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.

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. Load L1 L2 L3 c Caution! The test leads must be designed for an operating temperature of at least 80°C. Fig. Current measurement (I1-I3) via current transformers (connection example) c Caution! The current measurement inputs are dangerous to touch. m 22 N The attached screw terminal has to be fixed sufficiently with two screws on the device! m Caution! The UMG 96RM-E is not suitable for measuring DC voltages. C It is not necessary to configure a connection schematic for the I4 measurement input. N L3 L1 Earthing of current transformers! If a connection is provided for the earthing of secondary windings then this must be connected to the earth. Load c L2 UMG 96RM-E Fig. Current measurement (I4) via current transformer (connection example) 23 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 c Caution! The UMG96RM is only approved for a current measurement using the current transformer. 25 UMG 96RM-E Wiring diagrams, current measurement (I1-I3) • 3p 4w (Addr. 510= 0), factory setting • 3p 2i (Addr. 510 = 1) L1 L1 L2 L2 L3 N L3 N I1 I2 I3 Fig. Measurement in a three-phase network with non-uniform load. • 3p 2i0 (Addr. 510 = 2) I1 • 3p 3w3 (Addr. 510 = 3) L1 L2 L2 L3 L3 I2 I3 Fig. The measured values for the current measurementinput I2 are calculated. 26 I3 Fig. System with uniform phase loading.

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 UMG 96RM-E is for use as a residual current monitoring device (RCM), suitable for monitoring AC, pulsing DC, and DC.

If no display appears, check whether the operating voltage lies within the nominal voltage range. Current and voltage transformers When the device is delivered, a current transformer ratio of 5/5A is entered. The voltage transformer ratio must only be changed if a voltage transformer is connected. C m When connecting a voltage transformer, please note the measurement voltage of UMG 96RM-E given on the rating plate. C 48 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. The adjustable value 0 for the primary current transformer does not produce any useful work data, and should not be used. Devices with an automatic frequency detection require about 5 seconds to determine the mains frequency. In the meantime, measured values do not maintain the guaranteed measurement uncertainty. Prior to commissioning potential production dependant contents of the energy counter, min/max values and records have to be deleted. UMG 96RM-E C Current and voltage transformers The GridVis software included with delivery can be used to individually program the current and voltage transformer input transformer ratios. Only the transformer ratio of the respective group of the current inputs I1-I3 and the voltage measurement inputs V1-V3 can be adjusted on the device. The transformer ratio of the current transformer input I4 and the residual current transformer inputs I5, I6 should be set in the GridVis software.

Within a network, each device must have its own device address. Addresses can be set in the range of 1 to 247. A common baud rate can be adjusted for the RS485 interfaces. The baud rate must be uniform for all devices on the network. Address 003 can be used to set the number of stop bits (0=1bit, 1= 2bits). Data bits (8) are fixed default values. C 56 The adjustable range of the device address is between 0 and 255. Values 0 and 248 through 255 are reserved and may not be used.

More information can be found in the GridVis assistant. 57 UMG 96RM-E Parameter Averaging method Mean value The applied exponential messaging method reaches at least 95% of the measurement value once the reporting time has run its course. Mean values are averaged over an adjustable period for the current, voltage and power measured values. The mean values are indicated by a bar over the measured value. The averaging time can be selected from a list with 9 fixed averaging times. Averaging time, current (Addr. 040) Averaging time, power (Addr. 041) Averaging time, voltage (Addr. 042) 58 Setting Averaging time/sec. 0 1 2 3 4 5 6 7 8 5 10 15 30 60 300 480 (factory setting) 600 900 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. The error is not displayed when a fixed frequency is set. 59 UMG 96RM-E Energy meter Reset energy meter (Addr. 507) The UMG 96RM-E has power meters for active energy, reactive energy and apparent energy. The real, apparent and reactive energy meters can only be reset simultaneously. Set "001" for address 507 to reset the energy meter. Active energy reading Total active energy The active energy given in this example is 12 345 678 kWh C C The active energy given in this example is 134 178 kWh 60 Prior to commissioning potential production dependant contents of the energy counter, min/max values and records have to be deleted. If you reset the energy meter, the data will be lost. To avoid data loss, you should read and save the measured values before deletion using the GridVis software. UMG 96RM-E Harmonics Total harmonic distortion THD Harmonics are integer multiples of a fundamental oscillation. The fundamental oscillation of the voltage for UMG 96RM-E must range between 45 and 65Hz. The calculated harmonic voltages and currents relate to this fundamental oscillation. Harmonics up to 40 times the fundamental frequency are detected. THD is the ratio of the rms value of the harmonics to the rms value of the fundamental oscillation. The harmonics of the currents and of the voltages are displayed in amperes and volts, respectively.

There are two ways to retrieve the measurement readings: Setting range : 0 .. 60 seconds If 0 seconds are set, the measured value indications selected will not be rotated. The rotation time set applies to all display rotation profiles. • The automatically changing indication of the selected measurement readings is referred to herein as measured value rotation. • Press button 1 and 2 to select measured value indication from a pre-selected display profile. Both methods are available simultaneously. The measured value rotation is enabled when at least one measured value indication change time is over 0 seconds. Press a button to scroll the measured value indications of selected display profile. If no button is pressed for about 60 seconds, the device will switch to the measured value rotation to display the programmed measured value indications from the selected rotation profile in succession. 62 Display rotation profile (Addr. 038) Setting range: 0 .. 3 0 - Display rotation profile 1, pre-programmed. 1 - Display rotation profile 2, pre-programmed. 2 - Display rotation profile 3, pre-programmed. 3 - Display rotation profile, customizable. Measured value indocations Following a power resumption, the UMG 96RM-E displays the first measurement value table in the current display profile. To keep the selection to a manageable size, only a fraction of the available measurement values was preprogrammed in the factory for retrieval in the measured value display. Select another display profile to view other measured values on the UMG 96RM-E display. UMG 96RM-E Display profile (Addr. 037) Setting range: 0 .. 3 0 - Display profile 1, default value. 1 - Display profile 2, default value. 2 - Display profile 3, default value. 3 - Display profile, customizable. C C The customizable profiles (display rotation profile and display profile) can only be programmed using the GridVis software. Profile setting Both profiles (display rotation profile and display profile) are illustrated in the GridVis software included in the delivery package. The profiles can be adjusted using the Device Configuration function of the software; customizable display profiles are programmed individually. A connection between the UMG 96RM-E and the PC via an interface is required for the use of the GridVis software Fig. Profile setting in the GridVis software. 63 UMG 96RM-E 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. 0 = very bright 9 = 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 Fig. Indication of the supply frequency (50.0) and the phase sequence. 64 Fig. Rotary field direction can not be determined. UMG 96RM-E 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. Addr.

The operating period is measured and displayed in hours with a resolution of 0.1 h. The operating hours meter cannot be reset. The serial number displayed by the UMG 96RM-E consists of 6 digits and is a part of the serial number given on the rating plate. The serial number cannot be changed. Serial number 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. Fig. Measured value indications Operating hours meter The UMG 96RM-E operating hours meter reading is 140.8h. This corresponds to 140 hours and 80 industrial minutes. 100 industrial minutes = 60 minutes. In this example, 80 industrial minutes = 48 minutes. 66 The serial number is on the rating plate: XX00-0000 Software release (Addr. 750) The UMG 96RM-E software is continuously improved and extended. The software status in the device is identified with a 3 digit number, the software release. The software release cannot be changed by the user. UMG 96RM-E “Drag indicator” Max. value of the mean value over n minutes The “drag indicator” describes a maximum mean value of a measured value over a defined period. The period duration is set via a parameter, via the GridVis software or via the digital input 1. In the process, synchronisation is triggered via the internal clock (which can be set via parameter 206 or to a full hour) or optionally via digital input 1. If synchronisation via the digital input is selected, the capture time must be set! The thee highest values of 15 variables with time stamp are saved. The maximum values of the variables can also be viewed in the device display. Variables: • Current in the single phases L1.. L3 • Effective power (consumption/export) in the single phases L1.. L3 • Effective power (consumption/export), total. • Apparent power the single phases L1...L3 • Apparent power, total C Please note that even before averaging, the values are divided between positive and negative ones! During totalisation, first the totals for the single phases are calculated, then divided into positive and negative values! The maximum values are reset via the “Delete min./max. values” function with the GridVis program, via Modbus or on the display by setting the corresponding parameters (parameter 506: set from 0 to 1).

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. m 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: m The failure monitoring is only available from firmware-ver. 202 and hardware-release 104! m Monitoring of the connection to the residual current transformer is only available in AC mode!

The alarm bit must be reset or acknowledged manually. Failure monitoring Connection error to the transformer UMG 96RM-E 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. 73 UMG 96RM-E RS485 interface The MODBUS RTU protocol with CRC check on the RS485 interface can be used to access the data from the parameter and the measured value lists.

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. Fig.: Software GridVis, configuration menu 78 UMG 96RM-E 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. Pulse length 10ms .. 10s Pulse interval >10ms The values in the table are based on the minimum pulse length and the minimum pulse interval for the maximum number of pulses per hour.

C Pulse interval The pulse interval is proportional to the power output within the selected settings. C Measured value selection When programming with GridVis you have a selection of work values which are derived from the power output values. 79 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. Pulse value = C C 80 max. connected load max. number of pulses/h [Pulse/Wh] Since the active energy meter operates with a backstop, pulses will only be generated when drawing electricity. Since the reactive energy meter operates with a backstop, pulses will only be generated with inductive load applied. UMG 96RM-E Determine the pulse value External 230V AC operating voltage 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 UMG96RM generates a maximum number of 60,000 pulses (see Table "maximum number of pulses" per hour. Determining the maximum connected load Example: Current transformer = 150/5A Voltage L-N = max. 300 V Power per phase Power at 3 phases Max. connected load = 150 A x 300 V = 45 kW = 45kW x 3 = 135kW 24V DC + UMG 96RM-E - Switch and pulse outputs 13 +24V= Data logger 14 1.5k 15 Fig.: Connection example for the circuit as pulse output.

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 82 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.
