UMG 96RM-E
Product description
Proper use
The UMG 96RM-E is intended for the measurement
and calculation of electrical parameters such as voltage,
current, power, energy, harmonics etc. in building
installations, on distribution units, circuit breakers
and busbar trunking systems.
The UMG 96RM-E is suitable for integration into fixed
and weatherproof switch panels. Conductive switch
panels must be earthed.
Measured voltage and measured current must derive
from the same network.
The measurement results can be displayed and can
be read out and further processed via the RS485
interface.
The voltage measurement inputs are designed for
measurements in low voltage networks, in which rated
voltages of up to 300V relative to earth and surges
in overvoltage category III can occur.
The current measurement inputs I1–I4 of the UMG 96RME are connected via external ../1A or ../5A current
transformers.
8
By continuously monitoring the residual currents
(RCM) of an electrical system via the inputs I5 and I6,
warning pulses can be triggered if a response threshold
is exceeded. Using these, the system operator can
be alarmed before a protective equipment reacts.
The UMG 96RM-E does not provide protection against
and electric shock!
The residual current measuring is done via the current
measurement inputs I5 and I6 via an external residual
current transformer with a rated current of 30 mA.
Measurements in medium and high-voltage networks
is always done via current and voltage transformers.
m
The residual current measuring monitors
residual currents via external current
transformers and can trigger a warning
impule when a response threshold
is exceeded. Thus, the device is NOT
an independent protective device!
UMG 96RM-E
The UMG 96RM-E can be used in industrial and domestic
settings.

UMG 96RM-E
Current measurement via I1 to I4
The UMG 96 RM-E is designed to have current
transformers with secondary currents from ../1A
and ../5A attached cia terminals I1-I4. The factory
default for the current transformer ratio is 5/5A and must
be adapted to the current transformer employed
if necessary.
Direct measurement without a current transformer is not
possible using the UMG 96RM-E.
Only AC currents can be measured - DC currents
cannot.
Via the current measurement input I4 only an apparent
current measurement is carried out thanks to the lack
of a multiplier. Power measurements are therefore not
possible using the I4 input.

UMG 96RM-E
Current direction
The current direction can be individually corrected via
the existing serial interface or on the device for each
phase.
If incorrectly connected, a subsequent re-connection of
the current transformer is not required.
When residual current measurements (RCM) are being
carried out, there is no direction sensitive difference in
the residual currents on the network or load side (not
directionally sensitive).
c
24
Current transformer connections!
The secondary connection of the current
transformer must be short-circuited on this
before the current feed to the UMG 96RME is disconnected!
If a test switch, which automatically shortcircuits the secondary wires of the current
transformer, is available then it is sufficient
to set this to the "Test" position insofar
as the short-circuiting device has been
checked beforehand.
c
c
c
Caution!
A residual current measurement is done
using the terminals I5 and I6 (see page 30).
There is no directional sensitivity of the
residual currents on the network or load
sides (not directionally sensitive).
Earthing of current transformers!
If a connection is provided for the earthing
of secondary windings then this must be
connected to the earth.
Open-circuit current transformers!
High voltage spikes that are dangerous
to touch can occur on current transformers
that are driven with open-circuit secondary
windings!
With "safe open-circuit current
transformers" the winding insulation
is rated such that the current transformer
can be driven open. However, even these
current transformers are dangerous
to touch when they are driven open-circuit.

UMG 96RM-E
Analog inputs
The UMG 96RM-E has 2 analog inputs which can
be used for one residual current measurement or one
temperature measurement. The measurement is done
using terminals 32-34 (input 1) or 35-37 (input 2).
The analog inputs can be used for residual current
or temperature measurement in accordance with
the following table:
Measurement
Terminal
Temperature
32/34 (input 1) and
35/37 (input 2)
Residual current
32/33/34 (input 1) and
35/36/37 (input 2)
30
c
Attention!
Operating equipment connected to the
analogue inputs must exhibit reinforced
or double insulation from mains supply
circuits!
Example - temperature sensor:
A temperature sensor in close proximity to non-isolated
mains cables should measure within a 300V CAT III
network.
Remedy:
The temperature sensor must be equipped with
reinforced or double insulation for 300V CAT III. This
equates to a test voltage for the temperature sensor of
3000V AC (duration 1 min.).
Example - residual current transformer:
A residual current transformer should measure on
isolated mains cables within a 300V CAT III network.
Remedy:
The insulation of the mains cables and the insulation
of the residual current transformer must fulfil the basic
insulation requirements for 300V CAT III. This equates
to a test voltage of 1500V 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.
UMG 96RM-E
Residual current measurement (RCM) via I5, I6

The cable used must be suitable for an environmental
temperature of at least 80°C.
• Earth the screens of all cables that lead to the cabinet,
upon entering the cabinet.
• Connect the screens over a generous area
and in a manner that will conduct well, to a low-noise
earth.
• Gather the cables mechanically above the earthing
clamp in order to avoid damage due to cable
movements.
• Use suitable cable glands to feed the cables into
the cabinet - for example armoured conduit couplings.

Bus structure
• All devices are connected in a bus structure (line)
and 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
120Ohm, 1/4W) 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.
• 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.

determined for most measured values.
The min. value is the smallest measured value determined
since the last deletion. The max. value is the highest
measured value determined since the last deletion.
All minimum and maximum values are compared with
the corresponding measured values and overwritten
when exceeded or fallen short of.
The minimum and maximum values are saved every
5 minutes in an EEPROM without date and time. Thus,
the minimum and maximum values of the past 5 minutes
may be lost due to an operating voltage failure.

Phase sequence
LCD contrast (Addr. 035)
The voltage phase sequence and the phase L1 frequency
are displayed on the screen.
The preferred view for the LCD display is from "below".
The LCD display contrast can be adapted by the user.
The contrast can be set stepwise in the range from
0 to 9.
The phase sequence shows the three-phase system
sequence. The rotary field usually rotates to the "right".
The voltage measurement input phase sequence
is checked and displayed in the UMG 96RM-E.
If the string moves in a clockwise direction, this means
that the rotary field rotates to the "right"; if the string
moves in a counter-clockwise direction, this means that
the rotary field rotates to the "left".
The field rotation can only be determined when
the measurement and operating voltage inputs are fully
connected. If a phase is missing or two equal phases are
connected, then the phase sequence is not determined
and the string is not moving.

UMG 96RM-E
Putting into service
Applying the measuring-circuit current
Connecting the supply voltage
The UMG 96RM-E is designed for the connection
of .. /1A and .. /5A current transformers.
Only AC currents can be measured via the current
measurement inputs - DC currents cannot.
Short circuit all current transformer outputs except for
one. Compare the currents displayed by the UMG 96RM
with the applied current.
Bearing in mind the current transformer conversion
ratio, the current displayed by the UMG 96RM-E must
correspond with the input current.
The UMG 96RM-E must display approx. zero amperes
in the short-circuited current measurement inputs.
The current transformer ratio is factory set to 5/5A
and must be adapted to the current transformer used
if necessary.
• The power supply voltage level for the UMG 96RM-E
is given on the rating plate.
• After applying the power supply voltage the device
switches on to display the first measured value.
• If no display appears, check whether the power supply
voltage is within the rated voltage range.
Applying the measuring-circuit voltage
• Measurement of voltages in the mains with over
300VAC to earth must be connected via voltage
transformers.
• After connecting the measurement-current voltages,
the measured values displayed by the UMG 96RM-E
for the L-N and L-L voltages must correspond to those
at the voltage measurement input.

Caution!
Voltages and currents that are outside
the permissible measuring range can lead
to personal injury and damage the device.
m
m
Caution!
If the supply voltage does not correspond
to the voltage indicated on the rating
plate, this may lead to malfunctions severe
damage to the device.
Caution!
The UMG 96RM is not suitable for
measuring DC voltages.
69
UMG 96RM-E
Phase sequence
Applying the residual current
Check the direction of the voltage rotating field
in the measured value display of the UMG 96RM‑E.
A “right” rotating field usually exists.
Connect residual current transformer only to the I5
and I6 inputs with a rated current of 30mA! Both residual
current inputs can measure AC currents, pulsing direct
currents and DC currents.
Check phase assignment
The assignment of the outer conductors to the current
transformer is correct, if a current transformer is short
circuited on the secondary, and the current indicated
by the UMG 96RM-E drops to 0A in the corresponding
phase.
Bearing in mind the current transformer conversion ratio,
the residual current displayed by the UMG96RM-E must
correspond with the input current.
The current transformer ratio is factory set to 5/5A
and must be adapted to the residual current transformer
used if necessary.
Checking the energy measurement
Short-circuit all current transformer outputs except for
one and check the displayed power outputs.
The UMG 96RM-E 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 measuringcircuit current.
C
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.
C
70
The UMG 96RM-E requires the mains
frequency to measure the residual
current. For this purpose, the measuringcircuit voltage should be applied or a
fixed frequency should be set.
It is not necessary to configure a
connection schematic for residual current
inputs I5 and I6.
UMG 96RM-E
Failure monitoring (RCM) for I5, I6
The UMG96RM-E enables continuous monitoring of the
connection to the residual current transformer on inputs
I5 and I6.
Activation of failure monitoring is performed by setting
address 21264 for the residual-current measurement
input I5 and 21265 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:

Checking the measurement
Checking the total power outputs
If all voltage and current inputs are correctly connected,
the individual and cumulative outputs are computed
and displayed correctly.
If all voltages, currents and outputs for the respective
outer conductors are correctly displayed, the total
power outputs measured by the UMG 96RM must also
be correct. To confirm this, the total outputs measured
by the UMG 96RM should be compared with the work
of the active and reactive power meters located
in the incoming supply.
Checking the individual outputs
In case that a current transformer is assigned
to the wrong outer conductor, the corresponding power
output will be measured and indicated incorrectly.
The
assignment
of
the
outer
conductor
and the UMG 96RM-E current transformer is correct,
if no voltage is measured between the outer conductor
and the corresponding current transformer (primary).
In order to ensure that an outer conductor at the voltage
measurement input is assigned to the correct current
transformer, the respective current transformer can
be short-circuited on the secondary side. The apparent
power displayed by the UMG 96RM-E must then
be approx. zero in this phase.
If the apparent power is correctly displayed but the
active power is displayed with a „-“ sign, then the current
transformer terminals are reversed or power is supplied
to the power supply company.

UMG 96RM-E
Impulse 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 need to make various adjustments in the software
GridVis (configuration menu) to use a digital output as
a pulse one.
• Digital output,
• Selection of source,
• Selection of measured value,
• Pulse length,
• Pulse value.

Pulse length
The pulse length applies to both pulse outputs and is set
by the software GridVis.
The typical pulse length of S0 pulse 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.

UMG 96RM-E
Pulse value
The pulse value is used to indicate how much energy
(Wh or varh) should correspond to a pulse.
The pulse value is determined by the maximum
connected load and the maximum number of pulses per
hour.
If you check the pulse value with a positive sign,
the pulses will only be emitted when the measured value
has a positive sign.
If you check the pulse value with a negative sign,
the pulses will only be produced when the measured
value has a negative sign.

Comparators and monitoring threshold values
Five comparator groups (1-5) and 10 comparators per
group (A – J) can be selected in order to monitor/control
the thresholds. The results of the comparators A to J can
be linked with AND or OR operators
The result of the AND and OR operator can be allocated
to the respective digital output.
The function “display blinking” can be additionally
assigned to every comparator group. The effect is the
change of the display backlight between maximum and
minimum brightness when the comparator output is
active.
Fig.: Software GridVis, configuration menu

UMG 96RM-E
Comparator running times
Comparator running times are time counters, which
are added together at a set comparator output. i.e.
if the condition of the comparator is fulfilled and the
lead time has elapsed, the counter is increased by
the corresponding amount of time - this does not take
account of the min. switch-on time!
Comparator with set limit value violation
• The set limit value is compared to the measured value.
• If the limit value violation occurs for at least the
duration of the lead time, the comparator result is
changed.
• The result is retained for at least the duration of
the min. switch-on time and for no longer than the
duration of the limit value violation. If there is no longer
a limit value violation and the min. switch-on time has
elapsed, the result is reset.
