3 GENERAL PRODUCT OVERVIEW
3.1 Purpose
DL2 is a multi-channel microprocessor-based measuring device with electronically
recorded measurement results. The device is intended to measure process signals in
industrial applications and may be used to measure temperature and other physical values
processed into a standard current loop signal 0/4-20mA, e.g. humidity, pressure, flow,
level and chemical composition, etc. The device is perfectly suited for slow rate variable
runs with changes at a few seconds intervals. Process values recording and flexible I/O
configuration, makes the DL2 data logger suitable for monitoring parameters in warehouse
settings or in process lines, where multipoint measurements are required, especially in: the
glass making industry, food processing, refineries, as well as chemical and pharmaceutical
industries. The device has math channels that enable selected mathematical operations
on the measured values, according to the formulas entered by the user. The user
configurable display and browse functions makes the device suitable for use as a paperless electronic logger. The device may be connected to a PC or plant control system via
Ethernet or RS-485 communication ports.
Each device is provided with a basic module and can be extended with additional I/O
modules. Details are provided in section DL2 AVAILABLE I/O MODULES.

6.3.3 Connection of RS-485 data transmission line
Fig. 6.22 Wiring diagram for RS-485.
Notes:
The device RS-485 receiver/driver allows connection of up to 32 devices.
An RS485-MODBUS configuration must have one trunk cable, along which devices
are connected, directly (daisy chaining) or by short derivation cables.
The maximum bus length depends on the baud rate, the cable (gauge, capacitance or
characteristic impedance), the number of loads on the daisy chain. For a 9600 Baud Rate
and 0.125 mm2 (AWG26) or wider gauge, the maximum length is 1200 m. The derivations
must be short, never more than 20 m.
To minimize the reflections from the end of the RS-485 cable it is required to place a
line termination near each of the 2 ends of the bus. The device has an internal termination
system, activated by DIP switch on the left side of the terminal block. The correct operation
of the terminator requires setting both switches in the same position.
The “common” wire should be used for all RS-485 ports. For DL2 device as a common
signal the power supply “-“ (terminal no. 14) or functional ground (terminal no. 15) have to
be used.
6.3.4 Ethernet port
Ethernet (100Base-T) port is located in the rear panel of the device. Outputs
connections are compliant with EIA/TIA-568A/B. A wire of 8 twisted conductors may be
connected to this port ended with RJ-45 plug.

[1]: It allows to switch the measurement input on or off.
[2]: It enables adjustment (offset) to the measured millivolt signal value.
[3]: The compensation method of thermocouple reference junction (cold junction
compensation). Compensation can be provided by another measurement channel. In
particular, a fixed value can be selected for compensation. However, this type of
measurement is likely to be incorrect. As a rule, Pt100 sensor connected to the last
measurement channel is used as a compensation sensor. During the programming of
the compensation settings, attention to use the same temperature units °C or °F for
both measured and compensation channels should be paid.
[1]: RTD sensors can be connected in a three-wire or four-wire configuration with
automatic cables resistance compensation or a two-wire configuration without
compensation.
[2]: Resistance correction allows the cable resistance values to be entered manually in
the two-wire configuration. If the sensor is connected in a three-wire or four-wire
configuration (automatic compensation), the resistance correction can be used to
compensate the sensor error by “offsetting” the characteristics by adding the positive
or negative resistance value.

12.4 Channels settings
The channel number is selected using the drop-down list, located in the upper left
corner of the screen. The description of the channel can be edited by clicking on the text in
Tag field. Then, the screen keyboard will pop up.
For commissioning channels settings there are six settings tabs available: Inputs,
General, Alarm 1, Alarm 2, Σ1, Σ2. It is possible to copy settings between channels (more
in section Copying channel settings).
Fig. 12.4 An example view of the ‘Channel’ settings window (math channel).
12.4.1 Inputs
Depending on the channel selection, suitable settings are available:
Channel Type: Disabled (Disabled, Measurement, Computed, Demo(TEST))
Input: A (A, B, M)
Input number: 1 (1, 2, 3, 4, 5, 6)
Characteristic: Linear (Linear, depending on the module type)
[2]
[3]
[4]
[1]
[1]: The “Channel Type” possible configuration: Disabled – the channel is off and not
displayed, Measurement – measured process value from input module should be
assigned to the channel, Computed – the mathematical formula used for calculations
must be entered – more details are in section math channels, Demo(TEST) – a sin (t)
function value is virtually generated, enabling e.g. the communication test without the
input signals applied.
[2]: A drop down list allows to select a suitable measurement module slot. After the
selection, on the right side of the list, the module tag is displayed enabling its
identification.
[3]: The drop down list allows to select an input / output number of the measurement card
to which a selected channel is to be assigned.
62

[4]: The characteristic is typically set to "Linear". Also available are other setting options
(for example User characteristic), depending on the module type. For example, for
the RTD module there are characteristics of the individual sensor types available.
12.4.2 General
Fig. 12.5 An example view of the ‘Channel’ settings window –‘General’ tab.
[1]: The unit is provided for information purposes only. User can put in any text string
which does not affect the calculated or measured results displayed by the device.
[2]: The Time base is crucial only for flow measurements and totalizers calculation. In
spite of Unit set above, it determines calculations for totalizes and flows according to
/s (per second), /m (per minute) or /h (per hour) setting.
[3]: The resolution defines the number of decimal places in the displayed result. It is
unreasonable to set too high resolution for the measurement, because accuracy will
not be improved (e.g. Pt100 sensor measurement set to three places after the
decimal point will not provide for measurement accuracy of up to 0.001°C). However,
if a filter is activated with sufficiently high time constant and if the resolution is
reasonably increased, the changes can be identified more clearly.
[4]: The filter function “smoothes out” sudden surges in the measured values or
eliminates signal noise. If the filter time constant is too high, the measurement value
fluctuations can be falsified by "smoothing out" the ascending and descending
slopes, or by eliminating short pulses. The filter time constant should be customized
to the maximum speed of changes in the measured process.
[5]: It enables on / off the archiving of the results to a file in internal archive memory.
63
DL2
[6]: The failure value is the constant value which is displayed instead of the measurement
result if the input signal fails or calculation result is out of range.

Log event: Disabled (Disabled, Enabled)
Change the frequency of archiving: Disabled (Disabled, Enabled)
[1]: The threshold can be set to High (active above a specific level) or Low (active below
a specific level) operation mode.
[2]: Setting of the Type: Alarm (or so called latched mode) allows to indicate the alarm
notification with confirmation procedure. Type: Control (or so called non-latched
mode) allows to indicate the threshold status or use relays outputs to set a simple
on/off control (e.g. heating or cooling).
[3]: The alarm threshold level value is entered in the measured value units assigned.
[4]: The hysteresis value is the difference between the threshold value exceedance and
return to normal. The threshold hysteresis value is entered in units of the measured
value assigned to a specific measurement channel. For example, for a threshold set
to High, 48 °C threshold level and 0.5 °C hysteresis means that the threshold will be exceeded above 48 °C, and will return to normal below 47.5 °C (48-0.5). For a
threshold set to Low, -15 °C threshold level and 0.2°C hysteresis means the
threshold will be exceeded below -15 °C, and will return to normal above -14.8 °C
( -(15-0.2)).
[5]: Each alarm/control threshold can have a colour assigned. If the threshold is
exceeded, the measurement result is displayed in a different colour: Green, Yellow or
Red (assigned to this alarm).
[6]: The drop down list enables selecting a suitable module and output to which the used
output relay is connected.
[7]: Enabling the option switches on the archiving of the thresholds exceeded to the
event file.
[8]: The recording of measurement results can be controlled by alarm/control thresholds.
Two different recording speeds can be set. The exceeded threshold can switch from
MAIN ARCHIVE interval I to MAIN ARCHIWE interval II.

the totaliser at any moment, Daily – the totaliser is erased every 24 hours, Weekly the totaliser is erased after the elapse of a week, Monthly - the totaliser is erased
after the elapse of a month.
[2]: The unit is provided for reference purposes only. User can enter any unit which does
not affect the results displayed by the device.
[3]: The multiplier allows multiplication of the measurement results by one of the three
values selected from the list. For example, if a flow meter is connected to the device
measuring the flow in m3/s and the user wants the result to be displayed in dm3/s, the
multiplier should be set to 1000. In a reverse situation, when the measurement would
be made in dm3/s and the user would like the values counted by the totaliser to be
displayed in m3/s, the value of the multiplier should be set to 0.001.

The device performs calculations according to the order of operations
(operations in brackets, exponentiation / extraction of a root, division /
multiplication, addition / subtraction).
14 ADDITIONAL FUNCTIONS
14.1 Additional channel functions
14.1.1 Math channels
In order to set the calculation channel, choose from the menu bar the button and
then the channels icon . In the input tab, set the channel type: Computed and enter
the formula which the value will be calculated.
The device allows to perform selected mathematical operations: addition, subtraction,
division, multiplication, raising to the power of 2 and 3 and the square root. The entered
formula can contain up to 200 characters.
The value of another channel may be used in calculation. In this case, the channel
number should be preceded by # sign.
For example:
formula #1+#2adds the values of the first and second channels.
In calculation of square root, the value is calculated of only first character after the
√ mark. If the square root has to be calculated from the value of several channels,
calculated value should be placed in brackets.
For example:
formula √123 calculates the square root of 123,
formula √#1 calculates the square root of the value of channel 1,
formula √#1+#2 calculates the square root of channel 1 and to the
result adds the value of channel 2,
formula √(#1+#2) calculates the square root of the sum of values
channels 1 and 2.
Similarly, in the case of exponentiation (the possibility of choosing the second and the
third power), the value is calculated of only the first character entered before the 2 or 3
mark. If the value from several channels is raised to power 2 or 3, the calculated value
should be put in brackets.
For example:
formula 1232 raises the value of 123 to power 2,
formula #12 raises the value of channel 1 to the power of 2,
formula #1+#22 raises the value of channel 2 to the power of 2 and to
the result adds the value of channel 1,
formula (#1+#2)2 raises to the power of 2 the value from the sum of
values of channels 1 and 2.
72
DL2

Math channels have the same functions that allow analysis as measurement channels:
they can be displayed in the Result Tables window, in the Trends window and in a single
result window. It is possible to set alarms (Alarms) and archive their values (Archive).
14.1.2 User characteristics
User characteristics are given in the form of a pair of points: the value of the measured
resistance, current, voltage, etc. (x value) and the value displayed in the corresponding
units (y value). The user has the ability to add (Add point), delete (Delete point), and edit
(Edit value) points of the feature, with a minimum of 2 points and a maximum of 50. User
has the ability to add up to 10 characteristics.
To add a new characteristic, in the Channel settings window, the user must select
from the drop-down list the characteristics: User, then select one of the ten available
positions and select View button. Changing the characteristic tag after clicking the current
one in the Tag field.
New points can be added in any order, because they are automatically recognized and
sorted relative to the measured value x. To delete a point, select it by clicking and then
select Delete point button. You can edit points in the same way, using Edit Point button.
