Certification
The CE marking is a mandatory conformity marking that allows the manufacturers
to circulate (industrial) products freely within the internal market of the European
Economic Area (EEA). The CE mark self-certifies that the products have met the
minimum EEA health, safety and environmental requirements for the consumer and
workplace safety.
The CE marking is also found on products sold outside the EEA that are manufactured
in, or designed to be sold in, the EEA.
The WEEE/RoHS Directive uses a special logo in addition to the CE logo to show
that the product is designed and manufactured to restrict the release of the hazardous
substances from the electrical and the electronic equipment to prevent major envi-
ronmental and health problems.

3 Safety information
3.1 Work safety
3.1.1 Mechanical work
Only qualified and well-trained persons who are familiar with the mechanical installation and the
service procedures and who obey the specific regulations and the requirements set by the authorities,
the manufacturer, the employer and the plant owner, are allowed to do the mechanical work.
3.1.2 Electrical work
Only qualified and well-trained persons who are familiar with the electrical installation and the service
procedures and who obey the specific regulations and requirements set by the authorities, the
manufacturer, the employer and the plant owner, are allowed to do the electrical work.
3.1.3 Operation and setup
Only qualified and well-trained persons who are familiar with the operation and setup of the B-Basic
and the related installation and who obey the specific regulations and requirements set by the
authorities, the manufacturer, the employer and the plant owner, are allowed to do the setup and
to operate the B-Basic.
3.2 General electrical safety
Electricity can cause (serious) injury to persons and cause damage to equipment. Many accidents
cause serious electrical shock or serious burns. Fatal shocks are often caused by high voltage
systems. But even non-fatal electrical shock causes (serious) injury to persons by falls from ladders.
Typical hazards from work with electrical powered systems are:
•the contact with live parts that cause electrical shock;
•failures that can cause a (electrical) fire;
•the fire or explosion caused by electrical failures.
Work safely on the electrical installations:
1Understand and know the construction and circuits of the (electrical) installation and equipment.
2Make sure, the tools, materials and equipment are calibrated, valid and suitable for the work.
3Identify the possible energy sources that can cause a hazard.
4Lock Out / Tag Out the (related) installation.
5Measure the voltage.
6Make sure, the reading is 0 Volt to prove that the installation is safe to work on!
7At any time, if the work becomes more hazardous than anticipated for, stop and take the required
(safety) precautions.
3.3 Battery power related safety
WARNING!
Handle the battery with care. A mistreated battery can become unsafe. Unsafe
batteries can cause (serious) injury to persons.
The batteries are used to store electrical energy. The battery is a high power battery which must be
treated carefully. When the battery is mistreated or damaged, there is a risk of a fire, an explosion
and serious burns.
1Only use a battery which is applicable for the intended use.
2Mind that you cannot switch off a battery.
3Make sure, it is safe to work on the battery system.

4Handle the battery with the utmost care to prevent a short circuit and damage.
5Do not recharge, crush, disassemble, incinerate, heat above its rated temperature or expose the
contents to water.
6Dispose of the battery in accordance with the (inter)national, the manufacturer’s and the plant
owner’s standards and regulations.

also supply the backlight.

USER GUIDEB-SERIES B-BASIC

SENSOR EXCITATION
This voltage shall not be used to supply the flowmeter's electronics, converters
etc., as it will not provide adequate sustained power! All energy used by the
flowmeter's pick-up will directly influence the battery life-time. It is strongly ad-
vised to use a 'zero power' pickup such as a coil or reed-switch when operating
without external power. It is possible to use some low power NPN or PNP
output signals, but the battery life time will be significantly reduced (consult
your distributor).
