DESCRIPTION

1. PRODUCT DESCRIPTION
1.1 General
The GS01 is a wireless, battery powered point detector that monitors the
concentration of hydrocarbon gases.
It uses a combination of two sensors:
1. An ultrasonic speed-of-sound sensor that continuously monitors changes in
the ambient air composition.
2. An optical (infrared) absorption sensor that is used for accurate
measurements of the hydrocarbon gas concentration.
The infrared sensor uses more power than the ultrasonic and is therefore kept in
watch mode if the ultrasonic sensor does not detect any changes in the air
composition. The infrared sensor applies optical MEMS (micro electromechanical
system) technology to enable intermittent operation with fast start-up and
measurement, and thus very low average battery consumption.
The measured gas concentration is transmitted wireless using the ISA100
Wireless™ standard. This manual does not cover the wireless router or gateway
and the connected control system (please refer to the list of references in Section
9 providing examples of relevant documentation).
The detector is intrinsically safe, with equipment protection level Gb (Ex ib) (see
Section 7) intended for use in zone 1 and 2 areas.
Two models are available of this gas detector:
- GS01 with fixed antenna
- GS01-EA with extended antenna
All information in this manual for the GS01 also applies for the GS01-EA unless
explicitly otherwise noted.
1.2 Measuring principle
The GS01 detector utilises infrared absorption spectroscopy. The fundament is
the Beer-Lambert Law, which relates the absorption of light to the properties of the
material through which the light is travelling.
The internal radiation source emits infrared radiation through a lens and a
sapphire window into the measuring cell (cf. Figure 1-1 and Figure 1-4). A mirror
at the opposite end of this cell returns the beam back through the sapphire
window into the internal volume of the detector and onto a filter that disperses,
focuses, and modulates the incident light. This filter is a patented silicon MEMS
component proprietary to GasSecure.
By applying a control voltage to the MEMS chip it is switched between the so-
called gas state and the reference state. In the gas state a wavelength where
hydrocarbons do absorb light is focused onto the detector, whereas two

GasSecure GS01
Hardware Manual
6 CHAPTER 1
wavelengths where hydrocarbons do not absorb are focused onto the detector in
the reference state. The GS01 detector uses the same light source, light path and
photodetector for both measurements.
This single beam, triple wavelength detection is unique to the GS01 from
GasSecure.
1.3 Instrument description
The GS01 consists of the main housing (316L stainless steel) with mounting
bracket, the measuring cell, an antenna (note that the GS01-EA features an
antenna connector instead), and the battery compartment (cf. Figure 1-1).
Attached to the main housing are the following detachable parts:
•Weather cap (Polyamide 6)
•Battery cap (Polyamide 6)
•Battery package (Polyamide 6)
Except for these detachable parts, the user shall not disassemble the sensor any
further. When the weather cap is removed, the infrared measuring cell with the
sapphire window on the main housing and the mirror at the outer end, is open and
accessible for cleaning. The ultrasonic sensor is protected by a perforated steel
sheet, which shall not be removed.
1.4 Battery
The GS01 may only be used with the GasSecure battery pack (Part number
10055). The battery pack is designed for two Lithium-Thionyl Chloride size D cells
in series, and has a nominal output voltage of 7.2V. The battery pack has an
internal charge counter. The battery pack is intrinsically safe (see Section 7).
1.5 Outline dimensions
Figure 1-1 shows the sensor buildup with an exploded drawing. Figure 1-2 and
Figure 1-3 depict the GS01 and GS01-EA dimensions, respectively.

2. INSTALLATION
Note: The GS01 gas detector certification must comply with the legal requirements
following the area classification at the installation point.
The detector shall be installed where it is most likely to detect gas in the event of a
leakage.
For battery pack installation see Section 5.4.
In areas with significant exposure to direct sunlight and the risk of temperatures
beyond the operating temperature range, a sunshade should be considered (see
list of spare parts in Table 5-1).
2.1 Tools
The following tools are needed to install the instrument:
•Open-end spanner for M8 bolts (alternatively 5/16” bolts)
•Face spanner with two pins in size 75x6 (distance x pin diameter) as
optional tool to remove the battery cap
•Torx screwdriver T10 for battery cell replacement (cf. Section 5.4.2)
2.2 Mounting
The detector is mounted with its long axis horizontally. For the standard GS01
make sure, to the extent possible, that the antenna is vertical (pointing up or
down) and that local radio shadowing is kept at a minimum. The GS01-EA may be
mounted in any horizontal orientation.
Two M8 bolts (alternatively 5/16” bolts) with washers under the head are used to
attach the bracket. The bolts should be spaced from 85 to 95 mm to easily fit the
slots when mounting the detector.
The weather cap must be mounted with the arrow on the cap pointing upwards,
regardless if the antenna is pointing up or down (cf. Figure 2-1). If possible, mount
the GS01 with the weather cap oriented away from the prevailing wind direction.
Do not use the GS01 detector in ventilation ducts or pipes.
Do not mount the detector directly above hot or cold surfaces. If the detector is
mounted inside metallic structures or enclosures the GS01 detector with extended
antenna (GS01-EA) should be considered.

GasSecure GS01

10 CHAPTER 2
2.3 Grounding
The detector housing must be connected to ground for operation in hazardous
areas. This to avoid possible static charge build-up, which may arise from
electrically isolated metal parts. Ground the detector either by mounting it on a
grounded metallic structure or by connecting a grounded wire to the screw holes in
the mounting bracket (cf. Figure 2-1).The resistance to ground must be less than
1 GOhm.
2.4 Sun shade / weather protection
The sunshade is available as optional accessory and recommended for locations
with high ambient temperature and / or direct sunlight exposure. It may also be
used as weather protection for instance in locations with frequent heavy
precipitation. The shade is fixed to the gas detector bracket with the same M8 (or
5/16”) bolts, which are used for detector mounting. Make sure that the sunshade
is mounted the correct way so that the detector identification plate remains visible.
Figure 2-1: Correct position of the weather cap and location of earth point.
The arrow must always point up regardless of the detector orientation.
2.5 External antenna (applies only for GS01-EA)
The external antenna is connected to the detector with the antenna cable as
shown in Figure 2-2. The properties of the antenna cable supplied by GasSecure
are shown in Table 2-1. The GS01-EA detector is certified with the coaxial cable
and the omni-directional antenna in Table 5-1. Note that the approved cable
length range is 0-30 m. Do not connect any other antennas than those listed in
Table 5-1.
The external antenna is delivered with a bracket (refer to Reference [10] for
bracket dimensions) and metal bands for easy fitting to a pole (25 – 101 mm) or

3. COMMISSIONING
The GS01 detector(s) is (are) set up in a wireless sensor network with a gateway
and router. The exact commissioning procedure depends on the selected type of
gateway. Therefore, this manual must be used together with the relevant
documentation written for the respective gateway. Some references for such
documentation are provided in Section 9.
On completion of commissioning, the proof test, as described in Section 4.2,
should be executed to validate the correct mapping of the detector output data.
3.1 Communication
The GS01 detector complies with the ISA100 Wireless™ standard for wireless
communication.
Each GS01 detector must be paired with a single gateway, before it can
communicate with the network. The gateway is the interface between the wireless
and plant networks. It marks the transition between communications compliant to
the standard and other communications, and acts as a translator between ISA100
Wireless™ and other protocols (Modbus, PROFINET, etc.).
The pairing process, where the device obtains the appropriate security credentials
and network-specific information, is referred to as provisioning and is explained in
Section 3.7.
3.2 ISA100 Wireless™ standard
ISA100 Wireless™ is a wireless networking technology standard developed by the
International Society of Automation (ISA).
This ISA standard is intended to provide reliable and secure wireless operation for
safety, control, and monitoring applications. This standard defines the protocol
suite, system management, gateway, and security specifications for low-data-rate
wireless connectivity with fixed, portable, and moving field devices supporting very
limited power consumption requirements. The application focus is to address the
performance needs for periodic monitoring and process control where latencies on
the order of 100 ms can be tolerated with optional behaviour for shorter latency.
3.3 ISA100 objects
ISA100.11a defines a communication protocol, with an application layer that
includes a simple but extensible set of input and output objects.
The GS01 detector publishes the measured values and diagnostic information as
ISA100 objects with attributes. It is distinguished between standard attributes and
GS01 device specific attributes.
3.3.1 Standard objects
The GS01 publishes ISA100 standard objects with attributes for process value
and diagnostic status as outlined in Table 3-1 below. The gas measurement value

GasSecure GS01
Hardware Manual
COMMISSIONING
13
is sent as User Application - Analog Input Object with the attribute “Process Value”
(PV). Note that the user may choose which gas configuration to read out by
selecting the corresponding PV object (Methane or Propane) for publication. The
device health information is compiled and sent as User Application Management
Object with the attribute “Diagnostic Status” (DIAG_STATUS).
The concentrator of the gas detector is per default set up to publish the gas
measurement and the diagnostic status. The concentrator can be configured
differently in the gateway interface.
For short detector response time (<5 sec as per GS01 datasheet), the gateway
must be set up with a 2 sec sampling interval (also referred to as publication
period). In the absence of hydrocarbon gas, the detector will not publish on all
available time slots, but per default only publish on every 6th time in order to save
battery power. In the presence of hydrocarbon gas of sufficient concentration
(defined by the internal low alarm limit see Table 8-1), all time slots will be used.

The full mapping of the content of the DIAG_STATUS attribute is explained in
Table 10-2 in the Appendix.
Note that a controller is required to display the diagnostic information including
fault or alarm conditions.
Recommendations for which status and diagnostic information to integrate in the
control and maintenance loop are also provided in the Appendix.
3.3.2 GS01 specific objects for safe communication
In addition to the standard objects, the GS01 can be configured to publish and
subscribe to the custom data object “SafeData”. This object is used for safe

GasSecure GS01
Hardware Manual
14 CHAPTER 3
communication. The GS01 uses the PROFIsafe profile over PROFINET as tool for
safe communication. In this setup the GS01 acts as F-Slave, a passive
communication peer able to perform PROFIsafe. Its counterpart is the F-Host, a
data processing unit able to perform PROFIsafe and to trigger the F-Slave for data
exchange. The F-Host must be compliant with the PROFIsafe requirements so
that end-to-end communication through a black channel, defined by the IEC
61508 standard, can be established.
Please refer to the GS01 safety manual [RD 9] for further information on how to
set up safe communication with PROFIsafe. For applications without PROFIsafe
the “SafeData” object shall be disregarded.
3.4 GS01 data format details
The GS01 data objects can be mapped into 16 bit Modbus input registers.
The “PV” object (cf. Section 3.3.1) normally populates three registers; the
PV_Status byte populates the last 8 bits of the first register and the 32 bit float
number populates the following two registers.
The “UAPMO.DIAG_STATUS” object (cf. Section 3.3.1) is normally mapped into
two 16 bit registers. Some gateways will also add a status byte into the preceding
register. This status byte may be ignored, because its information is already
contained in the PV_status byte.
The procedure for Modbus register mapping depends on the specific gateway,
please consult the respective gateway manual on how to achieve this mapping.
GasSecure can assist with advice if needed.
3.5 Modification of LEL
Regionally different conversion factors may apply for the display of measured
concentrations in percent of the lower explosion limit (LEL). The GasSecure GS01
gas detector allows you to select one of two LEL categories, which basically
correspond with common explosion limits in the USA (NIOSH Pocket Guide to
Chemical Hazards4) and Europe IEC 60079-20), cf. Table 3-2. The factory default
setting is LEL according to IEC. The LEL category may be changed with the GS01
Configurator tool as part of device provisioning as explained in Section 3.7.
Note that this feature is supported for GS01 firmware version ≥3.3.

3.6 Communication monitoring
The PV_Status byte (see Table 3-1) can be used for monitoring the
communication status and the data integrity. See Table 10-1 in the Appendix for
all details. With no error present (e.g. beam block or critical low power) and the
detector communicating with the gateway, the status byte will be decimal value 64
or higher; please refer to Table 3-3 below for the three main classes of data
integrity.
The status byte is updated by the gateway if the communication with the detector
is lost. The time from reception of the last packet and until the status byte is
updated to flag “lost communication” is defined via the stale limit parameter.
Please consult the gateway manual for information about setting this stale limit.
GasSecure’s recommendation is a sampling interval of 2 sec (see Section 3.3.1)
together with a stale limit of 30 times, so that “lost communication” is flagged after
maximum 60 sec. Under no circumstances the stale limit must be set to less than
6, because this would disable communication between detector and gateway.
Note that the timeout, as defined by the stale limit, can be checked by removing
the battery and monitoring the time until the PV_Status byte is updated.

3.7 GS01 detector provisioning
All GS01 detectors have to be provisioned so that they will join the correct
network. Provisioning the GS01 requires the following:
•The GS01 serial adapter together with the GS01 Configurator software
(both accessories from GasSecure)
•FTDI virtual comport driver for the GS01 serial adapter
•The network (or subnet) ID of the gateway or backbone router
•For Yokogawa gateway only: A Capability File (CF) for the GS01 device.

GasSecure GS01
Hardware Manual

Software tools, drivers, and files (e.g. CF) are available for download at
http://tools.gassecure.com.
This procedure can be carried out with an unprovisioned GS01 or with a GS01
that earlier has been provisioned to another gateway.
3.7.1 Yokogawa gateways
a) Connect the GS01 to a PC with the GS01 Configurator installed using the
GS01 serial adapter.
b) Run the GS01 Configurator and select the correct COM port. Keep the
default mode “Provision one GS01 device”. Press the “Connect” button and
verify that the device information is displayed, cf. Figure 3-1. Press the
“Read version info” button if the device information does not show
automatically. Press the “Read” button so that the current provisioning
status of the device is displayed.
c) Enter the device tag and the required network ID in decimal format, cf.
Figure 3-1.

i. Specific (user-defined) join key: Type a 32-bit hexadecimal number
in the “join key” field.
ii. Generate a random join key: Press the “Generate random join key”
button.
e) Check and set the LEL category to either IEC or NIOSH as defined in Table
3-2.
f) Check the destination folder for the ypif file and change it by pressing the
“...” button if necessary. Press the “Generate ypif file” button. This file must
be uploaded to the gateway (explained in reference [RD 4]) to enable
communication. Press the “Apply” button (do not make any changes to the
provisioning input data between pressing the two buttons!).
g) Close and exit the GS01 Configurator and disconnect the GS01 detector
from the PC.
h) Power up the GS01 by inserting the battery pack.
i) The GS01 device should join the network within 5-20 minutes, if it is within
radio distance to the gateway and the gateway is set up properly (refer to
reference [RD 4]). If the gateway is out of radio range, the GS01 device will
try to connect for a period of 60 min and then enter a power-saving mode.
In this mode it will try to connect for a 5 min period once per hour.
