1 Safety instructions
1.1 General
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 DS 500 is only operated within the admissible limit values indicated on the
type label.
•Strict observance of the performance data of the DS 500 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 DS 500 is not allowed to be used in explosive areas.
Additional remarks:
•Do not overheat the instrument!
•Change of battery or SD-Card are only allowed to be carried out by authorized qualified personnel.
and in strainless state!
Attention!
Malfunctions at the DS 500!
Faulty installation and insufficient maintenance may lead to malfunctions of the DS 500
which may affect the measuring results and which may lead to misinterpretations.
R
Please check whether this manual corresponds with the device type.
Please attend to all notes indicated in this instruction manual. It contains essential information
which has to be followed during installation, operation and maintenance. Therefore, this
instruction manual has to be read categorically by the technician as well as by the responsible
user/qualified personnel before installation, initiation and maintenance.
This instruction manual has to be available at any time at the operation site of the DS 500.
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
CS Instruments GmbH.

Safety instructions
DS 500 V1.55 Page 8 of 124
1.2 Installation
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.
Danger!
Missing earth connection!
When the earth connection (protective earth) is missing, there is the
risk in the event of malfunction, that contactable, conductive
components may carry supply voltage. Touching of such parts leads
to an electric shock with injuries and death.
It is imperative to connect the plant to earth or to connect the
protective conductor according to the regulations.
Do not use plug adapters at the power plug.
Have the power plug replaced by qualified skilled persons, if
required.

Safety instructions
DS 500 V1.55 Page 9 of 124
The plug of the power supply cord is used as a separator. This separator must be clearly recognizable
and easily accessible by the user. A plug connector with a CEE7/7 system is necessary.
All the electrical lines carrying supply voltage or another voltage that is dangerous in the case of con-
tact (power supply cord, alarm and indicator relays), must additionally be equipped with double or
reinforced insulation (EN 61010-1). This can be ensured by using plastic-sheathed cables, a second
insulation (e.g. flexible insulating tubing), or correspondingly suitable lines with reinforced insulation.
The connecting cables can be equipped, for example, with flexible insulating tubing.
The additional flexible insulating tubing must withstand the electrical and mechanical stresses which
can occur during the intended use (see EN 61010-1, Clause 6.7.2.2.1).
DANGER!
Supply voltage!
When wiring the connecting lead, it must be ensured that the double or
reinforced insulation be-tween the electric circuits that are dangerous in the
case of contact and the contactable secondary circuit remains maintained.
NOTE!
The additional insulation must be suitable for a test voltage of 1500 V
alternating current.
The thickness of the insulation must be at least 0.016 inch.
E.g. flexible insulating tubing, type BIS 85 (Bierther GmbH).
The additional insulation of the connecting leads (mains connection, alarm and indicator relays) can
be implemented as follows:
3 2 1
(1) - Terminals (connectors)
(2) –Flexible insulating tubing for the connecting leads
(3) –Connecting cable

Application area
DS 500 V1.55 Page 10 of 124
2 Application area
Our long-term hands-on experience in measurement and control technology was implemented in the
new DS 500.
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 DS 500. By
means of the CS-Soft, software alarms can be sent via SMS or e-mail.
On the big 7' 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.
Daily, weekly and monthly reports, with costs in € and counter reading in m
3
, for each consumption
sensor are completing the sophisticated system concept.
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 DS 500.
Everything is matched and tuned.
Versatile:
Up to 12 sensors, incl. all CS sensors
(consumption, dew point, pressure, current,
KTY, PT 100, PT 1000) are identified auto-
matically by DS 500. 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 32 threshold
values can be
configured freely and
allocated to 4 different
alarm relay. Collective
alarms are possible.

Intended use
DS 500 V1.55 Page 11 of 124
3 Intended use
The DS 500 data logger serves for the stationary measured data acquisition and storage of analogue
and digital input signals.
The DS 500 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.

By/With consumption sensors and dew point sensors from CS Instruments there is the possibility to provide
values as analogue current signal 4 –20 mA for further working process.
The measurement/reading of the current signal for an external PLC/ZLT or external third-party display is
explained in the connection diagrams.

DS500 with ext. 4 -20mA routing
It´s possible to connect the FA 300/FA 425 alternatively as 4 –20 mA
analogue sensor in 2-wire technology.
To route the current signal of 4 - 20 mA to an external display, PLC or
ZLT, please remove the bridge from Pin 4 (Analog IN) to support Pin
9 (ext. display) and then connect the external display according
schematic.
