Benefits of using mating Smart Digital
DSS RS-485 Modbus RTU Sensors
• Integral RS-485 MODBUS RTU interfaces all-modern PLC controllers & data acquision systems.
• Communicator provides easy management of eld installaons without the cost of a mang transmier.
This is ideal for locaons where a local display is not necessary or possible due to installaon limitaons.
• Intelligent management of sensor calibraons and service life-cycle for ecient commissioning & maintenance.
All aspects of the installaon are completely portable from the shop to the eld site locaon.
• Days in use-value is stamped for calibraons that are performed. This allows for predicve scheduling of
maintenance in the PLC to ensure accurate measurement in the eld based upon user-dened criteria.
• All digital sensors ensure reliable operaon even in noisy process environments, unlike analogue sensors.
• No degradaon in digital communicaons even with very long cable runs. Max 1,000 meters (3,280 feet) for
pH, ORP, ISE & DO sensors and Max 300 meters (1,000 feet) for conducvity sensors with TT-MA-DSS.
• Bridging connecons & modifying installaons easily without loss of signal quality with NEMA 6P & IP67 rated
quick connect waterproof and corrosion-resistant dual quick connect plugs. Simple plug and play operaon for
intelligent maintenance planning & smart management of sensor installaons and stocking.
• Quick connect digital extension cables facilitate consolidaon of very many DSS sensors outputs into a one-pan-
el enclosure where very many remote eld installaons can all be conveniently viewed at once.
• Intelligent DSS handheld eld communicator soware idenes the type of sensor connected & autoloads
correct features. There exists no possibility of accidentally using the wrong set of opons or sengs.
• All Extension cables for DSS sensors are inter-compable. Uniform extension cables minimize stocking.

Warranty
Product Warranty
Every Turtle Tough product is thoroughly inspected and tested before leaving the factory and prior to shipping. In
addion to any statutory rights and remedies you may have, Turtle Tough warrants all its products against defecve
workmanship and faulty materials for 12 months from the date of purchase and undertakes, at its opon, to repair
or replace, free of charge, each product or part thereof on condion that:
• The complete product is returned to Turtle Tough or one of its authorised service agents, in person or freight
pre-paid by you, and found, on examinaon, to be suering from a manufacturing defect.
• The product or relevant part has not been subject to misuse, neglect, or been involved in an accident.
• The repairs are not required as a result of normal wear and tear.
• Damage caused by wear and tear, inadequate maintenance, improper installaon, corrosion, or by the eects
of chemical processes is excluded from this warranty coverage.
Sensor Warranty
Turtle Tough sensors are electrochemical devices and as such have a limited operang life. Life expectancy
depends on the eld of applicaon such as the medium, pressure and temperature. It can vary between a number
of weeks to several years. There are special cases in extreme environments where operang life will only be a few
days. Characterisc and response me will also change with aging. As such electrochemical sensors are arcles
of consumpon and are not subject to a common guarantee. Replacements or exchanges are generally excluded
unless a manufacturing defect is determined to be the cause. It is not possible to predict the rate of deterioraon
for a parcular process, nor can we provide a guarantee on sensor life because it is impossible to predict the
rate of exposure, contaminaon and deterioraon. Damage caused by wear and tear, inadequate maintenance,
faulty installaons, corrosion, or the eects of chemical processes is excluded from this warranty coverage. Our
agents or representaves may provide you with a life expectancy guide based on similar applicaons we have
experienced, however, this in no way constutes a warranty of performance and is a general indicator.
Shelf Life Warranty
The standard shelf life for a Turtle Tough sensor is one year from the date of shipment. Sensors stored longer
than this period may sll be funconal but are no longer under warranty. Sensors should be stored in a cool, dry
locaon with the sensor p (where the pH/ORP element is located) oriented toward the ground. All pH/ ORP/ISE
sensors come standard with a condioning soluon in the cap. This condioning soluon is 50% pH 4 buer and
50% saturated potassium chloride (mixed by volume). The sensor cap should be kept ghtly axed to the sensor
body and sealed with common piping Teon tape when the sensor is not in use. Sensors that are to be returned
for a shelf-life warranty claim must have the original sensor cap and condioning soluon intact to be eligible for
warranty replacement.
Damage to Internal Electronics
Damage to the sensor’s internal electronic components is not covered under warranty. Analogue sensors with
internal preampliers are sensive to electrostac discharge. Sensors with preamps are clearly marked and extra
care must be taken when handling these sensors as human contact with the electrical connecons can discharge
stac to the preamplier causing it to blow. This will render the product inoperable. Addionally, sensors
containing digital RS485 boards are suscepble to damage when powered incorrectly or improperly installed. Sensors
containing internal electronic boards undergo addional quality checks prior to shipment to ensure that
components are 100% operaonal upon delivery. Ground loop and 3rd party hardware problems (including but
not limited to power supplies) may also cause blown electronics or damage to the sensor components and as such
faulty installaons are not covered by warranty.

Damage to Cables and Connectors
Please note that integral sensor cables, connectors and plugs must NOT be cut, removed or modied in any way.
Sensors contain sensive internal electronics and our cables and connectors are designed to protect the integrity
of these components. Any modicaon or alteraon to cables and connectors can compromise their integrity
and will void the warranty. Always use factory-approved/manufactured cables and connectors. Addionally, the
cable contains a unique idener laminated to the cable end and this must not be removed or it will also void the
warranty.

TURTLE TOUGH DIRECT SMART SENSORS (DSS) are fully supported by a range of factory hardware soluons
including SMART Analysers, Handheld Field Communicators, PC Communicaon tools and eld implementaon
devices such as juncon boxes, extensions leads and power supplies. This ecosystem provides a complete soluon
for reliable connecvity and sensor management.
TURTLE TOUGH sensors may also be directly interfaced with end-user hardware via the MODBUS RTU protocol.
Integrang sensors directly into your industrial network requires a moderate to a high level of onsite experse
in system integraon and should ONLY be undertaken by someone with the requisite experience. While direct
integraon provides some signicant benets, it also incurs a higher degree of risk as integrang with 3rd party
hardware provides a lot of opportunies for unexpected issues to arise. 3rd party hardware includes any device or
component not supplied by Turtle Tough and can include, but is not limited to, PLC’s, SCADA systems, DCS’s, data
loggers, power supplies/isolators, or any other externally sourced interfacing device or component. We suggest
you read the sensor implementaon guide carefully to understand the full scope and requirement for installaon,
because:
1. Turtle Tough Pty Ltd and its representaves can provide only limited factory support when integrang sensors
with 3rd party hardware. Unexpected behaviour or damage as the result of 3rd party hardware is not the
responsibility of Turtle Tough.
2. Product support is limited to the informaon provided in our eld implementaon notes and guidelines. The
product is fully supported for installaon requirements, eld implementaon and programming protocols in
direct relaon to our product. It does not extend to the compability of our sensor with or the subsequent
behaviour of 3rd party hardware. Due to the innite amount of 3rd party hardware available we are unable to
support issues related to 3rd party problems and it is the sole responsibility of the end-user to test and verify
the compability of our product with their equipment.
3. Turtle Tough and its representaves are unable to provide support on 3rd party hardware or provide trouble-
shoong on equipment not supplied by us. If you intend to integrate the sensor directly with your hardware,
we highly recommend the following:
• Read the Field Installaon Guide and Sensor Implementaon Guide. Make sure you understand the requirements
and please contact us if you require claricaon or further informaon.
• Seek advice from your 3rd party hardware provider and make sure this equipment meets the minimum
specicaon requirement outlined in our support documentaon.
• Purchase a handheld eld communicator (HFC) from Turtle Tough. This stand-alone device, self-powers the
sensor and provides complete diagnoscs and communicaon. The HFC allows us to independently test and
verify the sensor performance, independent of your system or hardware and is the single fastest way to rule
out any sensor performance issues and be able to idenfy eld installaon problems.
• Alternavely, you may purchase a windows PC interface box. Once again, this factory-supplied and tested
component will ensure reliable communicaon with the sensor and it can be tested independently of your
system.
• Please note that our quick connect plugs must never be removed or modied in any way. This will immediately
void the warranty. Only use Turtle Tough factory interface leads or panel mount connectors to interface with
your hardware.
