1 Operation instruction for Explosion protected device
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".
Use this manual 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 you should observe the respective nationally valid regulations and requirements.
General Instructions
The device 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 Fehler! Unbekannter Name für Dokument-Eigenschaft.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.
Danger of static charge!
Clean only with humid cloth!
Do not open when an explosive dust atmosphere is present!

D 122.Z 2 Totalizer with current input
2 Totalizer with current input D 122.Z
Page 4
2.1 Short description
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
.

3.3 Internal zener barrier option
Devices with type code D122.A.x.x.BM
The standard digital indicator D122 works exclusively in intrinsically safe 4..20 mA current circuits (Ex 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 Ex m [ib] IIC T6 at ambient temperature of 45°C, Ex m [ib] IIC T5 at
60 °C respectively.
The terminal voltage in the measure circuit with internal zener barrier option is about 2 V.

4.3 Configuration
It is easy to set the parameters and change the configuration of the totalizer. The inputs are logical grouped by a menu structure. The flow charts of these menus can be found at chapter 6.
Totalizers without the alarm monitoring option do not have the corresponding menu items.
)
Normal state
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
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)

;
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
=
E
M

S 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
=
1000 g g min
⋅
1 g
60 s
⋅
=
60 000 6 10

E
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“.
;
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.
