PTZ-BOX 5.0 User manual, document edition: 13
22
The function and parameters of some inputs/outputs depend on version of product,
detailed information is written herein.
The unit should not be installed in the vicinity of strong electromagnetic fields.
Only devices with the same serial number on the name plate on the housing cover and
electronic name plate (displayed on LCD) are allowed.
PTZ-BOX 5.0 can be ordered to be complied of the requirements of the Measuring
Instruments Directive 2014/32/EC of European Parliament and Council (MID) which apply
to volume conversion devices intended for residential, commercial and light industrial use.
The PTZ-BOX 5.0 compliant with MID, on t
he name plate, next to the “CE” sign has the
supplementary metrology marking consists of: capital letter “M” followed by last two
digits of the year of its affixing, surrounded by a rectangle.
According to MID directive it is permissible to use terminal boxes, surge suppressors and
Zener barriers in systems of measurement circuits. It is required that these components
were designed for sealing.
To connect PTZ-BOX 5.0 with gas meter or transducer, it is necessary to use cables
appropriate with used in gas meter or transducer cable glands. Before installing always
refer to the technical documentation of gas meter/transducer, which should contain a
detailed information about conditions and methods of installation, types of wires etc.
PTZ-BOX 5.0 can be ordered with GSM or NFC functionality, such device becomes a radio
equipment and fulfills the requirements of the Directive 2014/53/EU of the European
Parliament and of the Council of 16 April 2014 on the harmonisation of the laws of the
Member States relating to the making available on the market of radio equipment and
repealing Directive 1999/5/EC (RED).
Use of the device is only possible where working GSM module does not interfere with
the operation of other equipment (e.g. medical).
Connection of measurement circuits LF, HF, Encoder and digital inputs:
The intrinsically safe circuits shall meet all conditions for intrinsically safe circuits
specified in EN 60079-14, and in particular:
•
For intrinsically safe measuring circuits connect cables with separated two wires
or use multi-core type A or type B cables according to point 12.2.2.8 of directive
EN 60079-14.
•
Cables and wiring of intrinsically safe circuits must be kept separate from the
cables and wires of non-intrinsically safe circuits.
•
Cables and wiring of intrinsically safe circuits should be permanently mounted and
protected from the possibility of mechanical damage.
•
Cables of intrinsically safe circuits are recommended to be marked with blue color.
•
Connect the cable shield to the housing gland. This way grounding of the cable
shield of intrinsically safe circuits will occur at one point
–
next to PTZ-BOX 5.0
device. During use of measuring transducers, cable shield should be insulated.
