Sultan Sonar System
Overview

Principle of Operation
The Hawk Sultan Sonar uses state of the art Sonar technology to measure and control Waste Water
Clarifiers and Thickeners.
The system is easy to use and the innovative design provides critical plant control to optimize performance.
In the water, wastewater industry process conditions will vary greatly between a primary sedimentation tank,
secondary / final clarifier and a gravity thickener. Thickener bed levels, secondary RAS blanket, flocculent
blanket etc, all have different densities and the water above these interface levels are subject to different
process conditions that change.
To optimize performance in each interface application under all process environments:
HAWK has developed a low frequency transducer to penetrate through the suspended solids and capable of
measuring the lightest floc using one single transducer.
To optimize performance under all process environments in each interface application:
HAWK uses one transducer with a frequency and power level that is applicable to the density of the interface
and process conditions expected in the tank. Also, HAWK can guarantee performance for controlling pumps
etc, rather than for monitoring purposes only.
• Simple and easy calibration to track specic densities
• Tune Sensor to 5 preset factory densities or ne tune
to the required density in-situ
• Sonar transducer developed to optimize detection of
heavy and light density interfaces
• Easy calibration to track specic density interfaces,
eg: RAS blanket - 4g/l, oc / uff layer - 1g/l, Bed 10g/l+
• Industrial scum cleaning mechanisms that do not
require maintenance
• No wiper blade assemblies
• Wide range of communications: Modbus, HART,
Foundation Fieldbus, DeviceNet, Probus DP and
Probus PA
• 3G remote support capability for calibration,
commissioning or technical back-up from
HAWK Service Engineer
• 5 Relay alarms
• 1640 feet (500 metre) separation possible between
transducer and Sultan Sonar transmitter.
Benets
• Improved efficiency and control of the
treatment process
• Fully automated plant systems with reliable blanket
level monitoring
• Advanced warning of biological upset or hydraulic
in-balance
• Reduced maintenance with 5 year cleaning
mechanism warranty (no blades to replace)
• Reduced site operational costs significantly with
improved process control
• Improved health and safety on site
(no manual dips required).

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

Troubleshooting
Sultan Sonar System
19
Error Codes 01 - 04
Error 01
Amplifier/Transmitter can not communicate with
transducer.
• Wiring: Check the terminals for a loose or
incorrect connection (including junction box/cable
extensions)
• Check the cables for any signs of damage
• Ensure any customer supplied cable meets
HAWK specifications
• If using junction box extension trace the 8-10VDC
from the red/black amplifier terminals to
the transducer to ensure wires are correct
• If using a junction box ensure you follow HAWK
specification for extending cable
• ‘Unit Specs & Checks’ has additional checks for
causes of Error 01.
Error 02
Communication data corruption between
Transmitter and Transducer.
• It can be a result of noise in data lines or one of
data lines (white or blue) being open circuit.
• Make sure wiring is correct especially look to the
screen (earth).
• Ensure you are using quality shielded
instrument cable.
• ‘Unit Specs & Checks’ has additional checks for
causes of Error 02.
Error 03
• Specific comms mode is selected (eg Profibus, FF)
but comms module is not connected or responding
• Check your unit part number to ensure it has
correct comms
• If you do not have additional comms
(part number option X) then select Modbus.
Error 04
Amplifier is programmed with incorrect software
or has wrong hardware connected.
• Contact your local support.
Unit is measuring incorrect depth or height
• Confirm display mode is correct (Depth is measured
from sensor face to target. Height is measured from
low level to target.
• Confirm High Level and Low Level match application
requirement.
• Increase or decrease selected 'Density'. A higher
Density value programs the unit to look for a more
dense layer deeper.
• High volumes of poor settling or suspended material
with attenuate the Sonar pulse. The unit may
read higher tracking suspended material if process
conditions in the tank fail.
PLC indication does not match measurement
• Disconnect the analogue wires from the amplifier.
Use a multimeter on the 4-20mA terminals labeled
IS and + to read the direct mA from the unit. Re-
connected analogue wires and compare this value
with the reading from the control system.
• Confirm High Level and Low Level are set to the
same values in amplifier and control system.

Unit Specs & Checks
Sultan 234
Specified ranges (supply dependant): 90-260VAC,
12-30VDC, 30-48VDC). For suspected power issues
ensure user supply is appropriate & consistent.
If using AC power you can check the power supply
for faults by reading the DC +/- terminals with a
multimeter set to DC. This terminal will produce 15-
16VDC stable. If this value is lower or inconsistent
you may a problem with the internal power supply.
Unit performance will be affected if the unit detects
voltage below 9VDC. If ‘V in chk’ is on the unit will
trigger its failsafe routine. If V in chk is off the unit will
display V fail on the LCD.
Transducers
The Transducer power (red wire) should draw
8-10VDC. If this figure is too high or too low check
Sultan power & supplied power as above.
Disconnect transducer from amplifier.
There should be no open circuits between wires.
Resistances between transducer wires (approximate
values):
If any are open circuit check wiring connections or
there may be a problem with the transducer.
Transducer problems may exhibit via the amplifier
protecting itself against high current draw - measure
resistance across transducer: Red and DC:+
terminals on the amplifier while the transducer
disconnected and then connected. If the resistance
increases dramatically there is potentially a wiring or
transducer problem.
Blue - White 32Kohms
Black - Blue 15.6Kohms
Black - Red 1-2Mohm (or OV / high resistance)
Black - White 15.6Kohms
Error Codes 08 - 11 & 13
Error 08
Transducer type mismatch.
Error 09
NV ram corrupted.
Error 10
NV write error
Error 11
Transducer no. 2 communication error (cannot talk to
the sensor)
Error 13
Voltage error. Input voltage too low or voltage error.
