1.2 SAFETY CONSIDERATIONS
Safety Note:
Before continuing, carefully read and follow the information in the “Safety Warnings
and Approvals Information” document supplied with the product.
This provides general safety information.
The installer or maintainer must also refer to any other safety supplement documents,
supplied with the intrinsically safe versions of the product. This will provide additional
ATEX-related safety information including port parameters. (“ATEX” refers to use of the
product within a potentially explosive atmosphere).
Retain all documents for future reference.
Before using this product, make a risk assessment of the installation site and expected
work activity. Installations in a hazardous environment (e.g. ATEX) should be carried out
by appropriate technicians with suitable training for that environment. Ensure any tools
necessary for installation are suitable for use within the hazardous environment. Ensure
suitable protective clothing is worn and working practises are followed during
installation and any maintenance. Check with the site owner or supervisor for any
additional safety requirements before commencing work.
Within an ATEX environment, only use an Intrinsically Safe model of the logger. Confirm
from the model number of the unit and also that the device label has suitable ATEX
markings.
Ensure any communications device being used to assist in the install or setup of the
logger is also suitable for use in any hazardous environment in which you are working.
The logger can also be used in non-ATEX applications.
1.3 OPERATING TEMPERATURE
Refer to the logger Datasheet or your sales representative for guidance on the storage
and operating temperature range of the device. Ensure the unit is within the operating
temperature range prior to installation.

2OVERVIEW AND PREPARATION FOR USE
2.1 LOGGER -DEVICE OVERVIEW
The ISLog and Comlog2 IS products are similar families of logger devices.
•Comlog2-IS - Automated Meter Reading applications.
•ISLog - Other applications.
2.2 PREPARING A MOBILE PHONE (OR SIMILAR DEVICE)FOR USE WITH LOGGERS
The logger devices require a user-interface in order to setup and test the unit. This is
provided by means of an app which is to be installed onto a mobile phone (or similar
device). The mobile phone must have Bluetooth-Low-Energy (BLE) compatibility, GPS
and Internet capability.
The HWM IDT app is the required app.
Refer to the IDT app User Guide for details of its installation and general use.
Follow the directions including installing any additional apps that are required.
The installer is required to be familiar with the use of IDT and any other required apps.
2.3 LOGGER OPERATION
The logger is powered by a non-rechargeable Lithium battery. The software is designed
to minimise battery use and thereby prolong the expected battery life. However, battery
life is also affected by user-programable settings. The user is advised to set the logger to
keep tasks and sample frequencies to the minimum requirements of the intended use
in order to manage battery power effectively.
Refer to the IDT app user-guide for an introduction to basic, general-purpose, logger
operation.
The logger is normally shipped from the factory in an inactive state to preserve the life
of the battery. When activated (see section 3.1) , the logger will go into the state of
“Recording” and begin repetitive logging of the various sensors fitted to the unit,
according to its configuration and settings.
The loggers make repetitive measurements which are saved as datapoints into an area
of memory which is referred to as the “primary recording”.
If the logger has the feature enabled, loggers can also be set to occasionally save
additional data into a “secondary recording” memory area, (e.g., data sampled at a
higher frequency).
Note: This is not available on all supplied units and must be arranged through your
sales representative before placing an order; it has implications concerning
expected battery life of the unit).

6
2.4 SERVER INTEGRATION –STORING AND VIEWING DATA
The logger includes an interface (referred to as a modem) that provides access to the
internet via the cellular mobile communications network. A SIM card is used to give
access of the network.
Measurement data is initially stored within the loggers, until the next call-in time. The
data can then be uploaded to the server using an encrypted format. Typically, the server
used to receive and store the data will be a HWM DataGate server, although other
servers may be used in conjunction with HWM software.
The logger data may be viewed using a viewing portal which has access to the data
stored on the server. (Refer to the relevant user guide for details of how it can be used
to view the logger data).
2.4.1 DataGate Server / Data viewing portals
When integrated with HWM’s DataGate server, the logger’s measurement data can be
stored centrally and made available to users via a viewing portal (website).
The data can be viewed remotely / graphically by anyone with a suitable user account
(and password) using a standard web-browser.
DataGate can also forward any alarms received from the unit to all users that have
subscribed to them.
Use of the loggers with the DataGate system can offer security features for certain
loggers (see section 2.5).
DataGate can also (by arrangement with your sales representative) be used to export
logger data to other servers.
Some administrative setup of the server and the viewing portal is normally required to
facilitate storing and presenting logger data correctly. Setup of and use of the DataGate
system are not covered by this user guide.
Note: Some loggers have a specific requirement to be used with DataGate in order to
meet their security features (if enabled). (see section 2.5).
(For illustration purposes only)

7
Depending on the type of sensor used with the logger your data may be alternatively
viewed via a dedicated website which is designed to better present data from the
sensor. Refer to the sensor user-guide or IDT app user guide to see if this is appropriate
or discuss with your HWM representative regarding which viewing portal to use.
2.5 LOGGER SECURITY:SECURE AND UNPROTECTED MODES
The logger has certain security feature options. Refer to the IDT app user-guide for an
explanation of each option.

8
3ACTIVATING THE LOGGER AND COMMUNICATIONS LINK
3.1 LOGGER ACTIVATION PROCESS (FOR FIRST-TIME USE)
When shipped from the factory, the unit is deactivated. This mode is designed to
preserve its battery life whilst being shipped or in long term storage; this is often called
“shipping mode”. To use the logger, it must first be activated. The process for doing this
is the same as required to activate its Bluetooth-compatible communications link.
(Refer to section 3.2).
3.2 COMMUNICATIONS LINK FOR USE WITH IDT
The logger includes a Bluetooth-compatible radio interface, used for short-range
communication to a suitable mobile phone. This enables the user to communicate with
the logger using the IDT app during installation and on-site test. (No communications
cable is required).
The radio interface is short-range, and infrequently needed (it is only required when
someone is attending to the logger on-site). The communications circuit is therefore
normally on standby.
To temporarily activate the communications, a magnet is required.
On the side of the logger there is a label showing a
magnet symbol. A magnetic field sensor is located
under this label.
A strong magnet must be constantly held in front of
the label for 12 seconds to activate the
communications link.
Communication remains open for around
120 seconds, but this period is extended if communications is in use; the
communication link remains open for 600s after it was last used. The link then goes
back into standby.
Note: This action is sometimes referred to as “swiping the logger”.
3.3 ACCESS CONSIDERATIONS
Whenever choosing a location to mount the logger,
ensure there is sufficient space at the side of the unit to
access the magnetic sensor.
This will allow the communications link to be
activated without the need to remove the logger.

9
4INTERFACES AND SENSORS SUPPORTED
The ISLog and Comlog2 IS families of logger devices share a common plastic case.
Use the key-hole shaped mounting holes to mount the logger. Holes are also provided
for applications requiring anti-tamper seals to be applied.
The loggers are of a waterproof construction and waterproof connectors exist for use
with certain sensors and the antenna.
The logger is labelled with numbers at each possible location of an electrical interface; The number is
etched into the plastic. This is a location identifier, for manufacturing use.
Before connecting the logger to any other equipment, check the correct unit is supplied.
When working within an ATEX environment, verify the port-parameters are suitable for
interconnection.
Supported sensors and interfaces is model-dependent. The interface type at each
location can be determined by inspecting part of the model number.
HIS / xxxxx / xx / xxxxxx /x. Refer to the drawing (above) and the key below:

4.1 TAMPER ALARM SUPPORT FOR FLOW SENSOR (METER PULSE DETECTOR)
Tamper alarm is an available setting option for a digital Flow sensor.
IDT provides programming support independent of any cable that is used for the
tamper detection circuit. However, not all cable options give adequate protection for
tamper-detection. A fundamental requirement is that the meter pulse detection and
tamper detection circuits share the same cable; detaching the connector from the
meter can then be programmed to cause an alarm.
Compatible Suitable Connector options
Feature Interface types required to support.
Digital Flow sensor 1, 8, 9 R (RJ11 plug),
(Single cable with Tamper Alarm option) B (Binder connector),
F (Fischer connector).
•Tamper alarm for the digital Flow sensor must be enabled in IDT.
(Refer to IDT user guide).
•The meter must internally interconnect (loop) the two signals used for tamper.
4.2 PULSE REPLICATION SUPPORT FOR FLOW SENSOR (METER PULSE DETECTOR)
Pulse Replication is an available option for use in conjunction with a digital Flow sensor.
Pulse replication is used to daisy-chain (connect) equipment together that use the
meter-pulses from the meter.
Requirements are that:
•A digital Flow sensor and channel should exist on the logger which is connected
to the meter-pulse output of the meter and
•Pulse replication must be output onto a second connector, which must be fitted;
meter-pulses are never fed back into the originating equipment.
•Pulse replication setup option must be enabled in IDT.
(Refer to IDT user guide).
4.3 LOGGER CHANNEL TYPES AND DATA INTERPRETATION
Refer to the IDT app user guide for an introduction to this topic.
The loggers comply with the description and examples of setup provided therein.
Where required, IDT can be used to check or make any changes to the logger settings.
Note: The logger will usually have settings pre-programmed by the factory prior to
shipping. However, the installer has responsibility for confirming the settings
are appropriate for use at the installed site.
If you have specific requirements this can be discussed with your HWM sales
representative at the time of ordering the loggers.
The Configure Device pages will have considerable variation in content depending on
the logger model number and the sensors being installed.
Follow the general guidance within the IDT-app user-guide for most sensors. However,
some HWM sensors require specialised setup screens or have their own user-guide
which provides further guidance.

5INSTALLATION
Consider any particular safety requirements of the installation (e.g., ATEX).
5.1 SUMMARY
•Check the logger is suitable for use and that you have the required sensor
attachments. Check port-parameters are compatible for a logger being used in
an ATEX environment.
•Activate the logger communications and select the logger device using IDT.
•Use IDT to:
oProgram a local time-zone into the logger.
oCheck / modify the communications settings of device, as required:
Call-in settings,
Data Destination settings,
SIM settings (network access),
Modem settings (Network technology).
oCheck / modify the timing parameters for making measurement samples.
oCheck / modify channel settings for producing datapoints.
Where required, undertake any additional operations required for setup
of the channel (e.g. add an initial meter reading, pulse replication setting,
sensor calibration; these will be dependent on sensor and use).
oSet any Trigger-Actions required for each channel.
oTest the logger sensors are functioning correctly.
(Some can be done pre-installation; others post installation).
•Install the logger and sensors.
Refer to the orientation shown in the diagram in section 4. The logger should be
installed as shown for optimum battery performance.
Determine the location and cable / hose routing prior to commencing work.
Install anti-tamper seals to the device after installation (if required).
•Install the antenna.
Choose suitable location options for the antenna and test in each location until
the optimal position is found.
Test using signal test and call test with any access door / chamber lid open
initially and then closed.
•(If required) transfer details of the logger to the Deployment app.
(The HWM Deployment app is then used to complete the task of selecting the
site of deployment and update of the DataGate system).

12
5.2 INSTALLING THE LOGGER
The logger must be mounted in a suitable location where the sensors attached to it can
reach their intended installation points. The cables should be routed without causing
any hazards. Position loggers, sensors, and antenna away from sources of electrical
interference such and motors or pumps.
Refer to section 3.3 regarding access considerations for activating on-site
communications.
Use the keyhole mounting holes to fix the logger in position. Anti-tamper seals can be
used if required to bear witness if anyone has interfered with the installation by
disassembling the logger. (See diagram in section 4)
Ensure the antenna can be mounted in a suitable location where the radio signal will be
of sufficient strength to call into the cellular network.
Note: Certain sensors have their own instructions regarding installation requirements
and their configuration using IDT.
Follow the additional guidance where available.
5.3 INSTALLING THE ANTENNA AND TESTING CELLULAR COMMUNICATIONS
Only use HWM-provided antenna for use with your logger, to ensure the radio interface
meets approvals requirements (safety, etc).
The logger family has several antenna connector options:
•Internal Antenna (no antenna connector fitted).
•Antenna (plastic connector shell).
•Antenna (metal “FME” connector).
An antenna with the appropriate connector should be selected and attached, tightening
finger-tight only. No sharp bends should exist in the cable routing of the antenna.
If possible, avoid locations where the antenna could be adversely affected (e.g., by an
occasional flood condition).
The IDT app should be used to check that the logger can connect to the cellular network
and that the antenna is in the optimal position for the site.
•Choose a suitable antenna for the installation and decide on its initial position.
•Perform the “Signal Test” to confirm the logger connects to the mobile network
and find the best location of the antenna.
•Perform a “Call Test” to confirm the logger can communicate with the DataGate
server.
(Details of use of IDT for making these tests are provided in the IDT app user-guide).
Trouble-shoot a call-test failure if required, following the advice in the IDT app user-
guide (MAN-2000-0001). Further information is given in the HWM Antenna Installation
Guide (MAN-072-0001), and on the webpage shown below.

FME

13
Monopole Antenna
For most installations, a monopole antenna will give acceptable performance.
Installation Considerations:
•The antenna has a magnetic base to be used for mounting.
•For optimum performance, the antenna requires a “ground plane” (metal
surface). Consider installing a metal bracket made of a ferrous material to
attach the magnetic base of the antenna if space allows or signal strength
is marginal.
•When installing the antenna in large underground chambers it should be
positioned close to the surface.
•Ensure that any chamber lid will not interfere with the antenna or cables
when being opened/closed.
•This antenna is vertically polarised, it should always be installed in the
vertical orientation.
•Never bend the radiating element of the antenna.
•The antenna can also be attached to an installation bracket mounted to an
existing marker post.
•Where an antenna is held in place by magnets, ensure the weight of any cables
does not excessively load the magnet so as to detach it from the installed
location.
•Do not allow any equipment to rest on the antenna connector as crush damage
to the connector or antenna cable can result.
For other antenna options and guidelines, refer to the documents available on the
HWM support webpage: https://www.hwmglobal.com/antennas-support/
6VIEWING YOUR DATA
The data of the connected logger can also be viewed graphically by using the IDT app to
make a temporary copy of the data stored within the logger.
Refer to the IDT app user-guide for instructions on how to do this.
The logger usually calls into a server, where the data can be stored for the entire
deployment period to a site (see also section 2.4). Site data is best viewed with the
viewing tool linked to this data-store. For certain applications, the viewing tool can
display the status of multiple deployed devices simultaneously (e.g. a representation of
the status of each site a map). Refer to the appropriate manual or instructions for your
viewing tool for guidance.
IDT is not designed to support such fleet-wide views of data.

14
7TROUBLESHOOTING
The IDT app, the logger, the user and sometimes the server interact with each other.
Any issues should consider all four parts of the system.
Refer to the IDT app user-guide for advice on various problems which can occur with
use of the logger.
