligned with the user’s ear.

- Ensure that the connector is fully inserted.

- Check speaker wire for damage

- Carefully remove speaker from ear pad, and check solder joints

SUGGESTED PACKING PROCEDURE

Position the EOD® 9/9A Helmet components in the Carry Bag as indicated:

Manual

DVD

Steel Visor (if applicable)

Visor Cover

1. Remove the batteries from SPS and discard in accordance with applicable disposal regulations or store in a manner to prevent the possibility

of short circuit. Make sure the SPS is snapped into the pocket.

2. Install the Visor Cover(s).

Note: If present, install the Steel Add-On as the visor cover. This will prevent the steel add-on from moving around and damaging other helmet components during transport.

3. Fasten the retention system and do not stack anything inside of the

helmet to prevent the visor from being scratched. Pack the bag with the rest of the components as shown. Place the helmet in the carry bag so

that the visor faces away from the SPS.

NOTE: If shipping the helmet, cinch the retention system as tight as it will go to prevent the visor from being scratched. It is also recommended that before shipping, a visor applique be applied. This will also prevent the visor from being scratched.

4. Pack the BA Kit Bag in front of the helmet visor.

CARE AND MAINTENANCE

PREVENTIVE MAINTENANCE

Always remove batteries from OPS and SPS after use.

Med-Eng strongly recommends the use of new alkaline or fully charged Ni-MH (Nickel-

Metal Hydride) batteries before each use. Whether a new or rechargeable battery is used, Med-Eng suggests all batteries are examined for any signs of leakage, swelling,

off-gassing, corrosion, casing or any other damage prior to and post use. If any evidence of

damage, refer to Warning and Cautions in this document. Discard used or damaged batteries in accordance with local hazardous waste regulations should any evidence of damage be noted.

Optimum temperature range for storing/charging NiMH cells is 10°C to 30°C. Charging is

disrupted below 0°C (and may be dangerous if vent cap leaks) or above 40°C.

- Never overcharge.

- Never reverse-charge cells.

- Never overdischarge at high current.

Prior to installing fresh AA cells, check that the battery holders are rmly secured to the EAS plastic mold. If loose, re-secure the holders by tightening the #4 Phillips screws located below the battery orientation label. Do not over tighten screws and do not use thread

locker or cyanoacrylate adhesives to resecure the screws.

Check the battery holder clamp insertion force and cell contact tension from battery holder terminals after each 30 insertions; if these forces are less than 50% of a new holder, carefully pinch the opposite ends of the terminals and squeeze the opposite ends together approximately 1/8 inch to reset spring tension.

After every 10 battery insertions, clean the holder and battery contacts. Wipe the contacts with isopropyl alcohol and a cotton swab. Visually inspect them and replace any corroded hardware. Commercial batteries, used in missions where air temperature exceeds 40°C for

extended periods of time, can leak electrolyte. In this case, inspect and clean contacts after

each use. Be careful not to spread contamination on to printed circuit boards or connectors.

If it is necessary to transport the helmet or store it for a period of time, it is mandatory to

remove all batteries from the system and discard in accordance with applicable disposal regulations or store in a manner to prevent the possibility of short circuit. If helmet is to be shipped by air, lands, or sea, ensure compliance with applicable carrier’s battery transport

regulations.

Replace the air lter to the fan inlet when the light intensity from a 60W incandescent light source passing through a dirty lter is less than ½ the light intensity of a new lter.

Check and retighten any loose screws which may be supporting connectors, fan mounts and battery holders.
