UMG 96RM-EL

Current measurement

The UMG 96RM-EL is designed for connecting cur­rent transformers with secondary currents of ../1A and
../5A. The factory set current transformer ratio is 5/5 A
and may need to be adapted to the current transform­ers.
It is not possible to perform a direct measurement with­out a current transformer with the UMG 96RM-EL.
Only AC currents (and not DC currents) can be meas­ured.

Earthing of current transformers!

If a connection is provided for the earthing
of secondary windings then this must
be connected to the earth.

Attention!

The UMG 96RM-EL is not suitable for the
measurement of DC voltages.

Attention!

The current measurement inputs are
dangerous to touch.

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.

If a connection is provided for the earthing
of secondary windings then this must be

c

Current transformer connections!

The secondary connection of the current
transformer must be short-circuited on this
before the current feed to the UMG 96RM­EL 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

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-EL

Parameters and measured values

All parameters necessary for operating the
UMG 96RM-EL, e.g. the current transformer data, and
a selection of frequently required measured values are
stored in the table.
The contents of most addresses can be accessed via the
serial interface and the buttons on the UMG 96RM-EL.

Only the first 3 significant digits of a value can be entered
on the device. Values with more digits can be entered
using GridVis.
The device always only displays the first 3 significant
digits of a value.

Selected measured values are summarised in measured
value display profiles and can be shown in display mode
using buttons 1 and 2.

The current measured value display profile and the
current display change profile can only be read and
changed via the Ethernet interface.

32

Example of the parameter display

On the UMG 96RM-EL
display the value “006” is
shown as the content of ad­dress “036”. This parameter
reflects the brightness of
the backlighting (0=dark, 9=
bright).

Example of the measured
value display

In this example, the UMG 96
RM-EL display shows the volt­ages L to N with 230 V each.

Configuration

Applying the supply voltage

To configure the UMG 96RM-EL, the supply voltage
must be connected.

The level of supply voltage for the UMG 96RM-EL can
be found on the nameplate.

If no display appears, check the operating voltage
to determine whether it is within the rated voltage range.

Current and voltage transformers

A current transformer is set to 5/5 A in the factory.
The pre-programmed voltage transformer ratio only
needs to be changed if voltage transformers are
connected.

When connecting voltage transformers, the measure­ment voltage on the UMG 96RM-EL nameplate must be
observed!

Attention!

Supply voltages that do not correspond
to the nameplate information can lead
to device malfunction or destruction.

The adjustable value 0 for the primary
current transformer does not produce
any useful energy values and must not
be used.

Devices, which are programmed to au­tomatic frequency detection, need ap­proximately 20 seconds to detect grid
frequency. During this period, the meas­ured values do not keep the confirmed
measuring accuracy.

Dynamic IP allocation (dyn)
The dynamic allocation of the TCP / IP settings (device/
gateway address and subnet mask) provides for a fully
automated integration of the device into an existing net­work with a DHCP server. TCP / IP settings do not need
to be configured manually as they are automatically as­signed by the DHCP server when the device is started.

Min. and max. values

All measured values are measured and calculated dur­ing all 10/12 periods. Minimum and maximum values are
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.

Delete min. and max. values (Addr.506)

If "001" is set for address 506, all minimum and maxi­mum values can be deleted simultaneously.
One exception is the maximum value of the mean cur­rent. Press and hold button 2 to delete the maximum
value of the mean current in the display menu.

Mains frequency (Addr. 034)

UMG 96RM-EL

For automatic ascertainment of the mains frequency, an
L1-N voltage larger than 10Veff must be applied to the
voltage measurement input V1.

The sampling frequency is computed for the current
and voltage inputs based on the mains frequency.

If the test voltage is missing, neither the network nor
the sampling frequency can be computed. An acknowl­edgeable error message "500" will be displayed.
Voltage, current and all resulting values are calculated
and displayed based on the most recent frequen­cy measurement and/or possible power couplings.
The measured values that have been determined can
no longer guarantee the declared precision.

When another measurement of frequency can be car­ried out, the error message will automatically disappear
in about 5 seconds after the voltage returns.

The error is not displayed when a fixed frequency is set.

Setting range: 0, 45 .. 65

0 = automatic frequency determination.
The mains frequency is determined based
on the measurement voltage.

Measured value relay

All measured values are calculated every nine periods
and can be recalled once per second on the measured
value displays. Two methods are available for retrieving
the measured value displays:

• The automatically changing display of selected
measured values, referred to here as measured value
relaying.

• Selection of a measured value display using buttons
1 and 2 from a preselected display profile.

Both methods are simultaneously available. Measured
value relaying is active if at least one measured value
display is programmed with a changeover time greater
than 0 seconds.
If a button is pressed, the measured value displays
of the selected display profile can be browsed. If no
button is pressed for about 60 seconds, the device
switches to the measured value relay and the measured
values from the selected display change profile
of the programmed measured value displays are shown
one after the other.

Changeover time (addr. 039)

Adjustment range: 0 .. 60 seconds
If 0 seconds are set, no changeover takes place between
the measured value displays selected for the measured
value relay.
The changeover time applies for all display change
profiles.

Measured value displays

After return of the power supply, the UMG 96RM-EL
shows the first measured value panel from the current
display profile. In order to keep the selection of meas­ured values to be displayed arranged in a clear manner,
only one part of the available measured values is pre­programmed for recall in the measured value display by
default. A different display profile can be selected if other
measured values are required to be shown on the UMG
96RM-EL display.

be lost.
To avoid data loss, you should read
and save the measured values before de­letion using the GridVis software.

Phase sequence

The voltage phase sequence and the phase L1 frequen­cy are displayed on the screen.

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-EL. 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.

Operation backlight (addr. 036)
The operation backlight is activated by pushing the ap­propriate button, or with a restart.

Standby backlight (addr. 747)
This backlight is activated after an adjustable period of
time (addr. 746). If no button is pressed within this peri­od, then the device switches to the standby backlight.
If buttons 1 - 3 are pressed, the device switches to
the operation backlight and the defined period of time
begins again.

If the brightness settings for the two backlights are set to
the same value, then no change is discernible between
the operation and standby backlights.

Operating hours meter

The operating hours meter measures the UMG 96RM-EL
recording and displaying time.
The operating period is measured and displayed in hours
with a resolution of 0.1 h. The operating hours meter
cannot be reset.

Overall runtime of comparators

The overall runtime of a comparator is the sum of the run­times exceeding the comparator result limit value.
The total running time of the comparators can only
be reset by the GridVis software. All running times are
reset simultaneously.

UMG 96RM-EL

Commissioning

Applying the supply voltage

• The level of supply voltage for the UMG 96RM-EL can
be found on the nameplate.

• After applying the supply voltage, the UMG 96RM-EL
switches to the first measured value display.

• If no display appears, the supply voltage must
be checked to determine whether it is in the rated
voltage range.

Applying the measured voltage

• Voltage measurements in networks with rated voltages
above 300V AC to ground must be connected to a
voltage transformer.

• After the measured voltages are connected, the
measured values for the L-N and L-L voltages
displayed by the UMG 96RM-EL must match those at
the voltage measurement input.

Attention!

m

Voltages and currents outside the permis­sible metering range can result in personal
injury and damage to the device.

Applying the measured current

The UMG 96RM-EL is designed for connecting ../1 A
and ../5 A current transformers.
Only AC currents and not DC currents can be measured
via the current measurement inputs.
Short circuit all current transformer outputs except
for one. Compare the currents displayed on the UMG
96RM-EL with the applied current.
The current displayed by the UMG 96RM-EL must match
the input current, taking the current transformer ratio into
consideration.
In the short circuit current measurement inputs, the UMG
96RM-EL must show approx. zero amperes.

The factory-set current transformer ratio is 5/5 A and may
need to be adapted to the current transformer used.

Attention!

m

m

Supply voltages that do not correspond
to the nameplate information can lead
to device malfunction or destruction.

Attention!

The UMG 96RM-EL is not suitable for the
measurement of DC voltages.

53

UMG 96RM-EL

Rotation field direction

Check the direction of the voltage rotation field on the
measured value display of the UMG 96RM-EL.
Usually there is a "clockwise" spinning rotation field.

Checking the phase assignment

The assignment of the phase conductor to the current
transformer is correct if a current transformer is short
circuited at the secondary terminals and the current
shown by the UMG 96RM-EL in the corresponding
phase sinks to 0A.

Checking the power measurement

Short circuit all current transformer outputs except for
one and check the displayed power.
The UMG 96RM-EL must only show one rating in the
phase with the non-short-circuited current transformer
input. If this does not apply, check the measured voltage
connection and the measured current connection.

If the magnitude of the real power is correct but the sign
of the real power is negative, this can be due to two
causes:

• The connections S1 (k) and S2 (I) on the current
transformer are inverted.

• Active energy is being returned to the network.

54

Checking the measurement

If all voltage and current measurement inputs are
correctly connected, the individual and sum power
ratings are accurately calculated and displayed.

Checking the individual power ratings

If the current transformer is assigned to the wrong
phase conductor, the associated power rating will be
incorrectly measured and displayed.
The assignment of the phase conductor to the current
transformer on the UMG 96RM-EL is correct if there
is no voltage between the phase conductor and the
associated current transformer (primary).
In order to ensure that a phase conductor on the voltage
measurement input is assigned to the correct current
transformer, the respective current transformer can be
short-circuited at the secondary terminals. The apparent
power shown by the UMG 96RM-EL must then be zero
in this phase.
If the apparent power is correctly displayed but the real
power is shown with a "-" sign, the current transformer
terminals are inverted or power is being fed to the power
company.

UMG 96RM-EL

Check the sum power ratings

If all voltages, currents and power ratings for the
respective phase conductor are correctly displayed,
the sum power ratings measured by the UMG 96RM­EL must also be correct. For confirmation, the sum
power ratings measured by the UMG 96RM-EL should
be compared with the energy of the active and reactive
power meters at the power feed.

Comparators and monitoring threshold values

Two comparator groups (1-2) and 3 comparators per
group (A – C) can be selected in order to monitor/control
the thresholds. The results of the comparators A to C
can be linked with AND or OR operators

The address of the measured value to be monitored
by comparator A:
Address 110 = 866
(address of the current in the neutral line)

The measured values for the B and C comparators
are set to 0.
Address 116 = 0 (the comparator is inactive)
Address 122 = 0 (the comparator is inactive)

The limit value to be observed.
Address 108 = 100 (100 A)

56

For a minimum exposure time of 2 minutes, the result
of the comparator group 1 should be latched if the
limit value is exceeded.
Address 111 = 120 seconds

For the lead time of 60 seconds, any exceeding
should be minimised.
Address 112 = 60 seconds

The operator for comparison between the measured
value and the limit value.
Address 113 = 0 (corresponds >=)

2. Linking comparators
The B and C comparators have not been set and are
equal to zero.
The result of comparator A is issued as a comparator
result through the OR link of comparators A, B and C.
Address 107 = 0 (OR link)

Result
The result of the comparator group 1 is latched for at
least 2 minutes if the current in the neutral line is greater
than 100 A for more than 60 seconds.

UMG 96RM-EL

• Measured value (addr. 110,116,122,129,135,141)

The address of the measured value to be monitored
is in the measured value.
If measured value = 0, the comparator is inactive.

• Limit value (addr. 108,114,120,127,133,139)

Write the value in the limit that is to be compared with
the measured value.

• Minimum turn-on time
(addr. 111,117,123,130,136,142)

The linkage result (e.g. address 610) is maintained
for the duration of the minimum turn-on time.
Adjustment range: 1 to 32,000 seconds

• Lead time (addr. 112,118,124,131,137,143)

If a limit value violation is present for at least the
duration of the lead time, the comparator result is
changed.
Times in the range from 1 to 32,000 seconds can

be assigned to the lead time.

• Operator (addr. 113,119,125,132,138,144)

Two operators are available for comparing the
measured value and the limit value.
Operator = corresponds to 0 greater than or equal
to (>=)
Operator = corresponds to 1 less than (<)

58

• Comparator result (addr. 610,611,612,613,614,615)

The result from the comparison between the measured
value and the limit value is in the comparator result.
Therefore:
0 = there is no limit value violation.
1 = there is a limit value violation.

• Total running time

The sum of all times for which there was a limit value
violation in the comparator result.

• Linkage (addr. 107, 126)

Link the results from comparators A, B and C as AND
or OR.

• Total linkage result (addr. 616,617)

The linked comparator results from comparators A, B
and C are in the total linkage result.
