Product description
Proper use
The UMG 96RM-P/-CBM 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-P/-CBM is suitable for integration
into fixed and weatherproof switch panels. Conductive
switch panels must be earthed. Can be installed in any
attitude.
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 interfaces.
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 of the UMG 96RM-P/
-CBM are connected via external ../1A or ../5A current
transformers.
The measurement in medium and high voltage
networks is implemented in principle via current and
voltage transformers. The UMG 96RM-P/-CBM can be
employed both domestically and in industry.

UMG 96RM-P/-CBM
Current measurement via I1 to I4
The UMG 96RM-P/-CBM 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-P/-CBM.
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.

Caution!
The UMG96RM is only approved for a
current measurement using the current
transformer.
Current transformer connections!
The secondary connection of the current
transformer must be short-circuited on this
before the current feed to the UMG 96RMP/-CBM 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.
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 trans­
formers“ 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.

• All devices are connected in a bus structure (line) and
each device has its own address within the bus (also
see programming parameters).
• Up to 32 stations can be interconnected in one
segment.
• The cable is terminated with resistors (bus termination,
120 ohm 1/4 W) at the beginning and end of a segment.
• If there are more than 32 stations, repeaters (line
amplifiers) must be used in order to connect
the individual segments.
• Devices with activated bus termination must
be supplied with power.
• It is recommended to set the master at the end
of a segment.
• The bus is inoperative if the master is replaced with
an activated bus termination.
• The bus can become unstable if the slave is replaced
with an activated bus termination or is dead.
• Devices that are not involved in the bus termination
can be exchanged without making the bus unstable.

Parameters and measured values
Example of the parameter display
All parameters necessary for operating the UMG
96RM-P/-CBM, 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 96RMP/-CBM.
On the UMG 96RM-P/-CBM
display the value “001”
is shown as the content
of address “000”. This
parameter reflects the device
address (here “001”) of the
UMG 96RM-P/-CBM on a
bus in list form.
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 RS485 interface.

Configuration
Applying the supply voltage
To configure the UMG 96RM-P/-CBM, the supply
voltage must be connected.
The level of supply voltage for the UMG 96RM-P/-CBM
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-P/-CBM 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.

Device address (addr. 000)
Mean value
If several devices are connected to one another
via the RS485 interface, a master device can only
differentiate between these devices by means of their
device addresses. Therefore, each device in a network
must have a different device address. Addresses can be
set in the range from 1 to 247.
Mean values are formed over an adjustable

to 255 are reserved and may not be used.
Baud rate (addr. 001)
A common baud rate is adjustable for the RS485

Averaging method
Minimum and maximum values
After the set averaging time, the exponential averaging
method used achieves at least 95% of the measured
value.
All measured values are measured and calculated every
10/12 periods. Minimum and maximum values are determined for most of the measured values.
The minimum value is the smallest measured value that
has been determined since the last reset. The maximum value is the largest measured value that has been
determined since the last clearance. All minimum and
maximum values are compared with the corresponding
measured values and are overwritten if they are undercut
or exceeded.
The minimum and maximum values are stored in an EEPROM every 5 minutes, without the date and time. This
means that if the operating voltage fails, only the minimum and maximum values of the last 5 minutes are lost.
Clearing minimum and maximum values (addr. 506)
If "001" is written to the address 506, all minimum
and maximum values are simultaneously cleared.
56
UMG 96RM-P/-CBM
Mains frequency (addr. 034)
For automatic ascertainment of the mains frequency, an
L1-N voltage larger than 10Veff must be applied to the
voltage measurement input V1.
The mains frequency is then used to calculate the
sampling rate for the current and voltage inputs.
Adjustment range: 0, 45 .. 65
0=
automatic frequency determination.
The mains frequency is determined from
the measurement voltage.
45..65 = fixed frequency
The mains frequency is preselected.
If there is no measurement voltage, the mains frequency
cannot be determined and thus no sampling rate can be
calculated. The acknowledgeable error message “500”
appears.
The voltage, current and all other resulting values
are calculated based on the previous frequency
measurement and possible cable-connecting sockets
and continue to be displayed. However, these derived
measured values are no longer subject to the specified
accuracy.
If it is possible to re-measure the frequency, then the
error message will disappear automatically after a
period of approx. 5 seconds once the voltage has been
restored.
The error is not displayed if a fixed frequency has been
configured.

only be cleared together.
Address 507 must be written with "001" in order to clear
the contents of the energy meters.
If a user password was programmed, the password
menu will appear with the display "000".
The first digit of the user password flashes and can
be changed with button 2. The next digit is selected
by pressing button 1 and will begin flashing.
The programming menu for the current transformer can
only be accessed after entering the correct number
combination.
Forgotten password
If you have forgotten the password, the password can

UMG 96RM-P/-CBM
Rotation field direction
LCD contrast (addr. 035)
The rotation field direction of the voltages and the
frequency of phase L1 are shown on the display.
The rotation field direction indicates the phase sequence
in three-phase systems. Usually there is a "clockwise
spinning rotation field".
The phase sequence at the voltage measurement inputs
is checked and displayed in the UMG 96RM-P/-CBM.
A movement of the character string in the clockwise
direction means a "right rotation" and a counterclockwise movement indicates a "left rotation".
The rotation field direction is determined only if
the measurement and operating voltage inputs are fully
connected. If one phase is missing or two of the same
phases are connected, the rotation field direction will not
be determined and the character string does not appear
on the display.
The preferred direction of viewing for the LCD is from
"below". The user can adjust the LCD contrast of the
LCD screen. It is possible to set the contrast in the range
from 0 to 9 in steps of 1.
0 = characters are very light
9 = characters are very dark
Factory default setting: 5
Backlight
The LCD backlight allows the display to be read easily
even in poor light. The brightness can be controlled by
the user in stages from 0 to 9.
The UMG 96RM has two different types of backlight:
- the operation backlight
- the standby backlight

Time recording
The UMG 96RM-P/-CBM records the operating hours
and the total running time of each comparator
• where the time of operating hours is measured with
a resolution of 0.1 h and is displayed in hours or
• the total running time of the comparator is represented
in seconds (when 999999 seconds is reached,
the display changes to hours).
For the querying of measured value displays, the times
are marked with the numbers 1 to 6:
none = operating hours meter
1 = total running time, comparator 1A
2 = total running time, comparator 2A
3 = total running time, comparator 1B
4 = total running time, comparator 2B
5 = total running time, comparator 1C
6 = total running time, comparator 2C
A maximum of 99999.9 h (= 11.4 years) can be shown
on the measured value display.
UMG 96RM-P/-CBM
Operating hours meter
Serial number (addr. 754)
The operating hours meter measures the time for which
the UMG 96RM-P/-CBM records and displays measured
values.
The time of operating hours is measured with a resolution
of 0.1 h and is displayed in hours. The operating hours
meter cannot be reset.
The serial number shown by UMG 96RM-P/-CBM
has 6 digits and is part of the serial number displayed
on the nameplate.
The serial number cannot be changed.
Total running time of the comparator
The total running time of a comparator is the sum
of all time for which there is a limit value violation
in the comparator result.
The total running time of the comparator can only
be reset via the GridVis software. The reset is carried out
for all total running times.

Commissioning
Applying the measured current
Applying the supply voltage
The UMG 96RM-P/-CBM 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 96RMP/-CBM with the applied current.
The current displayed by the UMG 96RM-P/-CBM must
match the input current, taking the current transformer
ratio into consideration.
In the short circuit current measurement inputs,
the UMG 96RM-P/-CBM must show approx. zero amperes.
• The level of supply voltage for the UMG 96RM-P/
-CBM can be found on the nameplate.
• After applying the supply voltage, the UMG 96RM-P/
-CBM 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-P/-CBM must match
those at the voltage measurement input.

Attention!
Voltages and currents outside the permissible metering range can result in personal
injury and damage to the device.
The factory-set current transformer ratio is 5/5 A and may
need to be adapted to the current transformer used.

Attention!
Supply voltages that do not correspond
to the nameplate information can lead
to device malfunction or destruction.
Attention!
The UMG 96RM-P/-CBM is not suitable for
the measurement of DC voltages.
UMG 96RM-P/-CBM
Rotation field direction
Checking the measurement
Check the direction of the voltage rotation field on the
measured value display of the UMG 96RM-P/-CBM.
Usually there is a "clockwise" spinning rotation field.
If all voltage and current measurement inputs are
correctly connected, the individual and sum power
ratings are accurately calculated and displayed.
Checking the phase assignment
Checking the individual power ratings
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-P/-CBM in the corresponding
phase sinks to 0A.
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-P/-CBM 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-P/-CBM must then be
zero in this phase.
Checking the power measurement
Short circuit all current transformer outputs except for
one and check the displayed power. The UMG 96RMP/-CBM 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.
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.
69
UMG 96RM-P/-CBM
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 96RM-P/
-CBM must also be correct. For confirmation, the sum
power ratings measured by the UMG 96RM-P/-CBM
should be compared with the energy of the active and
reactive power meters at the power feed.

Profibus interface (only UMG 96RM-P)
Activate outputs/tariffs via Profibus
Profibus profiles
To set the outputs or the tariffs an appropriate profile must
be selected. Alongside the 1st byte used for the profile
selection three further bytes can be used to:
A Profibus profile contains the data to be exchanged
between a UMG and a PLC. It is possible to read out
measurement values and statuses via eight user-defined
and four factory pre-configured Profibus profiles.
A Profibus profile can:
• Retrieve measurement values from the UMG.
• Set the digital outputs in the UMG.
• Query the status of the digital inputs in the UMG.
• Switch outputs
• Control tariffs and energy meters
Profile number selection (1st byte):
Byte 1 enables the selection of the Profibus profile
number 0 to 11. The output range of the PLC must
contain this byte as a minimum. Within the byte, bits 0
to 3 describe the profile number, bits 4 to 7 are unused.
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.
• The 8 user-defined Profibus profiles (profile
numbers 0...7) can be edited with the GridVis
software.
• Factory pre-configured Profibus profiles (profile
numbers 8...11) cannot be changed.

Deactivate energy meters / tariffs via Profibus
If energy meters are assigned to a tariff then these
can be deactivated via byte 3 and byte 4 (cf. activate
tariffs via Profibus). Here the selection of the desired
tariff is implemented in byte 3 and the clearing of the
associated bits in byte 4 deactivates the energy meter.
Example:
If the energy meter for active energy (drawn) is set
under tariff 3, the deactivation of the energy meter
is implemented as follows:

Reading out measurement values via the Profibus
Selected measurement values can be read out
via 4 factory-set profiles and an additional 8 userdefined profiles. Here each profile has a unique profile
number with which a PLC can read out the configured
measurement values of a profile.
Example:
Reading out of measurement values from the factorypreconfigured Profibus profile number 8.
The 1st byte should be set to the profile number 8 (dec.)
and sent to the UMG 96RM-P.
The UMG 96RM-P then delivers the profile number 8
and the measured values set in profile 8 back.

Pulse value (addr. 102, 104)
The pulse value specifies 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 the pulse value is specified with a positive sign,
pulses will only be issued if the measured value also
has a positive sign.
If the pulse value is specified with a negative sign,
pulses will only be issued if the measured value also
has a negative sign.

Firmware update
Battery
If the device is connected to a computer via Ethernet,
then the device firmware can be updated via the GridVis
software.
The internal clock is fed from the supply voltage.
If the supply voltage fails then the clock is powered
by the battery. The clock provides date and time information, for the records, min. and max. values and results, for example.
Select a suitable update file (menu Extras / Update device) and the device and the new firmware will be transferred.
The life expectancy of the battery is at least 5 years with
a storage temperature of +45°C. The typical life expectancy of the battery is 8 to 10 years.
The battery is replaced via the battery insert provided
on the rear of the device. Make sure that the correct
type of battery is used and correct polarity is observed
when inserting the battery (positive pole faces the rear
of the device; negative pole faces the front).
