2.2 Product description

The ISOMETER® iso685-D-B/-S-B is an insulation monitoring device for IT systems according to 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).

2.3 Special characteristics ISOMETER® iso685-S-B with front panel

The ISOMETER® iso685-D-B is a device of the iso685 device family with integrated display. This manual applies in full to the ISOMETER® iso685-D-B.

Das ISOMETER® iso685-S-B is the sensor variant of the ISOMETER® iso685-D-B. The only difference is that it does not feature a display. The ISOMETER® iso685-S-B must be used in combination with a front panel because the device is operated via the front panel. The operation of the front panel is similar to the operation of the ISOMETER® iso685-D-B, which is described in this manual.

The ISOMETER® iso685-D-B, which is similar to the combination of ISOMETER® iso685-S-B and front panel (e.g. FP200), is described below.

2.4 Functional description

The insulation monitoring device ISOMETER® iso685-D-B 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 µA range is superimposed onto the system which is recorded and evaluated by a microcontrolled measuring circuit. The measuring time is dependent on the selected measurement profiles, the system leakage capacitance, the insulation resistance and possible system-related disturbances.

iso685-D-B_D00177_01_M_XXEN/01.2016

Page 10

2. Function

The response values and other parameters are set using a commissioning wizard or 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 protected against unauthorised modifications by entering a password. To ensure proper functioning of connection monitoring, the device requires the setting of the system type 3AC, AC or DC and the terminals

To extend the nominal voltage range, different coupling devices are available as accessories which can be selected from a menu where the required adjustments can also be made. The insulation monitoring device iso685 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. Different measurement profiles which can be selected from a setup menu allow optimum adaptation of the measurement technique to the specific application.

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 resp. 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 insulation resistance is at least 25 % above the preset 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.

L1/+, L2, L3/-.

required use of the appropriate

The insulation monitoring device iso685-D-B 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.

2.5 Interfaces

• Communication protocol Modbus/TCP

• BCOM for communication of Bender devices via Ethernet

• Integrated web server for reading out measured values and for parameter setting

2.6 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.

A manual self test can also be activated by means of the test button to check the relay function (depending on the configuration).

The progress of the manual self test is shown on the LCD 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 initial measurement message until the first valid value is measured.

If an error is detected during a self-test, the corresponding device LEDs light (see

“Alarm messages” on page 50). In addition, the appropriate message is displayed

on the LCD and an output, if configured, provides a corresponding signal.

9. Device communication

9.1 Ethernet interface

The Ethernet interface can be used for communication with Modbus, web server and BCOM.

9.2 BCOM

BCOM is intended for communication of Bender devices via Ethernet

All devices that communicate over BCOM 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) on

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.

9.3 Modbus/TCP

Modbus is an international widely spread protocol for data transfer.

All measured values, messages and parameters are stored in virtual register addresses. Data can be read out with a read command on a register address. With a write command, data can be written into a register address. The register addresses of the individual measured values und parameters can be found in the annex "Modbus configuration“ of the ISOMETER® iso685 (D00022) on

http://www.bender.de/manuals.

A maximum of 5 TCP/IP connections can be used simultaneously.

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 34).

9.4 Web server

The web server of the device ISOMETER® iso685 represents the device functions graphically. The web server can be used to read out measured values and also for parameter setting.

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.

10.1 Particularities when monitoring coupled IT systems

10.2 System isolation via digital input with two coupled systems

In order to deactivate the ISOMETER® iso685-D-B via one of the digital inputs, the coupling switch must have a free contact.

The ISOMETER® iso685-D-B kann be isolated from the IT system and the measuring functions can be deactivated via the X1 connector. 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 separated". 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® iso685-D-B selectively in coupled IT systems via the auxiliary contact of the coupling switch.

10.3 System isolation via digital input with several coupled systems

In order to deactivate the ISOMETER® iso685-D-B via one of the digital inputs, the coupling switch must have a free contact.

10.4 System isolation via ISOnet

With several coupled systems, the ISOMETER®s iso685-D-B can be deactivated as described on page 38 Also an additional PLC for selective deactivation is required to ensure that at least one ISOMETER® iso685-D-B per system remains active.

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 this is not taken into account, the ISOnet function will not work.

iso685-D-B_D00177_01_M_XXEN/01.2016

10.

Special functions for coupled IT systems

If the ISOnet function is deactivated on an ISOMETER® in an ISOnet interconnection, it will measure permanently and will not forward measuring comands 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 is not permanently carried out.

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 over 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.

The IP address of the standard gateway must suit the subnet mask, so that the ISOnet function can operate correctly.

Maximum number of devices ISOnet: 5 devices

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.

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 procedure. 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.

The short measuring cycles during ISOnet operation may lead to fluctuating measured values for voltage and frequency measurement.

Description

Main circuits without dynamic frequency changes. The universal profile is suitable for all systems primarily with constant system 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 ± 10 V in control systems with lower nominal voltages in order to reduce the impact by the ISOMETER® iso685-D-B 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…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 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 using this profile.
