SF200 COMPONENTS AND DEPLOYMENT
SF200 features
The SF200 is the worlds’ first sensor based feeding control system for shrimp farmers. Thesystem uses passive acoustics to identify shrimp feeding activity and then uses that information tocontrol temporal feed delivery via the AQ1 Sonic© feeding algorithm. The Sonic© algorithmensures feed delivered matches shrimp appetite so that all animals are fed fully without waste 24hours a day if required.
The system features:
• A hydrophone sensor that determines feeding activity by measuring shrimp “feeding”sounds
• Sonic© feeding algorithms to control feeding rates• Built to high grade (IP66) standards and easy to maintain• Can support a variety of feeders• Can support a variety of environmental sensors• Automates feeding delivery 24/7• Improves FCR & Growth• Replaces feed trays• Minimises labour• Eliminates waste feed• Reduces size variation at harvest

water velocity). The slow fouling rubber probe comes with electrically shielded cable and requiresno calibration – it should be checked routinely and cleared/wiped of biofouling as needed.

Hydrophone Deployment Considerations
• Ensure the hydrophone is not entangled at deployment (entanglement may cause excess noisedue to rubbing that interferes with system operation).
• The Omnidirectional hydrophone samples an area within the feed zone.• The location of the hydrophone must be “downstream” from the centre of the feeding zone –
as determined by water flow direction created by the aerator(s).• Avoid placing hydrophone cable near or traversing mains power cable, or attached to
pontoon/jetty or autofeeder to minimise any potential electrical or sound interference.• If running the hydrophone cable across pond service roads, use a buried conduit.

Deployment Requirements
● Distance of hydrophone(s) to nearest aerator must be >15m● Distance of aerator(s) to edge of feeding zone must be > 10m● Radius of feed zone must be sufficient surface area meet feed demand of biomass

site specification form.. Also the radius of feed zone should be greater than the radius ofthe hydrophone detection zone under most operational conditions.
Consideration for ponds with high water velocities
Under certain circumstances – if the water current is high then it is recommended to calculate thebest hydrophone position based on the sinking speed of pellet and the estimated water velocity.When pellets hit the water, they are moved by the pond current. The hydrophone should be placedon the pond in approximately the location where the majority of pellets will reach the bottom of thepond.
How to calculate where the majority of pellets land on pond bottom in high watervelocity
1. First calculate how long the pellets take to sink to the bottom with no current. If the depth ofthe pond is 150cm, and the pellets sink at 10cm/s, the pellets take 15 seconds to reach thebottom of the pond. (divide pond depth by sink rate in seconds).
2. In 15 seconds, how far will the current push the pellets? If the current is 22cm/s, then thepellet will be pushed approximately 3.3m. (multiply current speed by sink time).
Feeder type and number per pond
The number of suitable feeders (bank or centrally located) and deployment method is specific tothe pond size/configuration, species grown and biomass (consult AQ1).
General Considerations (species dependant)L. vannamei: 5600,000 shrimp per feeder
● no more than 1500 shrimp/m² maximum density in the feeding area.P. monodon: 2300,000 shrimp per feeder
● No more than 500 shrimp/m² maximum density in the feeding area.

IMPORTANT: All mains power (110480VAC) connections and installation MUST be carriedout by a qualified electrician.
SF200 Routine Service Requirements
SF200 Controller● Check red LED inside SF200 controller
o ON (intermittent flashing) system functioningo ON (solid) system is in reboot mode please wait 2 minutes and if still ON (solid)
please call your local AQ1 representative.
Hopper● Make sure pellets can flow freely with no obstruction in hopper at exit point into spreader
Hopper Motors● Test motor function with TEST button on the SF200 controller. All motors connected to the
SF200 controller will spin for as long as the button is held depressed up to a maximum of300 seconds. It is recommended that the operator disables the feeder not under test at thejunction box when testing motor functions.
● Get a qualified electrician to check wiring and motor condition if the system is still notoperating correctly.
Hydrophone● Monitor biofouling on the hydrophone initially once per week and wipe clean with a non
abrasive cloth or light brush as required to keep rubber surface clean. Adjust frequency ofcleaning based on the rate of biofouling experienced. Biofouling rates will vary from pondto pond, site to site and seasonally.
● When retrieving a hydrophone from a pond please do not use undue force as the cable canbreak. If the unit becomes entangled the obstruction will need to be removed prior toretrieval.
● Upon redeployment check position is suitable as per deployment section 3.1 and make surethe hydrophone is repositioned in the same spot after cleaning
● When the hydrophone cable is resting on the ground it must be located in a zero traffic pointand can’t move or rub on the ground.
● Stop the hydrophone cable from flapping in the wind at the pole supporting the SF200 bytying the hydrophone cable to the pole using cable ties,
● Coil any spare hydrophone cable at the base of the SF200 pole and use a cable tie to lock itinto a coil, and let it lie on the ground where hopefully it won’t get disturbed. (Reverse onehalf of the coil before cable tying it– this reduces the possibility of electrical interferencegetting coupled in through the coil).
● The hydrophone cable must not touch the jetty or other object in the pond because it picksup vibration from the Hopper motor and wind causing the cable to tap. The cable must bepositioned on the bottom of the pond and be isolated from these sources of physical noiseinterference.

SF200 Hardware Deployment Guide
● No rope should flap anywhere underwater against the hydrophone cable.● The connection of the hydrophone to its rubber weight anchor must clamp firmly and not be
able to move, rub or bump
Mains Power Supply● Check with a multimeter that the low voltage 15VDC supply is present and the unit is
turned ON.
● Get a certified electrician to check AC is ON and stable.
SF200 storing considerations
Storing the SF200 Controller
● The SF200 controller should be switched off at the switch on the unit first, and then themain power switch.
● Check the oring seals on the door of the unit are free of debris and the oring is in aserviceable condition.
● The door of the unit should be fully closed and latched with the key supplied● Place a plastic UV rated bag over the antenna and loosely tie it closed at the bottom with a
bag tie or similar.● For long term decommissioning it is recommended that the hopper is removed to a covered
location.
Hopper● Turn power to the hopper off at the switchbox● Empty hopper and wipe out interior with a rag.● Dislodge any pellets caught between doser and spreader.● Install a canvas shroud around feeder motor area to help minimise rain falling & water
splashing onto the spinner motor.
Hydrophone care and storage
Cleaning and storing the Hydrophones● Care should be taken when cleaning the hydrophone as it is a delicate device and it can
become damaged if it is dropped or subjected to any undue knocks.
©AQ1 Systems Pty Ltd 2013 page 14
SF200 Hardware Deployment Guide
● The hydrophone should be removed from the pond and cleaned with warm soapy waterusing a non abrasive rag. This includes the cable as well. The cable and hydrophone shouldthen be rinsed in fresh water and placed in warm dry place.
● The hydrophone and its cable should be inspected for damage as cuts in the cable willrender the device unserviceable as will cuts on the face of the hydrophone itself thatpenetrate to the ceramic under layer. If in doubt please send images of the damage to AQ1Systems for advice.
● After cleaning the cable should be loosely rolled over your arm taking care not to twist thecable.
● Place a bag tie around the cable and tie it● Place a small piece of bubble wrap, foam or piece of rag around the hydrophone so as to
protect it from knocks and secure it with some masking tape● Place the unit in a dry vermin free environment while not in use.
