Zone 1 for gases and 2D Zone 21 for dusts The exact range of application can be found on the label of the device Special conditions for application safety and instructions for using the device The dimensions of the flameproof joints are in parts other than the relevant minimum or maximum values of IEC 60079 1 2007 For information on the dimensions of the flameproof joints contact the manufacturer The enclosure has to be integrated into the potential equalisation of the machine to be monitored this can be done either via the fastenings or via the connecting terminal The installer has to ensure that the equipotential bond is established by a qualified specialist in accordance with the relevant VDE regulations Lead in and connection cable The free cable end of the vibration monitor has to be connected either in an enclosure in one the types of protection stated in sec 1 of IEC60079 0 2007 or outside the explosive atmosphere The open end of the supply cable must be connected in accordance with current wiring regulations In applications in Zone 21 it must be ensured when installing the connection cable that electrostatic charging cannot lead to ignitable discharges The lead in and the connection cable are supplied with the device and are certified for the above mentioned application range for a minimum temperature resistance from 60T to 90 and comply with the requirements of the appli cable installation regulations Connection2. cable Caution The device must never be transported suspended from the connecting cable It is not permitted to change the connection at the device or to change the cable Since the lead in does not have its own cable relief the connecting cable must be fixed by the user in the proximity of the lead in within a radius of approx 20cm The fixing must be executed in such a manner that the cable has no kinks and it is not damaged General points to be observed The operator installer has to find out the Ex regulation applicable for his her area of application and comply with the same The temperature specifications refer to values without pouring When pouring the installation conditions should be observed The supply voltage must be power limited components and executed according to the applicable Ex provisions Electronic Vibration monitoring Unit i holthausen ESW small Ex Transmitter elektronik GmbH 7 Grounding concept main control box with power supply optional vibration i bratio connection box control unit _ Shield signal ground Sie i F main control vibration control unit ground connection box ground l box ground v Vv Vv local ocal loca vibration control unit ground connection box ground main control box ground If an isolated installation is not specially requested usually through the attachment with screws each case is connected to the local machine ground In big facilitie
3. principle The vibration monitoring unit is generally mounted on the place where inadmissible vibration occurs or can be expected The unit is permanently monitoring the real condition or situation on the machine The noticed mechanical vibration detected by the sensor will be transformed to a corresponding electrical signal The sensor converts mechanical oscillations into an electrical alternating voltage The subsequent electronics converts the AC signal into a DC voltage which is equivalent to the measured oscillation speed A current in the range 0 to 20mA or 4 to 20mA or a voltage in the range 0 to 10V which is proportional to the measured value and corresponds to the measuring range is delivered over the analog output cable terminals 5 Connection technology The ESW small Ex Transmitter is available in two different basic versions Conventional technique This version is designed in such a way that two conductors are used for power supply and two conductors are used for the analog output Two conductor technique Although the term is defined there are various interpretations of the same In order to avoid misunderstanding a brief description of the use of the device is given below A Voltage is measured across the load resistance which is proportional to the current and thus to the measured value Load resistance Supply O Voltage signal B The current is measured using an ammeter e g SPS whic
