Load

The basic device with module is suitable for use as a residual current monitoring device (RCM) for monitoring alternating currents, pulsating direct currents and direct currents.

With the monitoring of residual currents (RCM, Residual Current Monitor) of an electrical system via inputs I5 and I6 (terminals 29/30 and 31/32), the basic device with module is able to trigger warning pulses when the limit value is exceeded. The system operator can be alerted before a protective device is triggered. The measurements in medium and high voltage networks are made via current and voltage transformers.

NOTE

· The residual current monitoring monitors the residual currents via external current transformers and, if a threshold value is exceeded, can trigger a warning signal.

· Limit values and warnings for the device or system operator can be conﬁgured easily in the GridVis® software.

NOTE

The basic device with module is not an independent protective device against electric shock!

The basic device with module measures residual currents according to IEC/TR 60755 (2008-01) of:

Type A

Type B and Type B+ (enhanced frequency

range) Connection of suitable external residual current transformers with a nominal current of 30 mA can be made on residual current transformer inputs I5 (terminals 29/30) and I6 (terminals 31/32).

6.2 Activate cable break detection (failure monitoring) RCM for I5 and I6.

The basic device with module has a “Cable break detection” feature (failure monitoring). With this feature, the basic device with module monitors the connection to the residual current transformers on the measuring inputs I5 and I6 (module mode Residual current - see chap. 9.2 on page 34).

The cable break detection for I5 and I6:

· Can be activated via Modbus addresses or in

the GridVis

software.

· Is only available in the AC mode.

Modbus addresses for activating the cable break detection (failure monitoring):

6.3 Current direction for the current transformer on I5 and I6.

For residual current measurements at the measuring inputs I5 and I6, the device makes no distinction between the current directions. This means that incorrect connection does not require reconnection afterwards.

NOTE

The device makes no distinction between the current directions of the residual currents. The residual currents of the grid side or load side are not directionally sensitive.

WARNING

Risk of injury due to large currents and high electrical voltage on the current transformers!

Current transformers operated while open on the secondary side (high voltage peaks pose a hazard when touched) can result in severe bodily injury or death.

· Avoid operating the current transformers

while open; short circuit the unloaded transformers!

· Before interrupting the current supply,

· Only use current transformers with basic

insulation to IEC 61010-1:2010!

· Caution, even current transformers rated as

safe for open operation can pose a hazard when touched during operation while open!

· Make sure that screw terminals for the

current transformer connection on the device are adequately tightened!

· Comply with the information and provisions

in the documentation of your current transformers!

· Existing ground connections on the

secondary windings of the current transformers must be connected to ground!

· Observe the general safety information for

handling current transformers and devices with residual current measurement in chap.

2.7 on page 10.

· Comply with the information and provisions

in the documentation of your current transformers!

6.4 Residual current transformer example

A residual current transformer is used to measure on insulated mains wiring in a 300 V CAT III network.

Solution:

Provide basic insulation for 300 V CAT III for the insulation of the network wiring and the insulation of the residual current transformer. This corresponds to a test voltage of 1500 V AC (1 min. duration) for the insulated network wiring and a test voltage of 1500 V AC (1 min. duration) for the residual current transformer.

6.5 Important information about the residual current inputs

CAUTION

Risk of injury or damage to the device/your system due to short circuit!

· Ensure reinforced or double insulation with

respect to the supply circuits!

· Ensure galvanic isolation of the residual

current measuring inputs from each other!

NOTE

For the residual current monitoring, the basic device with module requires the mains frequency. For this purpose, apply a measured voltage or conﬁgure a ﬁxed frequency.

NOTE

The ratios for the residual current transformer inputs can be conﬁgured individually on the basic device with module, or, along with additional parameters relevant for the module, via the GridVis® network visualization software.

ATTENTION

Damage to the device/your system due to short circuit!

Inadequate insulation of the operating equipment at the analog inputs with respect to the supply circuits can lead to damage of your device or system.

6.10 Analog inputs I5 and I6/U6 – DC power

As an option for measuring the residual current, the basic device with module also permits use of the analog inputs I5 and I6 (U6) for a DC power measurement.

In a DC power measurement, the current channel I6 effectively becomes a voltage measurement input, U6. When a residual current transformer of the type CT-AC/DC Type B+ is connected, it converts an input voltage into an output current signal. The current signal changes proportionately to the measured value of the input variable.

For a DC power measurement, the basic device with module supports input current signals with the values

· 0 ... 20 mA

· 4 ... 20 mA

6.11 Connection example - DC power measurement

ATTENTION

Damage to the device/your system due to short circuit!

Inadequate insulation of the operating equipment at the analog inputs with respect to the supply circuits can lead to damage of your device or system.

L2 L3

S2S1

Because of the missing multiplier with a voltage, only an apparent current measurement is performed during the current measurement input I4 (terminals 35/36). Therefore, no power measurements are possible using this input. The current measurement input I4 of the basic device with module:

· Is only approved for a current measurement using a current transformer (no direct measurement).

· Is designed for the connection of current transformers with secondary currents of ../1 A and ../5 A.

· Has the current transformer ratio set to 5 / 5 A by default.

· Measures alternating currents (no direct currents).

CAUTION

Risk of injury or damage to the device due to high measurement currents at the connections of the current transformers or the current measurement inputs of the device!

High measurement currents can cause temperatures of up to 80 °C (176 °F) on the connections of the current transformers

· Use wiring that is designed for an operating

temperature of at least 80 °C (176 °F)!

· The current transformers can be hot even

after the power supply has been switched off. Allow the connections of the current transformers and the connecting cables to cool down before touching them!

Consumer

· Make sure that screw terminals for the

current transformer connection on the device are adequately tightened!

· Existing ground connections on the

secondary windings of the current transformers must be connected to ground!

· Observe the general safety information for

handling current transformers and devices with residual current measurement in chap.

2.7 on page 10.

When there is an alarm, the following warning alert appears: When there is an alarm, the title bar of your device display is shown in red with the time indicated. It is also possible to activate blinking of the display when there is an alarm using the Modbus editor or the GridVis

software (see table below).

ATTENTION

A disconnected or defective module disrupts the communication with the basic device and leads to a device fault.

If communication between the basic device to the module is lacking or faulty during operation, a warning signal will appear on the display of the basic device.

· Disconnect your system (the basic device)

from the power supply prior to mounting the module.

· Check the positioning of the RCM module. If

necessary, apply slight pressure to press the module onto the basic device until it audibly snaps in.

· Check the display of your basic device (if the

menu item Residual currentis present, the basic device has recognized the module).

· Prior to remounting, it may be necessary

to restart the basic device (chap. “8.3 Restarting the basic device” on page 31).

· If the measures indicated here are

unsuccessful, please contact our support team (www.janitza.de).

· If there is discernible damage, send the

device, component or module back to the manufacturer in compliance with proper transport conditions.

Pressing function button 5 displays a list of all alarms that have occurred, regardless of from which menu window it is pressed. In the alarm list, alarms can be selected and deleted.

Improper handling may cause damage to the module and result in material damage!

The contacts of the module connector can bend or break, which would destroy the module.

Once all alarms have been deleted, the device closes the alarm list and goes to the last menu window.

· Never touch or manipulate the contacts

of the module connector!

· Never use force to press the module

connector plug into the socket!

· When handling, transporting and storing the

module, protect the contacts of the module
