Operation instruction for Explosion protected control
panels
Application and Standards
This instruction manual applies to explosion protected control panels of type of protection
types below. This apparatus is only to be used as defined and meets requirements of EN 60
079 particularly EN60 079-14 "electrical apparatus for potentiality explosive atmospheres". It
can be used in hazardous locations which are hazardous due to gases and vapours according
to the explosion group and temperature class as stipulated on the type label. When installing
and operating the explosion protected distribution and control panels the respective nationally
valid regulations and requirements are to be observed.
General Instructions
The control panel has to have a back-up fuse as stipulated. The mains connection must have
a sufficient short circuit current to ensure safe breaking of the fuse. To achieve an impeccable
and safety device operation, please take care for adept transportation, storage and mounting,
as well as accurate service and maintenance. Operation of this device should only be implemented by authorised persons and in strict accordance with local safety standards. The electrical data on the type label and if applicable, the "special conditions" of the test certificate PTB
98 ATEX 1488 are to be observed.
For outdoor installation it is recommended to protect the explosion protected distribution and
control panel against direct climatic influence, e.g. with a protective roof. The maximum ambient temperature is 40°C, if not stipulated otherwise.
Intrinsically Safe Circuits
Erection instructions in the testing certificates of intrinsically safe apparatus are to be observed. The electrical safety values stipulated on the type label must not be exceeded in the
intrinsically safe circuit. When interconnecting intrinsically safe circuits it is to be tested,
whether a voltage and/or current addition occurs. The intrinsic safety of interconnected circuits
is to be ensured. (EN 60079-14, section 12)
Safety Measures: to read and to comply
Work on electrical installations and apparatus in operation is generally forbidden in hazardous
locations, with the exception of intrinsically safe circuits. In special cases work can be done on
non-intrinsically safe circuits, on the condition that during the duration of such work no explosive atmosphere exists. Only explosion protected certified measuring instruments may be
used to ensure that the apparatus is voltage-free. Grounding and short circuiting may only be
carried out, if there is no explosion hazard at the grounding or short circuit connection.

Digital Indicator D 122.A
2.1
Short description
Page 4
The digital Indicator D122 indicates measured values of intrinsically safe current circuits from
4 up to 20 mA in hazardous areas. The device is powered by measure current, therefore an
extra power supply or batteries are unnecessary. The indicator measures the current, scales
the measured value and displays finally the result on the LCD.
For trend analysis, the measured signal is also be displayed on a 41 segment bargraph. It's
possible to scale the bargraph separately to the digital value. The indicator D122 is available
in several housings.
Furthermore with alarm monitoring option the indicator has two intrinsically safe alarm outputs.
These outputs change their state, when the measured value exceeds his alarm limits. It’s possible to choose open-circuit or closed-circuit connection.
Additional the alarm limits appear graphically on a second bargraph. On one look you’re sure
that the measured value is in its limits.
2.2
Option: Internal zener barrier
The standard digital indicator D122 works exclusively in intrinsically safe 4..20 mA current circuits (EEx i). If the concerned measure current circuit is not intrinsically safe, an extra zener
barrier or an isolated interface and a long additional cable to the interface outside the hazardous area and back is needed.
In those cases the option integrated zener barrier is very practical, because the interface is
build in. A further advantage of an indicator with this option is that the intrinsical safety proof
is not required. The ignition protection is EEx m [ib] IIC T6 at ambient temperature of 50°C, E
Ex m [ib] IIC T4 at 65 °C respectively.
The terminal voltage in the measure circuit with internal zener barrier option is about 2 V.

5 Special software
Page 17
Option special software
The indicator D122.AS as well as the totalizer D122.ZS have a special software option. With this option it is possible to use this devices in any individual cases of measurement and indication.
Curve fitting
The curve fitting software indicates the measure current in a non-linear way. Consider the application of a filling-level meter for a sphere-tank. The measure current is linear to the filling-height of the
liquid. But the function between the filling-height and the volume is non-linear, as shown in the figure
below.
To get the correct quantity indication you require a list of points, which shows the connection between measure current and associated quantity inside of the tank. The curve fitting software of the
D122.XS interpolates the curve between these points on your choice in a linear or a square way.
The linear interpolation generates imaginary straight lines between the selected
points. A value on this line will be calculated on base of his distance to the previous selected point. This kind of interpolation requires 17 points to scale 4 up to 20
mA.
On the other hand the square interpolation needs a list of 33 points, but it approximates the original curve much better than the linear one, so the error between the original curve and the interpolated curve is much smaller.
To put in the list of selected point enter the (extended) scale menu. The device displays the measure
current and you have to enter the associated display value. See also flow diagram in Figure 13.
Squareroot-fitting
To program a squareroot-function, e.g., to display the flow through a aperture, a special squarerootfitting feature is available. For this option it is not necessary to enter a list of points, but just a startand a end-value (in previous example: associated flow by 4 and by 20mA measure current). The device calculates automatically the selected points for interpolation. Be prepared, this procedure will take
some time. See also flow diagram in Figure 13.
