2. GENERAL CHARACTERISTICS
• Multifunctional
Device is designed for recording, displaying current or averaged values and
presentation of technological parameter trends in graphic form.
• Large data storage capacity
The registered measurement results are recorded in the unit's memory. The
capacity of installed memory allows to store:
–over 500 000 measurements (2MB) for units equipped with RS-485 interface
–over 2 000 000 measurements (8MB) for units equipped with RS-485 interface
and USB Host port.
• Configurable measurement and control input
The unit has up to 8 channels (depending on version) of measurement signals and
one digital voltage input with programmable functions, e.g. control of the recording
process. Each signal can be freely configured and described. Depending on device
version all measured parameters must be available as current type signals
(0-20 mA or 4-20 mA standards) or resistance (Pt100, Pt500 or Pt1000 standards).
The internal analogue-digital converter has a 12 or 16 bit resolution (depending on
input type), which provides high measurement resolution results. Additionally,
individual alphanumeric description (text) of each of the recorded channels is
possible.
• Fast serial interface
The data logger is fitted with a galvanic isolation RS-485 interface, programmed
with ModBus RTU transmission protocol. This enables the connection of a number
of data recorders into the network, remote collecting of data from each unit and also
remote configuration. The application of the RS-485 interface instead of RS-232 is
due to the possibility of achieving high transmission speeds using transmission lines
of larger length than is possible with the RS-232 interface.
• Built-in USB Host interface (optional)
Optionally the device can be equipped with built-in USB Host interface, allowing for
data transfer to popular USB Flash Drives (PenDrives). This method allows for
significant simplification of unit application: it is no longer necessary to connect PC
and data logger via RS-485 interface.
Significant acceleration of data transfer is an additional advantage: data download
can be 10 times faster than using RS-485 interface.
WARNING! Device should work properly with any standard Flash Drives, but
manufacturer can not guarantee proper cooperation with non-standard devices, or
with devices developed after data logger release.

User manual - DATA RECORDER SRD-99 and cooperating software
• Wide range of power supply voltage and external sensor power supply
The built-in pulse power supply allows power to be supplied to the unit with
85...230...260V AC/DC voltage or 16...24...35 AC, 1 ...24...50 DC voltage
(depending on version). Data logger (version with current inputs only) is equipped
with voltage output for powering the sensor and converters: 24V DC ±5% / max.
200mA.
• Legible graphic display
The 128 x 64 points display with a backlight mounted on front of the unit is a big
advantage of the data recorder. It allows the display of trend graphs for each
channel separately. Different operation modes provide the possibility of selecting
and adjusting the method of data presentation depending on the user's
requirements. Data recording intervals are selected by the user from the menu
level. Additionally, it is possible to set the display to show one current value
measured for a selected channel.
• Easy configuration
There are 6 keys on the front of the data recorder that enable the configuration of
the unit. The menu assisted with full text descriptions makes the unit configuration
process quite easy. However, due to a significant number of configured parameters
it is advised to use the attached configuration software for PCs.

4. DEVICE INSTALLATION
The unit has been designed and manufactured in a way assuring a high level of user
safety and resistance to interference occurring in a typical industrial environment. In order to
take full advantage of these characteristics installation of the unit must be conducted correctly
and according to the local regulations.
- Read the basic safety requirements on page 4 prior to starting the installation.
- Ensure that the power supply network voltage corresponds to the nominal
voltage stated on the unit’s identification label.
- The load must correspond to the requirements listed in the technical data.
- All installation works must be conducted with a disconnected power supply.
- Protecting the power supply connections against unauthorized persons must be
taken into consideration.
4.1. UNPACKING
After removing the unit from the protective packaging, check for transportation damage.
Any transportation damage must be immediately reported to the carrier. Also, write down the
unit serial number located on the housing and report the damage to the manufacturer.
4.2. ASSEMBLY
- The unit is designed for mounting inside housings (control panel, switchboard)
inssuring appropriate protection against surges and interference. Metal housings
must be connected to ground in a way that complies with the governing
regulations.
- Disconnect the power supply prior to starting assembly.
- Check the connections are wired correctly prior to switching the unit on.
In order to install the unit, a 0,5 x 0,5 mm mounting hole (Fig. 4.1) must be
prepared. The thickness of the material of which the panel is made must not exceed
5mm. When preparing the mounting hole take the grooves for catches located on
both sides of the housing into consideration (Fig. 4.1). Place the unit in the
mounting hole inserting it from the front side of the panel, and then fix it using the
brackets (Fig. 4.3). The minimum distances between the center points of multiple
units - due to the thermal and mechanical conditions of operation - are 115 mm x
115 mm (Fig. 4.5).

4.3. CONNECTION METHOD
Caution
- Installation should be conducted by qualified personnel. During installation all
available safety requirements should be considered. The fitter is responsible for
executing the installation according to this manual, local safety and EMC
regulations.
- The unit is not equipped with an internal fuse or power supply circuit breaker.
Because of this an external time-delay cut-out fuse with a small nominal current
value must be used (recommended bipolar, max. 2A) and a power supply circuit-
breaker located near the unit. In the case of using a monopolar fuse it must be
mounted on the phase cable (L).
- The power supply network cable diameter must be selected in such a way that in
the case of a short circuit of the cable from the side of the unit the cable shall be
protected against destruction with an electrical installation fuse.
- Wiring must meet appropriate standards and local regulations and laws.
- In order to secure against accidental short circuit the connection cables must be
terminated with appropriate insulated cable tips.
- Tighten the clamping screws. The recommended tightening torque is 0.5 Nm.
Loose screws can cause fire or defective operation. Over tightening can lead to
damaging the connections inside the units and breaking the thread.
- The separable clamps should be inserted into appropriate connectors in the unit,
even if they are not used for any connections.
- U used termi als (marked as .c.) must ot be used for co ecti g a y
co ecti g cables (e.g. as bridges), because this ca cause damage to the
equipme t or electric shock.

- If the unit is equipped with housing, covers and sealing to, protecting against
water intrusion, pay special attention to their correct tightening or clamping. In the
case of any doubt consider using additional preventive measures (covers, roofing,
seals, etc.). Carelessly executed assembly can increase the risk of electric shock.
- After the installation is completed do not touch the unit’s connections when it is
switched on, because it carries the risk of electrical shock.
Due to possible sig ifica t i terfere ce i i dustrial i stallatio s appropriate measures
assuri g correct operatio of the u it must be applied. To avoid the u it of improper
i dicatio s keep recomme datio s listed below.
-Avoid running signal cables and transmission cables together with power supply cables
and cables controlling inductive loads (e.g. contactors). Such cables should cross at a
right angle.
-Contactor coils and inductive loads should be equipped with interference protection
systems, e.g. RC-type.
-Use of screened signal cables is recommended. Signal cable screens should be
connected to the earthing only at one of the ends of the screened cable.
-In the case of magnetically induced interference the use of twisted pair of signal cables is
recommended. Twisted pair (best if shielded) must be used with RS-485 serial
transmission connections.
-In the case of measurement or control signals are longer than 30m or go outside of the
building then additional safety circuits are required.
-In the case of interference from the power supply side the use of appropriate interference
filters is recommended. Bear in mind that the connection between the filter and the unit
should be as short as possible and the metal housing of the filter must be connected to
the earth with the largest possible surface. The cables connected to the filter output must
not be run with cables with interference (e.g. circuits controlling relays or contactors).
Connections of power supply voltage and measurement signals are executed using the
screw connections on the back of the unit’s housing.

The Pt100 / Pt500 / Pt1000 sensor can be connected to the device in typical 3-wire circuit
(Fig. 4.14 a) or 2-wire circuit (Fig. 4.14 b). Due to precision of measurement 3-wire circuit is
recommended.
If 2-wire circuit is used, the resistance of wires should be as small as possible, to
avoid of measurement errors. Measured value can be corrected (constant
correction) using „Bias” parameter from menu „I put setti gs”. Due to low
precision 2-wire connection is not recommended.

When 2-wires connection is used, the resistance of particular wires (Ra ÷ Rc) NEEDN'T
BE DIFFERENT (should be as small as possible) When 3-wires connection is used, the
resistance of particular wires (Ra ÷ Rc) MUST BE IDENTICAL to enable proper compensation
of it's resistance. The resistance of particular wire should ot be greater tha 20
Ω .

a) 3-wire circuit; b) 2-wire circuit;
The connection circuit should not be changed while unit is powered. Every change
of connection while the unit is powered causes measurement errors by several
seconds after change.
4.4. MAINTENANCE
The unit does not have any internal replaceable or adjustable components available to
the user. Pay attention to the ambient temperature in the room where the unit is operating.
Excessively high temperatures cause faster ageing of the internal components and shorten the
fault-free time of the unit's operation.
In cases where the unit gets dirty do not clean with solvents. For cleaning use warm water with
small amount of detergent or in the case of more significant contamination ethyl or isopropyl
alcohol.
Using any other agents can cause permanent damage to the housing.
Product marked with this symbol should not be placed in municipal waste. Please
check local regulations for disposal of electronic products.

. PRINCIPLE OF OPERATION
After turning the power supply on, the logo and basic unit data are showed on the
display, then the unit goes to the measurement mode.
.1. MEASUREMENT MODE
In the measurement mode the unit executes the measurement of values of signals
connected to measurement inputs, hereafter called measurement channels (the number of
available channels depends on the unit version). For each channel measurements are
conducted at the frequency of 8 times per second (I version and U version), 1 time per 2.5
seconds (RTD version) or 2 times per second (TC version). The results of the conducted
measurements are shown on the LCD display. The unit computes the measurement results
into indicated values proportionally (linear).
All available parameters of the unit’s operation can be configured in the main menu (see
DEVICE PROGRAMMING) or using the RS-485 interface and software installed on your PC.
Configuration of the device (via menu or RS-485 interface) do ot stops the data
recordi g process .
Results of measurements conducted for active (selected by the user) channels of the unit are
displayed in one of the available result presentation modes (see RESULT PRESENTATION
MODES).
.1.1.
Measurement ranges definition of current inputs
(
I version )
The nominal range of input current for each input is 0-20 mA or 4-20 mA and can be
extended to the maximum of 0-22 mA, independently to each measurement channel. The
range of measurement results corresponding to the nominal range of input current is defined
as user defined range. The range of measurement results corresponding to the range of input
current including the extensions is defined as allowable measurement range (Fig. 6.1). All
values presented as sliders are scaled due to user defined range. Graph is scaled due to
allowable measurement range.
* "Lower ext." parameter is only significant for an input current range of 4-20 mA.
Fig. 6.1. Definition of mea urement range (I version)
The range of displayed values, unit of measured value and position of the decimal point
(for presentation in numeric form) and name of channel are defined by the user.
