WARNING
BEFORE installing, using or carrying out any maintenance tasks associated with this instrument, READ
THE INSTRUCTIONS CAREFULLY.
These instruments comply with the essential safety requirements of the European Directive ATEX 94/9/CE. It is certified
to be used in Gas or Dust explosive atmospheres, groups IIA, IIB, IIC or IIIC:
Category II 1GD – zones 0, 1, 2, 20, 21 and 22 for the protection mode "ia"
Category II 3G – zone 2 for the protection mode "nA & nL"
Category II 2GD – zones 1, 2, 21 and 22 for the protection mode "d".
They also comply with the essential safety requirements of the European Directive EMC 89/336/CE as amended, for use
within an industrial environment.
It is the end user's responsibility to:
Verify material compatibility with the application
Ensure proper use of fall protection when working at heights, per Safe Site Work Practices
Ensure use of proper Personal Protective Equipment
Take the appropriate actions to ensure that site personnel who are performing installation, commissioning and
maintenance have been trained in proper site procedures for working with and around equipment, per Safe Site
Work Practices
Products certified as explosion proof equipment MUST BE:
a) Installed, put into service, used and maintained in compliance with European and/or national and local
regulations and in accordance with the recommendations contained in the relevant standards concerning
potentially explosive atmospheres.
b) Used only in situations those comply with the certification conditions shown in this document and after
verification of their compatibility with the zone of intended use and the permitted maximum ambient
temperature.
c) Installed, put into service and maintained by qualified and competent professionals who have been trained in
proper site procedures for for instrumentation used in areas with potentially explosive atmosphere and for
working with and around equipment, per Safe Site Work Practices.
Under certain operating conditions, the use of damaged instruments could cause a degradation of the performances of
the system which may lead to personal injury or death.
Use only genuine replacement parts, which are provided by the manufacturer, to guarantee that the products comply
with the essential safety requirements of the European Directives mentioned above.
INSTRUMENT OPERATION
4700E/4800E apparatus: electro pneumatic positioner (force balanced principle) with integrated current to pressure
converter (4000 I/P Converter). It controls the position of the plug of a control valve to a 4-20 mA control signal.
Feedback is obtained by means of a cam.
4800E is a positioner with a high flow pneumatic block.
