1 Safety
Ensure that this operation manual is read and understood BEFORE
installing/operating/maintaining the equipment. Pay particular attention
to "Warnings" and "Notes". All the document Warnings are listed here
and repeated where appropriate some of the start of relevant chapter(s)
of the manual. Notes appear in the corresponding parts of each chapter
where they apply.
WARNINGS
RAEGuard 3 is designed for installation and use in Zone 1, Zone 2 hazardous areas in many
countries including Europe, China etc.
Installation must be in accordance with the recognized standards of the appropriate authority in
the country concerned.
Access to the interior of detector, when carrying out any work, must only be conducted by trained
personnel.
Before carrying out any work ensure local regulations and site procedures are followed.
Appropriate standards must be followed to maintain the overall certification of the detector.
Two cable entries must be fitted with “seal fitting” appropriately, such as conduits, stopped plug,
cable gland etc. For installation where conduit is used, there must be a “Seal fitting” installed for
each of the cable gland entries within 150cm of RAEGuard 3. The total distance of location of
these Seal Fitting is 150cm. (e.g. If all 3 gland entries are to be used, 3 Seal Fittings should be
located, each within 50cm of the wiring entrance).
If using anti-seize compound, they should not contain substances that may poison or suppress
the catalytic flammable gas sensor, such as silicides, sulfides, chlorine, lead, or halogenated
hydrocarbons.
To reduce the risk of ignition of hazardous atmosphere, de-classify or disconnect the equipment
from the supply circuit before opening the detector enclosure. Keep assembly tightly closed
during operation.
Never attempt to open a junction box/enclosure or replace/refit flammable-gas/infrared sensor in
potentially hazardous atmospheres while the transmitter is energized.
The detector must be earthed/grounded for electrical safety and to limit effects of radio frequency
interference. Earth/ground points are provided inside and outside the unit. The internal grounding
shall be used the primary equipment ground. The external terminal is only a supplemental
bonding connection where local authorities permit or require such that.
Ensure that all screens/instrument earth/clean earth wiring is earthed/grounded at a single point
(either at the controller or detector-BUT NOT BOTH) to prevent false reading or alarms that may
occur due to potential earth/ground loops.
Take care when handling sensors as they may contain corrosive solutions.
Do not tamper with or in any way disassemble the sensor.
Do not expose to temperature outside the recommended ranges.
Do not expose sensors under storage conditions to organic solvents or flammable liquid.
When the service life of the sensor expires, the discarded sensors must be stored in a safe
environment to prevent environmental pollution. Or hand it to Honeywell for proper disposal.
Electrochemical sensors should NOT be incinerated as this action may cause the cell to emit toxic
fumes.
The sensor head must be fitted with the supplied waterproof cap, and mounted so that overall
detector meets ingress protection rating.
Modbus, Hart, menu, and Bluetooth cannot be used to set up the instrument at the same time.

Special condition for safe use:
1. Compliance with the manual is required for safe use of RAEGuard 3.
2. Once the instrument steps into the "safe state", must shut down and
resume detector until it is ensured to be good.
3. Once the instrument will be under "safe state", 4-20mA current loop
output will output a constant value, no further changes along with
environmental gas concentration.
4. RAEGuard 3 has been calibrated by regular gas in factory before
dispatched, but in order to ensure the sensitivity and accuracy of the
instrument as far as we can, it is recommended that shall be calibrated
by complied gas each 6-month at least, also must use the “Calibration
cap” for calibration process.
5. In wiring, due to unexpected factors in the environment, the 4-20mA
output circuit may be attenuated. Checking and if not corresponding,
please re-calibrate 4mA and 20mA after the instrument is installed.
6. High and Low Alarm default threshold value are experience, and they
can be reset depending on the field applications or the demands of
customer or local regulatory. (This function is optional, if no ordering,
no offering).
7. Be Careful of low and high alarm trigger set. If the trigger set in menu
is FALLING, the device will not send an alarm message even if a high
concentration gas leak is detected!
8. Both STEL and TWA are nearly used in portable to protect personal
safety working in hazardous environments for a long time. Default is set
to DISABLE.
9. The CF set in menu is only enabled for catalytic sensor and non-
dispersive infrared sensor for detection of flammable gas.
10. For Oxygen sensor, customer in the field only needs to do SPAN
calibration since its zero calibration has been completed at the factory.
11. For oxygen sensor, while the concentration of detector is in the range
of 20.5%vol to 21.3%vol under normal status, the concentration on LCD
will show 20.9% vol. If concentration is in the range of - 1%vol to 0%vol,
detector shows 0% vol, and the output is 4 mA.
12. For flammable gas, in normal measurement, when the measured value
of detector is in the range of - 10% LEL to 1% LEL, the concentration
will show 0% LEL and output 4 mA.

2 Introduction
The RAEGuard 3 consists of a gas detector transmitters and a choice of sensors
for detecting flammable gas, toxic gas and oxygen. It is designed for using in
hazardous area locations and may also to be used in other area not classified as
hazardous.
Toxic gas and oxygen sensors adopt intrinsically safety design to allow users to
modify the range, enriching and expanding the use scenario and detection range
of one detector, and support hot swap in the field, which greatly facilitates user
maintenance and expansion.
The transmitter features a large-screen graphic LCD display and three
programmable relays as option for controlling external equipment e.g. alarms,
sirens, valves or switches. It provides an industry standard 3-wire, 4-20mA analog
source output and Modbus RTU digital signal output for connection to a dedicated
gas detection control system or PLC.
Calibration and maintenance is carried out using a magnetic wand via 3-button,
which allows a single person to undertake routine practice with non-intrusive to
detector inside.
And modular design can expand Visible and Sound Alarm (SP-07 only for China),
HART, Surge Protection Device, BLE Bluetooth and so on.
In addition, more accessories/spares such as Collecting cone, Sunshade/Deluge
Protection, Duct Mount Kit, Gas-flow Adaptor, Mounting Plate Kit as well as
various Cable Glands as option offered can be used for more applications.
RAEGuard 3 is suitable for use in Zone 1 or 2 hazardous areas(International and
China).
