Part of the device documentation in addition to this manual is the enclosed "Safety instructions for Bender products".
2.2 Work activities on electrical installations.
Only qualified personnel are permitted to carry out the work necessary
to install, commission and run a device or system.
Danger of electrocution due to electric shock!
Touching live parts of the system carries the risk of:
• A life threatening electric shock
DANGER
If the device is used outside the Federal Republic of Germany, the applicable local standards and regulations must be complied with. The European standard EN 50110 can be
used as a guide.
2.3 Device-specific safety instructions
WARNING
CAUTION
• Damage to the electrical installation
• Destruction of the device
Before installing and connecting the device, make sure that the
installation has been de-energised. Observe the rules for working on
electrical installations.
Make sure that the basic settings meet the requirements of the IT system.
Persons without the required expertise, in particular children, must not
have access to or contact with the ISOMETER®.
Make sure that the operating voltage is correct!
Prior to insulation and voltage tests, the ISOMETER® must be disconnected
from the IT system for the duration of the test. In order to check that the device has been correctly connected, a functional test must be carried out before starting the system.
Safety instructions
In the event of an alarm message of the ISOMETER®, the insulation fault
should be eliminated as quickly as possible.
If the ISOMETER® is installed inside a control cabinet, the insulation fault
message must be audible and/or visible to attract attention.
When using ISOMETER®s in IT systems, make sure that only ONE active
ISOMETER® is connected in each galvanically interconnected system. If IT
systems are interconnected via coupling switches, make sure that ISOMETER®s not currently used are disconnected from the IT system and deactivated. IT systems coupled via diodes or capacitances may also influence
the insulation monitoring process so that a central control of the different
ISOMETER®s is required.
Prevent measurement errors!
When a monitored IT system contains galvanically coupled DC circuits, an
insulation fault can only be detected correctly if the rectifier valves (e.g.
rectifier diode, thyristors, IGBTs, frequency inverters, …) carry a minimum
current of > 10 mA.
Unspecified frequency range
When connecting to an IT system with frequency components below the
specified frequency range, the response times and response values may
differ from the indicated technical data. However, depending on the application and the selected measurement profile, continuous insulation
monitoring is also possible in this frequency range.
There is no influence on the insulation monitoring for IT systems with frequency components above the specified frequency range, e.g. within the
range of typical switching frequencies of frequency inverters (2…20 kHz).

3.2 Product description
3.2.1 General product description
The ISOMETER® is an insulation monitoring device for IT systems in accordance with
IEC 61557-8.
It is universally applicable in AC, 3(N)AC, AC/DC and DC systems. AC systems may include
extensive DC-supplied loads (such as rectifiers, inverters, variable-speed drives).
3.2.2 Special ISOMETER® characteristics
The ISOMETER® iso685–D–P belongs to the iso685 device family and features an integrated display. This manual applies in full to this ISOMETER®.
The ISOMETER® iso685–S–P is the sensor variant from the iso685 device family. The only
difference between this variant and the ISOMETER® isoHR685-D-B is that it does not have
a display. The ISOMETER® iso685–S–P must be used in combination with a front panel
through which it is operated. The operation of the front panel is equal to the operation of
the ISOMETER® with an integrated display, which is described in this manual.
Only the sensor variant (i.e. ISOMETER® iso685–S–P) can be connected to
the front panel. Connection to the display variant (i.e ISOMETER® iso685–
D–P) is not possible.
11
Hereafter, the ISOMETER®s with integrated display are described. This description is similar to the combination of ISOMETER® sensor variants and the front panel FP200. The
devices to which this manual applies will be referred to as ISOMETER®s hereafter.

FunctionFunction
3.3 Function description
The insulation monitoring device continuously monitors the entire insulation resistance
of an IT system during operation and triggers an alarm when the value falls below a preset response value. To obtain a measurement the device has to be connected between
the IT system (unearthed system) and the protective earth conductor (PE). A measuring
current in the A range is superimposed onto the system which is recorded and evaluated by a microprocessor-controlled measuring circuit. The measuring time is dependent
on the selected measurement profiles, the system leakage capacitance, the insulation resistance and possible system-related disturbances.
The response values and other parameters are set using a commissioning wizard as well
as via different setup menus using the device buttons and a high-resolution graphical LC
display. The selected settings are stored in a permanent fail-safe memory. Different languages can be selected for the setup menus as well as the messages indicated on the display. The device utilises a clock for storing fault messages and events in a history memory
with time and date stamp. The settings can be password protected to prevent unauthorised changes.
To ensure proper functioning of connection monitoring, the device requires the setting
of the system type 3AC, AC or DC and the
L2, L3/-.
required use of the appropriate terminals
L1/+,
The insulation monitoring device iso685–x–P is able to measure the insulation resistance
reliably and precisely in all common IT systems (unearthed systems). Due to various applications, system types, operating conditions, application of variable-speed drives, high
system leakage capacitances etc., the measurement technique must be able to meet varying requirements in order to ensure an optimised response time and relative uncertainty. Therefore different measuring profiles can be selected with which the device can
optimally adjusted.
If the preset response value falls below the value of Alarm 1 and/or Alarm 2, the associated alarm relays switch, the LEDs ALARM 1 or ALARM 2 light and the measured value is
shown on the LC display (in case of insulation faults in DC systems, a trend graph for the
faulty conductor L+/L- is displayed). If the fault memory is activated, the fault message
will be stored. Pressing the RESET button resets the insulation fault message, provided
that the current insulation resistance displayed at the time of resetting is at least 25 %
above the actual response value. As additional Information, the quality of the measuring
signal and the time required to update the measured value are shown on the display. A
poor signal quality (1-2 bars) may be an indication that the wrong measurement profile
has been selected.
The ISOMETER® has an internal system isolating switch, which makes it possible to operate several ISOMETER®s in coupled IT systems. For this purpose, the ISOMETER®s are connected via an Ethernet bus. The integrated ISOnet function ensures that only one
ISOMETER® is actively measuring at a time, while the other devices are completely isolated from the system and waiting in standby mode for measuring permission.

3.4 Insulation fault location
An additional function of the ISOMETER® in combination with the EDS is the selective insulation fault location. Therefore, the ISOMETER® generates a periodic locating current after the values has fallen below the set response value R
(LED ALARM 2). Thereby, the
an2
system conductors are alternately connected to earth via a defined resistance. The resulting locating current depends on the size of the existing insulation fault and the system
voltage. It is limited by the ISOMETER® depending on the settings. The insulation fault is
selectively located by means of the EDS and the measuring current transformer connected to it. The locating current flows from the locating current injector via the live lines
to the insulation fault position taking the shortest way. From there, it flows through the
insulation fault and the conductor PE back to the ISOMETER®. This locating current pulse
is detected by the measuring current transformer on the insulation fault path and signalled by the connected EDS.
For the duration of the insulation fault location, the function of the insulation monitoring
device is deactivated. If during the insulation fault location the locating current falls
below the value measurable by the EDS, the insulation fault location is ended by the
ISOMETER®.
Risk of malfunctions due to excessive locating current on sensitive
system parts!
The locating current flowing between the IT system and earth can cause
CAUTION
controller faults in sensitive parts of the system, such as the PLC or relay.
Ensure that the level of the locating current is compatible with the system
to be monitored.
3.5 Interfaces
3.6 Self test
After switching on the supply voltage, the ISOMETER, by means of the self-test functions,
automatically and continuously checks all internal measuring functions, the components
of the process control, such as the data and parameter memory, as well as the
connections to the IT system and earth.
The self test can also be activated manually by means of the test button to check the functions of the relays (depending on the configuration) or it can be selected via the "Control"
menu (refer to “Control” on page 55).
The progress of the manual self test is shown on the LC display by a bar graph. Depending
on the conditions in the IT system being monitored, the self test is completed after 15...20
seconds. The device then returns to the standard mode (i.e. measurement mode) and the
actual measured value will be displayed after the measuring time has expired. The display
shows the message
Initial measurement
“Initial measurement” on page 39).
If a fault is detected during the self test, the respective LEDs of the device light (refer to
“Alarm messages” on page 69). In addition, the respective message will be indicated on
the display and a previously programmed output will provide the respective signal.

Consider the minimum distance to adjacent devices: lateral 0 mm, top 20 mm, bottom
20 mm.
According to IEC 60364 (VDE 0100), only qualified personnel are permitted to carry out the work necessary to install, commission and run a device or system.
Danger of electrocution due to electric shock!
Touching live parts of the system carries the risk of:
• A life threatening electric shock
DANGER
DANGER
• Damage to the electrical installation
• Destruction of the device
Before installing and connecting the device, make sure that the installation has been de-energised. Observe the rules for working on elec-
trical installations.
Danger of electric shock!
High voltage can be applied to the terminals L1/+ to L3/- which can be lethal if directly contacted.
• Make sure that the terminal covers are properly mounted and clicked in
before you use the device.
• If the device is connected via terminals L1/+, L2, L3/- to an IT system
that is live for operational reasons, terminals KE and E must not be disconnected from the protective earth conductor (PE).

CAUTION
Provide line protection!
According to IEC 60364-4-43, a line protection shall be provided for the
supply voltage.
Risk of injury from sharp-edged terminals!
Risk of lacerations. Touch the enclosure and the terminals with due care.
Ensure disconnection from the IT system!
When insulation or voltage tests are to be carried out, the device must be
isolated from the system for the test period. Otherwise the device may be
damaged.
Risk of property damage due to unprofessional installation!
Make sure that only one insulation monitoring device is connected in
each conductively connected system. If several devices are connected, the
device does not function and does not signal insulation faults. As a result,
the system can be damaged.
Risk of property damage due to unprofessional installation!
Load currents can result in damage to property and personal injury. For
this reason, do not run any load current through the terminals. The connecting lines L1/+, L2, L3/- to the system to be monitored must be carried
out as spur lines.

Check proper connection!
Prior to commissioning of the installation, check that the device has been
properly connected and check the device functions. Perform a functional
test using an earth fault via a suitable resistance.
Prevent measurement errors!
When an AC system being monitored contains galvanically coupled DC
circuits, take into consideration that: An insulation fault can only be detected correctly when the rectifier valves carry a minimum current of
> 10 mA.
For UL applications:
Only use 60/75°C copper lines!
UL and CSA applications require the supply voltage to be protected via
5 A fuses.
6.2 Connection to a 3(N)AC system

7. Commissioning
Commissioning
7.1 General initial commissioning process
1. Check that the ISOMETER® is properly connected to the system to be monitored.
2. Connect the supply voltage to the ISOMETER®. Adjust the device using the commissioning wizard. Afterwards, the ISOMETER® performs a self test in four steps. The
alarm relays are not checked during this test. After completion of the test, the measured insulation resistance is shown on the display. If the value exceeds the response
values indicated in the lowest line of the display, the message "OK" will additionally
be displayed.
For customer-specific configured devices, the commissioning wizard
might be deactivated and cannot be run. In this case, the device is preset.
However, the commissioning wizard can be started as described at
“Commissioning EDS” on page 34.
3. Check the ISOMETER® in the system being monitored, e.g. using a suitable resistance to earth.
Observe the device status!
The device is in the alarm state until initial commissioning has been
complete.
After setting the response value R
for Alarm 2, the device starts a self-test, makes the
an2
first measurement and outputs the measured insulation resistance values of the IT system being monitored, then commissioning is completed.

8.8 ISOnet mode
The ISOMETER® displays the message "ISOnet active" when the ISOMETER® is in ISOnet
mode, but it does not make any measurements.
In this state, The "ON" LED lights continuously and
the bar indicating the measurement progress is not pulsing.
8.9 Automatic test
A blinking "ON" LED and the bar indicating the measurement progress is pulsing (see
bottom right of the display) indicates that the ISOMETER® is actively measuring in ISOnet
mode.
The ISOMETER® first performs a self test. During this test, the connection to the IT system
and to earth are checked. Following this, the ISOMETER® takes an initial measurement
and records all measured values (see Page 39).
Hereafter, the ISOMETER® measures for one measuring cycle and then the authorisation
for insulation measurement is forwarded to the ISOMETER® with the next higher address.

9.2 (2.1.2) Mode
To locate insulation faults, select one of the three available modes for insulation fault
location.
•Manual
•auto
•1 cycle
In manual mode, the insulation fault location does not start automatically.
If you start the insulation fault location, it remains active without considering the insulation resistance and the alarm message of the ISOMETER®.
In auto mode, the insulation fault location starts automatically as soon as
the response value of alarm 2 of the ISOMETER® has fallen below the preset value. The insulation fault location is cyclically interrupted for an insulation measurement. If the insulation fault still exists after the interruption,
the insulation fault location starts again. The insulation fault location only
stops if alarm 2 is inactive. If a new insulation fault appears, the insulation
fault location restarts automatically.
In 1-cycle mode, the insulation fault location starts automatically as soon
as the response value of alarm 2 of the ISOMETER® has fallen below the
preset value. The insulation fault location is stopped after one cycle.
If the insulation fault still exists after the interruption, the insulation fault
location does NOT start again. If a new insulation fault appears, the insulation fault location restarts automatically for one cycle.

10. Device communication
Device communication
10.1 Ethernet interface
The Ethernet interface can be used for communication with Modbus, web server and
BCOM.
10.2 BCOM
BCOM is intended for communication between Bender devices via Ethernet.
In order to guarantee that all devices are able to communicate via BCOM, all devices must
have the same system name. Devices can be organised in subsystems. Each device requires an individual device address.
For more information regarding BCOM, refer to the BCOM manual (D00256) at
http://www.bender.de/manuals.
When address 0 has been set for the communication via BCOM the device
can be accessed via the network (e. g. for parameter setting, etc.) but it
cannot communicate with other devices.
10.3 Modbus/TCP
Modbus is an international widely used protocol for data transfer between devices.
All measured values, messages and parameters are stored in virtual register addresses.
Data can be read at a specific register address with a read command. With a write command, data can be written to a register address. The register addresses of the individual
measured values und parameters can be found in the manual "iso685-D Annex A" with
the title "ISOMETER® iso685 device family - Modbus settings" at http://www.bender.de/
manuals.
A maximum of 5 TCP/IP connections can be used simultaneously.
10.4 Web server
The ISOMETER® has an integrated web server, which conveniently displays ISOMETER®
data on every PC via a web browser. The web server can be used to read measured values
and parameterise the ISOMETER® .
To access the web server, enter the IP address of the ISOMETER® into the web browser.
For example:http://192.168.0.5). The ISOMETER® IP address can be found in the "Info"
menu (refer to 9.1 (7.0) "Info" on page 58).
The following web browsers should be used:
The web server offers the following functions:
• Visualisation
• Indication of device information (e.g. device type, software version, etc.)
• Indication of current device settings.
• Indication of alarm messages.
• Indication of the Modbus information of the individual parameters.
• Indication of the interfaces in use.
• Overview of the current measured values.
• Detailed graphic representation of the insulation resistance (isoGraph).
• Fast and simple visualisation without any programming.
• Parameter setting
• Easy and fast parameter setting of the device
• Easy assignment and editing options for devices
• Maintenance
• Data storage of specific events for fast support by Bender Service.
59
In order to be able to parameterise the device externally via Modbus, the
menu item "Allow" must have been set in the "Write access" menu (see
“Write access” on page 57).
A maximum of 5 TCP/IP connections can be used simultaneously.
Only one device may access the web server at the same time. If several devices try to access the web server it may result in timeouts.

10.5 BS bus
The BS bus is used to extend Bender measuring devices (e.g. ISOMETER®) It is an RS-485 interface with a specially developed protocol for Bender devices. On the BS bus, the transmission of alarm messages takes priority over the transmission of all other messages. For
further information, refer to the BS bus manual (document number: D00278) at
www.bender.de/manuals
When using interface converters, a galvanic separation is required.
CAUTION
The compatibility of the BS bus and the BMS bus is restricted!
10.5.1 Master-slave principle
The BS bus works according to the master-slave principle. This means that the measuring
device operates as the MASTER, while all sensor devices operate as SLAVES. The master is
responsible for the communication necessary for the measuring function. It also provides
the required bus bias voltage for the operation of the BS bus.
10.5.2 Addresses and address ranges on the BS bus
Address 1 is assigned to the master. All sensor devices receive unique addresses starting
with address 2, assigned in consecutive order without gaps. In the event of a device failure, a maximum gap of 5 addresses is permissible.
.
10.5.4 Cable routing
The optimum cable routing for the BS bus is a double-terminated bus topology. The
length of the branch line is limited to 1 m. These branch lines do not have to be
terminated.
Bus topology examples:
Termination
1Master
2 Slave Terminating resistor deactivated via switch on device (OFF)
3Slave
CAUTION
Terminating resistor activated via switch on device (ON) or external terminating resistor between terminals A and B
Terminating resistor activated via switch on device (ON) or external terminating resistor between terminals A and B
Only the first and last device may be terminated. Therefore, check all
devices.
10.5.3 RS-485 specifications/cables
The RS-485 specification restricts the cable length to 1200 m
connection. The number of devices on the BS bus is only limited by the BS bus master.
Use twisted pair, shielded cables for bus cabling. For example, cable type J-Y(St)Y
n x 2 x 0.8 is suitable. The shield must have a single-ended connection to earth. The BS
bus must be terminated at both ends with terminating resistors (120 , 0.25 W). The terminating resistors are connected in parallel to the terminals A and B. Some devices feature integrated terminating resistors and can be activated or deactivated via the "R"
button.

Description
Main circuits without dynamic frequency changes.
The universal profile is suitable for all systems primarily with constant
mains frequencies and extraneous DC voltages. When using inverters and
dynamic frequency control, select inverters > 10 Hz or inverters < 10 Hz.
This profile is used to reduce the measurement voltage to ±10 V in control
systems with lower nominal voltages in order to reduce the impact by the
ISOMETER® on sensitive switching elements.
This profile allows the realisation of a very fast measuring time, e.g. as
required for generator monitoring. Furthermore, this profile can be used
to support fast fault localisation in an IT system. The generator profile is
suitable for AC systems containing DC components.
For systems with high leakage capacitances, e.g. ship applications, the
impact of leakage capacitances on the measuring result can be significantly reduced by selecting this profile.
This profile is used for systems with dynamic frequency control by inverters in the range 10 to 460 Hz in order to optimise the measurement with
respect to the measuring time and quality.
For systems involving extremely low frequency control in the range of up
to 0.1...460 Hz and very low and continuously changing extraneous DC
voltages due to dynamic load conditions in an IT system, continuous insulation monitoring can be optimised
Allows Bender service to make customer-specific settings. If no settings
are made by Bender service, then the profile has the same parameters as
the "Power circuits" profile.

Special functions for coupled IT systems
Special functions for coupled IT systems
12.1 Particularities when monitoring coupled IT systems
When using ISOMETER®s in IT systems, make sure that only ONE active ISOMETER® is connected in each galvanically interconnected system. If several ISOMETER®s are to be connected to the IT system, ensure that only one ISOMETER® is active in the IT system via
system isolation using the digital input or Ethernet (ISOnet function).
If IT systems are interconnected via coupling switches, make sure that ISOMETER®s not
currently used are disconnected from the IT system and deactivated.
IT systems coupled via diodes or capacitances may also influence the insulation monitoring process so that a central control of the different ISOMETER®s is required.
12.2 System isolation via digital input with two coupled systems
The coupling switch must have a free contact so that the ISOMETER®
iso685–x–P can be deactivated via one of the digital inputs.
Via the X1 connector, the ISOMETER® can be isolated from the IT system and the measuring functions can be deactivated. Therefore, the function of the digital input in use has to
be set to "device inactive".
If the digital input used for this function is selected, the connectors L1/+, L2, L3/- are
deactivated via internal system isolating switches, the measuring function stops and the
following message appears on the display: "Device inactive. Device disconnected".
Stored fault messages are reset when the cause of the fault has been eliminated (Reset
function).
If the digital input is no longer selected, first the connection to the IT system is restored
and afterwards, an entirely new measuring cycle for the insulation monitoring starts.
This function can be used to disconnect the second ISOMETER® selectively in coupled IT
systems via the auxiliary contact of the coupling switch.

12.3 System separation via ISOnet
The ISOnet function ensures via an Ethernet connection that only one ISOMETER® of the
interconnection is active when several ISOMETER®s are connected to an IT system.
For several ISOMETER®s to be able to measure in the same ISOnet interconnection, the settings for the BCOM system name and the BCOM subsystem have to be the same. Only the device address has to be different. If
CAUTION
this is not taken into account, the ISOnet function will not work.
If the ISOnet function is deactivated in an ISOMETER® in an ISOnet interconnection, it will measure continuously and will not forward measuring
commands to the next device in the interconnection.
In comparison to a solution with coupling switches and function input,
the response time will be extended because the measurement in the IT
system is not carried out continuously.
The addresses of the ISOMETER®s in the ISOnet interconnection can be selected at will. The addresses do not have to be subsequent but they have
to differ from each other.
If in addition to the ISOnet interconnection the digital inputs are wired
and a device is deactivated via a digital input, the device will forward the
measuring authorisation until the signal at the digital input disappears.
Afterwards, it participates again in the the measuring interconnection.
12.3.1 System structure
The IP address of the standard gateway must suit the subnet mask, so that
the ISOnet function can operate correctly.
64
Maximum number of devices in an ISOnet interconnection: 20 devices
iso685-x-P_D00170_05_M_XXEN/05.2018
Page 65
12.3.2 Configuration and function
For the ISOnet function, the following settings are made in the menu: Alarm settings
-> ISONet -> ISONet = BCOM. The ISOnet function of all ISOMETER®s existing in the
system has to be activated and the number of devices has to be determined - this can be
carried out in the menu Alarm settings ->Number of participants.
Also the parameters of the Ethernet (DHCP on or IP address, sub net mask and default
gateway) and BCOM have to be set so that the devices in the ISOnet interconnection can
communicate with each other.
After starting the system, the devices initialise. The initialisation phase ends when the
configured number of devices has been reached. Then, the device starts with a measuring cycle with the smallest address. When an ISOMETER® has finished one measuring cycle, the authorisation for insulation measurement is forwarded to the ISOMETER® with the
next higher address. While one ISOMETER® is measuring, all other ISOMETER®s are isolated from the system via internal system isolation switches.By limiting to one subsystem it
is possible to have several ISOnet interconnections running in one system.
If a single device fails, the remaining ISOMETER®s continue the ISOnet operation. For the
failure of one device, two scenarios are possible:
• A device fails during the measuring process.
After timeout, another device takes over the measuring function.
In this way, all devices monitor each other.
• The device fails in the inactive mode.
When forwarding the measuring authorisation, the device is skipped and the next
device carries out the measurement.
If a device that has failed before returns, it is taken into the interconnection again and will
have its turn during the next run.

13. Insulation fault location
Insulation fault location
13.1 General description
An additional function of the ISOMETER® in combination with the EDS is the selective insulation fault location. The insulation faults detected in the IT system by the ISOMETER®
can be located by means of an EDS and a measuring current transformer.
For further information regarding the function principle of the insulation fault location,
refer to 3.4 "Insulation fault location" on page 13.
13.2 Required settings for insulation fault location
Connecting and commissioning the system consisting of ISOMETER® and EDS
correctly.
For further information regarding the connection of the EDS, refer to 6.11 “Connecting
the EDS to the ISOMETER®” from page 26, at7.2 "Commissioning procedure - steps for
commissioning" on page 32 and to the corresponding manual of the EDS.
Setting locating current and EDS mode.
These settings can be made either during initial commissioning
(see 7.1 “General initial commissioning process” from page 32) or in the device menu of
the ISOMETER® (see 9.1 (2.0) “EDS (insulation fault location)” from page 49).
For further information regarding the locating current for insulation fault location, refer
to 9.2 (2.1.1) "Current" on page 49.
For further information regarding EDS modes, refer to 9.2 (2.1.2) "Mode" on page 50.
13.3 Indication on the display
13.4 Starting and stopping the insulation fault location
The insulation fault location can be started and stopped via different interfaces:
• Shortcut button "EDS"
Manually starts/stops the insulation fault location, which runs continuously. If the
device is started continuously, it measures until it is manually stopped via the shortcut button (see “Display elements and device buttons” on page 17).
• Device menu
• Modbus
• Web server
• Digital input
For further information regarding start and stop conditions of the insulation fault location, refer to 9.2 (2.1.2) "Mode" on page 50.
The active insulation fault location is indicated on the display of the ISOMETER®.
For further information, refer to 8.7 “Initial measurement” from page 39.

insulation fault x mA
Interference CT connection
CT short circuit
Residual current
Possible causes:
• Low-frequency residual currents
• External magnetic fields
If an insulation fault is located, the message Insulation
fault 5 mA appears on the display. The level of the locat-
ing current gives information regarding the faulty out-
going circuit. The higher the locating current, the lower
the insulation resistance on the detected channel.
A measuring current transformer has not been con-
nected correctly or does not work.
Connection fault of CTs
Possible causes:
• Measuring current transformer defective
• Power supply cable short-circuited
The set response value of the residual current has been
exceeded on one channel.
• Identify interference sources and eliminate them
• Determine cause of the insulation fault and eliminate it.
• Check wiring of the measuring current transformers
• Check device function
• Start new search for EDS channels
• Deactivate channel without CT
• Replace defective measuring current transformer
• Check cables
• Determine cause of the exceeded residual current and eliminate

18. Glossary
BB bus
BCOM Protocol for communication between Bender devices via an IP-based network.
BS bus The Bender sensor bus is an interface which enables Bender devices to communicate with each other (RS-485 interface).
DHCP Dynamic Host Configuration Protocol. It is used to assign the network configuration to Clients via a server.
EDS Insulation fault locator for fault location in an IT system.
EDS button
EDS mode
ISOnet
Modbus TCP Modbus is an international widely spread protocol for data transfer.
PGH
"PGH ON" LED The "PGH ON" LED flashes during insulation fault location. It indicates that the locating current for the insulation fault location is generated.
System (BCOM)
Subsystem (BCOM)
Web server A web server presents the device functions graphically. The web server can be used for reading out measured values and for parameter setting.
The BB bus is an interface which enables Bender devices to communicate with each other (Bender-internal device bus).
The BB bus can be used with an ISOMETER® and one or more EDS44…-S.
The shortcut button "EDS" manually starts the insulation fault location, which runs continuously until the button is pressed again, which stops the
process immediately.
(refer also to “Display elements and device buttons” on page 17).
The insulation fault location can be carried out in three different modes. Depending on the mode, the insulation fault location starts and stops due
to different conditions (see also “Mode” on page 50).
Only one ISOMETER® may exist in an isolated system. If several networks monitored by an ISOMETER® are coupled, this function ensures via an
Ethernet connection that only one ISOMETER® is actively measuring.
PGH stands for locating current injector. The locating current injector generates a periodic locating current for insulation fault location. This locating current is detected by the measuring current transformers connected to the EDS and evaluated by the EDS.
The system is the entire installation that is visible for the customer and defined by the customer. The BCOM communication takes place within this
system. Naturally, different systems can exist independently in one network.
The subsystem structures parts of the system as units defined by the customer, e.g. all PQ devices. A typical subsystem are also "non BCOM-capable" devices that are hidden behind a proxy.
