NAME DESCRIPTION

BATS ORE Offshore’s Broadband Acoustic Tracking System. A high accura-

cy USBL survey quality acoustic navigation system. Model 4460 &

4461.

Beacon Any underwater sound source. Sometimes abbreviated as "BCN".

Interrogate To cause a response from an underwater device such as a tran-

sponder.

Pinger An underwater sound source which transmits at a fixed preset rate,

asynchronously to a tracking device.

Responder An underwater sound source which responds to an electrical signal

(interrogated via a hardwired link) and returns with an underwater

acoustic reply. Sometimes abbreviated as "RSPDR".

Slant Range The range from a target to the listening hydrophone. (Computed by

the travel time from target to hydrophone multiplied by the speed of

sound in water.)

Telemetering

Beacon

Can either be a transponder or a responder. It outputs two replies in

response to an interrogation. The first reply is the navigation pulse

for the Trackpoint II and the second reply is the telemetry pulse. The

time delay between the two replies is proportional to the sensor out-

put on the telemetry beacon.

Trackpoint 3 ORE Offshore’s Model 4450 USBL Tracking System. A high accuracy

survey quality acoustic navigation system.

Transponder An underwater sound source which responds to an underwater signal

(device is interrogated acoustically) and returns with an underwater

acoustic reply. Sometimes abbreviated as "XPDR".

Turn Around

Time

A preset time delay, built into a transponder or responder, between

when a device is interrogated and when it replies. The delay is cali-

brated at the xponder to compensate for variations in receiver prop-

agation delays.

USBL Ultra Short BaseLine - A type of acoustic navigation system which

utilizes an array of receiving elements spaced very close together

(within inches). (As opposed to Long Baseline Systems)

Z The targets depth. Referenced from the plane of the hydrophone el-

ements or offset point to the target.

PRECAUTIONS

iii

A "NOTE" message is used to emphasize a certain operation or condition.

NOTE: "____________________________________________________________."

A "CAUTION" message is noted where an operational hazard to the equipment could exist.

C A U T I O N

A "WARNING" is used where an injurious or life threatening condition to an operator, in-

staller or troubleshooter could occur.

GENERAL INFORMATION

HP MULTIBEACON GENERAL INFORMATION

1-7

1. GENERAL INFORMATION

The various HP MultiBeacon configurations are shown in Table 1-1. The outline drawing of

the High Power-MultiBeacons (HP-MB) are shown in Figure 1-1 and Figure 1-2. This man-

ual covers the HP-MB Model 4360D-Series and its charger Model 4324C-V1661. The HP-

MB is a stand-alone Transponder or Responder. The HP-MB is factory configured for both

transponder and responder operation. When operating as a Responder the unit will de-

fault to a transponder if no key is present. Table 1-2 lists the interrogation frequencies

that can be factory set for the selected transmit frequency. The actual frequency the unit

is set to is written or marked on the pressure case label. The 4360D has a depth rating of

3000 meters. It is also available with a directional transducer, and/or remote transducer.

The Model 4360D is an integral transducer while the 4366D is a remote transducer unit.

The 4366D MultiBeacon is identical to the 4360D MultiBeacon except that it has a con-

nector to mate to its Remote Acoustic Projector. It does NOT have an integral (built-in)

acoustic projector. The Model 4366D-D is a remote head unit with a directional transduc-

er.

When used as a Transponder, the 4360D and 4366D will receive a signal between 17 and

22.5 kHz (typically) from an interrogation source. Once detected, a reply will be sent with

a frequency between 17-30 kHz (typically 24-28 kHz for a directional unit).

TABLE 1-1


1-8

When used as a Responder, the 4360D and 4366D will receive a (+) key pulse from an

umbilical wire attached to the unit. The unit will reply in the same manner as the tran-

sponder configuration 17-30 kHz (typically 24-28 kHz for a directional unit) or 13 or 16

kHz for the low frequency directional version 4360D-D-LF or 4366DA-D-LF.

The 4360D or 4366D replies with a power of 500 Watts providing a hemispherical beam

pattern with a nominal source level of 194 dB (ref 1 µPa @ 1 m). The 4360D-D also re-

plies with a power of 500 or 750 Watts, but has a directional transducer providing a beam

pattern of approximately ±30° from the vertical with a nominal source level of 199 or 202

dB (ref 1 µPa @ 1 m). Either beam pattern will be altered once the unit is mounted to a

structure. Sea trials should be performed to determine the best mounting position for the

particular application. The unit should be mounted so that there is a clear acoustic path

between the transducer and the shipboard tracking system hydrophone.

The Model 4360D normally contains rechargeable NiCad batteries but can be ordered with

alkaline primary cells (non-rechargeable) as an option. Lifetime is dependant on the use

and reply rate of the unit. In the Transponder configuration a receiver draws power from

the battery. This receiver is continuously powered on so that it can be interrogated

acoustically if the Responder key is not present. For example, if tracking an ROV and the

umbilical is severed, the Responder key will be disabled. After a 25-second time out the

unit can then be interrogated acoustically to resume tracking. In both the Transponder

and Responder modes, power is required for each reply, and more frequent replies accel-

erate battery drain and shorten operational life.

2. SPECIFICATIONS

The Model 4360D or 4366D HP-MultiBeacon has been tuned to a specific frequency. A

transformer has been designed to match the impedance of the transducing ceramic locat-

ed within the potted head. It also has a tuning coil that is wound to the specific frequency.

The transmit frequency is derived from a micro-controller whose program has been

burned into memory and cannot be changed in the field. Other parameters that are fixed

within the micro-controller program are the turn-around-time and lock-out time (resp). If

any of these parameters require changing the unit must be returned to ORE Offshore for

modification.

2.1 LIFETIME CALCULATIONS

1. The Nickel Cadmium (or NiCad) battery, when fully charged and in fresh con-

dition, will contain 21.6 Watt-hours of energy. (1.0A-hr X 12 Cells X 0.9V /

Cell) x 2 (two packs)

2. BATS Spread Spectrum Codes with Long NAV Pulse (16 ms) = 10 Watt-

seconds of energy per interrogation ((500 W nominally X .0165 Sec NAV) *

1.2 (xmit efficiency))

3. The quiescent (standby) power for the transponder receiver is .0022 Watts.

NOTE: In Responder Mode the micro-controller is on continuously at a current drain

of approximately 3 mA or 0.015 Watts.

BATTERY LIFE EQUATIONS/EXAMPLES

Battery life can vary depending on cell age, cell usage, temperature, etc. The following

equation provides an estimate of the life expectancy for a fresh battery pack at 20C

based on a 16 ms NAV output compatible with the BATS.

H = # of Hours of operation before battery is consumed

B = Starting Battery Energy (WattHrs)

X = Xmit Reply Energy (WattSeconds)

P = Interval between Pings (Seconds)

R = Continuous Receiver Current Drain (Watts)

Transponder or Responder Operation

H = B / (R + (X / P) )

H = 21.6 WattHours / (.0022 + ( 10 / 5 ) )

H = 10.7 hour operation @ a 5 second interrogation rate

With Standby time prior to interrogation…

S = Days of Standby operation (for Ni-Cads use a 0.5% per day self discharge)

H = ( ( B – (B * S * .005) ) - (R * S * 24 hrs) ) / ( R + ( X / P ) )

E.g., 5 day standby with a 3 second interrogation interval following…

H = ( ( 21.6 - ( 21.6 * 5 * .005) ) - (.0022 * 5 * 24) ) / (.0022 + (10 / 5) ) )

H = 10.4 Hrs operation after a 5 day standby

NOTE: The Self Discharge of a new Ni-cad battery is approximately 0.5% per day at

20C. In about 30 days the cell capacity will be reduced by 15%.

NOTE: A discharged battery should be fully charged after a period of 14-16 hours with

the current as supplied by the Model 4324C-V1661 Battery Charger (at the 300

mA output ) . Refer to the 4324C-V1661 Charger manual for proper operation.

3. OPERATION

This section contains the operation and configuration information necessary to use the HP

MultiBeacon. Prior to deployment check:

1. Battery Charge (for NiCad batteries only)

Be sure that the batteries are charged. See section 3.3.

* * * * * * * * * * * * * W A R N I N G * * * * * * * * * * * *

ALKALINE BATTERIES ARE NOT RECHARGEABLE. DO NOT

ATTEMPT TO CHARGE THESE CELLS. BE CERTAIN OF THE BATTERY TYPE

INSTALLED PRIOR TO CONNECTING TO THE CHARGER OR EXTERNAL SUPPLY.

2. Transponder/Responder Configuration

Be sure that the unit is configured for the type of operation and the frequency that

you intend to use. Insert shorting plug into end cap to turn unit on. Refer to Figure

3-1. The HP-MB will ping once after it has powered up. If the dummy plug is not

yellow on the end it may be an “open” dummy plug and will not work. Check pins 2

and 3 for continuity if in doubt.

3. Responder/Charging Configuration

Check that the HP-MB system is correctly wired. See Figure 3-2. When providing a

charging Voltage make sure the current is limited to 200 mA when battery Voltage

is fully charged at 16.2 VDC. For example, when charging from a 24VDC power

source add a 39 Ohm resistor in series with the supply.

RS = (24 V -16.2 V) / 0.20 Amps

RS = 39 Ω

Resistor Wattage = 5W minimum (15W to protect against a shorted battery)

4. External Power/Charging

The Model 4367D or 4368D can be powered from an 18VDC external source to pro-

vide unlimited operation. The 18V source also trickle charges the internal Ni-Cad

battery pack to maintain its full charge. If the external power drops out the battery

will take over. See Figure 3-3. The unit can either be triggered as a Responder or a

Transponder in this configuration. Requires an 18VDC power supply capable of 18

Watts output, a diode 50V 4A typically and a 75 Ohm Charge resistor at 5 Watts.

5. Responder Triggering

The Beacon can be triggered via an external source capable of providing a positive

going TTL pulse. The Beacon’s “Trigger Input” is an opto-coupler with an input im-

pedance of 500 . The “+” input connects to pin 4 of the end caps LPBH7 connector

and the “-“ connects to pin 5. Requires pigtail P/N: 0009900; Responder/Interface

Pigtail (LPIL7M – 2 FT). NOTE: When using the pigtail remember to short pins 2

and 3 to operate unit.

The HP MultiBeacon is activated by inserting a shorting plug in the interface connector lo-

cated on the bottom end cap. (The HP-MB will ping once after it has powered up.) Clean

and lightly lubricate the shorting plug to provide a good seal to its mating connector.

(Eliminates any seawater egress.)

C A U T I O N

Do not allow any silicone grease to contact the potted transducer.

Any silicone rubbed onto the transducer will result in reduced source level.


3-3

Check that the transducer is clean from all oils or grease. If cleaning is required, wash

with soap or detergent.

Operate the unit in air prior to deployment.

Responder Check:

In the responder mode, the transducer can be felt to "click" each time it is triggered. Set

up the trigger source (TTL Output) to interrogate unit about once every 2 seconds. Listen

for click or feel the pulse through the potted end.

Transponder Check:

When used with the Trackpoint USBL Systems it can be interrogated (acoustically trig-

gered) in air at a distance of about 1 meter between the USBL Transducer and the Tran-

sponder. Listen for click or feel the pulse through the potted end.

If it’s not possible to interrogate via the USBL system, the unit can be checked with an os-

cillator and oscilloscope and small speaker. Connect the oscilloscope to a wire wrapped

around the HP-MB projector transducer or the 4325/4335 remote transducer. Set the os-

cillator to the proper interrogation frequency and momentarily connect the speaker to

produce an interrogation. Hold the speaker close to the projector transducer. If the tran-

sponder replies, the electrical reply signal will be seen as pick-up on the wire wrapped

about the transducer on the HP-MB or 4325/4335 Acoustic Projector.

Mounting Considerations:

The HP-MB can be mounted to any suitable structural surface. Care should be taken, how-

ever, to isolate the aluminum pressure case from dissimilar metals, thus preventing elec-

trolysis. The HP-MB can be mounted in any position, but care should be exercised to

mount the projector transducer so that it has a direct acoustic path to the receiving appa-

ratus when in operation. For example, when mounting on a tow fish the Transponder can

be mounted on the tow arm (above the fish) so that it the beam is pointing back at the

vessel when under tow. Mounting of any transducer can change the beam characteristics

of that transducer. It is best to perform a shallow water test to assure proper operation

prior to final deployment.

3.2 EXTERNAL POWER SOURCES

The HP-MB can be operated with unrestricted battery life if connected to a +18 VDC

source capable of about 15 Watts. When so connected, the Ni-Cad battery will be kept in a

constant state of charge and the Beacon will operate off the external power. See Figure

3.2 for proper connections.

3.3 BATTERY CHARGING

(For beacons with Ni-Cad Battery pack) The HP-MB battery can be charged to capacity

in about 14 to 16 hours using the 4324C-V1661 Battery Charger at the 300 mA output.

Other power sources current limited to 300 mA can also be used. For Battery Charger In-

structions, see the 4324C-V1661 manual.

* * * * * * * * * * * * * W A R N I N G * * * * * * * * * * * *

NICAD CELLS MAY VENT WHEN BEING CHARGED. WHENEVER CHARGING,

REMOVE THE LOCKING STRIP ON END CAP. THIS WILL

ALLOW THE END CAP TO PUSH OUT AND VENTING TO OCCUR.

BE SURE TO REINSTALL THE LOCKING STRIP PRIOR TO DEPLOYING.

A continuous 14 to 16 hour charge will restore batteries to full storage capacity. See CAU-

TION below.

C A U T I O N

Do not allow the battery pack to become completely discharged to zero.

This may cause a reverse potential in one of the cells of the battery pack and

cause the battery to open circuit, whereby it will not hold or deliver any charge.

Spare or replacement cells are available from ORE if necessary. A properly maintained

NiCad battery will provide several hundred charge/discharge cycles before replacement is

necessary. To replace the battery pack cells refer to section 4.

3.4 POST DEPLOYMENT

After recovery, the unit should be cleaned and rinsed with fresh water to avoid salt

buildup and deterioration of mechanical parts. Deactivate the unit by removing the short-

ing plug. A visual check of the housing should be performed to detect any signs of dam-

age, excessive wear, corrosion, etc. If the HP-MB is not to be used again in the near fu-

ture, the unit should be turned off by removing the “shorted” dummy plug and replacing it

with a standard “open” dummy plug. If the unit is to be stored for a long period of time,

the batteries should be removed. See Maintenance procedures in Section 4.

4. MAINTENANCE

The HP-MultiBeacon requires minimal maintenance. Pre-deployment preparations and

checks, and post-deployment cleaning will fulfill most of the maintenance requirements.

The important tasks are battery replacement, 'O' ring care and maintenance, lubrication of

turn-on plug and general cleaning, inspection, and lubrication of operational elements.

4.1 DIS-ASSEMBLY

Deactivate the unit by removing the shorting plug located on the bottom end cap.

Remove the Purge Plug: (Nylon screw on connector end cap holds purge plug in

place with fiberglass retainer. Remove screw, retainer and then pull plug out with

pliers. NOTE: Be careful in case unit is pressurized. Unit can become pressurized in

event of a seal failure.)

Remove the Kynar retaining rod (White plastic rod) from the transducer end of the

housing. (Simply pull the rod out and away from the housing)

Gently pull the transducer end cap free from the housing. You may need to work it

side to side to get it started, but once the initial resistance is overcome the trans-

ducer should slide out easily. Part way through the removal, the o-ring will catch in

the groove previously occupied by the closure strip. A slight twisting and rocking ac-

tion while pulling will free the o-ring. Do not let the o-ring bunch up in the closure

strip groove. Dry any remaining wet parts.

The main electronics and battery pack assembly is connected to the transducer end

cap. If you are servicing o-rings, inspecting the connector end or replacing batteries,

then slide the transducer and electronics assembly out enough to disconnect the 6

pin cable from JP5 which goes to the end cap connector and the Pressure Sensor ca-

ble (also from the end cap) from JP2. The transducer end of the assembly can then

be pulled from the housing.

To remove the connector end cap pull the Kynar rod from the bottom connect-

or/pressure sensor end of the housing and then gently pull the end cap off.


4-2

4.2 BATTERY REPLACEMENT

The HP-MB uses a special dual welded pack of “AA” Ni-Cad (rechargeable) batteries. “AA”

Alkaline batteries can also be used for longer deployments.

* * * * * * * * * * * * * W A R N I N G * * * * * * * * * * * *

ALKALINE BATTERIES ARE NOT RECHARGEABLE. DO NOT ATTEMPT TO CHARGE THESE

CELLS. BE CERTAIN OF THE BATTERY TYPE INSTALLED PRIOR TO CONNECTING TO THE

CHARGER OR EXTERNAL SUPPLY.

BATTERY REPLACEMENT PROCEDURE

* * * * * * * * * * * * * W A R N I N G * * * * * * * * * * * *

IF THE UNDERWATER UNIT HAS BEEN DEPLOYED,

THERE IS THE POSSIBILITY OF INTERNAL PRESSURIZATION,

EXERCISE EXTREME CAUTION WHEN OPENING THE INSTRUMENT!

Open the instrument, refer to section 4.1. Separate the transducer end from the

housing by gently pulling them apart. Be careful not to scratch the housing throat

when pulling the assembly from the tube.

Disconnect the connector end cap cable (JP5) and pressure sensor cable (JP2) from

the electronics assembly. See Figure 4-2.

Remove the three screws that hold the brown phenolic end plate to the standoffs

around the battery pack.

Remove the plate and batteries from the unit. Properly dispose, of the old batteries.

Insert new battery pack.

Re-install the battery pack along with the brown phenolic end plate to the standoffs.

Re-assemble the instrument. Refer to section 4.2.


4-3

4.3 ASSEMBLY

Make certain that the O-rings and O-ring surfaces are clean and lightly greased (use

Parker O-Lube or silicone grease). REFER TO SECTION 4.5.

C A U T I O N



As the O-ring enters the housing bore, firm but gentle pressure must be applied to

seat the end cap fully against the housing.

Gently guide the connector end cap into the housing, taking care not to damage the

sealing surface of the housing or pinch any cables. Be sure to align the orientation

key while inserting it. While holding the end cap in place insert the Kynar retaining

rod back into the slot. Continue inserting the rod until it comes out the other end of

the slot.

After mating the end cap connector cables JP2 & JP5, gently guide the transducer

and electronics assembly into the housing, taking care not to damage the sealing

surface of the housing or pinch any cables. Be sure to align the orientation key to the

housing. While holding the end cap in place insert the Kynar retaining rod back into

the slot. Continue inserting the rod until it comes out the other end of the slot.

Purging & Vacuum Sealing: Purging unit with Nitrogen can prevent condensation.

Follow the procedure below.

EdgeTech/ORE Offshore releases are provided with a 5/16-inch diameter purging

port on the bottom end cap. The recommended procedure for preparation of the in-

struments atmosphere is as follows. The procedure assumes that the operator has a

vacuum pump, dry nitrogen cylinder and gauge all arranged on a manifold.

1. After verifying that all other (other than the purge port) o-ring seals have been

cleaned, lubricated and assembled.

2. Prepare the purge port plug for installation, the plug must be ready for immediate

insertion.

3. Insert a purge port vacuum adaptor and draw a -3 PSIG vacuum, do not exceed

-5 PSI. See note below.


4-4

4. Close the manifold valve to the instrument and allow the instrument to sit of for

15 minutes. Check the gauge afterwards and verify that the vacuum did not

change. This step is performed to detect gross o-ring problems.

5. Open the valve to the instrument’s purge port and:

* Backfill the housing with dry nitrogen gas, do not exceed +5 PSIG.

* Draw a -3 PSIG vacuum on the instrument, do not exceed -3PSI.

* Repeat this process four times.

* After drawing the final vacuum in this process, quickly insert the purging plug

before the -3 PSIG vacuum is lost.

* Secure the purge plug with the fiber glass retainer and nylon screw.

C A U T I O N

When purging the instrument, be careful not to draw more than -5 PSIG vacuum.

Exceeding this figure can damage the batteries which in turn can result in instr-

ument failure. If a purging set up is not available then place a desiccant pack

inside the housing to help reduce moisture.

* At this point it is good practice to perform an air acoustic test of the system. See

section 3.0.

4.4 BATTERY VOLTAGE CHECK

Remove dummy plug from end cap connector. Connect DVM to pins 1 (+) and pin 2

(-) of the end cap connector. A Ni-Cad pack should be 16 VDC if fully charged. An Al-

kaline pack should be about 18 VDC

4.5 O-RING CONSIDERATIONS

The end cap assemblies of the HP-MB use a standard o-ring to provide watertight integrity

to the electronics housing. Under normal usage, proper care and lubrication of the o-ring

should provide several years of usage. However, like the batteries, the o-ring is an inex-

pensive component, which is absolutely critical to the successful operation of the entire

system. It is good practice to replace the o-rings periodically, depending on frequency of

use. It is essential to inspect the o-rings and sealing surfaces before and after each de-

ployment.

Prepare the sealing surfaces for assembly by cleaning with a lint-free towel or swab, mois-

tened if needed with alcohol. Inspect for scratches or nicks which could impair the o-rings

ability to provide a seal. Apply a light coat of o-ring lubricant (typically O-Lube or silicone

based grease) to the housing bore and o-ring to facilitate insertion of the end cap. Make

sure the lubricant is compatible with Nitrile rubber. Inspect the o-ring for damage such as

tears, dimples or other defects in the rubber. Replace any o-ring that is questionable or

old. Lightly coat the o-ring with lubricant. Protect o-rings when stretching them over

large diameters (i.e., cover diameter with plastic sleeve).

There is an additional o-ring, which provides the watertight integrity to the housing. This

is located on the purge port on the connector end cap. Check and replace these o-rings

periodically.

C A U T I O N

Applying too much o-ring lubricant can compromise a seal!

Care of the O-Ring Seal

The o-ring seal is designed to keep the water at high ambient pressures from the internal

electronics. The HP-MB is designed to operate at pressures up to 4,350 PSI. Any hair-line

cracks or nicks in either the o-ring or the surfaces that it seals against can flood and de-

stroy the transponder. Each HP-MB unit is factory tested for leaks and is certified to meet

pressure depths at its full rating.

O-Ring Removal:

Remove the o-ring from its groove with the end of a soft, blunt object or stretch o-ring by

bunching up on one side and grabbing the loop. DO NOT USE HARD OR POINTED OB-

JECTS AS THEY MAY DAMAGE EITHER THE GROOVE OR THE O-RING. Slide the o-ring off

the unit taking care not to damage the ring or the circuit board edges. Wipe the o-ring

clean with a soft cloth and inspect both the inside and outside for any nicks or scratches.

Bending the o-ring while inspecting it will make any nicks or scratches more visible. Set

the o-ring aside in a clean area.


4-6

Pressure Canister:

Use a clean cloth or swab and clean the inside mating surface of the pressure canister.

Under a strong light, examine that the surface is free from any scratches or dirt.

End Cap Groove:

Use a clean cloth or swab and clean the o-ring groove. Inspect the surface for any nicks or

dirt.

O-Ring Installation:

Coat o-ring, back-up ring, o-ring groove and pressure canister surface with an o-ring lub-

ricant such as Parker O-Lube. Be careful when using a silicone based grease.

C A U T I O N



Carefully install the o-ring and back-up ring over the electronics boards so as not to

scratch the o-ring, and install the o-ring and back-up ring into their groove on the end

cap. The o-ring goes between the back-up ring and the high pressure.

The o-ring used in the HP-MB is manufactured from Nitrile or Buna N often referred to un-

der the trade names of Chemigum (Goodyear Tire & Rubber Co.), Paracril (Uniroyal),

Hycar (Goodrich Chemical Co.), Krynac (Polysar, Ltd.) and Ny Syn (Copolymer Rub-

ber & Chem. Corp.). The o-ring is a size 2-148 at a durometer of 70 with the following

dimensions:

Inside Diameter 2.737 .022" (56.82 + .500mm)

Cross Section Diameter .103 .003" (2.62 + .08mm)

The back-up ring is an 8-148 but at a durometer of 90.

The purge port on the connector end cap also has two o-rings. The size is 2-008-70.

O-ring and back-up ring replacements may be purchased directly from ORE Offshore.

4.6 GENERAL CLEANING AND INSPECTION

Whenever the unit has been recovered from a deployment, the unit should be cleaned and

rinsed with fresh water to avoid salt buildup and deterioration of mechanical parts. A vis-

ual check of the housing and release mechanism should be performed to detect any signs

of damage, excessive wear, corrosion, etc.

CARE OF CABLES

HP MULTIBEACON APPENDIX A

APPENDIX A - CARE OF CABLES

GENERAL NOTES:

Refer to caution below for disassembly of underwater cable connections.

C A U T I O N

Whenever underwater connectors are disassembled, or pressure cases

opened, water is drawn into the cavity formed by the separating parts. This

water, particularly salt water, enters as a fine spray and coats the electrical

contacts and other parts inside. It is extremely important to minimize this

buildup of moisture and salt, as it causes corrosion and voltage breakdown,

particularly on power leads, which have high voltages present. Therefore a

thorough cleaning is required, preferably immediately after opening the

parts. It is also helpful to rinse in fresh water and remove excess water from

parts prior to opening.

NOTES FOR PROPER CARE OF UNDERWATER CABLES:

DO Lubricate connectors before mating.

DO Keep cables free from dirt and salt.

DO Secure cables with tie wraps or tape so they won't work free.

DO Route cables where they won't get pinched or crushed by deployment

or moving machinery.

DO Periodically clean cable contacts with a cleaner/degreaser. Lubricate

with clean lubricant after cleaning.

DO Check cables with a VOM & megger periodically for electrical integrity.

DON'T Walk on cables.

DON'T Bend cables near the connectors.

DON'T Use damaged cables with bad or questionable contacts. They will

damage their mating half.

DON'T Hang things on cables.

DON'T Use cables for towing or pulling.

DON'T Bend the connectors when mating or disconnecting.

DON'T Clean cables with light hydrocarbon solvents (i.e. acetone, lacquer

thinner, paint thinner).

APPENDIX B

STATIC DISCHARGE

HP MULTIBEACON APPENDIX B

B-1

APPENDIX B - ELECTROSTATIC DISCHARGE (ESD)

The printed circuit boards within the Trackpoint MC1 console can be damaged by ESD.

Many of the electronic components are sensitive to electrostatic discharge. Some devices

can be damaged by a potential as low as 30Volts. People are a prime source of device-

damaging electrostatic potentials. Activities such as walking or working at a bench can

generate thousands of Volts of static potential. This charge is transmitted to a person’s

conductive perspiration layer, and when a charged person handles a static sensitive de-

vice, the component may be damaged by either direct or indirect discharge of the static

potential to the device.

NOTE: A person typically will not feel static discharge until the potential approaches 3500

Volts.

An electronic device exposed to static discharge may not be affected at all and will work

perfectly throughout a normal life cycle. It may, however, function normally for a while,

but because of degradation in the internal layers of the device, its life expectancy may be

reduced. The ESD event initiates a device weakness that degrades and causes failure with

continued use.

RULE 1: Assume all electronic (solid state) components are sensitive to ESD damage.

RULE 2: Never touch a sensitive component or assembly unless properly grounded. When

handling circuit assemblies or when working with them, always use the appropriate

grounding procedure: wrist strap connected to ground or heelstrap with a grounded dissi-

pative floormat.

RULE 3: Never transport, store, or handle sensitive components or assemblies except in a

static-safe environment. Use static shielding bags when transporting circuit boards.

If a grounded dissipative floor-mat or wrist-strap is not available then at the very least,

when swapping out Printed Circuit Boards, discharge yourself to the chassis of the unit.

Lift out circuit board from chassis and immediately put it on a conductive surface. Remove

the new circuit board from its anti-static bag only after grasping the anti-static bag (with

PCB inside) and the chassis. Remove board and place directly inside chassis. Put replaced

board in the spare’s anti-static bag for transport/storage.

2.0 OPERATION AND MAINTENANCE

2.1 GENERAL

The Model 4324C-V1661 is a desk top NiCad battery charger. It is designed to

work at 120 or 220 Volts AC 50/60Hz This is manually selected (see Figure 1).

This V1661 charger is compatible with the 436XD series Multibeacons only.

The 4324C-V1661 is a dual output whose current is limited to 110 mA or 300 mA

but will reduce output to about 40 mA as battery Voltage approaches a full charge.

The 4324C-V1661 will fully charge a dual battery pack (12 Nicad cells in series) in

14-16 hours at the 300 mA switch setting. The charger can be left trickle charging

the battery at this low current (40 mA) almost indefinitely.

The 4324C has internal short circuit protection, however, it is not recommended to

maintain a short for any extended period of time.

2.2 CONFIGURING THE CHARGER FOR SINGLE INTERNAL BATTERY PACK

Select the proper AC input voltage, 100/120/220 VAC, reference Figure 1 for de-

tails.

Connect the pigtail (LPIL7M) to the terminal screw on the charger. The red lead of

the pigtail goes to the plus screw terminal, and the black lead goes to the minus

screw terminal.

Plug the other end of the connector into the Beacon.

2.3 MAINTENANCE

A quick test to see if the charger is operating is to put a (VOM) Volt/Ohm Meter

across the plus and minus output screw terminals and measure approximately 19

volts +1 volt.

The 4324C-V1661 has two internal in-line fuses. If there is no output as tested in

2.41, check to see if the fuses are open, reference Figure 1.
