Product description
Proper use
The UMG 96RM-PN is intended for the measurement and calculation of electrical variables such as voltage, current, power, energy, harmonics, etc. in building installations, on distribution units, circuit breakers and busbar trunking systems.
The UMG 96RM-PN is suitable for integration into fixed and weatherproof switch panels. Conductive switch panels must be earthed.
A continuous monitoring of residual currents (residual current monitor, RCM) is performed 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 are always performed via current and voltage transformers.
Measured voltages and measured currents must derive from the same network.
The measurement results can be displayed and read out and further processed via the RS485 or ProfiNet interface.
The voltage measurement inputs are designed for measurements in low voltage networks where rated voltages of up to 300V phase to earth and surge voltages of overvoltage category III can occur.
The current measurement inputs I1-I4 of the UMG
96RM-PN are connected via external ../1A or ../5A current transformers.

UMG 96RM-PN
Current measurement using I1 to I4
The UMG 96RM-PN is intended for the connection of current transformers with secondary currents of ../1A and ../5A, via 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 with the UMG 96RM-PN.
Only AC currents can be measured - DC currents cannot.
Current measurement input I4 only produces an apparent current measurement, due to there being no multiplier with a voltage. Power measurements are therefore not possible with input I4.
c
22
Attention!
The current measurement inputs are dangerous to touch.

UMG 96RM-PN
Current direction
The current direction can be individually corrected via the existing serial interfaces or on the device for each phase.
If incorrectly connected, a subsequent re-connection of the current transformer is not required.
c
Attention!
Residual current monitoring is performed using the terminals I5 and I6 (cf. page
30). There is no directional sensitivity of the residual currents of the network or load sides (not directionally sensitive).
With residual current monitoring (RCM) there is no directional sensitivity of the residual currents on the network or load sides (not directionally sensitive).
c
Earthing of current transformers!
If a connection is provided for the earthing of secondary windings, then it must be connected to the earth.
c
Current transformer connections!
The secondary connection of the current transformer must be short circuited on this before the current feed to the UMG 96RM-
PN 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.
24 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.
c
Attention!
The UMG96RM is only approved for measuring current with a current transformer.

Analogue inputs
The UMG 96RM-PN has two analogue inputs, each of which can be used for a residual current measurement or a temperature measurement. A measurement is performed here via terminals 32-34 (Input 1) and 35-37
(Input 2).
c
Attention!
Operating equipment connected to the analogue inputs must feature reinforced or double insulation to the mains supply circuits!
The analogue inputs can be used either for residual current measuring or temperature measuring, per the following table:

Terminal
32/34 (Input 1) and
35/37 (Input 2)
32/33/34 (Input 1) and

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-PN
Residual current monitoring (RCM) via I5, I6
The UMG 96RM-PN is suitable for use as a residual current monitoring device (RCM) as well as for monitoring
AC, pulsing DC, and DC.
The UMG 96RM-PN can measure residual currents in accordance with IEC/TR 60755 (2008-01) of type A and type B.
The connection of suitable external residual current transformers with a rated current of 30 mA is performed via the residual current transformer inputs I5 (terminals
32-34) and I6 (terminals 35-37).

Screening Cable type
Twisted screened cable should be used for connections via the RS485 interface.
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 and at the cabinet entry.
• 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.
Recommended cable types:
Unitronic Li2YCY(TP) 2x2x0.22 (from Lapp Kabel)
Unitronic BUS L2/FIP 1x2x0.64 (from Lapp Kabel)

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 than 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.
• The shield has to be installed continuously and needs to be broadly and well conducting connected to an external low voltage (or potential) ground at the end.

Ethernet / ProfiNet interface
The Ethernet network settings should be specified by the network administrator and set on the UMG 96RM-
PN accordingly.
If the network settings are not known, the UMG 96RM-
PN may not be integrated into the network through the patch cable.
The UMG 96RM-PN has two identical Ethernet interfaces.
This allows another Ethernet/ProfiNet terminal to be operated via the second interface, thus reducing outlay on cabling.

PROFIenergy / Entity Class 2
The UMG 96RM-PN is certified as
Entity Class 2 (measurement functionality) for use of the PROFIenergy
Profile V1.1.
C
Dynamic Configuration Protocol (DCP)
This function assigns unique addresses and names to the subscribers of a
ProfiNet system, and is prioritised by the UMG 96RM-PN.
• A PROFIenergy device provides a defined set of functions and information, helping to standardise and reduce configuration and installation effort.
Device master file
The device master file, abbreviated as GSD file, describes the ProfiNet characteristics of the UMG96RM-
PN. The GSD file is required, for example, by the configuration program of the PLC.
The device master file for the UMG96RM-PN has the file name "GSDML-V2.31-JanitzaelectronicsGmbH-
UMG96RM-PN-xxxxxxxx.xml" and is included on the data carrier as part of the scope of the delivery.
• PROFIenergy is a profile for energy management in production systems, which is based on ProfiNet.
• Energy consumers within the system can therefore be controlled and monitored with PROFlenergy using open and standardised commands.
• With automated comparison of functionality between the ProfiNet control centre and the UMG, additional configuration and installation is rendered unnecessary.

UMG 96RM-PN
Digital in-/outputs
The UMG 96RM-PN has 2 digital outputs and either
3 digital inputs or outputs, which are subdivided into two groups (see Figure, page 40). This is based on the rule that only the
whole of Group 2 (connection 28 to
31) can function either as an input or output; differing assignments within the same group are not possible!
Digital outputs, Group 2
• The status of the inputs and outputs in Group 2 is indicated by the associated LED (cf. chapter LED status bar).

Input/output byte coding
(Input/output data of the ProfiNet „digital IO“ module)
• If the digital inputs/outputs in group 2 are configured as inputs, bit-oriented coding of the statuses occurs
(bit 0 to 2). In this case, coding corresponds to the digital inputs with:
Bit 0 1 2 3 4 5 6 7
Input 3: 1 = signal is present
Input 2: 1 = signal is present
Input 1: 1 = signal is present
• The digital outputs can be controlled by setting the corresponding bits.
• If, for example, the digital inputs/outputs in group 2 are configured as outputs, bit-oriented coding occurs within bits 0 to 4:
Bit 0 1 2 3 4 5 6 7
Output 5: 1 = signal set
Output 4: 1 = signal set
Output 3: 1 = signal set
Output 2: 1 = signal set

Operation
Programming mode
The UMG 96RM-PN is operated with buttons 1 and 2, whereby the following distinctions are made:
• short press of button 1 or 2: next step (+1)
• long press of button 1 or 2: previous step (-1)
Measured values and programming data are presented on a liquid crystal display.
Programming mode displays and allows for the modification of the settings required for operation of the UMG 96RM-PN. Pressing and holding buttons 1 and 2 at the same time for approx. 1 second takes you
(after password prompt) to Programming mode. If no user password has been set up, you are taken directly to the first Programming menu. Programming mode is indicated on screen by the text "PRG".
A distinction is made between Display mode and
Programming mode. The requirement to enter a password makes it possible to prevent the programming data from being changed accidentally.
Button 2 then allows you to switch between the following
Programming menus:
Display mode
- Current transformer
- Voltage transformer
- Parameter list
- Device TCP/IP address
- Subnet mask
- Gateway address
In Display mode, using buttons 1 and 2, you can scroll through the programmed measured value screens. In the factory, all measured value screens listed in Profile
1 can be accessed. Up to three measured values are displayed on each measured value screen. The measured value rotation allows selected measured value screens to be displayed in turn after a configurable rotation time.
If you are in Programming mode and no button is pressed around 60 seconds or if buttons 1 and 2 are pressed simultaneously for around 1 second, the UMG
96RM-PN returns to Display mode.

Parameters and measured values Example of a parameter screen
All of the parameters required for operation of the UMG
96RM-PN, such as 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 with the buttons on the UMG
96RM-PN.
On the display of the UMG
96RM-PN the contents of address "000" is displayed as "001'. This parameter describes (according to the list) the device address of the UMG 96 RM-PN (in this case "001") within a bus.
On the device you can only enter the first 3 significant digits of a value. Values with more digits can be entered in GridVis.
The device only ever displays the first 3 significant digits of the value.
Selected measured values are summarised in measured value screen profiles, and can be displayed in Display mode with buttons 1 and 2.
Example of a measured value screen
In this example, the display of the UMG 96RM-PN shows each of the voltages L to N as 230V. Transistor outputs
K1 and K2 are active and a current can flow.
The current measured value screen profile, the current screen rotation profile and date and time can only be read and modified via the RS485 interface.

Configuration
Connecting the supply voltage
The supply voltage must be connected for the configuration of the UMG 96RM-PN.
c
Attention!
If the supply voltage does not correspond to the voltage indicated on the rating plate, this may lead to malfunctions and severe damage to the device.
The supply voltage level for the UMG 96RM-PN is specified on the rating plate.
If no screen appears, check whether the supply voltage is within the rated voltage range.
C
The adjustable value 0 for the primary current transformer does not produce any meaningful work values, and must not be used.
Current and voltage transformer
A current transformer of 5/5A is set in factory. Only if voltage transformers are connected does the preprogrammed voltage transformer ratio need modifying. m
Devices based on automatic frequency detection require approx. 5 seconds to determine the mains frequency. During this time, the measured values do not comply with the promised measurement uncertainty.
When connecting voltage transformers, pay attention to the measured voltage specified on the rating plate of the UMG 96RM-PN!

Current and voltage transformer
The GridVis software can be used to individually program the transformation ratios for each current or voltage measurement input.
Only the transformation ratio for the respective group of current measurement inputs I1-I3 or voltage measurement inputs
V1-V3 can be set on the device.
The transformation ratio of current trans-
former input I4 and the residual current
transformer inputs I5, I6 must be set in the
GridVis software.
Current transformer input I4
Current transformer input I4 only produces an apparent current measurement, due to there being no multiplier with a voltage.
Power measurements with the input are therefore not possible. The transformation ratio can be set in the GridVis software.
Fig. Screen for configuration of the current and voltage transformer in the GridVis software.

All measured values are measured and calculated every
10/12 periods. Min. and max. values are determined for most measured values.
The min. value is the lowest measured value measured since the last time the values were cleared. The min. value is the lowest value measured since the last time the values were cleared. All min. and max. values are compared with the associated measured values, and overwritten if the value is under the min. value or over the max. value.
The min. and max. values are stored every 5 minutes to an EEPROM without the date and time. This means that, if there is failure of the supply voltage, only the min. and max. values for the last 5 minutes can be lost.
Clearing the min. and max. values (addr.506)
If "001" is written to address 506, all min. and max. values are cleared simultaneously.
58
UMG 96RM-PN
Mains frequency (addr. 034)
To automatically determine the mains frequency, a voltage L1-N of greater than 10Veff must be applied to voltage measurement input V1.
The sampling rate for the current and voltage inputs is then calculated from the mains frequency.
Setting range: 0, 45 - 65
0 = Frequency determined automatically
The mains frequency is determined from the measured voltage.
45 - 65 = Fixed frequency
The mains frequency is preset to a fixed value.
If the measured voltage is absent, it is not possible to determine the mains frequency, which makes it impossible to calculate the sampling rate. The acknowledgeable error message "500" appears.
Voltage, current, and all other values derived from these are calculated and still displayed based on the last frequency measurement or on possible line interfaces.
However, these determined measured values are no longer subject to the specified level of accuracy.
Once the frequency can be measured again, the error message disappears automatically approx. 5 seconds after the voltage returns.
The error is not displayed if a fixed frequency is set.

Harmonics Total Harmonic Distortion (THD)
Harmonics are the integer multiples of a fundamental oscillation.
On the UMG 96RM-PN the fundamental oscillation of the voltage must be in the range from 45 to 65 Hz. At this fundamental oscillation the calculated harmonics relate to the voltages and currents.
Harmonics up to 40 times the fundamental oscillation are captured.
THD is the ratio of the effective value of the harmonics to the effective value of the fundamental oscillation.
Total harmonic distortion of the current (THDI):
The harmonics for the currents are given in amps, the harmonics for the voltages in volts.

Measured value rotation Rotation time (addr. 039)
All measured values are calculated every 10/12 periods, and are available once a second in the measured value screens. Two methods are available for bringing up the measured value screens:
Setting range: 0 to 60 seconds
If 0 seconds is set, then there is no rotation between the measured value screens selected for measured value rotation.
The rotation time applies to all screen rotation profiles.
• The automatically rotating display of selected measured value screens, referred to here as
"measured value rotation".
• Choosing a measured value screen from a selected screen profile, using buttons 1 and 2.
Screen rotation profile (addr. 038)
Setting range: 0 to 3
0 - Screen rotation profile 1, preassigned.
1 - Screen rotation profile 2, preassigned.
2 - Screen rotation profile 3, preassigned.
3 - Screen rotation profile, customer-specific.
Both methods are available simultaneously. Measured value rotation is active when at least one measured value screen is programmed with a rotation time greater than
0 seconds.
Pressing a button allows you to scroll through the measured value screens for the selected screen profile. If no button is pressed for around 60 seconds, the device switches to measured value rotation, and the measured values from the selected screen rotation profile programmed measured value screens are displayed in succession.
Measured value screens
After the power is restored, the UMG 96RM-PN displays the first measured value table from the current screen profile. So that the selection of measured values to be displayed remains clear, at the factory only one part of the available measured values is pre-programmed to be called up in the measured value screen. If you desire to display other measured values on the screen of the UMG
96RM-PN, select a different screen profile.

UMG 96RM-PN
Direction of the rotating field LCD contrast (addr. 035)
The direction of the rotating field of the voltages and the frequency of phase L1 are displayed in a screen.
The direction of the rotating field specifies the phase sequence in three-phase power grids. A “right-hand rotation field” usually exists.
In the UMG 96RM-PN, the phase sequence is tested and indicated on the voltage measurement inputs. A movement of the character string in a clockwise direction means there is a “right-hand rotation field” and an anticlockwise movement indicates a “left-hand rotation field”.
The direction of the rotating field is only determined when the measuring and supply voltage inputs are fully connected. If a phase is missing or if two identical phases are connected, the direction of the rotating field is not established and the character string is stationary on the screen.
The preferred direction for observing the LCD display is from below. The contrast of the LCD display can be adjusted by the user. The contrast can be set in the range from 0 to 9 in steps of 1.
0 = Characters very bright
9 = Characters very dark
Factory default setting: 5
Backlight
The backlight enables good legibility of the LCD display under poor visual conditions. The brightness can be controlled by the user in the range from 0 to 9 in steps of 1.
The UMG 96RM-PN has two different types of backlight:
- Operating lighting
- Standby lighting

UMG 96RM-PN
Operating lighting (addr. 036):
The operating lighting is activated by the push of a button or upon restart.
Standby lighting (addr. 747)
This type of backlight is activated after a customisable period of time (addr. 746). If there are no button presses during this period, the device switches to standby lighting.
If buttons 1 - 3 are pressed, the device switches to operating lighting and the defined period begins again from scratch.
C
DCP "Identify Station" signal of the PLC:
If the PLC sends control signals for device identification to the device, the backlight switches between maximum and minimum brightness (causing the display lighting to "flash"). To achieve this there is usually a "Flash" button in the PLC.
If the brightness values are the same for both types of lighting then no change is discernible between the backlight and standby lighting.

Time logging
Operating hours counter
The UMG 96RM-PN logs the operating hours and the total running time of each comparator, whereby the time
• for the operating hours is measured with a resolution of 0.1 hrs and displayed in hours or
• the total running time of the comparators is displayed in seconds (when 999,999 secs is reached, the number is displayed in hours).
The operating hours counter measures the time in which the UMG 96RM-PN captures and displays measured values.
The time for the operating hours is measured with a resolution of 0.1 hrs and displayed in hours.
The operating hours counter cannot be reset.
Total running time, comparator
For a query using the measured value screens, the times are indicated with the numbers 1 to 6:
None = Operating hours counter
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 99,999.9 hrs (=11.4 years) can be shown on the measured value screen.
The total running time of a comparator is the sum of all times for which there was a threshold value violation in the comparator result.
The total running times of the comparators can only be reset via the GridVis software. The reset is performed for all total running times.

Operating hours counter
The UMG 96RM-PN shows the number 140.8 hrs in the operating hours counter. This corresponds to 140 hours and 80 industry minutes. 100 industry minutes correspond to 60 minutes. In this example, the 80 industry minutes correspond to 48 minutes.

Applying the measuring-circuit voltage
Commissioning
Connecting the supply voltage
• The supply voltage level for the UMG 96RM-PN is specified on the rating plate.
• After applying the supply voltage, the UMG 96RM switches to the first measured value screen.
• If no display appears, check whether the power supply voltage is within the rated voltage range.
Connecting the measured voltage
• Measurement of voltages in networks with over
300VAC to earth must be connected via voltage transformers.
• After connecting the measured voltages, the measured values displayed by the UMG 96RM-PN for the L-N and L-L voltages must correspond to those at the voltage measurement input.
The UMG 96RM-PN 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-PN must correspond with the input current.
The UMG 96RM-PN 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. m
Attention!
If the supply voltage does not correspond to the voltage indicated on the rating plate, this may lead to malfunctions and severe damage to the device.
m
Attention!
Voltages and currents that are outside the permissible measurement range can cause personal injury and lead to the destruction of the device.
m
Attention!
The UMG 96RM is not suitable for measuring DC voltages.
68
UMG 96RM-PN
Direction of the rotating field Applying the residual current
Check the direction of the rotating field voltage in the measured value display of the UMG 96RM.
A “right-hand” rotation 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.
Checking the phase assignment
The phase conductor assignment to the current transformer is correct if a current transformer is short-circuited on the secondary side and the current displayed by the UMG
96RM-PN drops to 0A in the associated phase.
Checking the power measurement
Bearing in mind the current transformer ratio, the residual current displayed by the UMG96RM-PN must correspond with the input current.
The current transformer ratio is factory-set to 1/1A 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-PN 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 measured voltage and the measuring-circuit current.
If the effective power amount is correct but the sign of the power output is negative, this could have two possible causes:
• S1(k) and S2(l) are reversed at the current transformer.
• Effective energy is being supplied back into the network.
C
The UMG96RM-PN requires the mains frequency for residual current monitoring. For this purpose, the measured voltage should be applied or a fixed frequency should be set.
C
It is not necessary to configure a connection schematic for residual current inputs I5 and I6.
69
UMG 96RM-PN
Failure monitoring (RCM) for I5, I6
The UMG96RM-PN enables continuous monitoring of the connection to the residual current transformer on inputs I5 and I6.

UMG 96RM-PN
Checking the measurement Checking the sum powers
Once all voltage and current measurement inputs are properly connected, the signal phase and sum powers are also calculated and displayed properly.
Checking the single phase powers
If a current transformer is assigned to the wrong phase conductor, the associated power will also be measured and displayed incorrectly.
The assignment of phase conductor to current transformer on the UMG 96RM-PN is correct when there is no voltage between the phase conductor and the associated current transformer (primary).
To ensure that a phase conductor on the voltage measurement input is assigned to the right current transformer, you can short-circuit the current transformer in question on the secondary side. The apparent power displayed by the UMG 96RM-PN must be zero in this phase.
If all voltages, currents, and powers for the phase conductor in question are displayed properly, then the sum powers measured by the UMG 96RM must also be correct. For confirmation, the sum powers measured by the UMG 96RM should be compared with the effective and reactive power meter located in the supply.
If the apparent power is displayed correctly but the effective power has a "-" sign, the current transformer terminals are reversed or power is being supplied to the power company.

UMG 96RM-PN
Pulse value (addr. 102, 104)
The pulse value is used to indicate how much power (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.
Pulse value = max. connected load max. number of pulses/h
[Pulse/Wh]
C
Since the effective energy meter operates with a backstop, pulses will only be generated when drawing electricity.
C
Since the reactive energy meter operates with a backstop, pulses will only be generated with inductive load applied.

Determine the pulse value
Set the pulse length
Set the pulse length in accordance with the requirements of the connected pulse receiver.
At a pulse length of 30 ms, for example, the UMG 96RM generates a maximum number of
60,000 pulses (see Table "maximum number of pulses" per hour.
Determining the maximum connected load
Example:

Voltage L-N
= 150/5 A
= Max. 300 V
Power per phase = 150 A x 300 V

Two comparator groups (1 - 2), each with 3 comparators
(A - C) are available to monitor threshold values.
The results of Comparators A to C can be combined with the AND/OR operators.
The combination result of Comparator group 1 can be assigned to Digital output 1 and the combination result of Comparator group 2 can be assigned to Digital output
2.
Additionally, the function "Flash display" can also be assigned to each comparator group, whereby the backlight of the screen alternates between maximum and minimum brightness when a comparator output is active.

Example: current monitoring on the N
If the current on the N is higher than 100 A for 60 seconds, then Digital output 1 should be active for at least 2 minutes.
The following programming must be undertaken:
The exceedance should be present at least for the lead time of 60 seconds.
Addr. 112 = 60 seconds
1. Comparator group 1
Select Comparator group 1 for threshold value monitoring.
The comparator group only has an effect on Digital output 1.
Since only one threshold value is being monitored, select
Comparator A and program it as follows:
The operator for the comparison between measured value and threshold value.
Addr. 113 = 0 (meaning >=)
2. Selection of source
Select Comparator group 1 as the source.
Addr. 200 = 0 (Comparator group 1)
The address of the measured value of Comparator A to be monitored:
Addr. 110 = 866 (address of the current on the N)
3. Inverter
The result from Comparator group 1 can also be inverted here. However, we will not do so here.
Addr. 201 = 0 (not inverted)
The measured values for Comparators B and C are 0.
Addr. 116 = 0 (the comparator is inactive)
Addr. 122 = 0 (the comparator is inactive)
The threshold value to be observed.
Addr. 108 = 100 (100 A)
4. Combine the comparators
Comparators B and C were not set and equal zero.
Using the OR operator on Comparators A, B and C, the result of Comparator A is output as the comparator result.
Addr. 107 = 0 (combine with the OR operator)
Digital output 1 should remain active for a min. switch-on time of 2 minutes if the threshold value is exceeded.
Addr. 111 = 120 seconds
Result
If the current on the N is higher than 100 A for over 60 seconds, then Digital output 1 is active for at least 2 minutes.
Digital output 1 becomes active. A current can flow.

UMG 96RM-PN
• Measured value (addr. 110,116,122,129,135,141)
The measured value contains the address of the measured value to be monitored.
Measured value = 0 the comparator is inactive.
• Threshold value (addr. 108,114,120,127,133,139)
The threshold value is where you write the value to be compared with the measured value.
• Comparator result (addr. 610,611,612,613,614,615)
The result of the comparison between the measured value and threshold value is in the comparator result.
In this context:
0 = There is no threshold value violation.
1 = There is a threshold value violation.
• Total running time
The sum of all times for which there was a threshold value violation in the comparator result.
• Min. switch-on time (addr. 111,117,123,130,136,142)
The logic operation result (e.g. Addr. 610) is retained for the duration of the min. switch-on time.
Setting range: 1 to 32,000 seconds
• Combine (addr. 107,126)
Combine the results of Comparators A, B, and C with the AND/OR operators.
• Lead time (addr. 112,118,124,131,137,143)
Only if there is a threshold value violation for at least the duration of the lead time is the comparator result modified.
The lead time can be assigned to times in the range from 1 to 32,000 seconds.
• Total combination result (addr. 616,617)
The combined comparator results of Comparators A,
B, and C are in the total combination result.
• Operator (addr. 113,119,125,132,138,144)
Two operators are available for comparing the measured value and the threshold value.
Operator = 0 means greater than or equal to (>=)
Operator = 1 means less than (<)
86
UMG 96RM-PN
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!
Threshold value
Threshold value violation (e.g. exceedance)
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.

Error / warning messages
Warnings
The UMG 96RM-PN can show four different error messages on the display:
• Warnings
• Serious errors
• Measurement range exceeded
Error messages for warnings and serious errors are depicted with the symbol "EEE" followed by an error number.
Warnings are less serious errors and must be acknowledged with button 1 or 2. The capture and display of measured values continues. This error is displayed again each time the power is switched on.
Fig. Warning message with number 500 (mains frequency)
The three-digit error number is composed of the error description and - if this can be established by the UMG
96RM - one or more causes for the error.

The display only depicts the first 3 digits
(###) of a value. Values higher than 1000 are indicated by "k". Example: 003k = 3000
* The tariff counter is activated by a bit-by-bit coding:
Bit 0 = Effective energy, Bit 1 = Effective energy (consumed), Bit 2 = Effective energy (delivered)
Bit 3 = Reactive energy, Bit 4 = Reactive energy (inductive), Bit 5 = Reactive energy (capacitive)
Bit 6 = Apparent energy

Basic functions quick guide
Modify current transformer setting
Switch to Programming mode:
• Switching to Programming mode is done by pressing buttons 1 and 2 simultaneously for approx. 1 second.
The symbols for Programming mode "PRG", and for the current transformer "CT" appear.
• The selection is confirmed with button 1.
• The first digit of the input range for the primary current flashes.
Modify primary current
• Modify the flashing digit with button 2.
• Use button 1 to select the next number you wish to modify. The selected digit to be modified flashes. If the entire number flashes, the decimal point can be moved with button 2.
Modify secondary current
• Only 1A or 5A can be set as the secondary current.
• Use button 1 to select the secondary current.
• Modify the flashing digit with button 2.
Exit Programming mode
• Switching to Display mode is done by pressing buttons
1 and 2 again simultaneously for approx. 1 second.
Retrieving measured values
Current transformer setting, primary current
Programming mode indicator
Current transformer setting, secondary current
Current transformer symbol
(only in Programming mode)
Switch to Display mode:
• If Programming mode is still active (PRG and CT symbols shown on the display), pressing buttons 1 and 2 simultaneously for approx. 1 second switches to Display mode.
• A measured value screen, e.g. for the voltage, appears
Button control
• Button 2 is used to switch between the measured value screens for current, voltage, power, etc.
• Button 1 is used to switch between the mean values, max values, etc. associated with a particular measured value.

TCP/IP addressing quick guide
Manual TCP/IP settings
Switch to Programming mode:
• Switching to Programming mode is done by pressing buttons 1 and 2 simultaneously for approx. 1 second.
The symbols for Programming mode "PRG", and for the current transformer "CT" appear.
Set the TCP/IP address (addr.)
• Use button 2 to switch to "Adr" on the display.
• Use button 1 to select the first digit of the address
(Byte 0) (digit flashes). Select the digit with button 2.
• Select the next digit with button 1 (digit flashes) and use button 2 to set the desired digit.
• Once Byte 0 of the address is set, bytes 1 to 3 can be set with button 1. Then the display jumps back to Byte
0 ( none of the digits are flashing).
Subnet mask (SUb)
• Use button 2 to switch to the subnet mask area and set it with buttons 1 and 2, in the same way as the address.
Set gateway address (GAt)
• Use buttons 2 and 1 to set the gateway in the same way as the address.
Exit Programming mode
• Exit the mode by pressing buttons 1 and 2 simultaneously, or wait for 60 seconds.
