Instructions specific to safe use
Intrinsic safety
Intrinsic Safety is an electronic hardware protection concept that ensures there
are no conditions under which the equipment can operate that could cause a
release of energy sufficient to ignite a flammable gas. Devices that meet these
design criteria are deemed Intrinsically Safe (IS).
Special design, testing, quality and inspection rules apply to manufacturers and
users of IS equipment due to the critical nature of their deployment in hazardous
areas. Areas where hazardous atmospheres exist are classified as Class,
Division or Zone depending on the country. Users should check local and
governmental safety policies as a minimum before installing this equipment in a
hazardous area or confined space.
The Hydro-Logic® Flexi Logger 300Ex is certified to the European ATEX
(Atmospheres Explosives) standard and to the International IEC Ex standard.
Many countries accept the ATEX and IEC Ex standards in lieu of their own
country specific requirements. It is the customer’s responsibility to ensure
that certification on the Flexi Logger 300Ex and sensors meets the
applicable regulatory requirements.
System certification
The Hydro-Logic®Flexi Logger 300Ex is certified for use only with approved
sensors, batteries, communication cables. Connection of any non-approved
components could result in unsafe operation and will immediately void the
warranty and Hazardous Area certification.
Hazardous Area installations
The Hydro-Logic®Flexi Logger 300Ex is certified for installation within Zone 0
Hazardous Areas by the application of the ‘ATEX’ Directive 2014/34/EU, Annex II
1.0.6. and IEC EX scheme.
The following instructions apply to equipment covered by the certificate and
variations:
1. Equipment may be used with flammable gases and vapours with apparatus
Groups IIA and IIB and with temperature classes T1 to T4.
2. Equipment is only certified for use in ambient temperatures in the range -20oC
to +40oC and should not be used outside this range.
3. Installation shall be carried out in accordance with the applicable code of

5. If the equipment is likely to encounter aggressive substances, then it is the
responsibility of the user to take suitable precautions that prevent it from
being adversely affected, thus ensuring that the type of protection is not
compromised.
Aggressive substances –are acidic liquids or gases that may attack metals, or
solvents that may affect polymeric materials
Suitable precautions - e.g. regular checks as part of routine inspections or
establishing from the material’s data sheet that it is resistant to specific chemicals
There are no special checking or maintenance conditions other than a periodic
check of the equipment
Special conditions of safe use apply, see below.
Conditions of safe use
Data transfer via the Local COMM connector is permitted only in a non-
hazardous atmosphere. The supply for the equipment connected to this port must
be approved as SELV or Class 2 equipment against UL 60950-1, UL 6101-1 or
an equivalent IEC standard. The maximum voltage from a data transfer device
shall not exceed 19.7Vdc.
The Hydro-Logic®Flexi Logger 300Ex is normally used in damp environments
and is unlikely to be placed in a position where an electrostatic build up can take
place. Under certain extreme circumstances, the non-metallic parts incorporated
in the enclosure of this equipment may generate an ignition-capable level of
electrostatic charge. Therefore, the equipment shall not be installed in a location
where the external conditions are conducive to the build-up of electrostatic
charge on such surfaces. In addition, the equipment shall only be cleaned with a
damp cloth.
The SIM card shall only be changed when an explosive atmosphere is shown to
be absent; the cover should be replaced before use

Getting started
These instructions assume
•You are unfamiliar with the Hydro-Logic®Flexi Logger 300Ex
•You have purchased the logger with a Timeview data collection and
configuration package, including SIM
•You have ordered the logger with a sensor
•You have ordered the Pre-wiring and configuration service
The instructions cover the most important aspects of logger operation. They
should be carried out before the logger is installed on site.
Powering the logger
The logger is shipped in the OFF state. To power it, you must open the
enclosure and plug in the HLC module.
Once you do this, you should see a green flash on the LED
The logger is now ON. You should see a blue LED flash every two seconds.
There are other patterns of LED activity, which are described in Status LED flash
patterns.
You can power-down the logger by removing the HLC module.

Hydro-Logic®Flexi Logger 300Ex
User Manual
22 August 2018 Page 15 of 74
Note that the internal clock is stopped when the logger is switched off, but the
configuration and stored data are preserved. You need to reset the logger clock
after it is switched on so that data from the sensor is correctly time-stamped.
This can be done either by Resetting logger clock with Timeview or Resetting the
logger clock with Harvest
Connecting to Timeview
With the logger on, press and hold the dial-out button (1) until you see a yellow
flash on the LED. The dial-out can also be triggered with a strong magnet near
the reed switch (2), without the case being opened.
The enclosure should never be opened in the Hazardous Area.
The logger will then begin a series of steps to call out to Timeview. Progress can
be followed using the Status LED flash patterns, or you can just wait for a few
minutes until the red, blue and green flashing has stopped and the logger has
gone back to a single blue flash every 2s.
Now see Finding your data on Timeview –you should be able to see that your
logger has connected successfully.
If the mobile data signal is poor, the logger will try several times to transfer data
to Timeview, so there is no need to press the dial-out button more than once.

22 August 2018 Page 16 of 74
Recording test data from the sensor
If you have ordered the Pre-wiring and configuration service, the sensor can
immediately be connected to the connectors labelled S1 to S3 on the logger
body.
If you need to wire your own sensor, see the section Sensors for more
information.
Once the sensor is connected, you should ensure that the clock is reset (either by
Resetting logger clock with Timeview or Resetting the logger clock with Harvest)
This will clean any blank data points that were recorded with no sensor
connected, and ensure that data points from the sensor are correctly time-
stamped.
Now leave the logger to record some data. The logger will be configured to take
measurements every 5 or 15 minutes, so leave it for half an hour or so.
Finally, either press the dial-out button to send data to Timeview or read the
logger with Harvest. You should now see data points from your sensor(s) in the
Harvest plot or the Timeview Logger Profile.

Hardware configuration and installation
Device overview
Refer to the block diagram below. The Hydro-Logic®Flexi Logger 300Ex is
controlled by a low-power microcontroller. There is a sensor interface with HART
modem, 3 sensor connectors and storage on local memory for the logger
configuration and typically several months of time-series data.
A 3G mobile data modem is used to transfer data to a remote data collection
system via either an internal and or external antenna. The modem includes a
standard SIM interface.
The orange lines show the power distribution. There is an internal battery which
can typically provide years of operation. The HLC is a small module containing a
rechargeable battery which provides boost power for the modem and sensor as
required.
