This instruction manual must be available at any time at the operation site of the RD400P.
Regional and national regulations respectively, have to be observed in addition to this instruction
manual if necessary.
In case of any obscurities or questions with regard to this manual or the instrument please contact
manufacturer.
Warning!
Supply voltage!
Contact with supply voltage carrying non-insulated parts may
cause an electric shock
with injury and death.
Measures:
• Note all applicable regulations for electrical installations (e.g. VDE 0100)!
• Carry out maintenance only in strain less state!
• All electric works are only allowed to be carried out by authorized qualified personnel.
Warning!
Inadmissible operating parameters!
Undercutting and exceeding
respectively of limit values may cause danger to persons
and material and may lead to functional and operational disturbances.
Measures:
• Make sure that the RD400P is only operated within the admissible limit values indicated on the
type label.
• Strict observance of the performance data of the RD400P in connection with the application.
• Do not exceed the admissible storage and transportation temperature.
Further safety instructions:
• Attention should also be paid to the applicable national regulations and safety instructions during
installation and operation.
• The RD400P is not allowed to be used in explosive areas.
Additional remarks:
• Do not overheat the instrument!
• Change of battery and SD-Card are only allowed to be carried out by authorized qualified personnel
and in strain less state
Attention!
Malfunctions at the RD400P!
Faulty installation and insufficient maintenance may lead to malfunctions of the RD400P
which may affect the measuring results and which may lead to misinterpretations.

Safety instructions
RD400P Rev1.0 Jul20 Page 7of 108
1.1 Installation
NOTE!
The plug of the power supply unit (charger) is used as a separator.
This separator must be clearly recognisable and easily accessible by the user. A
plug connector with a CEE7/7 system is necessary.
NOTE!
Only the supplied power supply may be used.
1.2 Lithium Ion Battery
Warning!
Battery!
The replacement of the battery must only be carried out by authorised and
skilled personnel, and when the device is de-energised.
Only the original battery of the manufacturer with built-in protection circuit
may be used
•Do not use any other power supply for charging the Li-Ion battery as the provided.
•Do not charge the battery under conditions that are not specified in the manual.
•Do not charge the battery in an environment with flammable substances. Never charge the
battery unattended.
•Transport
The contained lithium ion batteries are subject to the Dangerous Goods Legislation requirements. The user
can transport the batteries by road without further requirements.
When being transported by third parties (e.g.: air transport or forwarding agency), special requirements on
packaging and labelling must be observed. For preparation of the item being shipped, consulting an expert
for hazardous material is required.
Please also observe possibly more detailed national regulations.
Disposal
The datalogger, rechargeable batteries, accessories and packaging should be sorted for
environmental friendly recycling.
Do not dispose of power tools and batteries/rechargeable batteries into household waste!
Only for EC countries:
According to the European Guideline 2012/19/EU, power tools that are no longer
usable, and according to the European Guideline 2006/66/EC, defective or used
battery packs/batteries, must be collected separately and disposed of in an environmentally
correct manner.
Batteries no longer suitable for use can be directly returned at:

Application area
RD400P Rev1.0 Jul20 Page 8of 108
2 Application area
Our long-term hands-on experience in measurement and control technology was implemented in the
new RD400P.
From recording of the measured data, automatic sensor identification, indication on a big colour
screen, alerting, storage up to remote read-out via web server, all that is possible with RD400P. By
means of the EDC-Soft, software alarms can be sent via SMS or e-mail.
On the big 3.5' colour screen with touch panel all information is available at a glance.
The operation is very easy. All measured values, measured curves and threshold exceeding’s are
indicated. The progression of the curve, since the beginning of the measurement, can be viewed by
an easy slide of the finger.
The huge difference to ordinary paperless chart recorders reveals in the easy initiation as well as in
the evaluation of the measured data. All sensors are identified directly and powered by RD400P.
Everything is matched and tuned.

Versatile:
Up to 4 sensors (consumption, dew
point, pressure, current, KTY, PT 100,
PT 1000) are identified automatically by
RD400P. Optional analogue sensors
(0/4 - 20 mA, 0 - 1/10/30 V, pulse) can
be configured easily and quickly.
Digital sensors can be connected via
RS 485, Modbus RTU and SDI.
Flexible:
Network-compatible and
worldwide remote data
transmission via Ethernet,
integrated web server.
Alarm relay / fault indication:
Up to 4 threshold values can be configured freely. Collective alarms are possible.
Remark:
Alarm relays are available with RD400P, not accessible at RD400P.

Intended use
RD400P Rev1.0 Jul20 Page 9of 108
3 Intended use
The RD400P data logger serves for the stationary measured data acquisition and storage of analogue
and digital input signals.
The RD400P data logger is exclusively designed and constructed for the proper application purpose
that is described herein and must only be used correspondingly.
A check in order to ascertain whether or not the device is suitable for the chosen employment must be
carried out by the user. It must be ensured that the medium is compatible with the components which
come into contact with it. The technical data listed in the data sheet are binding.
Improper handling or operation outside the technical specifications is impermissible. Claims of any kind
on the basis of improper use are excluded.

Connect the RD400P with a PC
RD400P Rev1.0 Jul20 Page 18 of 108
8 Connect the RD400P with a PC
Important:
The IP addresses of PC and RD400P must be statically assigned (DHCP off) and have to be
in the same network.
If the IP-address of the RD400P has changed, you have to reboot!
Remark:
IP-address of the RD400P:See chapter, 9.3.3.3 Network-Settings
Reboot the RD400P:See chapter,9.3.3.6.6 Factory-Reset
The RD400P can be connected with the PC by a crossover cable, which has a RJ45 plug on each
side, or an Ethernet cable with a crossover adapter.
Crossover-Cable with RJ45-plug
After connecting the RD400P via a suitable cable to the PC, you can make graphical and tabular data
evaluations with the EDC Basic software.

Operation RD400P / Main menu (Home)
RD400P Rev1.0 Jul20 Page 19 of 108
9 Operation RD400P
The operation is largely self-explanatory and menu-driven via the touch panel.
The selection of the respective menu items occur via short "tapping" with the finger or a soft round pen.
Attention: Please use no pens or other objects with sharp edges!
The foil can be damaged!
After sensors are connected, they also have to be configured.
Inputs or changes can be made with all white deposit fields.
The measured values can be represented as a curve or values.
Words in green font refer mainly to the pictures in the section of the chapter, but also on important menu
paths or menu items that are related to be in green font.
The menu navigation is generally in a green font!
The table of contents and chapter references in blue font contain links to the respective chapter title.
9.1 Switching on / off of the RD400P
To switch on / off the RD400P you have to press ( >= 3sec) the on / off knob.
A short press of the on / off knob during operation opens a popup with indication of the remaining
operation time.
9.2 Main menu (Home)
From the main menu, you can reach every available item.
9.2.1 Initialization
Please see chapter 9 then select appropriate configurations and set!
After switching on the RD(DS)400 all
channels are initialized and the main menu
will appear.
Attention:
For the first initiation, there may be no
channels preset!
