Safety Information
FOR SAFETY REASONS THIS EQUIPMENT MUST BE OPERATED AND SERVICED BY QUALIFIED
PERSONNEL ONLY. READ AND UNDERSTAND INSTRUCTION MANUAL COMPLETELY BEFORE
OPERATING OR SERVICING.
CAUTION
A HIGH OFF-SCALE READING MAY INDICATE EXPLOSIVE CONCENTRATION.
Observe these precautions:
To minimize the risk of electrostatic charge, provision shall be made for adequate grounding and
•
equipment shall be installed in such a manner so that accidental discharge shall not occur.
When Prosense SAFEVADER reaches the end of its life, it should be disposed of in accordance
•
with local regulations.
Do not use cleaning solvents or abrasives to clean the gas detector.
•
•
Do not attempt to modify the product in any way from the manufacturers design or
specification. Warranty will be void and malfunction of the gas detector may result.
•
Use only genuine spare parts and accessories with Prosense SAFEVADER. Malfunction may result
if non-standard parts are used.
WARNING
•
Prosense SAFEVADER is designed for installation and use in safe areas.
Installation must be in accordance with the recognized standards of the appropriate authority in
•
the country concerned.
•
Access to the interior of the 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.
•
In order to maintain electrical safety, the product must not be operated in atmospheres with more
than 21% oxygen. Oxygen deficient atmospheres (Combustible: less than 10%V/V, Toxic: less than
6%V/V) may suppress the sensor output.
•
Never attempt to open the enclosure or replace/refit the sensor in potentially hazardous
atmospheres or while power is still applied to the transmitter.
•
The detector must be earthed/grounded for electrical safety and to limit the effects of radio
frequency interference. Earth/ground points are provided inside the unit. The internal grounding shall
be used as the primary equipment ground.
•
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 readings 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 temperatures outside the recommended ranges.
•
Do not expose sensors under storage conditions to organic solvents or flammable liquids.
•
At the end of their working life, replaceable electrochemical sensors for oxygen and toxic gas must
•
be disposed of in an environmentally safe manner. Disposal should be according to local waste
management requirements and environmental legislation.
