ORCA Sonar System
Overview
3
Benets
• Improved efficiency and control of the thickener process
• Fully automated plant systems with reliable interface level monitoring
• Advanced warning of process upset or hydraulic in-balance
• Reduced maintenance with automatic cleaning mechanism warranty (no blades to replace)
• Reduced site operational costs significantly with improved process & extraction control
• Improved health and safety on site (no manual dips required).
Principle of Operation
The ORCA Sonar Series transducer emits a high powered low frequency sonar pulse, which is reflected
from the interface density selected. The reflected signal is processed using specially developed software
algorithms that eliminate unwanted densities and stratified layers, allowing measurement of Bed or RAS
levels. It can be calibrated to measure lighter densities such as the hindered / free settling layer & floc or one
of the outputs could be used for a “Clarity” output, similar to a basic turbidity transmitter measuring solids in
suspension. The unit can include two outputs to measure two different interfaces simultaneously.
Function
The ORCA Series Sonar, sludge blanket and interface controller, consists of a microprocessor based
transmitter, with easy menu driven programming via keypad, PC or 3G modem. The ORCA controller works
together with appropriate sonar transducer and transducer cleaning mechanism.
Features
• Dual independent analogue outputs to track two
different interfaces, or clarity simultaneously, with
the one sonar sensor
• Easy to use pre-set calibrations to track specic
density interfaces, eg: oc / uff layer, Bed
• Industrial scum cleaning mechanisms that do not
require maintenance
• Control room graphics of tanks and interfaces via
GosHawk II
• Wide range of communications: Modbus, HART,
Foundation Fieldbus, DeviceNet, Probus DP and
Probus PA
• 3G remote support capability for calibration,
commissioning or technical back-up
• 3 programmable relays.

Impact Plate Mounting Connection
The top of the Impact Plate has 3 x 7mm bolt holes
which can be secured to an angle iron or equivalent
bracket. There is also a M25 (1.5”) threaded
connection for a mounting pole connection. The
Impact Plate is designed to swing parallel with the
counter weights. The surface sweeper must come
in contact with the legs of the Impact Plate which
swings the bracket lifting the transducer out of the
liquid. When the sweeper has cleared, it will drop
back in and use the counter weights to re-center. The
force of the movement will clear the sensor face of
any build up

ORCA Transmitter – Mounting Requirements
Select a suitable mounting position, preferably not in
direct sunlight. If necessary utilize a sunshade.
Observe the maximum and minimum temperature
specification.
Do not mount the sonar transmitter near high sources
of EMF, such as motor starters, variable speed drives
or 3 phase cables. Avoid mounting in high vibration
areas, or use rubber absorption mounts.
Be careful when removing the cable and compression
glands.
Installation Guide
Sonar Transducer – Mounting Requirements
The transducer should be half submerged in the liquid
and the transducer face must always be submerged.
Wrap cable entry and lower connection cable with
Teflon tape
Round Tanks – Centre Feedwell
Mount the sonar transducer and cleaning mechanism,
approximately one third radius between the outside
tank wall and the feedwell. This is the same whether it
is a moving or fixed bridge installation.
Do not mount near high infeed turbulence.
Choose a site installation where the infeed is least
disturbed.
High Level
20mA
0.500m
Low Level
4mA
X.xxm
Blanking /
non-measured
zone
1/2 Submerged
1/3 Radius
Rectangular Tanks – End Feed
Mount the sonar transducer and cleaning mechanism
away from high infeed turbulence. A clearance of
700mm from the side wall.
Do not mount directly over scraper, chain
mechanisms. Choose a site installation where the
infeed is least disturbed.
Ball oat
Mount the floating sonar transducer and cleaning
mechanism as close as practicable to the launders.
Mount at least 1.00 metres from side walls. Ensure
alignment guides are installed on the mounting
bracket for decanter ranges above 500mm.
Impact Plates
Leave an extra 2 turns of cable where the transducer
connects to the actuator to minimise stress and wear
on the cable (see Impact Plate Assembly).

Note 1: Calculations based on:
4.0 Amps max actuator current and;
4.0 Volts drop across max cable length ( 2 wires)
Note 1: Note 2: Maximum terminal capacity is 1.5mm, which limits 16AWG cable to35m.
Note 3: For long cable runs, use 16 AWG to local junction box, then extend using 10-14 AWG.
Note 4: Also required: 3-wire cable for feedback potentiometer, 0.5mm - 1.0mm.

Set the BaudRate and the DeviceNet Address in
Sultan
Factory defaults of baudrate and FBusAdds are
125kbps and 63 in a Sultan unit with DeviceNet
CommType. To modify these values follow the
instructions below.
1. Go to the Output Adjustment menu
2. Use the Up and Down push buttons to reach the
CommType parameter
3. Make sure that the CommType is set to DeviceNet
4. Press the CAL button twice. If you see DeviceID do
not modify this parameter.
5. Use the Down push button to reach the BaudRate
parameter
6. The default value for the BaudRate is 125kpbs.
Press CAL button and use the Up and Down push
buttons to modify this value
7. Press CAL button when finished
8. Use the Down push button to reach the FBusAdds.
The default value of the Fieldbus Address is 63.
Press CAL button and use the Up and Down push
buttons to modify this value
9. Press CAL button again when finished

Probus DP
Set the Profibus Address in Sultan
Factory defaults of FBusAdds is 126 in a Sultan unit
with Profibus CommType. To modify this value follow
the instruction below:
1. Go to the Output Adj menu
2. Use the Up and Down push buttons to reach the
CommType parameter
3. Make sure that the CommType is set to
Profibus DP
Failed ~~~~~~ Search 0 Echo Cfm : 1 =
True, 0 = False
Echo R : 1 =
True, 0 = False
4. Press the CAL button twice - If you see DeviceID
do not modify this parameter
6. Use the Down push button to reach the BaudRate
parameter. Note this cannot be modified
8. Use the Down push button to reach the FBusAdds.
The default value of the Fieldbus Address is 126.
Press CAL button and use the Up and Down push
buttons to modify this value
9. Press CAL button again when finish.

Powering The Unit
When power is applied the unit will start up automatically. It will scroll through its boot diagnostics and display
the serial numbers, software version and model types for the amplifier and transducer
The unit will display its default operating screen depending on the App Type selected (default: Bed) on the
top line and a distance or % on the bottom line. The distance will be the programmed display mode (Default:
Level).
The unit will re-scan for the measurement whenever it is powered up.
The sensor face must be submerged in liquid in order to operate correctly.

Typical installation - Set ‘Low Level’ (4mA) to be the distance from the transducer face to the bottom of the
tank. High Level should be 0.600m for most accurate and reliable measurement.

App Type
App Type is the first output and should be considered the primary measurement. If monitoring Bed level this
should be selected here. App Type has three pre-set application types.
• Bed (dense/heavy blanket layer).
• RAS (return activated sludge)
• Floc (Flocculent/hindered settling layer).
Parameter Description Options
App Typ e Set display readout Bed RAS Floc
Density Select interface to be measured See Interface Table below
Calibrat
• Manually fine tune sensor sensitivity
• Press CAL to fire a test pulse which will
return the depth measurement.
Higher value for lighter densities, lower
value for heavier densities.
Lo Level Set Lo Level measurement point (4mA) Adjustable
Hi Level Set Lo Level measurement point (20mA) Adjustable
Bed Depth(1) Set maximum expected Bed Depth - see Bed Depth(1)
for further information
Adjustable in depth (measured from
Sensor face down)
Fill Rate* Set potential filling rate for primary measurement Adjustable (units per hour)
Empty Rate* Set potential emptying rate for primary measurement Adjustable (units per hour)
*For most applications the unit is pre-calibrated with appropriate tracking speeds.
You will not need to adjust these settings.
