have been authorised to do so by the plant operator. The skilled personnel must read this manual and follow the instructions contained in it.
The installer must make sure that the measurement system is connected
following the electrical connection diagrams. Changes and repairs on
the unit must only be done if the manual shows these to be possible.
Always take note of the national electrical safety regulations when opening or repairing electrical units.

2.3Certification
CE mark, conformity certification
The unit has been manufactured using state-of-the-art technology and
has left the factory in perfect working order. The unit complies with
relevant regulations as well as the IEC 61010 “Safety regulations for
measurement, control and laboratory instrumentation" directives.
This means that the unit described in this operating manual
fulfils the legal requirements laid down in the EU directives. The manufacturer acknowledges successful testing of the unit by adding the CE
mark to it.
3 Operation and system construction
3.1Measurement principle
The field mounted display is directly connected to a 4 to 20 mA current
circuit. The energy required to power the unit is derived from the current loop. The unit monitors an analogue measured value and shows
this on an easily read LC display. Additionally, the measured value is
also shown in the form of a bargraph.
Increased readability in dark areas is achieved by the addition of a illuminated display.
3.2System construction
Micro-controller controlled field mounted display with rear illuminated
numeric and analogue LC display. Display update is made every second.
The dynamic internal resistor (load) makes sure that the signal circuit
voltage drop is always < 2.5 V.

5.1.2 Electrical connection
Both the terminal layout and the connection values of the field mounted
display conform to the Ex requirements.
The unit is only meant for use in a 4 to 20 mA current loop circuit.
Potential equilibrium must be guaranteed on the current loop (inside
