The UMG604 is intended to be used for the
measurement and calculation of electrical
variables such as voltage, current, energy,
work, harmonic components, etc. in building
installations, at distribution boards, circuit­breakers and busbar trunking systems.
Measuring-circuit voltages and currents must
originate from the same system.

The UMG604 is permanently installed in
control cabinets or small distribution boards.
It can be installed in any position.

The measurement results can be displayed,
stored and read out via serial interfaces and
further processed.

The voltage measurement inputs are designed
for measurements in low-voltage systems in
which rated voltages up to 300 V conductor
to earth and surge voltages of overvoltage
category III can occur.
The current measurement inputs of the
UMG604 are connected via external ../1A or
../5A current transformers.

Measurement in medium and high-voltage
systems takes place with current and voltage
transformers. Special safety requirements
must be complied, which are not dealt with in
any greater detail here.

The UMG604 fulfils the test requirements for
use in industrial areas.

Methods of measurement

The UMG604 measures continuously and
calculates all effective values over a 200 ms
interval.

Operating concept

You can program the UMG604 and call up
measured values in several ways.

• Directly at the device using 2 keys and the
display. You can change the values in the
parameter list (see Appendix) and call up
the measured values from the measured
value displays.

• Via the GridVis programming software.

• In devices with an ethernet interface, via
the homepage of the UMG604.

• Via the RS485 with the modbus protocol.
You can change and call up data with the
help of the modbus address list (is filed on
the enclosed data carrier).

Operation of the UMG604 via the integrated
display and the two keys only is described in
these operating instructions.
The GridVis programming software and the
homepage have their own “online help”.

Short-circuit current transformer con­nections!

The secondary connections of the
current transformer must be short­circuited to them first before the
current supply leads to the UMG604
are disconnected!
If a testing switch is available, which
automatically short circuits the current
transformer's secondary leads, it is
sufficient to place this in the “test”
position, provided the short-circuiters
have been tested first.

Voltage measurement

The UMG604 is designed for the measurement
of alternating voltages in 300 V systems in
which category III overvoltages can occur.
The UMG604 can only determine measured
values if a measurement-current voltage
greater than 10 Veff is applied to at least one
voltage measurement input.

The following must be noted when selecting
the instrument leads for the voltage
measurement:

• The instrument leads required for the
voltage measurement must be suitable
for voltages up to 300 VAC to earth and
520 VAC conductor to conductor.

• Normal instrument leads must be fused by
an overcurrent protective device and routed
via disconnectors.

• Short-circuit proof instrument leads must be
routed via disconnectors only.

Overcurrent protective devices and
disconnectors must be positioned near the
device and must be easy for the user to
reach.

Interfaces

RS232

You can use a RS232 connection cable to
connect the UMG604 to a PC.
The achievable distance between two devices
with RS232 interface depends on the cable
used and the baud rate. The maximum
connectable cable length is 30 m.
As a guideline value, for a transmission rate
of 9600 baud the distance should not exceed
15 m to 30 m.

Shielding

A twisted-conductor and shielded cable must
be provided for connections via the RS232
interface. The shielding at both ends of the
cable must be connected to a large area of the
housing or cabinet parts in order to achieve an
adequate shielding effect.

The permissible ohmic load must be larger
than 3 kohm and the capacitive load caused
by the transmission cable must be smaller
than 2500 pF.

Shields

A twisted, shielded cable is foreseen for con­nections using the RS485 interface.

• Ground the shields of all cables leading to
the cabinet at the cabinet entry point.

• Connect the shield extensively and with
good conductivity with a low external volt­age ground.

• Intercept the cable mechanically above
the ground clip in order to avoid damages
caused by cable movements.

• Use suitable cable insert guides, such
as PG glands, to guide the cable into the
switch cabinet.

Cable type

The cables used must be suitable for an envi­ronmental temperature of at least 80°C.
Recommended cable types:
Unitronic Li2YCY(TP) 2x2x0.22 (Lapp cable)
Unitronic BUS L2/FIP 1x2x0.64 (Lapp cable)

All interfaces can be used simultane­ously.

Bus-Struktur

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

• In a segment, up to 32 participants are
switched together

• The cable is terminated with resistors at the
start and end of a segment.

• For more than 32 participants, repeaters
(line amplifiers) are used to connect the in­dividual segments.

• Devices with terminated resistor have to be
supplied.

• We recommend to install the master UMG
at the end of the segment.

UMG 604

• In case that the master UMG with terminat­ed bus resistor will be removed, the bus is
not under operation.

• In case that slave UMG with terminated bus
resistor will be removed or is not switched
on, the bus can be unstable.

• UMGs which have no termination can be
replaced without any interruption of the
bus.

Digital inputs and outputs

Digital outputs

The UMG604 has 2 transistor switching
outputs. These outputs are metallically
separated from the analysis electronics via
optocouplers.

• The digital outputs can switch direct or
alternating current load.

• The digital outputs can switch loads in­dependant on the polarity of the feeding
voltage.

• The digital outputs are not short-circuit­proof.

• Cables, which are longer but 30m must
be shielded.

which you can connect one transducer.

An input signal is detected at a digital input if a
voltage of at least 10 V and maximum 28 V is
applied. In this case a current of at least 1 mA
and maximum 6 mA flows. Cables longer than
30 m must be laid with shielding.

Putting into Service

Applying the power supply voltage

The power supply voltage level for the UMG604
is given on the rating plate. Supply voltages
which do not correspond to those given on
the rating plate can result in malfunctions and
destruction of the device.

After applying the power supply voltage the
text “Start up” appears in the display. Around
2 - 6 seconds later the UMG604 switches to
the first measured value display.
If no display appears, check whether the
power supply voltage is within the rated
voltage range.

UMG 604

Frequency measurement

For the frequency measurement, the measured
voltage must be greater than 10 V in at least
one voltage measuring path (L-N).
Only detected frequencies within the range
45 Hz to 65 Hz are used for measurement at
the current and voltage measurement inputs.

Power supply voltage

(see rating plate)

43

UMG 604

Applying the measuring-circuit voltage

The UMG604 is suitable for the measurement
of voltages of up to 300 V AC to earth and
520 V AC conductor to conductor.
The UMG604 is not suitable for the
measurement of direct voltages. Voltages
above 300 VAC to earth must be connected
via voltage transformers.

After connecting the measurement-current
voltages, the measured values displayed by
the UMG604 for the L-N and L-L voltages
must correspond to those at the voltage
measurement input.
If a voltage transformer factor is programmed,
this must be taken into account in the
comparison.

Minimum voltage

A measuring-circuit voltage greater than
10 Veff must be applied to at least one of the
voltage measurement inputs. If an adequately
high measuring-circuit voltage is not applied
the UMG604 cannot determine the system
frequency and can therefore also not take a
measurement.

L

At least one phase (L) and the neutral conduc­tor (N) must be connected to the voltage mea­surement input for the measurement.

N

44

UMG 604

Phase sequence

Check the direction of the voltage rotating
field in the measured value display of the
UMG604.
A “right” rotating field usually exists.

Applying the measuring-circuit current

The UMG604 is designed for the connection
of ../1A and ../5A current transformers.
Only alternating currents, not direct currents,
can be measured via the current measurement
inputs.

Short-circuit all current transformer outputs
except one. Compare the currents displayed
by the UMG604 with the applied current.
Taking into account the current transformer
transformation ratio, the current displayed by
the UMG604 must correspond to the input
current.
The UMG604 must display approximately
zero Amperes in the short-circuited current
measurement inputs.

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

45

UMG 604

Checking the energy measurement

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

The UMG604 may only display one power
output in the phase with a non short-circuited
current transformer input. If this is not the case,
check the connection of the measuring-circuit
voltage and the measuring-circuit current.

If the power output amount is correct but the
sign of the power output is negative, S1(k)
and S2(l) could be inverted at the current
transformer or they supply active energy back
into the network.

Configuration

Current transformer ratio

You can assign each of the 4 current
transformer inputs its own current transformer
ratio. A current transformer ratio of 5 A/5 A
is programmed in the factory for all 4 current
transformer inputs.

You can program current transformers with the
same current transformer ratios in addresses
000 and 001. Program current transformers
with different current transformer ratios in
addresses 010 to 041.

A change in current transformer values in
address 000 or 001 overwrites the contents
of addresses 010 to 041 with the current
transformer values from addresses 000 and

001.

A change in current transformer values in
one of the addresses 010 to 041 deletes the
current transformer values in addresses 000
and 001.
