1 DESCRIPTION AND DEFINITIONS
1.1 Scope of this manual
This manual provides installation, operation and routine maintenance instructions for
the 05311B1 OxyDetect - Oxygen Deficiency Fixed Gas Detector, abbreviated to
"instrument" or “unit” in the remainder of this manual.
1.2 Safety information
Read this manual and ensure that you fully understand its content before you attempt
to install, use or maintain the instrument. Important safety information is highlighted in
this manual as WARNINGs and CAUTIONs, which are used as follows:
Warnings highlight specific hazards which, if not taken into
account, may result in personal injury or death.
Avertissements soulignent les dangers spécifiques qui, si pas
pris en compte, peut entraîner des blessures ou la mort.

1.3 Description
The Instrument is a fixed wall mounted gas detector with an integral oxygen sensor
that outputs a linear 4-20mA signal that represents an ambient oxygen concentration.
Additionally, three changeover relays are provided to signal the following detector
statuses.
Measurement alarm level 1 (user configurable)
Measurement alarm level 2 (user configurable)
Instrument Fault and Oxygen measurement >23%
These outputs must be integrated into a gas detection management system as the
instrument gives no direct visible or audible warning or alarm of an oxygen-deficient
environment (internal audible alarm or visual beacon), its function being solely to
measure the ambient level of oxygen. It offers a measurement of ambient oxygen
based on the principles of paramagnetism, a non-depleting and inherently linear
measurement technique.
The instrument is designed to be installed within indoor working environments such
as laboratories, workshops or analyser shelters.
Gas sample measurements are shown on the instrument display, and can be output
as a 4-20mA milliamp (mA) signal and / or gas sample alarm levels indicted by relay
status, to a gas detection management system.
The instrument requires little routine maintenance, other than calibration which is
essential for the accuracy of the gas measurements.
The instrument is not to be used for process control or process
monitoring
L'instrument ne doit pas être utilisé pour le contrôle des
processus ou la surveillance de processus
The OxyDetect is not a medical device as defined in the medical
devices directive 93/42/EEC and is not intended to be used on
human beings for the diagnosis, prevention, monitoring,
treatment or alleviation of disease. Injury or replacement or
modification of the anatomy
Le OxyDetect est pas un dispositif médical tel que défini dans
les dispositifs médicaux de la directive 93/42 / CEE et ne sont
pas destinés à être utilisés sur des êtres humains pour le
diagnostic, la prévention, contrôle, traitement ou atténuation
d'une maladie. Blessure ou de remplacement ou modification de
l'anatomie.

OxyDetect Oxygen Deficiency Gas Detector 1 – Description and definitions
05311001B / Revision 4 3
The safe area version is not to be used in certified or hazardous
locations (potentially explosive atmospheres)
La version de zone de sécurité ne doit pas être utilisé dans des
endroits certifiés ou dangereux (atmosphères explosibles)
The instrument is not suitable for corrosive atmospheres (those
atmospheres where gases and vapours are present in
concentrations high enough to cause corrosion to normal
industrial appliances or where specialised coatings, materials or
finishes would normally be specified to avoid corrosion)
L'instrument ne convient pas pour les atmosphères corrosives
(ces atmosphères gaz et les vapeurs sont présents dans des
concentrations suffisamment élevées pour provoquer la
corrosion des appareils industriels ou normales où devraient
normalement être précisées revêtements spécialisés, des
matériaux ou finitions pour éviter la corrosion)

1.5 Certification
1.5.1 Hazardous area certification
Do not modify the unit, either mechanically or electrically, as the
certification of the instrument will be invalidated and it may not
operate safely.
Ne modifiez pas l'unité, soit mécaniquement ou électriquement,
ou la certification de l'instrument sera invalidée et il ne peut pas
fonctionner en toute sécurité.
Hazardous area certification is restricted to the use of the unit in
atmospheres at normal oxygen concentration and normal
atmospheric pressures. The oxygen measurement range for
hazardous area versions is 0 to 21%.
Certification de zone dangereuse est limitée à l'utilisation de
l'appareil dans des atmosphères à la concentration d'oxygène
normale et des pressions atmosphériques normales . plage de
mesure de l'oxygène pour les versions en zone dangereuse est
0 à 21 %.

 The OxyDetect enclosure is designed such that it achieves
IP66 ingress protection. However, in operational use
consideration must be made for the protection of the sensor
opening which is rated to IP40. Therefore, the instrument should
not be exposed to washing with liquid jets. The instrument is for
indoor use only.
 L'enceinte OxyDetect estconçue de telle sorte qu'elle réalise
IP66 protection d'entrée. Cependant, dans l'utilisation
opérationnelle examen doit être fait pour la protection de
l'ouverture du capteur qui est évalué à IP40. Par conséquent,
l'instrument ne doit pas être exposé à un lavage avec jets de
liquide. L'instrument est destiné à être utilisé en intérieur.
If the ambient temperature falls below 0 °C (32 °F) the instrument
should be recalibrated to ensure correct operation.
Si la température ambiante descend en dessous de 0 °C (32 °F)

The instrument user interface comprises the following (shown on Figure 1):
Display Shows various screens: see Section 5.2 onwards
Soft keys The function of each of the soft keys depends on the screen
currently being shown on the display: see Section 5.2
Alarm LED On when an alarm condition exists: see Section 6.5
Fault LED On when a fault condition exists: see Section 9.1
5.2 Start-up and measurement screens
When you first switch on the instrument, a 'start-up screen' is displayed while the
instrument carries out a self-test.
The start-up screen shows the Servomex name, a 'self-test time elapsed/remaining'
indicator, and messages identifying the tasks being carried out as part of the self-test.
The screen will initially display the "System Check" task message. The measurement
screen is then displayed, as shown in Figure 6 below.
