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.
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.
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 I1I4 of the UMG 96RME are connected via
external ../1A or ../5A current 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!
10
UMG 96RM-E
For Janitza measurement devices and components, use only current transformers
intended for measuring purposes (“transformers”)!
“Transformers”, unlike “protection transformers”, go into saturation at high
current peaks. “Protection transformers” do not have this saturation behavior
and can therefore significantly exceed the rated values in the secondary
circuit. This can overload the current measurement inputs of the measurement
devices!
Furthermore, please note that Janitza measurement devices and components are
not to be used for critical switching, control or protection applications
(protective relays)! Observe the safety and warning information in the
“Installation” and “Product safety” chapters!
The UMG 96RM-E can be used in industrial and domestic settings.

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

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.
c
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
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.
c
26
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
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.

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).
c
Attention! Operating equipment connected to the analogue inputs must exhibit reinforced or double insulation from mains supply circuits!
The analog inputs can be used for residual current or temperature measurement in accordance with the following table:
Measurement Temperature
Residual current
Terminal
32/34 (input 1) and 35/37 (input 2)
32/33/34 (input 1) and 35/36/37 (input 2)
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.

The applied exponential messaging method reaches at least 95% of the
measurement value once the reporting time has run its course.
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.
UMG 96RM-E
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 sampling frequency is computed for the current and voltage inputs based on
the mains frequency.
Setting range: 0, 45 .. 65 0 = automatic frequency determination. The mains frequency is determined based on the measurement voltage. 45..65 = fixed frequency The mains frequency is pre-selected as a fixed value.
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.

Phase sequence
LCD contrast (Addr. 035)
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-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.
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.
0 = very bright 9 = very dark

· 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.
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.

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.
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.
Checking the energy measurement
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.
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.
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
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.

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.
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 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.
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.

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.

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
Limit value
Limit value violation (e.g. exceedance)
· 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.

Firmware update
Battery
If the device is connected to a computer via Ethernet, then the device
firmware can be updated via the GridVis software.
Select a suitable update file (menu Extras / Update device) and the device and
the new firmware will be transferred.
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.
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).

Replacing the battery
If the battery capacity is shown as < 75 %, we recommend that the battery be replaced.
Procedure 1. Disconnect system and device from power supply
before beginning work. 2. Discharge any electrostatic charge in your body,
e. g. by touching an earthed cabinet or metal part (radiator) connected to the
earth of the building. 3. Remove the battery from the battery compartment,
–e.g. using long-nose pliers–. The device does not need to be opened to do
this as the battery compartment can be accessed from the outside (see figure
on the right). 4. Make sure that the polarity is as shown on the insertion
opening of the battery compartment and slide the replacement battery into the
battery compartment. For this, use a battery compliant with the description in
the technical data. The battery must fulfil the safety requirements of UL1642.
Otherwise, there is a risk of combustion or explosion. 5. Dispose of the old
battery according to the legal regulations. 6. Start up the system and the
device again and check the functionality of the UMG 96-RM. Set the date and
time.
