2 Safety

2.1 Explanation of safety symbols

DANGER

This symbol warns of imminent danger, which can result in death, severe bodily injury,

or severe property damage in case of non-observance.

CAUTION

This symbol warns of potential dangers or harmful situations, which can cause damage

to the device or to the environment in case of non-observance.

NOTE

This symbol indicates processes, which can have a direct influence on operation or

can trigger an unforeseen reaction in case of non-observance.

2.2 Foreseeable misuse

The fault-free function and operational safety of the product can only be guaranteed if

applicable safety precautions and the device-specific safety instructions for this docu-

ment are observed.

If these notices are disregarded, personal injury or death, as well as property damage

can occur.

DANGER

Incorrect area of application!

In order to prevent erratic behaviour of the product, personal injury and property

damage, the product must be used exclusively as described in the chapter Description

in the operating manual.

–Do not use in safety / emergency stop devices!

–The product is not suitable for underwater use (rebreather)!

–The product is not permitted as the sole measuring device for controlling sub-

mersible gas mixtures - The fundamental safety of the gas mixture must be en-

sured, for example, by calculating the pressure ratios during filling or by safe

membrane filter systems or comparison with safe references!

–The product is not suitable for use in explosion-prone areas!

–The product must not be used for diagnostic or other medical purposes on pa-

tients!

2 | Safety G 1690 / G 1690T

6 / 20 B-H86.0.31.DK2-1.0

–Not suitable for use with requirements on functional safety, e.g. SIL!

–This device only serves as supervision by the monitoring of essential or other for

the customer important systems. It must not be used instead of compulsory ap-

proval monitoring devices and it is not designed for that purpose. If this device is

used for the monitoring of such systems on its own, the manufacturer will not as-

sume liability for damages whatsoever

2.3 Safety instructions

DANGER

Use caution when handling oxygen at levels above 40 vol. % O2- high oxygen levels

can cause ignition of materials and explosion if not handled properly

NOTE

This device does not belong in children's hands!

DANGER

The sensor contains potassium hydroxide (GOEL 381 at G 1690..-MAX) or acid

(GOEL 370 at G 1690..-35).

Potassium hydroxide and acids cause chemical burns!

In case of leaking liquid, avoid contact at all costs!

In case of contact:

•with skin: wash off immediately with plenty of water for several minutes.

•with clothing: remove contaminated, soaked clothing immediately.

•with eyes: rinse under running water for several minutes, consult a doctor.

If swallowed:

•drink plenty of water immediately, do not induce vomiting!

•Consult a doctor.

2.4 Intended use

The device is to be used exclusively for measuring the oxygen concentration in gas

mixtures and air. The measurement is made at the sensor opening.

The device must be calibrated regularly (in fresh air =20.95% vol.-% O2) to obtain

accurate readings.

The G 1690T is also suitable for displaying the calculated maximum operating depth

(MOD) from the measured oxygen concentration.

G 1690 / G 1690T Safety | 2

B-H86.0.31.DK2-1.0 7 / 20

For the MOD display, only air and NITROX mixtures with an oxygen concentration be-

tween 20.9 ... 36.0 vol. % O2may be used as dry gases!

DANGER

For safe measurements, the function of the sensor and device must be checked

regularly:

- Regular calibration on ambient air (20.9 vol. % O2) in accordance with the instruc-

tions

- In the case of higher oxygen values, check the function with a known gas concentra-

tion, preferably in the area of the gas to be measured (e.g. pure oxygen, NITROX50

or similar, "bump test")

DANGER

The MOD function (calculated maximum operating depth for diving) is designed only

for use in recreational diving from 20.9 to 36.0 vol. % O2.

It does not replace necessary calculations and application of the rules for planning and

performing a safe dive according to NITROX training.

DANGER

The MOD function is not designed for depth calculation of gas mixtures other than

those mentioned above (no "tech-diving", NITROX50, TRIMIX, …).

Any use of the de-vice in this area requires appropriate training and additional safety

measures.

NOTE

The device is only intended for use within the region of the European Union (EU).

2.5 Qualified personnel

For commissioning, operation and maintenance, the relevant personnel must have

adequate knowledge of the measuring process and the significance of the measure-

ments. The instructions in this document must be understood, observed and followed.

In order to avoid any risks arising from interpretation of the measurements in the

concrete application, the user must have additional expertise. The user is solely liable

for damages/danger resulting from misinterpretation due to inadequate expertise.
