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.

Totalizer with current input D 122.Z
2.1
Short description
Page 3
The 5-digit totalizer D122.Z operates in hazardous area and indicates the sum of measured values
of a 4 up to 20 mA current circuit. The device gets its energy from the measure circuit, therefore an
extra power supply or batteries are unnecessary. The totalizer measures the current, adds the previous values, scales the sum and displays the sum finally on the LCD.
The present measured signal is also be displayed on a 41 segment bargraph. It's
possible to scale the bargraph separately to the digital value. The totalizer D122 is
available in several housings.
The totalizer has 2 intrinsically safe alarm outputs as an option (D122.Z.x.2).
These outputs change their state, if the measured value exceeds his alarm limits.
It’s possible to choose open-circuit or closed-circuit connection.
It is possible to refer the alarm monitoring to the sum or to the present measured
value. In the last case the limits are displayed on a second bargraph. On one look
you’re sure that the measured value is in its limits.
Alternative to the option of two digital outputs for external limit monitoring, a control
input and a digital output are implemented to the totalizer D122.Z.x.3. An active
intrinsically safe signal (Low < 2V, High > 5V) on the control input sends a reset
command to the totalizer.
The digital output port can be configured by software in two different modes: As a
setpoint-reached message when the totalizer sum reaches its limit and as a pulse
output for the current flow signal. In this case, the D122 measures the present
flow rate and converts it to a digital signal.
The resolution of the digital signal is directly coupled with the scale configuration of
the totalizer: each increment of the least significant digit sends a pulse. The pulse
width is about 7 ms, by a maximum output frequency of 68 Hz.
The option curve and square root fitting offers a reproduction of an arbitrary monotone function of measured current and displayed value. A square root fitting function especial for measuring a flow through an aperture is implemented.

Normal state
Totalizers without the alarm monitoring option do not have the
corresponding menu items.
The Input-views in the flow diagrams have additional boxes
in their background, because the Input-views may be changed
by pressing any of the buttons.
The procedure, to enter a value, is shown in the flow diagram ‘Edit
menu’, see Figure 13.
After connecting, the totalizer D122 starts to initialise its configuration. The configuration data is stored in an internal EEPROM due
to the previous run. By the first start, the D122.Z totalizer initialises the default configuration.
Directly past starting sequence the totalizer begins to operate.
This state is called the ‘normal state’ of the D122 and the totalizer
is also ready for inputs.
(See also flow diagram in Figure 7)
Present-value control
Pressing and holding the up-button (present value control button) the display shows the present measured value.
(See also flow diagram in Figure 7)

Parameter input illustration
Prescale factor determination (I-fac)
The totalizer D122.Z adds the measured values to a sum and displays it. The measured value always
refers to second, so it is possible to sum short count events. Recording for a long time the sum gets
considerable bigger as the dimension of the present value.
To adjust the summation to each application, a prescale factor (I-fac) divides the sum to the desired
range. Using the prescale factor it is possible to adjustthe dimension of the instantaneous value to
the desired dimension of the sum. The prescale factor V is defined by
V = desired dimension of sum / dimension of the measured value
or
V=
ES
EM ⋅ [s]
Example: An measuring transductor has an output-signal with the dimension g/min. The sum should
have the dimension kg. The right prescale factor is
V=
kg
1000g
=
= 60000 = 6 ⋅ 104 = 6 E 4
g
1g
⋅ [s]
⋅ [s]
min
60s
According to this example the prescale factor V changes to 1000 (1E3) for a transductor signal with the dimension g/s, respectively 3600 000 (36E5) for a transductor signal with the dimension g/h.
The format of the prescale factor V is the exponent notation, i.e.
the figures in front of the zeros of V lie by the exponent notation
in front of the „E“ and the quantity of the zeros lie behind the „E“.
Note !
Creep suppression (StArt)
In some cases, it will be necessary to ignore a transductor signal
above 4 mA. This threshold level
is named creep suppression
value. The figure on the right
hand shows its function.

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 11.
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 11.
