Overcurrent protection device for the line
protection of the supply voltage

Recommendation for the overcurrent protection
device for line protection of the supply voltage
(depending on the device versions):

· 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 circuit breaker depending on the
versions:

· 230 V option:
For a B6A circuit breaker, a maximum of
4 devices.
For a B16A circuit breaker, a maximum of
11 devices.

· 24 V option:
For a B6A circuit breaker, a maximum of
3 devices.
For a B16A circuit breaker, a maximum of
9 devices.

NOTE

The fuse is only a line protection - is not device
protection!

7.4 Voltage measurement

The device has 3 voltage measurement inputs
(V1 to V3) that are on the rear side of the device.

7.4.1 Overvoltage

The voltage measurement inputs are suitable for
measuring in networks in which category 600 V
CAT III overvoltages can occur (rated surge
voltage 6 kV).

7.4.2 Frequency

The device:

· requires the power frequency for the
measurement and calculation of measured
values.

· is suitable for measuring in networks in which
the power frequency of the voltage is in the
45 Hz to 65 Hz range.

The power frequency is calculated using the
phase L1 measured voltage. The sampling
frequency of the voltage and current
measurement inputs is calculated based on the
power frequency.

The frequency of the voltage power frequency
can no longer be calculated accurately while
measuring with severe voltage distortion. What
this means is that a fixed value should be
specified for the corresponding power frequency
for measured voltages with severe voltage
distortion. Voltage distortions occur, for example,
when measuring consumers that are operated
with a phase angle control. Current distortions do
not have an impact on the determined frequency.

NOTE

The MID device only supports an automatic
frequency calculation (45 -65 Hz)!

The device:

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

· is only approved for a current measurement
using the current transformer.

· does not measure DC currents.

The default current transformer ratio is set
to 5/5 A and may need to be adjusted to the
current transformer used.

WARNING

Risk of injury due to electric voltage on
current transformers!

High voltage spikes that are dangerous to
touch can arise on current transformers that are
operated open on the secondary side, which
can result in serious injuries or even death.

Therefore, please observe the following:

· Before starting work, disconnect your

system from the power supply! Verify that
there is no current!

· Avoid open operation of the current

transformer.

· Short-circuit the unloaded current

transformer.

· Before interrupting the power supply, it

is critical to short circuit the secondary
connections of the current transformer.

· If a test switch is present that automatically

short circuits the secondary lines of the
current transformer, it is sufficient to
put it in the “test” position provided that
the short-circuiters have been checked
beforehand.

· Only use current transformers that have

a basic insulation according to
IEC 61010-1:2010.

· Fasten the attached screw-type terminal to

the device with the two screws.

· Even safe open current transformers are

dangerous to touch if they are operated open.

· Observe the documentation for the current

transformers!

WARNING

Risk of injury due to electric voltage!

During high measured currents, temperatures
up to 80 °C can arise at the connections.

Use lines which are designed for an operat­ing temperature of at least 80 °C.

WARNING

Risk of injury due to electric voltage!

Serious personal injuries or death can occur
due to:

· Touching live exposed or stripped cores.

· Device inputs that are dangerous to touch.

De-energize your system before beginning
to work! Check that there is no voltage!
Ground the system!

7.5.1 Current direction

You can correct the current direction for each
phase individually using the existing serial
interfaces. So, there is no need to subsequently
reconnect the current transformer in the event of
an improper connection.

7.5.2 Summation current measurement

For a summation current measurement via
two current transformers, first set their total
transformation ratio on the device. A description
of how to set the current transformer ratios is
provided in chapter 12.3.2 on page 36.

Example:

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

The device must then be set as follows:
Primary current: 1000 A + 1000 A = 2000 A
Secondary current: 5 A

13.2 Measured voltage

Voltage measurements in lines with rated voltage
exceeding the maximum specified rated voltage
(see chapter 6.2 “Rated voltages”) must be
connected using voltage transformers.

Connect the measured voltage:

1. Connect the measured voltage with a terminal
on the rear of the device.

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

3. You may need to account for the set voltage
transformer factors.

NOTE

Before commissioning, delete possible
production-related contents of the energy
meter, the min./max. Values and recordings.

CAUTION

Property damage due to noncompliance
with the connection conditions.

Noncompliance of the connection conditions
can damage or destroy your device.

Therefore, please observe the following:

· Observe the specifications on the

nameplate relating to voltage and
frequency.

· Do not use the device to measure DC

current.

WARNING

Risk of injury due to electric voltage!

If the device is subject to impulse voltages
exceeding the permissible overvoltage
category, safety-relevant insulations in the
device may suffer damage. As a result,
the safety of the product can no longer be
guaranteed.

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

13.3 Measured current

The device:

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

· does not measure DC currents.

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

The default current transformer ratio is set to
5/5 A and may need to be adjusted to the current
transformer used.

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

2. Compare the current displayed on the device
with the applied input current.

- The currents must match allowing for the
current transformer transformation ratio.

- The device must display approx. 0 amperes
in the short circuited current measurement
inputs.

13.5 Frequency

The device requires the rated or power frequency
to measure and calculate measured values,
which can either be specified by the user or
automatically determined by the device.

NOTE

The UMG 96-PA

MID

only supports automatic

frequency calculation (45 -65 Hz)!

· To determine power frequency, a voltage
greater than 20 Veff (4-conductor measurement)
or a voltage L1-L2 greater than 34 Veff
(3-conductor measurement) must be present at
voltage measurement input V1.

· The power frequency must be within the range
of 45 to 65 Hz.

· If the applied voltage is not sufficiently high, the
device will be unable to determine the power
frequency and thus will also not be able to
conduct a measurement.

13.5.1 Principles of the pointer diagram

The pointer diagram provides a graphic
description of the phase shift or the phase angle
between voltage and current. The pointers rotate
with a consistent angle speed - proportionate to
the frequency of voltage and current - around an
original source. Thus, the pointer diagram shows
the current state of the variables in an AC circuit.

13.7 Checking the power measurement

Short circuit all current transformer outputs
except for one and verify the powers displayed.

· The device may only display one power in the
phase with the current transformer output that
is not short circuited.

· If this is not the case, verify the connections
of the measured voltage and the measured
current.

If the value of the active power is correct, but the
sign is negative, this can have two causes:

1. Reversed connections S1(k) and S2(l) on the
current transformer, or

2. Active energy is being fed back into the
network.

13.10 Harmonics

Harmonics are caused, for example, by operating
resources with a non-linear characteristic curve.
The additional frequencies represent the integer
multiple of a fundamental oscillation and show
how the operating resources affect the power
grid. Potential effects of harmonics are, for
example:

· Operating resources heat up even more

· Additional current on the neutral conductor

· An overload and a reduced service life of
electric consumers

Harmonic loads are the main cause for invisible
voltage quality problems which involve huge
costs for repairs and require an additional
investment to replace defective devices.

The device measures harmonics of the voltage
in the range of 45 to 65 Hz. The calculated
harmonics of the voltages and currents relate to
this power frequency.

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

13.12 Digital Inputs/Outputs

You device has 3 digital outputs and three digital
inputs.

· You configure the digital inputs and outputs
using the GridVis® software.

· You can download the GridVis® software from
our website (www.janitza.de).

NOTE

The UMG 96-PA

MID

features limited digital

output configuration!

13.12.1 Digital inputs

From the digital inputs, you send information
from other devices that have a digital output
directly to your device.
In addition, there is also an option to configure
digital inputs as functional inputs (function
mode). As a functional input, each digital input
has its own function. A functional input cannot
be configured as a pulse counter.

From the configuration window of the GridVis®
software, you can configure digital inputs from
the “Peripherals” area:

Function mode

· Function assigned to the digital input.

Pulse counter

· Value type of the arriving signal (such as electric
power, gas/water consumption, CO2,...)

· Pulse value for measurement or power values.

· Length of the averaging time.

The states of the digital inputs are each stored
on their own Modbus address.
For each digital input, the last
16 switching activities (incidents) are logged with
a time stamp.

Fig. Configuring the digital inputs using the GridVis®

software

Function mode

Each digital input can be assigned a specific
function.

· Digital input 1
Configuration possible as a tariff switch (HT/NT).

· Digital input 2
Configuration to synchronize the device clock
with the option to synchronize to the minute or
to the hour.
The device can also be synchronized from
a Modbus address.

· Digital input 3
Configuration as a reset input for synchronous
value of the trailer pointing function. The trailer
pointer can also be synchronized from the
Modbus address.

Pulse counter

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

Due to the minimum pulse duration and the
minimum pulse pause, the result is a maximum
number of pulses per hour as follows:

Pulse length

(Pulse

duration)

Pulse pause

(Pulse

Max. pulses/h

20 ms 20 ms 90 000 pulse/h

30 ms 30 ms 60 000 pulse/h

36 000 pulse/h

100 ms 100 ms 18 000 pulse/h

500 ms 500 ms 3 600 pulse/h

1 s 1 s 1 800 pulse/h

10 s 10 s 180 pulse/h

The pulse counters can be configured with
a simultaneous measured value or power
calculation. The pulses are counted as a 64 bit
number and during continuous operation (25 Hz)
spill over after approx. 1.17 x 10 10 years.

Pulse value

Each digital input can be assigned a pulse value.
With the pulse value you specify which measured
value or power value (such as energy) should
correspond to a pulse.

Measured values calculation:

Measured value = pulse x pulse value

Power value calculation:

Power value =

pulse x pulse value

Time [s]

Because the pulse interval can be quite large,
there is an option to continuously calculate the
measure or power values. For this reason, only
average values are calculated. The calculation
of the average values results from the average
value calculation from the number of pulses per
period multiplied by the pulse value. To calculate
the average power values, divide this value by
a configurable time value.

The period is assigned to the digital input and
can be configured in the range between 1 to
60 minutes. After the period has expired, the
value can be called up via Modbus.

An external synchronization can be switched
for each digital input, whereas one sync pulse
completes one period and starts a new one.
A capture time of 30 seconds is predefined
as a set value for external synchronization.
If no sync pulse is available after the period
has expired, the system waits a maximum
of 30 seconds and is then synchronized by
the software. All additional periods are then
synchronized by the software.

NOTE

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

NOTE

During the programming with the GridVis®
software, you will receive a selection of energy
values which are derived from the power values.

per hour.

13.12.2 Digital outputs

Different functions can be assigned to the three
digital outputs:

· Digital output 11)

- Pulse output for active energy

- Output for timer

- Modbus remote output

· Digital output 2

- Pulse output for reactive energy

- Output for comparator group 1

- Output for timer

- Modbus remote output

· Digital output 3

- Output for comparator group 2

- Output for timer

- Modbus remote output

From the configuration window of the GridVis®
software, you can configure digital outputs from
the “Peripherals” area:

Pulse output

Digital output 11) and 2 can be used for the
output of pulses for counting active energy and
reactive energy. For this purpose, a pulse is
applied at the output after a certain configurable
energy quantity is reached.

NOTE

1)

The function MID active energy is dedicated

to digital output 1 of the UMG 96-PA

MID

.

In order to use a digital output as a pulse output,
you must make various settings using the
GridVis® software within the configuration menu:

· Pulse width

· Modbus for digital input: S0 output

· Output polarity: NO, NC

· Pulse value

NOTE

Since the active energy meter works with
a non-return device, pulses are only output
during consumption of electrical energy.

Since the reactive energy meter works with
a non-return device, pulses are only output
during an inductive load.

Determining the pulse value

1. Establish the pulse length according to the
requirements of the connected pulse receiver.
With a pulse length of e.g. 30 ms, the device
can emit a maximum number of 60,000 pulses
per hour (see table “Maximum number of
pulses”).

2. Calculate 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 with 3 phases = 45 kW x 3
Max. connected load = 135 kW

NOTE

The default setting for the pulse duration is 30 ms
for the MID device and cannot be adjusted!

Pulse value

The pulse value specifies how much energy (Wh
or varh) a pulse should correspond to.

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

If you specify a pulse value with a:
positive sign, pulses are only output if the
measured value also has a positive sign.

· negative sign, pulses are only output if the
measured value also has a negative sign.

Comparator durations are time counters that add
up for a set comparator output. That is, if the
condition of the comparator has been met and
the lead time has expired, the counter increases
by the relevant time amount - the minimum
switching time is not considered here!

Comparator with set limit violation

· The set limit value is compared with the
measured value.

· If a limit value violation is active at least for the
duration of the lead time, the comparative result
is changed.

· The result remains unchanged at least for the
duration of the minimum switch-on time and no
more than for the duration of the limit violation.
The result is reset once there is no more limit
violation and the minimum switch-on time has

13.14 “Trailer pointer” function

The “trailer pointer” function describes the
three highest average values of value types via
a defined period duration (time base).

· The calculated average values can be called up
via the GridVis® software and via a parameter
with time stamp.

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

· The average value is calculated using the
measured values of the following value types:

- Current L1

- Current L2

- Current L3

- Active power L1

- Active power L2

- Active power L3

- Total active power (L1...L3)

- Apparent power L1

- Apparent power L2

- Apparent power L3

- Total apparent power (L1...L3)

Period duration (time base):

Period duration that can be set individually
in seconds for calculating the average values
throughout this period (duration of the
measured value recording). When an internal
synchronization is selected, the average values
are recalculated after the set period of time has
expired.

Synchronization mode:

A synchronization determines a start time for the
calculation periods of the average values. Here,
synchronization is triggered

· By the internal clock (internal synchronization);

· By setting a parameter (via Modbus); or

· Optionally via the digital input 3 (external

synchronization).

Capture time:

The Capture time that can be set individually
describes a time window in which an incoming
pulse performs a synchronization of the time.
If the device receives a pulse outside of the
capture time, the calculated average values are
deleted and the time is reset.

Note: The capture time setting - for example in
the GridVis® software — describes half the time
window of the entire capture time!

13.14.1 Internal synchronization

The average values are calculated after the
configurable period duration (time base) has
expired. The internal synchronization occurs at
the full minute if it describes a multiple of the
time base.

NOTE

To perform an internal synchronization, the
options Synchronization via Modbus AND
Synchronization via the digital output 3 must be
disabled!

13.14.2 External synchronization

An external synchronization for calculating the
three highest values is performed

· Via digital input 3 (e.g. via a pulse generator), or

· Via a Modbus command

External synchronization scenarios:

“No pulse despite setting”

If no pulse is emitted via digital input 3 or
a Modbus command, the measured values
are stored as they would be for an internal
synchronization, however not just to the full
minute!

“A pulse”

If the device receives a pulse once or a Modbus
command outside of the capture time, the
number of measured values summed up until
then is reset to calculate the average value and
the time. The time is newly defined as a relative
zero point and a new calculation is performed!

Example:

The power increases while time progresses. With
the pulse (09:06:47 AM) outside of the capture
time, the values are reset to 0. From this time on,
a new summation of intermediate values starts.
Because no more pulse arrives, the average
value is calculated based on the set time (time
base).

“Periodic pulse”

Several scenarios apply if the device receives
periodic pulses via the digital input 3 or periodic
Modbus commands.

Scenario “Pulse outside of the capture time”:

· Summed intermediate values are set to 0.
