4 KEY INFORMATION ABOUT THE DEVICE
4.1 Intended use
DL7s are versions of a multi-channel microprocessor-based measuring device with
electronically recorded measurement results. The recorder is intended to measure process
signals in industrial settings and may be used to measure temperature values and other
physical quantities processed into a standard current signal 0/4-20mA, and in particular,
humidity, pressure, flow, level and chemical composition, etc. With the special structure of
the processing route applied, this recorder is perfectly suited for slow variable runs with
changes taking place at a few seconds intervals. With results recording function and
possibility to expand the device, this instrument is appropriate for use in monitoring
parameters in warehouse settings, process lines where multipoint measurements are
necessary, especially in the glass making industry, food processing, refineries, as well as
chemical and pharmaceutical industries. The device has math channels that enable the
execution of selected mathematical operations based on the values measured in the
measurement channels, according to the formulas entered by the user. The volume of data
saved as well as process display and browse functions makes the device suitable for use as
a paper-less electronic recorder.
Each device is provided with a basic module which, depending on the metrological
needs, can be appended with additional modules. Details of the individual modules are
provided in Sec. DL7 MODULES.
The device is intended to be supplied with 24V current: Detailed information concerning
the power supply is given in consecutive parts of the document Power connection
4.2 Basic functions
Measurement of the process values
Depending on the needs, the device may be provided with 3 to 42
measurement inputs/outputs. The product enables setting up to 100 freely programmable
channels. For each of them the current, the maximum and the minimum values of the
measurements are displayed.
Flow measurement
Each measurement input (incl. binary inputs) and each calculated value have two
independent totalizers assigned. Totalizers can measure slow variable flows, etc. Totalizers
for pulse inputs can provide precise pulse aggregation.
Control and alarm indicators
The bi-state output module activates the alarm controls if the value of the measurement
results are exceeded or simple bi-state control of the on-off type.
Calculation of selected values
Within the math channels, selected mathematical operations are available: addition,
subtraction, division, multiplication, raising to the power of 2 and 3, and square root. The
formula entered in the calculation channel can contain up to 200 characters.

DL7, DL7L
12
Results recording
Measurement and calculation results as well as totalizer readings can be recorded in
the recorder’s internal memory with the capacity of 2 GB. Data are saved as text files and
protected with encoded checksum. Apart from the measured values, the recorder also
saves events (power loss, resetting, exceeded threshold values, etc.) and authorised
operations.
Displaying the results
Measurement results can be displayed on the recorder screen or moved to a PC. There
is an LCD 7" touch screen graphical display on the face plate. Depending on the
configuration, the measurement and calculation results are displayed as digits or graphs.
The results can be also displayed collectively as tables or trend charts. Measurement
screens can be browsed sequentially or set to a selected channel.
Communication with a computer system
The recorder can be connected to a master computer system by means of:
a built-in RS-485 serial port; Modbus RTU protocol,
Ethernet port; available Modbus TCP protocol.
Supplementary software (optional)
Additional, DL7 - dedicated software enables device configuration through the use of
the computer. The software enables intuitive use and has an interface which is very similar
to the interface of the device. The software can be installed on the computers with the MS
Win operating system.
4.3 Device Versions
DL7 is a data recorder created with a view to enabling the best possible adaptation of
the device to the individual needs of the customer. Each device is composed of the base
module to which depending on the metrological needs additional, carefully selected, input
and output modules can be attached. Depending on the needs, the device may have
attached up to seven additional modules. Each of them is optionally provided with 3 or 6
measurement channels.
The device is available in a panel mount version (DL7) and free-standing (DL7L).
