Intended use
The insulation fault locators ISOSCAN® EDS440 and EDS44 are used to locate insulation
faults in unearthed DC, AC and three-phase power supply systems (IT systems).
Depending on the locating current injector, AC and three-phase systems can be
monitored within the range from AC 42 to 000 V; DC systems, within the range from
DC 24 to 500 V.
An AC residual current can be indicated in these ranges:
•EDS440: 42… 000 Hz, 0. …20 A
•EDS44 : 42…60 Hz, 0. …2 A
An EDS system (insulation fault location system) consists of an EDS44x insulation
fault locator and a locating current injector. EDS44… insulation fault locators detect
locating current signals generated by the locating current injector via measuring current
transformers and evaluate them accordingly.
Intended use also implies
•the observation of all information in the operating manual and
•compliance with test intervals.
In order to meet the requirements of the applicable standards, customised parameter
settings must be made on the equipment in order to adapt it to local equipment and
operating conditions. Please heed the limits of the range of application indicated in the
technical data.
Do not make any unauthorised changes to the device. Only use spare parts and optional
accessories sold or recommended by the manufacturer.
The messages of the device must be perceptible even if it is installed in a control cabinet.
The devices is not designed for use in residential areas and may not provide sufficient
protection for radio reception there.
Any other use than that described in this manual is regarded as improper.
Areas of application
•Insulation fault location in AC, 3(N)AC and DC IT systems
•Main circuits and control circuits in industrial plants and ships
•Diode-decoupled DC IT systems in power plants
•Systems for medical locations
Standards
The standard for unearthed power supplies (IT systems)
DIN VDE 0100-410 (VDE 0100- 410):2018-10 (IEC 60364-4-41:2005, modified + A1:2017,
modified)
requires that the first insulation fault is to be eliminated with the shortest practicable
delay. EDS systems enable fast localisation of this insulation fault.

ISOSCAN® EDS440 and EDS44
Operating principle of the EDS system
When an insulation monitoring device detects an insulation fault,
it starts the insulation fault location.
In the event of a first insulation fault, an undefined residual
current flows in IT systems, which is primarily defined by the
system leakage capacitances and the value of the insulation fault.
The basic idea of insulation fault location is therefore to generate a
defined locating current IL that flows through the insulation fault.
The locating current is driven by the system voltage and can be
located in the faulty outgoing circuit using the measuring current
transformer.
The locating current is generated by the locating current injector.
It is limited in amplitude and time. The amplitude depends on the
size of the existing insulation fault and the system voltage. It is
limited depending on the settings.
The locating current flows from the locating current injector via
the live lines to the insulation fault location taking the shortest
route. From there, it flows through the insulation fault and the
earth conductor back to the locating current injector. This locating
current pulse is detected by the measuring current transformers
on the insulation fault path and signalled by the connected
insulation fault locator.
System variants
The devices ISOSCAN® EDS440 and EDS44 differ depending on their response sensitivity. EDS440 is suitable for main circuits. EDS44
can be used in control circuits and in circuits in medical locations.
