1CDS552 CIRRUS LOOP LOGGER
1.1 Introduction
The Cirrus Loop logger is a robust, sophisticated LTE/4G GSM logger/controller with a wide range of input capabilities,
making it ideal for a large number of measurement applications.
Communication to your own server and database can be achieved via the internet or a private APN. The software running
on these servers is supplied free of charge. The Cirrus Loop Logger has been designed to allow for easy installation and
setup without the need for a complicated server infrastructure. Setup and management software (CloudWorks) is also
supplied free of charge to allow clients to manage their own networks and data. There are no monthly charges for
collecting and hosting data as the client can provide this service themselves.
1.2 Features
Uses GPRS/EDGE/LTE/4G technology. 4G has become essential as many cellular network providers around the
world will soon no longer be supporting older GPRS/3G technologies, rendering these legacy dataloggers obsolete.
This has already started happening in many countries around the world.
Bluetooth interface - setup and manual data collection can be achieved through the Bluetooth interface negating
the need for cables that invariable fail during continuous use.
Optional external power operation with battery failover.
Uses standard off-the-shelf alkaline batteries. This logger uses 3x standard D Cell alkaline batteries that can last in
excess of 5 years under normal usage. Many other loggers use lithium batteries that are expensive and difficult to
obtain. Other problems involving lithium batteries are the restrictions when shipping using airfreight. All lithium
batteries need to be shipped as hazardous cargo that is becoming increasingly difficult to achieve as many airlines
are no longer allowing these batteries on their aircraft.
2 x Pulse input ports - Pulse inputs are used on metering devices that supply a pulse output for a measured
amount of product.
Isolated 4-20mA interface. Used for any sensing device with a 4-20mA output.

Onboard 24V 30mA power generator. The Cirrus Loop logger can generate a stable 24V output at a maximum of
30mA allowing for the powering of an external piece of equipment or current loop device eliminating the need for
a secondary power supply. This option will also function under battery operation.
Large onboard non-volatile memory - This logger can record in excess of 12350 datalog records (application
dependent).
Logging intervals from 1 minute to 1 month. Information is internally logged, time and date stamped and
transmitted at programmable intervals.
Remote programming of all setup parameters via GPRS link or SMS.
Ideal for leak detection, alarming to prevent water loss.

1.4 Architecture
1.5 Power Modes
The Cirrus Loop Logger can operate in one of two power configurations.
Mains powered - in this mode the logger can be continuously connected to the server allowing for the streaming
of live data.
Battery powered - The Cirrus Loop logger uses standard 'D' Cell alkaline batteries that will last several years
depending on the operation. In this mode, the logger will 'wakeup' (adjustable - normally 6 hourly) and upload its
recorded data to a remote database.
External 12V (8-15V) 2A supply - in this mode the logger can be continuously connected to the server allowing for
the streaming of live data. Batteries can be fitted and the logger will automatically switch to battery mode should
the power fail.

1.6.2 Pushbutton Functions
SELECT touch button - Please note, this button is touch sensitive in order to maintain the waterproof status of the housing.
Single short push will toggle the Bluetooth radio on and off.
A push of more than 3 seconds will result in the logger establishing a connection to the server and uploading its
datalog.
BLUETOOTH RESET button - This button is used to reset the Bluetooth interface in the event of a lost password or generally
configuration loss.
The Bluetooth interface of this logger can be configured to have a access password which will limit external access to only
those issued the password. Should this password get lost, the logger can be opened and the Bluetooth interface reset to
disable the security. It is advisable to then connect to the logger again and setup a new password. This is explained later in
this document.

1.7.1 External Power Supply / Solar System Connection
The CDS552 Cirrus Loop logger can be powered entirely from an external 12V (8-15V) 2A power supply or solar power
source. Using a solar power source and also populating the logger with alkaline batteries means that the logger can be put
into dual mode. In this mode, while there is solar power available, the logger will remain online with the server. Should the
solar power fail, the logger will automatically switch to 'battery' mode until the solar power source is restored. This is ideal
for remote applications where there is no mains power available and streaming data is required.
1.7.2 Using the 4-20mA loop input and 24V loop power generator
The Cirrus Loop logger is equipped with a fully isolated (optical) 4-20mA interface. This interface is configured for 2 wire
applications and should be connected as below. Please take note of the polarity of the loop connections.

To assist with the powering of loop devices, the Cirrus Loop logger is equipped with an onboard 24V loop power generator.
This generator is designed to provide the power for devices that source this directly off the loop. Since the maximum power
to flow on a 4-20mA loop, should be 20mA, the generator has been designed to supply a maximum of 30mA. Please note,
using the 24V power generator to power a loop device uses a substantial amount of power. For this reason, in battery
operated devices, the loop should only be powered each time the device needs to be read. This can be achieved by setting
the generator into 'Loop Power' mode.
Example configuration of the generator supplying power to a loop powered device
1.7.3 Using the pulse inputs
Onboard the Cirrus Loop logger are 2 pulse inputs. Pulse inputs are used by metering type devices (eg water or energy
meter) to measure consumption.
Example configuration of water meter with a volt free switch (e.g. reedswitch)

Battery Installation
1.9 Installation considerations
The CDS552 Cirrus Loop logger is environmentally rated to IP68 - max1.2m. In order to achieve this, it is critical
that any cables entering the logger are properly sealed by the IP68 gland. This gland is designed to only have
one cable exiting the logger and not multiple ones. Multiple cables will prevent the gland from achieving a proper
seal.

2LOGGER SETUP
This logger can be configured using 3 different methods:-
1. Through the local Bluetooth interface.
2. Remotely when a logger is powered and is currently online.
3. Via a scripting method for battery operated loggers that sleep most of the time.
2.1 Setup via Bluetooth Configure
The CDS552 Cirrus Loop logger has an onboard Bluetooth interface which allows for the device configuration to be done
locally. There are two different places in the software to activate the Bluetooth connection. The first option is from the log
in screen at start up.
The purpose of having it here is to allow the user to access the Bluetooth setup option without needing to connect to the
server and authenticating. This is useful in instances where there is no internet connection available in the field.

The second option is on the Zone screen by pressing the 'Device Setup' button.
Activating this function will launch the Bluetooth Server which will search for the available remote devices in the immediate
vicinity.
Once the search has been completed, a list of all the available devices will be displayed. Should the device you are looking
for, not appear in the list, press the 'Refresh' button to start the search again. Please remember the Bluetooth interface
needs to be activated before it will be found by the Bluetooth Server. This is normally done by giving the SELECT
pushbutton a short press and releasing. The blue LED will flash to indicate that the interface is active and waiting for a
connection.

To make a connection, select the device from the list and press the 'Connect' button. Alternatively, double clicking on the
device in the list will initiate a connection immediately.
Once the Bluetooth connection has been established, Cloudworks will automatically activate the correct configuration
screen needed for each device type. This device will immediately be placed into Command Mode and the current setup
data retrieved and displayed on the right hand screen.
Data update commands are sent to the device only after the parameter setup field has been left. What this means is that
while adjusting a parameter in its input box, no commands are sent to the logger. Once you have completed entering the
field and leave it for the next function, only then will the command be sent.
Datalogging functions are suspended while a logger is in Command Mode. At any point, with the logger in Command Mode,
the settings can be reread by pressing the 'Get Current Setup' button in the top menu.

To switch between the Diagnostic Mode and Command Mode, simply press the 'Command/Connect' button. Switching
from the Diagnostic Mode to Command Mode can take several seconds depending on what the logger is currently
executing. Command Mode is shown with the [COMMAND MODE] text in the communications block. All commands and
responses will be displayed in the 'Communications' block. This information can be cleared by right clicking in this box and
selecting the 'Clear Screen' option.
The logger must be in 'Command Mode' before any of the settings changes or other instructions are accepted. Sending a
command in Diagnostic Mode will cause the logger to switch to Command Mode but that last instruction will fail.
The information on this screen is ordered in various groups. The 'General Details' box holds information that is not alterable
and is general information about the logger. This information consists of the following data:

The 4-20mA current loop reading with its calibration data implemented including the unit

The 'I/O Parameter' block is the data used to setup the I/O functions of the logger. This is the place where you would be
able to synchronise the volume readings for Pulse input 1 and 2, as well as setup the configuration data for the 4-20mA
interface.
When entering the new Totaliser readings (the Pulse Readings), the pulse weights are automatically calculated and
processed in the setting of the Pulse count on the logger.
Pulse weights refer to the volume of measurement for each pulse on the input. This volume is as a ratio of the
measurement unit. For instance, if measuring cubic metres (Pulse Units=m3) and each pulse represents 100 litres, then the
pulse weight would be 0.1 - however if measuring in litres (Pulse Units=litres) and each pulse is still 100 litres, then the
pulse weight would be 100. The Pulse Reading, Pulse Weight and Pulse Units can all be entered in the 'I/O Parameter' box.
Current loop interfaces (4-20mA) work by reading the current running through a particular sensor or device. As the reading
on the sensor changes (e.g. pressure), the sensor will adjust the amount of current flowing through the interface. This
current ranges from 4mA to 20mA (max) with 4mA being the lowest reading the sensor can read (e.g. 0 bar on a pressure

sensor) and 20mA representing the highest reading (e.g. 10 bar on a 0-10 bar pressure sensor). This is a function of the
sensing device.
The interface on the logger needs to be told what the parameters are for the type of sensor attached, as well as, what that
sensor is measuring. This is done through the Loop Low Value, Loop High Value and Loop Units parameters. The Loop Low
Value would be the lowest reading for that sensor (i.e. 4mA reading), the Loop High Value, the highest reading (i.e. 20mA
reading) and the Loop Units, the unit of measure.
An example of a submersible 4-20mA level pressure sensor that reads up to 10 metres.
Loop Low Value = 0
Loop High Value = 10
Loop Units = metres
Next are the 'General Setup' parameters. These are parameters that are used for the general descriptions and applications
of the logger.
Very important here is the 'Vendor Code'. The Cloudworks System supports multiple databases. What this means is that the
server will automatically populate the database that is associated with a specific logger. Each database and logger has a
Vendor Code assigned to it. Data is matched between these systems using that code. This code is also used to separate
communications between different vendors, preventing the cross accessing of loggers by unauthorised users. The Vendor
Code is assigned to the relevant subsystem by the administrator during the creation of the database on the server.
The description is a simple string of data that is stored by the logger and used to identify that logger in simple terms. Here,
it is best to use wording that might explain something about where this logger has been applied.
Application types are explained in detail earlier in this document. To select an application type, simply click the dropdown
arrow on the right of the entry field and select the application type you wish to apply.
Since this logger has no onboard GPS, co-ordinates are recorded in the latitude and longitude fields which will be sent
through to the database during a reload device configuration event.

When using a simcard to connect to a GSM network, there are a couple of parameters that your GSM service provider will
need from you in order to connect to their network. These are sometimes not necessary as the card will automatically
connect but most will require them. The parameters are the APN Name, Username and Password.
Networks generally require you to enter the APN Name but the Username and Password are not necessary. These details
are obtained directly from your GSM service provider and most are published on their websites.
Cloudworks devices are also designed to allow for the connection to custom private APN's for purposes of security. Entering
the APN details here will result in the device connecting to your private network. These networks normally issue a static IP
address which will be shown in the 'Local IP' field in the 'General Details' box.
All Cloudworks devices connect to a server with a static IP or domain name. They usually use UDP/IP protocols and
connect, by default, on port 13000. If you are running your own server, the Server Name or IP address as well as Server Port
number need to be entered here. Just a note, it is always better to rather use the IP address than the domain name. This
will mean that the logger will not have to execute a domain name lookup before connecting to your server.
Cloudworks loggers support the use of simcard pin codes. How this works is - should a simcard have a pincode activated, it
will request the pincode when the modem powers up and starts connecting to the network. If the pincode field here is
populated, the logger will offer this code to the network, allowing it to connect. Failure of the pincode will cause the
logger to abort the connection attempt and shutdown.
With regards to Domain Name Servers (DNS), most service providers will use their own predetermined DNS servers so
these entries are normally left blank. However, should you require your own DNS servers, you can capture their Names/IP
addresses in the Primary and Secondary DNS fields.
Similarly, SMS Service Centre number is normally not required as your network will default this value. This can be
customised using the 'SMS Serv. Centre' field.
If you are using a foreign simcard on a network, the logger will need to be told that it is allowed to use data roaming.
Without that, the logger will shutdown communications if it detects a roaming data connection. This can be done by ticking
the option box.
The Wakeup Period refers to the time a logger remains asleep before waking and connecting to the server to upload its
data. The Datalog Period is the time between each recorded datalog entry.
