This operation manual only describes how to operate the device using the 6 buttons. The GridVis® network analysis software has its own "online help".

4. 3 GridVis® network analysis software

You can use the GridVis® network analysis software that is available at www.janitza. de to program the device and read out data. To do this, a PC must be connected to the device via a serial interface (RS485/ Ethernet).

You can use the GridVis® network analysis software to:

• program the device.

• conﬁgure and read out recordings.

• analyse the read out data according to EN 61000-2-4.

• save the data to a database.

• display measured values graphically.

• program customer-speciﬁc applications.

CAUTION!

If the device is connected incorrectly, incorrect measured values may be returned.

Therefore, note the following:

• Measured voltages and measured currents must derive from the same network.

• Do not use the device to measure DC current.

• Earth active switchboards.

Malfunctions due

7. 6 Current measurement

The device:

• is intended for connecting current transformers with secondary currents of ../1 A and ../5 A.

• does not measure DC.

• has current measurement inputs that are loaded with 120 A for 1 second.

The factory-set current transformer ratio is 5/5 A and must be adapted to the current transformer employed if necessary.

L1 N PEL3L2

WARNING!

to electric voltage

on current transformers!

On current transformers that are operated open on the secondary side, high voltage peaks that are dangerous to touch can occur, which can cause severe bodily injuries or death.

Therefore, note the following:

• Avoid operating the current transformers open.

• Short circuit all unloaded current transformers.

• Connect the earthing connections

provided on the current transformer to the earth.

• You must short circuit the secondary connections on the current transformer before interrupting the power supply.

• If a test switch, which automatically short-circuits the secondary wires of the current transformer is available, it is sufﬁcient to set this to the "Test" position as long as the short-circuiting device has been checked beforehand.

• Only use current transformers that have a basic insulation in accordance with IEC 61010-1:2010.

• Ensure that the attached screwtype terminal is afﬁxed to the device sufﬁciently using the two screws.

• Safe open-circuit current transformers are also dangerous to touch when they are operated open.

Risk of injury due

Fig. "Current measurement via current transformers"

connection example.

WARNING!

Risk of injury due

to electric voltage!

Temperatures of up to 80 °C can occur on the connections if there are high measured currents.

Therefore, use lines that are designed for an operating temperature of at least 80 °C

UMG 509-PRO www.janitza.com

7. 6. 2 Current direction

You can correct the current direction on the device or via the existing serial interfaces for each phase individually. If the connection is incorrect, a subsequent re-connection of the current transformer is not required.

7. 6. 3 Total current measurement

For a summation measurement via two current transformers, ﬁrst set their total transformation ratio on the device. For information on setting the current transformer ratios, see “11. 3. 1 Measuring transducer”.

Example:

The current is measured via two current transformers. Both current transformers have a transformation ratio of 1000/5 A. The summation measurement is performed using a 5+5/5 A total current transformer.

The device must then be set up as follows:

Primary current: 1000 A + 1000 A = 2000 A Secondary current:

5 A

7. 6. 1 Ammeter

If you wish to measure the current not only with the UMG but rather with an ammeter too, connect the ammeter to the UMG in series.

7. 8 Residual current monitoring

The device:

• is suitable for use as a residual current monitoring device (RCM) as well as for monitoring AC, pulsing DC, and DC.

• can measure residual currents in accordance with IEC/TR 60755 (2008-01)

of type A.

The connection of suitable external residual current transformers with a rated current of 30 mA is performed via the residual current transformer inputs I5 (terminals 4/5) and I6 (terminals 6/7).

7. 8. 1 Failure monitoring

The device monitors the ohmic resistance at the residual current measurement inputs.

If this is greater than 300 Ohm, residual current monitoring fails. This can occur due to a cable break for example

For further information on failure monitoring, see section “12. 7 Failure monitoring (RCM)”.

Fig. “Residual current monitoring via current trans-

formers” connection variant

NOTE!

The transformation ratios for the residual current transformer inputs can be conﬁgured via the GridVis® software. (see www.janitza.com)

NOTE!

It is not necessary to conﬁgure a connection schematic for measurement inputs I5 and I6!

Load

CAUTION!

Insufﬁcient insulation of the operating equipment on the analogue inputs (temperature measurement and residual current monitoring) to the mains supply circuits can cause hazardous voltages on these inputs.

Ensure that there is reinforced or double insulation to the mains supply circuits!

Risk of injury due to

high voltage

www.janitza.com UMG 509-PRO

7. 8. 2 Example: Residual current transformer insulation

A residual current transformer should measure on isolated mains cables within a 300 V CAT III network.

The insulation of the mains cables and the insulation of the residual current transformer must fulﬁl the basic insulation requirements for 300 V CAT III. This equates to a test voltage of 1500 V AC (duration 1 min.) for the insulated mains cables and a test voltage of 1500 V AC (duration 1 min.) for the residual current transformer.

8. 4 Bus structure

• All devices are connected in a bus structure (line).

• Each device has its own address within the bus (also see „11. 8 Proﬁbus Konﬁguration“).

• Up to 32 participants can be connected together in a single segment.

• The cable is terminated with resistors (bus terminator, 120 Ohm, 1/4 W) at the beginning and at the end of a segment.

• If there are more than 32 participants, repeaters (ampliﬁers) must be used to connect the individual segments.

• Devices for which the bus connection is switched on must be under current.

• It is recommended that the master be placed at the end of a segment.

• If the master is replaced with a bus connection, the bus must be switched off.

• Replacing a slave with a bus connection that is either switched off or de-energised can destabilise the bus.

• Devices that are not connected to the bus can be replaced without destabilising the bus.

The device has two digital outputs, which:

• are galvanically separated from the analysis electronics using opto couplers.

• have a joint consumption.

• can switch DC loads.

• require an external auxiliary voltage.

• can be used as pulse outputs.

CAUTION!

When using the digital outputs as pulse outputs, measurement errors may arise due to the residual ripple.

Therefore, use a mains adapter for the supply voltage for the digital inputs and outputs, which has a residual ripple of less than 5% of the supply voltage.

CAUTION!

The digital outputs are not short-circuit proof! Connection errors can therefore cause damage to the connections.

Ensure that the wiring is correct when connecting the outputs.

12. Commissioning

This section provides you with all the information you require to commission your device for the ﬁrst time.

12. 1 Connecting the supply voltage

Proceed as follows when setting up the supply voltage:

1. Connect the supply voltage to the rear of the device using a terminal.

2. After connecting the supply voltage, the ﬁrst measured value indication, Home, appears on the display.

3. If no display appears, check whether the supply voltage is within the rated voltage range.

CAUTION!

Failure to observe the connection conditions can damage or destroy your device.

Therefore, note the following:

• Adhere to the speciﬁcations for voltage and frequency on the rating plate.

• Do not use the device to measure DC voltage.

Damage to property

due to not observing

the connection conditions

12. 2 Connecting the measured voltage

Proceed as follows when connecting measured voltage:

1. Connect the measured voltage to the rear of the device using a terminal.

2. After connecting the measured voltage, the measured values displayed by the device for the L-N and L-L voltages must correspond to those on the measurement input.

3. Pay attention to any voltage transformer factors that are set.

WARNING!

If the device is subjected to surge voltages higher than the overvoltage category, safety-relevant insulations in the device can be damaged, which means that the product’s safety can no longer be guaranteed.

Only use the device in environments in which the permissible overvoltage category is not exceeded.

Risk of injury due to electric voltage!

www.janitza.de UMG 509-PRO

12. 3 Frequency measurement

To measure, the device requires mains frequency that can either be speciﬁed by the user or determined automatically by the device.

• In order to determine the frequency automatically, at least a voltage (V-Vref) of greater than 10 Veff must be applied to at least one of the voltage measurement inputs.

• The mains frequency must be in the range from 40 Hz to 70 Hz.

• If there is no sufﬁciently high measured voltage available, the device cannot determine the mains frequency and therefore cannot perform any measurements.

12. 4 Phase sequence

Check the direction of the rotating ﬁeld voltage in the measured value indication of the device. A “right-hand” rotation ﬁeld usually exists.

UL1-UL2-UL3 = right rotation ﬁeld UL1-UL3-UL2 = left rotation ﬁeld

Fig. Indication of the phase sequence according

to the direction of the rotating ﬁeld.

UMG 509-PRO www.janitza.de

12. 5 Applying the measured current

The device:

• is intended for connecting current transformers with secondary currents of ../1 A and ../5 A.

• does not measure DC.

• has current measurement inputs that are loaded with 120 A for 1 second.

The factory-set current transformer ratio is 5/5 A and must be adapted to the current transformer employed if necessary.

Proceed as follows when connecting the measured voltage:

Fig. Phasor diagram

Voltage (shown with a long phasor)

1. Short circuit all current transformer outputs except for one.

2. Connect the measured voltage via the terminals on the back of the device and afﬁx it sufﬁciently with two screws.

3. Compare the current displayed on the device with the current input.

• The currents must match based on the current transformer conversion ratio.

• The device must display approx. zero amperes in the short circuited current measurement inputs.

Phase shift angle sign preﬁx (U/I):

• positive (+) for capacitive load

• negative (-) for inductive load

Current (shown with a short phasor)

NOTE!

Voltages and currents that are outside the permissible metering range can damage the device.

www.janitza.de UMG 509-PRO

12. 5. 1 Phasor diagram examples

The following are two examples for an indication of measured current and measured voltage in the phasor diagram:

Example 1

Predominantly ohmic load.

Voltage and current only

have a minor deviation in the phase length.

• The current measurement input is assigned to the correct voltage measurement input

Example 2

Predominantly ohmic load.

Voltage and current have

a deviation of about 180° in the phase position.

• The measurement input is assigned to the correct voltage measurement input.

• In the current measurement considered here, the k and l connections are reversed or there is a return feed in the mains power supply.

12. 6 Applying the residual current

Only connect residual current transformers with a rated current of 30 mA to inputs I5 and I6!

Both residual current inputs can measure AC currents, pulsing direct currents and DC currents.

Bearing in mind the current transformer ratio, the residual current displayed by the device must correspond to the current input.

The current transformer ratio is factory-set to 127/1 A and must be adapted to the residual current transformer used if necessary.

NOTE!

It is not necessary to conﬁgure a connection schematic for measurement inputs I5 and I6!

NOTE!

The device requires the mains frequency to measure the residual currents. Establish a measured voltage for this or set a ﬁxed frequency.

UMG 509-PRO www.janitza.de

12. 7 Failure monitoring (RCM)

The device enables continuous monitoring of the connection to the residual current transformer on inputs I5 and I6.

You can activate failure monitoring via:

• the relevant menu item as described in section “11. 3. 1 Measuring transducer”.

• or by setting address 18895 for residual current measurement input I5 and 18897 for I6.

If there is an interruption in the connection to the current transformer, this state is recorded in certain registers or indicated in the GridVis® software.

12. 7. 1 Alarm status

Using bit-by-bit coding inside the alarm register (addr. 19224 for I5, 19225 for I6), it is possible to read out different alarm statuses:

Fig. Indication of values exceeding the measurement

range in voltage circuit L2 and in current path I4

12. 9 Checking the power measurement

1. Short circuit all current transformer outputs except for one.

2. Check the powers displayed.

• The device may only display one power output in the phase with a non-shortcircuited current transformer input.

• If this is not the case, check the connection of the measured voltage and the measuring-circuit current.

If the active power amount is correct but the sign of the power output is negative, this could have two possible causes:

Ideally, the number of errors displayed in the error column is zero.

You can reset the counter for the data packages to 0 by pressing button 6. The start time for the new counting process is reset automatically.

12. 11. 2 Proﬁbus

Proﬁbus proﬁles

A Proﬁbus proﬁle contains the data to be exchanged between a UMG and a PLC. Four Proﬁbus proﬁles are preconﬁgured at the factory.

You can use the Proﬁbus proﬁle to:

• retrieve measured values from the UMG,

• set the digital outputs in the UMG,

• query the status of the digital inputs in the UMG.

Each Proﬁbus proﬁle can hold a maximum of 127 bytes of data. If more data has to be transferred, simply create additional Proﬁbus proﬁles. Every Proﬁbus proﬁle has a proﬁle number. The proﬁle number is sent by the PLC to the UMG.

You can use GridVis® to edit 16 Proﬁbus proﬁles (proﬁle numbers 0 - 15) directly. Additional Proﬁbus proﬁles (proﬁle numbers 16 to 255) can be created using Jasic programs.

Device master ﬁle

The device master ﬁle, abbreviated as the GSD ﬁle, describes the Proﬁbus characteristics of the UMG. The GSD ﬁle is required by the conﬁguration program of the PLC. The device master ﬁle for your device has the ﬁle name "U5090F15.GSD" and is available on the Janitza homepage.

Variable deﬁnition

All system variables and global variables1) can be individually scaled and converted into one of the following formats:

• 8, 16, 32 bit integer with and without sign.

• 32 or 64 bit ﬂoat format.

• Big endian = High byte before low byte.

• Little endian = Low byte before high byte.

Global variables are deﬁned by the user in Jasic and are available to each

interface in the device.

Factory pre-conﬁgured Proﬁbus proﬁles cannot be subsequently changed.

UMG 509-PRO www.janitza.de

Example: Using Proﬁbus to retrieve

measured values

You must use the GridVis® software to deﬁne at least one Proﬁbus proﬁle and transfer this to the device.

A Jasic program is not required.

Digital Inputs

12. 12 Digital inputs/outputs

Your device has two digital outputs and two digital inputs.

Fig.: Digital outputs and inputs

The inputs and outputs can be conﬁgured using the GridVis® software supplied as standard.

12. 12. 1 Digital inputs

You can use the digital inputs to send information from other devices that have a digital output to your device directly.

You can use the conﬁguration window in GridVis® to deﬁne the input range for both digital inputs:

12. 12. 2 Pulse output

The digital outputs can be used for the output of pulses for the computation of power consumption. For this purpose, a pulse of deﬁned length is applied on the output after reaching a certain, adjustable amount of power.

You must make various adjustments in the conﬁguration menu using the GridVis® software to use a digital output as a pulse output:

• pulse width

• digital output that is to be conﬁgured,

• output type (event notiﬁcation or S0 output)

• the measured value to be transferred

• pulse value

• The value type that the incoming signal has.

• The scaling factor that is to be used for the value.

Fig. Conﬁguring the UMG 509-PRO inputs via GridVis®.

Fig. Conﬁguring the UMG 509-PRO digital outputs via

GridVis®.

www.janitza.de UMG 509-PRO

Pulse length

The pulse length applies to both pulse outputs and is set using the GridVis® software. The typical pulse length for S0 pulses is 30ms.

Pulse interval

The pulse interval is at least as large as the selected pulse length. The pulse interval depends on the measured power, for example, and can take hours or days.

Pulse length 10ms to 10s

Fig. Schematic illustration of a digital pulse

The values in the table are based on the minimum pulse length and the minimum pulse interval for the maximum number of pulses per hour.

Max. pulse/h

Pulse value

The pulse value is used to indicate how much power (Wh or varh) should correspond to a pulse.

The pulse value is determined bythe maximum connected load and the maximum number of pulses per hour.

If you specify a pulse value with a:

• positive sign, the pulses will only be emitted when the measured value hasa positive sign.

• negative sign, the pulses will only beemitted when the measured value has a negative sign.

NOTE!

Since the effective energy meter operates with a backstop, pulses will only be generated when drawing electricity.

NOTE!

Since the reactive energy meter operates with a backstop, pulses will only be generated with inductive load applied.

Table Examples of the maximum possible number

of pulses per hour

NOTE!

The pulse interval is proportional to the power output within the selected settings.

NOTE!

When programming with GridVis®, you receive a selection of work values which are derived from the power output values. (see www.janitza.de)

UMG 509-PRO www.janitza.de

Determine the pulse value

1. Set the pulse length in accordance with the requirements of the connected pulse receiver. For example, if the pulse length is 30 ms, the device generates a maximum number of 60000 pulses (see "maximum number of pulses" per hour table).

2. Determine the maximum connected load.

Example: Current transformer = 150/5 A Voltage L-N = max. 300 V

Power per phase = 150 A x 300 V = 45 kW Power at 3 phases = 45 kW x 3 Max. connected load = 135 kW

3. Calculate the pulse value:

Pulse value =

max. connected load

max. number of pulses/h

[Pulse/Wh]

CAUTION!

Measurement errors when

using as a pulse output

When using the digital outputs as pulse outputs, measurement errors may arise due to the residual ripple.

Therefore, use a mains adapter for the supply voltage for the digital inputs and outputs, which has a residual ripple of less than 5% of the supply voltage.

Pulse value = 135 kW / 60000 Imp/h Pulse value = 0.00225 pulses/kWh Pulse value = 2.25 pulses/Wh
