Overcurrent protective device for the line protection of the supply voltage

Recommendation for the overcurrent protective device for the line protection of the supply voltage, depending on the variants:

• Option 230 V: 6 - 16 A (Char. B)

• Option 24 V: 1 - 6 A (Char. B)

Recommendation for the maximum number of devices on one miniature circuit breaker, depending on the variants:

• Option 230 V:

• Option 24 V:

ATTENTION!

The circuit breaker serves only as line protection - it does not provide protection for the device!

For one miniature circuit breaker B6A, maximum of 4 devices. For one miniature circuit breaker B16A, maximum of 11 devices.

For one miniature circuit breaker B6A, maximum of 3 devices. For one miniature circuit breaker B16A, maximum of 9 devices.

7. 4 Measured voltage

The device has 3 voltage measurement inputs (V1 to V3) on the back of the device.

7. 4. 1 Overvoltage

The voltage measurement inputs are suitable for measurement in networks in which overvoltage of category 600 V CAT III (voltage measurement surge of 6 kV) may occur.

7. 4. 2 Frequency

The device:

• requires the network frequency to measure and calculate the measurement values.

• is suitable for measurement in networks in which the fundamental oscillation of the voltage is within the range of 45 to 65 Hz.

The network frequency is derived from the measured voltage in phase L1. The sampling rate of the voltage and current measurement inputs is derived from the network frequency.

If the measurements have severely distorted voltages, it will no longer be possible to precisely determine the frequency of the fundamental oscillation of the voltage. I.e. the corresponding network frequency should be stipulated for measured voltages that exhibit severe distortions. (Voltage distortions occur e.g. in measurements of consumers operated with a phase angle control). Current distortions do not affect the determination of the frequency.

Voltage peaks that are extremely dangerous to touch may occur on current transformers operated with an open secondary side that may result in serious bodily harm or death.

For this reason, please note the following:

• De-energise your system before starting work! Check that it has been de-energised!

• Avoid open operation of the current transformers.

• Short-circuit uncharged current transformers.

• The secondary terminals of the current transformer must be short-circuited before the power supply lines are disconnected.

• If a test switch that automatically short-circuits the current transformer secondary leads is available, it is sufﬁcient to put this into the "test" position provided the short-circuiters have been checked beforehand.

• Only use current transformers that have a base insulation as per IEC 61010-1:2010.

• Ensure that the attached screw terminal is sufﬁciently secured to the device with the two screws.

• Even "open-safe" current transformers are dangerous to touch if they are operated openly.

variants

WARNING!

Risk of injury from electric

voltage!

At high measurement currents, temperatures of up to 80 °C can develop at the terminals.

Therefore, use leads that are designed to have an operating temperature of at least 80 °C.

7. 5. 2 Direction of the current

The current direction can be individually corrected on the device or via the serial interfaces for each phase.

In the case of incorrect connection, the current transformer does not need to be subsequently reconnected.

7. 5. 3 Total current measurement

If the current measurement takes place via two current transformers, the total transformer ratio of the current transformer must be programmed on the device. Setting the current transformer ratios is described in Section „Messwandler“.

Example:

The current measurement is performed via two current transformers. Both current transformers have a transformer ratio of 1000/5 A. The total measurement is then carried out with a total current transformer 5+5/5 A .

7. 5. 4 Ammeter

If you want to measure the current not only with the UMG but also with the ammeter, the ammeter must be connected in series to the UMG.

Data GND

RS485 bus

e.g. Connection of further slave devices

CAT cables are not suitable for bus wiring. Use the cable types recommended for this purpose.

8. 1 Screening

Use a drilled and shielded cable for the connections via the interface, and observe the following points for the shielding:

• Earth the screens of all cables that lead to the cabinet where they enter the cabinet.

• Connect the screen over a larger area and in a manner that will conduct well, to a low-noise earth.

• Do NOT connect the screen to terminal C (GND)

• Gather the cables mechanically above the earthing clamp in order to avoid damage due to cable movement.

• Use suitable cable glands to feed the cables into the cabinet - for example armored conduit couplings.

ATTENTION!

CAUTION!

Atmospheric discharge may cause transmission errors and hazardous voltages on the device.

For this reason, please note the following:

• Place the screening on the functional earth (PE) at least once.

• For larger sources of interference, put the frequency inverter in the control cabinet and position the screening as close as possible on the device to the functional earth (PE).

• Maintain a maximum cable length of 12000 m at a baud rate of 38.4 k.

• Use screened cables.

• Position interface leads so they are

spatially separated or additionally insulated from the components carrying network voltage.

Transmission errors and risk of injury result from

electrical interference.

8. 2 Termination resistors

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

The device does not contain any termination resistors.

8. 3 Bus structure

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

• Each device has its own address within the bus (see also Parameter programming).

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

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

• With more that 32 subscribers, repeaters (ampliﬁers) must be used to connect the individual segments.

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

Master

Power supply necessary

Bus terminator on

Slave

• 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 on or de-energised can destabilise the bus.

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

13. Putting the device into service

This section will explain everything you need to know about putting the device into service for the ﬁrst time.

13. 1 Supply voltage

To connect the supply voltage, proceed as follows:

1. Connect the supply voltage to a terminal on the back of the device.

2. After connecting the supply voltage, the ﬁrst measurement value display "Overview" will appear on the display a few seconds later.

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

Material damage may

CAUTION!

Noncompliance with the connection requirements may result in your device being damaged or destroyed.

For this reason, please note the following:

• Comply with the details on voltage and frequency on the ratings plate.

• Do not use the device to measure direct voltage.

result from failure to

comply with the

connection requirements.

13. 2 Measured voltage

Voltage measurements in networks with rated voltages above the maximum stated rated voltage (cf. Section 6.2 Rated Voltages) are to be connected via voltage transformers.

To connect the measured voltage, proceed as follows:

1. Connect the supply voltage to a terminal on the back of the device.

2. After the measured voltage has been connected, the measurement values displayed by the device for the voltages L-N and L-L will have to match those at the measurement input.

3. Consider any utilized voltage transformer factors.

WARNING!

If the device is exposed to voltage surges above the admissible overvoltage category, safety-related insulations in the device may be damaged, whereupon the safety of the product can no longer be guaranteed.

Only use the device in environments in which the admissible surge voltage is not exceeded.

Risk of injury from electric voltage!

ATTENTION!

Delete any production-related energy counter contents, minimum and maximum values, and recordings prior to putting the device into service.

UMG 96-PA www.janitza.de

13. 3 Frequency measurement

To perform this measurement, the device requires the network frequency, which can be either supplied by the user or automatically determined by the device (cf. Section "Conﬁguration").

• The device can only determine the network frequency if there is a voltage L1-N greater than 20 Veff (4-wire measurement) or a voltage L1-L2 greater than 34 Veff (3-wire measurement) at the voltage measurement input V1.

• The network frequency needs to be within the range of 45 Hz to 65 Hz.

• If the measurement voltage is not sufﬁciently high, the network frequency cannot be determined, and subsequently no measurement can be performed.

More information can be found in Section 12 Conﬁguration / Rated frequency"

13. 4 Rotary ﬁeld direction

To do this, open the menu display "Phasor diagram":

• If you are not in the measurement value display "Overview," switch to this view by repeatedly pressing key 1 (Esc).

• Open the main menu with key 1 (Esc).

• With keys 3 () and 4 (), select "Pointer diagram" and conﬁrm your selection with key 6 (Enter).

Fig. Main menu, Selection "Phasor diagram"

Check the direction of the voltage rotary ﬁeld on the measurement value display of the device.

• A "right" rotary ﬁeld is usually available.

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

Fig. Presentation of the phase sequence according to the rotary ﬁeld direction.

www.janitza.de UMG 96-PA

13. 4. 1 Phasor diagram basics

The phasor diagram graphically describes the phase shift / phase angle between the voltage and the current. The pointer rotates around an origin point at a constant speed proportionally to the frequency of the voltage and the current. The pointer diagram therefore describes the current status of the quantities in an alternating current circuit.

Representation of Ohmic resistance:

• Voltage and current have the same phase

Representation of inductance:

• The voltage rushes ahead of the current

• In an "ideal coil," the phase shift is 90°

Representation of capacity:

• The current rushes ahead of the voltage

• In an "ideal condenser," the phase shift is 90°

In a combination of states, the phase angle "current to voltage" values can range from

-90° to +90°.

Voltage and current input monitoring in pointer diagrams:

The phasor diagram can be used to check for incorrect connections to the voltage and current inputs.

Example 1

Primarily Ohmic load.

Voltage and Current only have minor difference in the phase.

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

Example 2

Primarily Ohmic load.

Voltage and Current only have a difference of about 180° in the phase.

13. 5 Measurement current

The device:

• is designed to be connected to current transformers with secondary currents of ../1 A and ../5 A.

• does not measure direct currents.

• has current measurement inputs that can be loaded with 60 A (sinusoidal) for 1 second.

The factory preset current transformer ratio is 5/5 A, and may need to be adjusted to the current transformer in use.

1. Short-circuit all of the current transformer outputs except for one.

2. Compare the current indicated on the device with the attached input current.

• The currents must match when the current transformer conversion ratio is accounted for.

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

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

• In the present current measurement, the connections k and I are switched or energy is being fed back into the supply network.

Fig. phasor diagram

ATTENTION!

Voltages and currents outside of the admissible measurement range can destroy the device.

www.janitza.de UMG 96-PA

13. 6 Measurement range violation

The device display shows the warning "Measurement range violation" in the event of a

measurement range violation and indicates the current/voltage path.

Measurement range violations are displayed for as long as they continue and cannot be acknowledged. There is a measurement range violation if at least one of the voltage or current measurement inputs is outside of its speciﬁed measurement range.

Thresholds for measurement range violation (200 ms effective values):

I = 6 A rms UL-N = 600 V rms

13. 7 Checking the power measurement

Short-circuit all current transformer outputs except one and check the displayed power outputs.

• The device may only display one power output in the phase with the current converter input that is not short-circuited.

• If this does not apply, check the connection of the measurement voltage and measurement current.

If the amount of effective power is correct but the sign of effective power is negative, this may have two causes:

1. The connections S1(k) and S2(l) are switched on the current transformer.

2. Effective power is returned to the network.

13. 10 Harmonics

Harmonics are caused by equipment with nonlinear characteristics. These additional frequencies are integer multiples of a fundamental oscillation, and show how the equipment affect the power grid.

The possible effects of harmonics include:

• additional heating of equipment.

• additional current on the neutral conductor

• an overload and reduced life cycle of electrical usage

Harmonic loads are the primary cause of invisible voltage quality problems associated with enormous repair costs and investment to replace defective devices.

The device measures the fundamental oscillation of the voltage in the range of 45 - 65 Hz. This fundamental oscillation is the basis for the calculation of the harmonics for the voltages and currents.

The device calculates harmonics up to 25 times the fundamental oscillation.

Digital Inputs

13. 12 Digital inputs/outputs

Your device has three digital inputs and three digital outputs.

Fig. Digital inputs and outputs

• You can conﬁgure the inputs and outputs via the GridVis® software.

• The GridVis® software can be found on the homepage (www.janitza.de) in the download area.

13. 12. 1 Digital inputs

It is possible to transmit information from other devices that have a digital output directly to your device via the digital inputs.

It is still possible to conﬁgure the digital inputs as function inputs. In this mode, each digital input has a speciﬁc function. In this conﬁguration it is not possible for these inputs to function as pulse counters!

You can set the digital outputs in the "Periph- ery" area via the conﬁguration window of the GridVis® software:

Function mode

• Which function should be assigned to the digital input.

Pulse counter

• Which value type the incoming signal has (e.g. electrical power, gas and water consumption, CO2 ...)

• Which pulse value should be used for the value.

• How long the transmission time is.

The statuses of the digital inputs are each on their own Modbus address. For each digital input, the last 16 switching operations (events) are logged with a time stamp.

Fig. Conﬁguration of the digital inputs via the GridVis®

software

Function mode

Each digital input can be assigned a speciﬁc function with:

• Digital input 1 Conﬁguration as tariff converter (HT/NT) possible.

• Digital input 2 Synchronization of the internal clock; choosing between minute or hour synchronization is possible. However, synchronization is also possible via a Modbus address.

• Digital input 3 Conﬁguration as reset entry for the synchronization values of the drag indicator function. It is also possible to synchronize the drag indicator via the Modbus address.

UMG 96-PA www.janitza.de

Pulse counter

All digital inputs can be operated with a frequency of 25 Hz. Here, the pulse duration and the pulse interval must be greater than 20 ms. The typical pulse duration for S0 pulses is 30 ms.

Calculation of measurement value:

Measurement value = Pulse x Pulse value

Calculation of power value:

Pulse duration

> 20ms

Pulse pause

> 20ms

The maximum number of pulses per hour is based on the minimum pulse duration and the minimum pulse interval:

Pulse

length

20 ms 20 ms 90 000 pulses/h

30 ms 30 ms 60 000 pulses/h

50 ms 50 ms 36 000 pulses/h

100 ms 100 ms 18 000 pulses/h

500 ms 500 ms 3 600 pulses/h

1 s 1 s 1 800 pulses/h

10 s 10 s 180 pulses/h

Examples of the maximum number of pulses per hour.

Pulse inter-

val

Max. pulses/h

The pulse counters can be conﬁgured with a simultaneous measurement value or power calculation. The pulses are counted as 64-bit numbers and overﬂow after approx. 1.17 x 1010 years of continuous operation (25 Hz).

Pulse value: A pulse value can be assigned to each digital input. Use the impulse value to specify the measurement value or power value (e.g. energy) to which a pulse should correspond.

Power value =

Pulse x Pulse value

Time [sec]

Since the pulse interval may be very large, continual calculation of the measurement or power values is not possible. For this reason, only the mean values are calculated. For measurement value calculation, the mean values are calculated from the number of pulses per period multiplied by the pulse value. For power value calculation, this value must be divided by the amount of time that can be set.

The period is assigned to the digital input and can be set in a range of 1 to 60 minutes. After the period ends, the value can be called via the Modbus.

For each digital input, an external synchronization can be triggered; in this case, a synchronisation pulse completes one period and starts a new period. A ﬁxed capture period of 30 seconds is preset for external synchronization. If no synchronization pulse exists after the period expires, a maximum of 30 seconds is waited and the software then carries out the synchronization. All further periods are synchronized by the software.

A period of 15 min is the factory setting.

ATTENTION!

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

The calculation result for the S0 power value is not available until the end of the cycle.

www.janitza.de UMG 96-PA

13. 12. 2 Digital outputs

Various functions can be assigned to the three digital outputs:

• Digital output 1

• Digital output 2

• Digital output 3

You can set the digital outputs in the "Periph- ery" area via the conﬁguration window of the GridVis® software:

ATTENTION!

When programming with GridVis®, a selection of energy values that are derived from the power values is received.

- Pulse output for effective energy

- Output for the timer

- ModBus remote output

- Pulse output for reactive energy

- Output for comparator group 1

- Output for the timer

- ModBus remote output

- Output for comparator group 2

- Output for the timer

- ModBus remote output

Pulse output

Digital outputs 1 and 2 can be used for the output of pulses for counting effective energy and apparent energy. For this,a pulse is set at the output after a certain adjustable amount of energy has been reached.

To use a digital output can as a pulse output, you must apply two different settings using the GridVis® Software in the conﬁguration menu:

• Mode for the digital input: S0 output

• Output polarity: Closer, Opener

• Pulse value

Pulse value

With the pulse value, you indicate how much energy (Wh or varh) one pulse should correspond to.

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

If the pulse value is speciﬁed with a:

• positive sign, pulses will only be issued if the measured value also has a positive sign.

• negative sign, pulses will only be issued if the measured value also has a negative sign.

Fig. Conﬁguration of the digital outputs via the Grid-

Vis® software

ATTENTION!

Since the active energy meter works with a return stop, pulses are only issued during import of electrical energy.

ATTENTION!

Since the reactive energy meter works with a return stop, pulses are only issued under inductive load.

UMG 96-PA www.janitza.de

Determine pulse value

1. Set the pulse length according to the requirements of the connected pulse receiver. For a pulse length of e.g. 30 ms, the device can issue a maximum number of 60,000 pulses (see Table "Maximum Pulse Number") per hour.

2. Determining 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 in 3 phases = 45 kW x 3 Maximum connection power = 135 kW

CAUTION!

When using the digital outputs as a pulse output, measurement errors may result from residual ripple.

So use a power adapter whose residual ripple is less than 5% for the supply voltage to the digital inputs and outputs.

Measurement errors in use

3. Calculate the pulse value:

Pulse value =

Maximum connected load

Max. number of pulses/h

In the device, 64 independent weekly timers can be set with:

• a resolution of 1 minute.

• a freely deﬁned active period within one day. The active day within the week can be selected.

Example: 9:25 to 11:45 on Sunday, Monday and Friday

The weekly timers can be conﬁgured as

• tariff converters (1 and 2)

• Set the digital outputs 1 to 3

• as "inoperable

." The status can always be queried via the Modbus. The statuses of the timers are linked via an "OR" operator at the digital output.

The weekly timers can be conﬁgured using the GridVis® software in the "Timer" conﬁguration area)

Output for Modbus remote

Enables switching of the outputs via a Modbus address.

This function can be conﬁgured via the GridVis® software:

• Open the device conﬁguration in GridVis®.

• Set the mode for the digital outputs under "Periphery" to "Modbus remote output."

• Determine the output polarity with:

- Current ﬂow when active (closer)

- Current ﬂow when inactive (opener)

Output for the comparator group

Two comparator groups are available to monitor the thresholds (comparators 1 and

2), each with 3 comparators (A - C).

The results of the comparators A to C can be linked using the "AND" or "OR" operators.

The linkage result from comparator group 1 can be assigned to digital output 2 and the linkage result from comparator group 2 can be assigned to digital output 3.

The comparators can only be conﬁgured using the GridVis® software in the "Compar- ator" conﬁguration area.

Comparator runtime

Comparator runtimes are time counters that create a total for a set comparator output. I.e. if the condition of the comparator is met and the lead time has expired, the counter increases by the respective amount of time the minimum switch-on time is not taken into account here!

Comparator with set threshold violation

• The set threshold is compared to the measurement value.

• If there is a threshold violation for at least the duration of the lead time, a change will be made to the comparator result.

• The result remains for at least the duration of the minimum switch-on time and at the most for the duration of the threshold violation. If there is no longer a threshold violation and the minimum switch-on time has expired, the result is reset.

13. 14 “Drag indicator” function

The “drag indicator” function describes the three highest mean value of a measured values over a deﬁned period of time (time base).

• The calculated mean values can be retrieved via the GridVis® software and via a parameter with a time stamp.

• The period duration (time base), synchronization and capture time can be set in the GridVis® software by using the corresponding parameters.

• The calculation of the mean values is derived from the measurement values of the following value types:

- Current L1

- Current L2

- Current L3

- Effective power L1

- Effective power L2

- Effective power L3

- Effective power, total (L1...L3)

- Apparent power L1

- Apparent power L2

- Apparent power L3

- Apparent power, total (L1...L3)

Capture time:

The individually adjustable Capture time describes a time window in which an incoming pulse triggers a synchronization of the time point. If the device receives a pulse outside of the capture time, the calculated mean values are deleted and the time is reset.

Attention: The setting for the capture time — e.g. in the GridVis® software — describes half of the time window of the entire capture time!

13. 14. 1 Internal synchronization

Period duration (time base):

Individually adjustable period duration in seconds for the calculation of the mean values over this timeframe (duration of the measurement value recording). When an internal synchronization is selected, the mean values are recalculated once the set timeframe has expired.

Synchronization mode:

A synchronization deﬁnes a starting time point for the calculation periods of the mean values. A synchronization is triggered

• by the internal clock (internal synchroniza- tion),

• by setting a parameter (via Modbus) or

• optionally via the digital input 3 (external synchronization)

The means are calculated after the adjustable period duration (time base) has expired. The internal synchronization is performed on the full minute if that describes a multiple of the time base.

13. 14. 2 External synchronization

An external synchronization to calculate the 3 highest mean values can be carried out

• via the digital output 3 (e.g. via a pulse transducer) or

• via a Modbus command

Scenarios of external synchronization:

"No pulse despite setting"
