7. 5 Measured voltage

The device has 4 voltage measurement

inputs (V1 to V4) that are located on the rear

of the device.

• V1 to V3 for the baseline measurement.

• V4 for the supporting measurement

The connections are called supporting

and baseline measurement below.

7. 5. 1 Overvoltage

The voltage measurement inputs are suitable for

measurements in networks where overvoltages

of category 600 V CAT III can occur.

7. 5. 2 Frequency

The device:

• is suitable for measurements in networks

in which the fundamental oscillation

of the voltage is in the range of 40 Hz

to 70 Hz.

• only measures the frequency on

measurement inputs V1, V2 and V3.

WARNING!

Risk of injury due

to electric voltage!

Severe bodily injuries or death can occur

due to a failure to observe the connection

conditions for the voltage measurement

inputs.

Therefore, note the following:

• Do not use the device for voltage

measurement in SELV circuits

(safe extra low voltage).

• Connect the voltages higher than

the permitted network rated voltages

using voltage transformers.

• The voltage measurement inputs

on the device are dangerous

if touched!

• Install a disconnector as described

in “7. 3 Disconnectors”.

• Use a UL/IEC-approved overcurrent

protection with a rated value, which

is suitable for the short circuit current

at the connection point.

CAUTION!

Malfunction due

to incorrect connection

If the device is connected incorrectly,

incorrect measured values may be returned.

Therefore, note the following:

• Measured voltages and currents must

derive from the same network.

• The device is not suitable

for measuring DC voltage.

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.

WARNING!

Risk of injury due

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 screw-

type 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.

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

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)”.

CNOTE!

The transformation ratios for the

residual current transformer inputs

can be congured via the GridVis®

software. (see www.janitza.com)

CAUTION!

Risk of injury due to

high voltage

Insufcient insulation of the operating equip-

ment on the analogue inputs (temperature

measurement and residual current monitor-

ing) 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!

7. 8. 2 Example: Residual current trans-

former insulation

A residual current transformer should meas-

ure 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 full 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.

CAUTION!

Transmission errors and

damage to property due to

electrical faults

If the line is longer than 30 m, there is an

increased probability of transmission errors

and damage to the device due to atmos-

pheric discharge.

Use a shielded cable for connection to

the residual current transformer.

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. c

WARNING!

Risk of injury due

to electric voltage!

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.

CAUTION!

Damage to property

due to not observing

the connection conditions

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.

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.

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:

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

Fig. Phasor diagram

Current (shown with a short

phasor)

Voltage (shown with a long

phasor)

CNOTE!

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

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.

Factory pre-conﬁgured Proﬁbus proﬁles

cannot be subsequently changed.

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

interface in the device.

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 variables

1) 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.

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.

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:

• 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®.

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

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 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.

CNOTE!

The pulse interval is proportional

to the power output within

the selected settings.

CNOTE!

When programming with GridVis®,

you receive a selection of work

values which are derived from

the power output values.

(see www.janitza.de)

CNOTE!

Since the effective energy meter

operates with a backstop, pulses

will only be generated when

drawing electricity.

CNOTE!

Since the reactive energy meter

operates with a backstop, pulses

will only be generated with inductive

load applied.

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]

Pulse value = 135 kW / 60000 Imp/h

Pulse value = 0.00225 pulses/kWh

Pulse value = 2.25 pulses/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.
