Introduction

Supply conditions

The following supply conditions are applicable to standard Simrad PI44 deliveries and associated optional equipment.

Equipment responsibility

The shipyard performing the installation and/or dealer becomes fully responsible for the equipment upon receipt unless otherwise stated in the contract. The duration of responsibility includes:

• The period of time the equipment is stored locally before installation.

• During the entire installation process.

• While commissioning the equipment.

• The period of time between commissioning and the final

acceptance of the equipment by the end user (normally the owner of the vessel which the equipment has been installed).

The Simrad PI44 system guarantee period (as specified in the contract) begins when the acceptance documents have been signed unless other arrangements have been made in the contract.

Receipt, unpacking and storage

Upon accepting shipment of the equipment, the shipyard and/or the dealer should ensure that the delivery is complete and inspect each shipping container for evidence of physical damage. If this inspection reveals any indication of crushing, dropping, immersion in water or any other form of damage, the recipient should request that a representative from the company used to transport the equipment be present during unpacking.

All equipment should be inspected for physical damage, i.e. broken controls and indicators, dents, scratches etc. during unpacking. If any damage to the equipment is discovered, the recipient should notify both the transportation company and Simrad so that Simrad can arrange for replacement or repair of the damaged equipment.

Once unpacked, the equipment must be stored in a controlled environment with an atmosphere free of corrosive agents, excessive humidity or temperature extremes. The equipment must be covered to protect it from dust and other forms of contamination when stored.

851-165101 / Rev.A

Simrad PI44

General installation requirements

Responsibility and approval

The Simrad PI44’s hydrophone and echo sounder i nstallation must be approved on a case-by-case basis with regard to the vessel’s national registry and corresponding maritime authority. The shipowner and shipyard performing the installation are responsible for obtaining installation approval.

Environmental requirements

All equipment, unless otherwise specified, must be protected from temperature extremes and excessive humidity.

Compass deviation

Once the installation is complete, the vessel must be swung with the PI44 system in both the operative and inoperative modes. The shipowner and captain are responsible for updating the deviation table accordingly with regard to the vessel’s national registry and corresponding maritime authority.

Noise sources

The vessel’s hull, rudder(s) and propeller(s) should be thoroughly inspected in dry dock prior to installation. Roughness below the water-line deformities in the shell plating and protruding obstacles can create underwater noise. These sources of turbulence must be smoothed or removed as best as possible. It is especially important that the propeller(s) is not pitted or damaged.

Dry docking

Make sure that ample clearance under the hydrophone and e cho sounder transducer is provided when dry docking the vessel. Avoid locating supporting blocks or structures in the vicinity of this equipment.

Note: The location of the hydrophone and echo sounder transducer

must be noted on the vessel’s docking plan for future reference.

Wiring

The cables from the wheelhouse to the hydrophone and echo sounder transducer must be supported and protected along its entire length using conduits and/or cable trays. Note that the cables must not be installed in the vicinity of high-power supplies and cables, antenna cables or other possible sources of interferences.

851-165101 / Rev.A

Introduction

Equipment handling

The units may be supplied as spare parts, or as parts of a delivery.

Transportation

Unless otherwise stated in the accompanying documentation, electronic, electro-mechanical and mechanical units supplied by Simrad can be transported using all methods approved for delicate equipment; (by road, rail, air or sea). The units are to be transported in accordance with general or specific i nstructions for the appropriate unit(s), using pallets, transport cases, or carton boxes as appropriate.

Note: Special local restrictions concerning air transportation may be

applied to units containing certain types of batteries. The units should be checked and the regulations investigated by the packer/shipper before the unit is dispatched.

All local transportation must be carried out according to the same specifications as for the initial delivery. In general, all units must be handled with care. The carton or case containing the equipment must be kept dry at all times, and must be sheltered from the weather. It must not be subjected to shocks, excessive vibration or other rough handling.

The carton or case will normally be marked with text or symbols indicating which way up it is to be placed. Follow any instructions given and ensure the case is always placed with its “top” uppermost.

The carton or case must not be used for any purpose for which it was not intended (step, table, etc.), and in the absence of other information, no other cartons or cases must be stacked on top of it.

Lifting

A heavy crate will normally be marked with its weight, and the weights of other cartons or crates will normally be entered on the packing list.

851-165101 / Rev.A

• Always check the weight of a crate before attempting to lift it.

• Always use lifting apparatus that is certified for the load.

Simrad PI44

Heavy units may be equipped with lifting lugs for transportation by crane within the workshop or installation area. Before a crane is used, check:

• The applicable weight certificate for the crane.

• The security of the lifting lugs.

Ensure that all available lifting lugs are used. Ensure the unit remains under control during the operation to avoid damage to the unit, equipment or personnel.

Heavy units may be transported using a fork-lift truck. Special attention must then be paid to the position of the unit’s centre of gravity. The units must be properly secured to the truck.

Initial preservation

When a system, a unit or a spare part has been delivered to the customer, it may be subject to long-time storage prior to installation and use. During this storage period, certain specifications must be met.

The equipment must be preserved and stored in such a way that it does not constitute any danger to health, environment or personal injury.

Specific specifications are presented below.

→ For further information about storage, refer to page 12. → For further information about re-packing, refer to page 15. → For further information about temperature protection, refer to

page 17.

Preserving the original packing crate

1 The equipment must be stored in its original transportation

crate.

2 Ensure that the units are clearly separated in the shelves

and that each unit is easily identifiable.

3 The crate must not be used for any purpose for which it

was not intended (eg. work platform etc.).

4 The crates must not be placed on top of each other, unless

specific markings permit this.

5 The crates must not be placed directly on a dirt-floor. 6 Do not open the crate for inspection unless special

circumstances permit so.

- “Special circumstances” may be suspected damage to the crate and its content, or inspections by civil authorities.

851-165101 / Rev.A

Introduction

- If any units are damaged, prepare an inspection report stating the condition of the unit and actions taken. Describe the damage and collect photographic evidence if possible. Re-preserve the equipment.

- If the units are not damaged, check the humidity absorbing material. If required, dry or replace the bags, then repack the unit(s) according to the packing instructions.

7 If the crate has been opened, make sure that is it closed

and sealed after the inspection.

- Use the original packing material as far as possible.

→ Refer to information on page 15.

Ambient temperature and humidity during storage

1 The storage room/area must be dry, with a non-condensing

atmosphere. It must be free from corrosive agents.

2 The storage area’s mean temperature must not be lower

than -30°C, and not warmer than +70° C.

- If other limitations apply, the crates will be marked accordingly.

Note: Transducers must not be stored in temperatures below -20°C, or

higher than +60°C.

3 The crate must not be exposed to moisture from fluid

leakages.

4 The crate must not be exposed to direct sunlight or

excessive warmth from heaters.

Shock and vibration during storage

1 The crate must not be subjected to excessive shock and

vibration.

851-165101 / Rev.A

ESD precautions during storage

→ Refer to the information on page 16.

If the unit contains normal batteries, these may have been disconnected/isolated before the unit was packed. These must only be reconnected before the installation starts. Units containing batteries are marked.

Simrad PI44

Caution: Units containing lithium or alkaline batteries must be

handled separately and with care. Such units are marked accordingly. Do not attempt to recharge such batteries, open them or dispose of them by incineration. Refer to the applicable product data sheets.

Inspection and unpacking

An inspection must be carried out immediately after the unit(s) have arrived at their destination.

• Check all wooden or cardboard boxes, plastic bags and pallets for physical damage. Look for signs of dropping, immersion in water or other mishandling.

• If damage is detected externally, you will have to open the packaging to check the contents.

- Request a representative of the carrier to be present while

the carton is opened, so any transportation damage can be identified.

• If any units are damaged, prepare an inspection report stating the condition of the unit and actions taken. Describe the damage and collect photographic evidence if possible. Send the inspection report to Simrad as soon as possible.

• If the units are not damaged, check the humidity absorbing material. If required, dry or replace the bags, then repack the unit(s) according to the packing instructions.

Inspection and unpacking: General procedure

Normal precautions for the handling, transportation and storage of fragile electronic equipment must be undertaken.

Note: If the unit is not to be prepared for immediate use, you may

consider storing it unopened in its original packing material. However, it may be useful to open the case to check its contents for damage and retrieve any accompanying documentation.

• Check the carton before opening it to ensure it shows no signs of dropping, immersion in water or other mishandling.

- If the carton shows signs of such damage, refer to the

paragraph covering Inspection on receipt.

851-165101 / Rev.A

Introduction

• Place the carton on a stable work bench or on the floor with the top of the carton uppermost.

• In the absence of other instructions, always open the top of the carton first. The contents will normally have been lowered into the carton from above, so this will usually be the easiest route to follow.

- Care must be used when opening the carton to ensure the

contents are not damaged.

Caution: Do not use a knife to open cardboard cartons - the

contents may lie close to the surface, and may be damaged by the blade.

• If the carton has been closed using staples, remove the staples from the carton as you open it. This will reduce the possibilities of scratch injury to yourself and damage to the contents.

• If a wooden crate has been closed using screws, always remove them using a screw-driver. Do not attempt to prise the lid off with a crow-bar or similar.

• Once the carton is open, carefully remove all loose packing and insulation material. Check for manuals and other documents that may have been added to the carton during packing, and put these to one side. Check also for special tools, door keys etc.

Unpacking electronic and electro-mechanical units

Caution: Beware of the dangers of Electro-Static Discharge

(ESD) both to yourself and to the equipment, when handling electronic units and components. Refer to the precautions starting on page 16.

Electronic and electro-mechanical units will normally be wrapped in a clear plastic bag. Lift the unit, in its bag, out of the carton and place it in a stable position on the floor/work bench.

Inspect the unit for damage before opening the plastic bag.

Note: Cables must never be used as carrying handles or lifting points.

851-165101 / Rev.A

Simrad PI44

Note: Do not break the seal to open a circuit board package before the

board is to be used. If the board package is returned to the manufacturers with the seal broken, the contents will be assumed to have been used and the customer will be billed accordingly.

Assuming all is well, open the bag and remove the unit. Open the unit and check inside. Remove any packing and

desiccant material that may be inside.

Unpacking mechanical units

Mechanical units may be heavy. Using a suitably certified lifting apparatus, lift the unit out of the crate and place it in a stable position on the floor/work bench.

Inspect the unit for damage and remove any packing material that may be inside the unit.

Unpacking transducers

Transducers may be supplied mounted to a hull unit (if any), or packed separately. Crates are normally identified by the order number and the serial number.

The transducer face must be protected by a rigid, padded cover (e.g. a wooden box lined with foam rubber) all the time it is exposed to the risk of physical damage.

Note: Once the units are unpacked, great care must be taken to ensure

that transducers and cabling are not exposed to any mechanical stress.

Re-packaging

If the unit is not to be installed immediately, re-pack it in its original packing material to prevent damage in the intervening period.

→ Refer to the information on page 15.

Pre-installation storage

The equipment should be stored in its original transportation crate until ready for installation. The crate must not be used for any purpose for which it was not intended (eg. work platform etc.).

851-165101 / Rev.A

Introduction

Once unpacked, the equipment must be kept in a dry, non condensing atmosphere, free from corrosive agents and isolated from sources of vibration.

Note: Do not break the seal to open a circuit board package before the

board is to be used. If the board package is returned to the manufacturers with the seal broken, the contents will be assumed to have been used and the customer will be billed accordingly.

The unit must be installed in its intended operating position as soon as possible after unpacking.

If the unit contains normal batteries, these may have been disconnected/isolated before the unit was packed. These must then be reconnected during the installation procedure. Units containing batteries are marked.

Caution: Units containing lithium or alkaline batteries must be

After use storage

If a unit is removed from its operating location and placed into storage, it must be properly cleaned and prepared before packing.

Cleaning cabinets

If a cabinet has been exposed to salt atmosphere while it was in use, it must be thoroughly cleaned both i nternally and externally to prevent corrosion.

• Wipe the cabinet externally using a damp cloth and a little detergent. Do not use excessive amounts of water as the unit may not be water tight. On completion, dry the unit thoroughly.

851-165101 / Rev.A

• All surfaces must be inspected for signs of corrosion, eg. flaking/bubbling paint, stains etc. Damaged or suspect areas must be cleaned, prepared and preserved using the correct preservation mediums for the unit. The mediums to be used will usually be defined in the units’ maintenance manual.

Simrad PI44

• Open the unit, and using a vacuum cleaner, remove all dust etc. from the unit. Great care must be taken to ensure the circuit boards and modules are not damaged in the process.

Mechanical units

If a mechanical unit may have been exposed to a salt atmosphere while it was in use, it must be thoroughly cleaned both internally and externally to prevent corrosion.

• If the construction materials and type of unit permits, wash the unit using a high-pressure hose and copious amounts of fresh water.

Examples:

- The lower parts of hull units (outside the hull)

- Subsea units

• Ensure that all traces of mud and marine growth are removed. Use a wooden or plastic scraper to remove persistent growth, barnacles etc. On completion, dry the unit thoroughly.

Caution: Do not use a high pressure hose in the vicinity of cables

or transducers. Do not use sharp or metal tools on a transducer face.

• If the materials or type of unit prevents the use of a high-pressure hose, wipe the unit using a cloth dampened with water containing a little detergent.

Examples:

- The upper parts of hull units (inside the hull)

- Hydraulic systems

• Do not use excessive amounts of water as some components on the unit may not be water tight. Wipe off the detergent with a damp cloth, then dry the unit thoroughly.

• All surfaces must be inspected for signs of corrosion, eg. flaking/bubbling paint, stains etc. Damaged or suspect areas must be cleaned, prepared and preserved using the correct preservation mediums. The mediums to be used will normally be defined in the unit’s maintenance manual.

Cables

Wipe clean all exposed cables, and check for damage. If a cable shows signs of wear or ageing, contact Simrad for advice.

851-165101 / Rev.A

Introduction

Internal batteries

If the unit contains batteries, these may discharge slowly during storage. If the unit is to be stored for an extended period, disconnect or remove all internal batteries.

A suitable piece of insulating material can be placed between the battery and the electrical contacts to prevent electrical discharge. The battery can then remain in the unit, reducing the risk of it being misplaced during the storage period.

Caution: Units containing lithium or alkaline batteries must be

Dehumidifier

Place a suitably sized bag of desiccant material (silica gel or similar) into the unit to keep the electronic components as dry as possible.

Coatings

Spray the unit externally with a corrosion inhibitor (e.g. a light oil) before packing.

Re-packing

The unit should be stored and transported in its original packing material and/or crate. In the event that this material is not available, proceed as follows:

• Small units must be protected from damp by being placed within a plastic bag at least 0.15 mm thick. An appropriate quantity of desiccant material should be placed inside this bag, and the bag sealed. The sealed unit must then be placed in an appropriate carton or crate, and supported in the container by appropriate shock-absorbing insulation (polystyrene foam chips etc.).

851-165101 / Rev.A

• Large units must be placed in a suitable cardboard box or wooden crate. The unit must be protected against physical damage by means of shock-absorbing insulation mats. The box must be clearly marked with its contents, and must be stored in a dry and dust-free area.

Simrad PI44

ESD precautions

Electro-Static Discharge (ESD) is the transfer of an electrostatic charge between two bodies at different electrostatic potentials, caused either by direct contact or induction by an electrostatic field.

The passing of a charge through an electronic device can cause localised overheating, and it can also “puncture” insulating layers within the structure of the device. This may deposit a conductive residue of the vaporised metal on the device, and thus create a short circuit. This may result in a catastrophic failure, or degraded performance of the device.

Sensitive electronic equipment must be transported and stored in protective packing bags, boxes and cabinets. The equipment must NOT be transported or stored close to strong electrostatic, electro-magnetic or radioactive fields.

If it is necessary to open and touch the electronics inside the boxes/cabinets, then the following precautions MUST be taken:

• The working area must be covered by an approved conductive service mat that has a resistance of between 50kΩ and2MΩ, and is connected directly to a reliable earth point via its earthing cord.

• The service personnel involved must wear a wrist-band in direct contact with the skin, connected to the service mat.

• Printed circuit boards and other components should be placed on the conductive service mat during installation, maintenance etc.

Caution: If, for any reason, it is necessary to move the circuit

board or components from the conductive service mat, they must be placed in an approved anti-static transportation container (e.g. static shielding bag) before transportation.

• During installation and servicing, all electrical equipment (soldering irons, test equipment etc.) must be earthed.

851-165101 / Rev.A

Temperature protection

If the unit must be protected against extremes of temperature, the carton/crate must be lined on all walls, base and lid with 5 cm thick polyurethane or polystyrene foam.

These units will be identified as delicate i n the applicable documentation.

The package must then be clearly marked:

Note: Must not be transported or stored in temperatures

below -5 degrees Celsius.

Other units can normally be stored in temperatures between -30° C and +70° C, refer t o the system’s technical specifications for details.

Introduction

Transducers must not be stored in temperatures below -20°C and above +60°C.

2 TRANSDUCER INSTALLATION

Purpose

Due to the fact that several transducer types may be used with the PI44 system, you will need to read the installation manual for the chosen transducer. The information provided in this chapter will only provide general information. Refer to the installation manuals provided with the transducers for more specific information.

The PI44 can be used with maximum two transducers simultanously, one low frequency (38 or 50 kHz) and one high frequency (200 kHz). We recommend that any one of the following transducers are used:

• Simrad 38-200 Combi C (dual frequency)

• Simrad 38-200 Combi D (dual frequency)

• Simrad 38-200 Combi W (dual frequency, wide beam)

Other transducers may also be used. Budget transducers designed for leasure crafts are however not recommended for professional fishery applications.
