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. 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 24 N The attached screw terminal has to be fixed sufficiently with two screws on the device! m C 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. Caution! The UMG 96RM-P/-CBM is not suitable for measuring DC voltages. It is not necessary to configure a connection schematic for the I4 measurement input. Load c L2 UMG 96RM-P/-CBM Fig. Current measurement (I4) via current transformer (connection example) 25 UMG 96RM-P/-CBM Direction of the current The current direction can be individually corrected on the device or via the serial interfaces for each phase. In the case of incorrect connection, the current transformer does not need to be subsequently reconnected. c c c 26 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.

For the simple connection of inbound and outbound bus wiring these should be connected to the UNG 96RM-P via a Profibus connector. For the connection we recommend a 9-pin Profibus connector, e.g. type „SUBCON-Plus-ProfiB/AX/SC“ from Phoenix, item number 2744380. (Janitza item no:13.10.539) D-sub receptacle for Profibus C The device address can be configured by using the parameter 000 if the device is used in a Profibus-System. The baud rate in a Profibus system is detected automatically and must NOT be set via the address 001! Fig. UMG 96RM-P with D-sub receptacle for Profibus (View on rear). 37 UMG 96RM-P/-CBM Connection of the bus wiring The inbound bus wiring is connected to terminals 1A and 1B of the Profibus connector. The continuing bus wiring for the next device in line should be connected to terminals 2A and 2B. If there are no subsequent devices in the line then the bus wiring must be terminated with a resistor (switch to ON).

Measured values and programming data appears on a liquid crystal display. programmed, the user arrives directly in the first programming menu. Programming mode is indicated by the text “PRG” on the display. A distinction is made between display mode and programming mode. The accidental changing of programming data is prevented by the entry of a password. Button 2 can now be used to switch between the following programming menus: Display mode In the display mode, you can scroll between the programmed measured value displays using buttons 1 and 2. All factory-set measured value displays listed in section 1 can be called up. Up to three measured values are displayed per measured value display. The measured value relaying allows select measured value displays to be shown alternately after a settable changeover time. Programming mode In the programming mode, the settings required for operating the UMG 96RM-P/-CBM can be displayed and changed. Pressing buttons 1 and 2 simultaneously for about one second calls up the programming mode after the password prompt. If no user password was 46 - current transformer, - voltage transformer, - parameter list. If the device is in programming mode and no button has been pressed for approximately 60 seconds or if buttons 1 and 2 are pressed simultaneously for approx. one second, the UMG 96RM-P/-CBM returns to display mode.

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. 48 Example of the measured value display In this example, the UMG 96RM-P/-CBM display shows the voltages L to N with 230 V each.

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! 50 c C m C 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. Prior to commissioning potential production dependant contents of the energy counter, min/max values and records have to be deleted. UMG 96RM-P/-CBM C Current and voltage transformers The transformer ratios for each of the three current and voltage measurement inputs can be individually programmed in the GridVis software included in the scope of delivery. Only the transformer ratio of the respective group of current measurement inputs or voltage measurement inputs is adjustable on the device.

UMG 96RM-P/-CBM 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 for the current, voltage and power measured The mean values are identified with a bar the measured value. The averaging time can be selected from a list fixed averaging times. C Current averaging time (addr. 040) Power averaging time (addr. 041) Voltage averaging time (addr. 042) The adjustable range of the device address is between 0 and 255. The values 0 and 248 to 255 are reserved and may not be used. Baud rate (addr. 001) A common baud rate is adjustable for the RS485 interfaces. The baud rate must be chosen to be a uniform value in the network. On address 003 the quantity of stop bits can be set (0=1bit, 1=2bits). Data bits (8) and parity (none) are permanently set.

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. 57 UMG 96RM-P/-CBM Energy meter Reading the active energy The UMG 96RM-P/-CBM has energy meters for active energy, reactive energy and apparent energy. Total active energy The active energy in this example is: 12 345 678 kWh The active energy in this example is: 134 178 kWh 58 UMG 96RM-P/-CBM Harmonics Total Harmonic Distortion (THD) Harmonics are the integer multiple of a mains frequency. The voltage mains frequency for the UMG 96RM-P/ -CBM must be in the range between 45 and 65 Hz. The calculated voltage and current harmonics refer to this mains frequency. Harmonics up to 40x the mains frequency are recorded. THD is the ratio of the root mean square value of harmonics to the root mean square value of the mains frequency. Total Harmonic Distortion of the current (THDI): The harmonics for currents are given in amperes and the harmonics for voltages are given in volts. Total Harmonic Distortion of the voltage (THDU): Number of the harmonic Phase L3 Current harmonic Value Fig. Display of the 15th harmonic of the current in the L3 phase (example). Phase L3 Voltage Value C Harmonics are not displayed in the factory default setting. Fig. Display of the total harmonic distortion of the voltage from the L3 phase (example). 59 UMG 96RM-P/-CBM Measured value relay Changeover time (addr. 039) All measured values are calculated every 10/12 periods and can be recalled once per second on the measured value displays. Two methods are available for retrieving the measured value displays: Adjustment range: 0 .. 60 seconds If 0 seconds are set, no changeover takes place between the measured value displays selected for the measured value relay. The changeover time applies for all display change profiles. • The automatically changing display of selected measured values, referred to here as measured value relaying. • Selection of a measured value display using buttons 1 and 2 from a preselected display profile. Both methods are simultaneously available. Measured value relaying is active if at least one measured value display is programmed with a changeover time greater than 0 seconds. If a button is pressed, the measured value displays of the selected display profile can be browsed. If no button is pressed for about 60 seconds, the device switches to the measured value relay and the measured values from the selected display change profile of the programmed measured value displays are shown one after the other. 60 Display change profile (addr. 038) Adjustment range: 0 .. 3 0 - Display changeover profile 1, by default. 1 - Display changeover profile 2, by default. 2 - Display changeover profile 3, by default. 3 - Customised display changeover profile. Measured value displays After return of the power supply, the UMG 96RM-P/ -CBM shows the first measured value panel from the current display profile. In order to keep the selection of measured values to be displayed arranged in a clear manner, only one part of the available measured values is pre-programmed for recall in the measured value display by default. A different display profile can be selected if other measured values are required to be shown on the UMG 96RM-P/-CBM display. UMG 96RM-P/-CBM Display profile (addr. 037) Adjustment range: 0 .. 3 0 - Display profile 1, default setting. 1 - Display profile 2, default setting. 2 - Display profile 3, default setting. 3 - Customised display profile. C Profile settings The profiles (display change profile and display profile) are clearly shown in the GridVis software included in the scope of delivery. The profiles can be adjusted in the software via the device configuration; customised display profiles can also be programmed. A connection between the UMG 96RM-P/ -CBM and the PC via the serial interface (RS485) is required for using the GridVis software. This requires an interface converter RS485/232, item no. 15.06.015 or RS485/ USB, item no. 15.06.025. C The customised profiles (display change profile and display profile) can only be programmed via the GridVis software. Fig. Display of the profile setting in the GridVis software. 61 UMG 96RM-P/-CBM User password (addr. 050) Clear energy meter (addr. 507) A user password can be programmed in order to impede any accidental change to programming data. A switch to the next programming menu can only be made after entering the correct user password. No user password is specified in the factory. In this case, the password menu is skipped and the current transformer menu is reached directly. The active, apparent and reactive energy meters can only be cleared together. 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. Address 507 must be written with "001" in order to clear the contents of the energy meters. C Forgotten password If you have forgotten the password, the password can only be cleared by using the GridVis PC software. To do this, connect the UMG 96RM-P/-CBM to the PC via a suitable interface. More information can be found in the help section of GridVis. 62 C Prior to commissioning potential production dependant contents of the energy counter, min/max values and records have to be deleted. Clearing the energy meters means this data in the device is gone. In order to avoid possible data loss, read and save the measured values with the GridVis software before clearing. 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 Fig. Display of the mains frequency (50.0) and the rotation field direction Fig. No rotation field direction detectable. 63 UMG 96RM-P/-CBM 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.

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. Fig. Operating hours meter of the measured value display The UMG 96RM-P/-CBM shows the number 140.8h in the operating hours meter. This corresponds to 140 hours and 80 industrial minutes. 100 industrial minutes correspond to 60 minutes. In this example, 80 industrial minutes therefore represent 48 minutes. Serial number display Serial number information on the nameplate: XX00-0000 Software release (addr. 750) The software for UMG 96RM-P/-CBM is continuously improved and expanded. The software version in the device is marked with a 3-digit number, the software release. The user cannot change the software release. 65 UMG 96RM-P/-CBM “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..

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. m 68 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. m m 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. 70 UMG 96RM-P/-CBM RS485 interface The data from the parameter and measured value list can be accessed via the MODBUS RTU protocol with CRC check to the RS485 interface.

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. 76 Example: Profile number 8 selected (Binary representation) Bit: 7 6 5 4 3 2 1 0 1 0 0 0 0 0 0 000 0 Switching digital outputs (2nd byte): Setting or clearing the bits in byte 2 ("Profibus remote" type) enables the setting of the digital outputs 1-6. Bits 6 and 7 are not used.

Bit 7 is not used. If several tariffs are set in the byte then the tariff with the least significant bit is selected. If byte 3 is used, then byte 4 should be set! Example: Tariff 3 selected Unused Tariff 7 (0=inactive, 1=active) Tariff 6 (0=inactive, 1=active) Tariff 5 (0=inactive, 1=active) Tariff 4 (0=inactive, 1=active) Tariff 3 (0=inactive, 1=active) Tariff 2 (0=inactive, 1=active) Tariff 1 (0=inactive, 1=active) Control tariffs (4th byte): Setting or clearing bits 0 to 6 of byte 4 enables a selection of energy meters for the tariff set. Each tariff can have up to 7 energy meters allocated to it. Bit: 7 6 5 4 3 2 1 0 Unused Energy meter for apparent energy Energy meter for reactive energy (cap.)

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: Byte 3: Tariff 3 selected Unused Tariff 7 (0=inactive, 1=active) Tariff 6 (0=inactive, 1=active) Tariff 5 (0=inactive, 1=active) Tariff 4 (0=inactive, 1=active) Tariff 3 (0=inactive, 1=active) Tariff 2 (0=inactive, 1=active) Tariff 1 (0=inactive, 1=active) 78 Bit: 7 6 5 4 3 2 1 0 1 0 0 0 0 0 0 0 0 0 0 00 0 Byte 4: Deactivating energy meters Bit: 7 6 5 4 3 2 1 0 Unused Energy meter for apparent energy Energy meter for reactive energy (cap.)

Energy meter for reactive energy Energy meter for active energy (delivered) Energy meter for active energy (drawn) Energy meter for active energy (without backstop) 0 0 0 0 0 0 0 0 0 0 0 00 0 The energy meter is deleted by selecting the tariff (byte 3) and clearing the bits in byte 4 associated with the energy meter. If the meter is deleted then a new energy meter can be assigned to the tariff. If the deactivation of a tariff is desired then the energy meters assigned should be deleted first via bytes 3 and 4 and then the tariff should be deactivated via byte 3. UMG 96RM-P/-CBM 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. C The device address can be configured by using the parameter 000 if the device is used in a Profibus-System. The baud rate in a Profibus system is detected automatically and must NOT be set via the address 001! 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. Byte 1: Profile number 8 selection Bit: 7 6 5 4 3 2 1 0 1 0 0 0 0 0 0 0 000 79 UMG 96RM-P/-CBM Example: Using Profibus to retrieve measurement values At least one Profibus profile must be set up with GridVis and transferred to the UMG 96RM-P.

The GSD file is required by the configuration program of the PLC. The device master file for the UMG 96RM-P has the filename „96RM0D44.GSD“ and is included on the data carrier as part of the scope of deliverables. The measuring values in the Profibus profile number 8 till 11 have the format „high byte before low byte“. For measurements values in the format „low byte before high byte“ must be added to the Profibus profile number 128! System variables Various system variables (measured values) are available in the formats Float and Integer (byte order: Big and Little Endian). These variables are clearly defined and listed in the Modbus address list. A customized scaling and conversion to other formats are not possible. In case that a different data type of a variable is required, an alternative representation of the variable (value) must exist (see Modbus address list). 81 UMG 96RM-P/-CBM Factory pre-configured profiles Profibus profile number 8 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Byte index 1 5 9 13 17 21 25 29 33 37 41 45 49 53 57 61 65 69 73 77 21 22 23 24 25 26 27 81 85 89 93 97 101 105 82 Value type Value format Effective voltage L1 Float Effective voltage L2 Float Effective voltage L3 Float Effective voltage L1-L2 Float Effective voltage L2-L3 Float Effective voltage L3-L1 Float Effective current L1 Float Effective current L2 Float Effective current L3 Float Effective current L4 Float Effective current sum L1..L3 Float Effective power L1 Float Effective power L2 Float Effective power L3 Float Cos phi (math.)

Digital output 1: Addr. 608 = 1 Digital output 2: Addr. 609 = 1 85 UMG 96RM-P/-CBM Impulse output The digital outputs can be used for the output of pulses for the computation of power consumption. 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 86 UMG 96RM-P/-CBM Pulse length (addr. 106) The pulse length applies for both pulse outputs and is permanently fixed via parameter address 106. Adjustment range: 1 .. 1000 1= 10ms Default: 5 = 50ms Due to the minimum pulse length and minimum pulse pause, the values in the table are for the maximum number of pulses per hour. Pulse length Pulse pause Maximum pulses/hour The typical pulse length for S0 pulses is 30 ms. 10 ms 10 ms 180,000 pulses/hour Pulse pause The pulse pause is at least as long as the selected pulse length. The pulse pause depends on the measured energy, for example, and can be hours or days. 30 ms 30 ms 60,000 pulses/hour 50 ms 50 ms 36,000 pulses/hour 100 ms 100 ms 18,000 pulses/hour 500 ms 500 ms 3,600 pulses/hour 1s 1s 1,800 pulses/hour 10 s 10 s 180 pulses/hour Pulse length 10 ms .. 10 s C Pulse pause >10 ms Pulse spacing The pulse spacing is proportional to the power within the selected setting. Examples for the maximum possible number of pulses per hour. C Measured value selection When programming with GridVis, a selection of energy values that are derived from the power values is received. 87 UMG 96RM-P/-CBM 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. Pulse value = C C 88 maximum connection power [pulse/Wh] maximum number of pulses per hour Since the active energy meter works with a return stop, pulses are only issued during import of electrical energy. Since the reactive energy meter works with a return stop, pulses are only issued under inductive load. UMG 96RM-P/-CBM Determining the pulse value External 230 V AC operating voltage Setting the pulse length Set the pulse length according to the requirements of the connected pulse receiver. For a pulse length of 30 ms, for example, the UMG 96RMP/-CBM can issue a maximum number of 60,000 pulses (see Table "Maximum Pulse Number") per hour. Determining the maximum connected load Example: Current transformer = 150/5 A L-N voltage = max. 300 V Power per phase = 150 A x 300 V = 45 kW Power for 3 phases = 45 kW x 3 Maximum connected load = 135 kW 24 V DC + UMG 96RM-P/-CBM - Switching and pulse outputs 13 +24V= Data logger 14 1.5 k 15 Fig.: Connection example for wiring the pulse output. Calculating the pulse value Pulse value = Pulse value Pulse value Pulse value maximum connection power [pulse/Wh] maximum number of pulses per hour = 135 kW / 60000 pulses/h = 0.00225 pulses/kWh = 2.25 pulses/Wh C When using the digital outputs as a pulse output, the auxiliary voltage (DC) must only have a maximum residual ripple of 5%. 89 UMG 96RM-P/-CBM Comparators and monitoring threshold values Six comparator groups (1 - 6) and three comparators per group (A – C) 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.

The permanently installed lithium battery must be disposed of separately. 92 We will need the following information from you to answer any questions: Device calibration The devices are calibrated by the manufacturer at the factory - it is not necessary to recalibrate the device providing that the environmental conditions are complied with. Calibration intervals It is recommended to have a new calibration carried out by the manufacturer or an accredited laboratory every 5 years approximately. UMG 96RM-P/-CBM 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). See chapter "Changing the battery" for more information. Abb.

Error cause Description of the error If there are warnings and serious errors, the error message is indicated by the symbol "EEE" followed by an error number. Symbol for an error message Example of error message 911: The error number is composed of serious error 910 and internal error cause 0x01. Error number The three-digit error number is composed of the error description and (if detectable by the UMG 96RM-P/-CBM) one or more error causes. 96 In this example, an error occurred when reading the calibration from the EEPROM. The device must be sent to the manufacturer for inspection. UMG 96RM-P/-CBM Warnings Internal causes of the error Warnings are less serious errors and can be acknowledged with buttons 1 or 2. The measured values continue to be recorded and displayed. This error is redisplayed after each voltage recovery. The UMG 96RM-P/-CBM can usually determine the cause of an internal error and then report it with the following error code. The device must be sent to the manufacturer for inspection. Error EEE 500 Description of the error The mains frequency could not be determined. Possible causes: The voltage at L1 is too small. The mains frequency does not range between 45 and 65Hz. Remedy: Check the mains frequency. Select fixed frequency on the device. Serious errors The device must be sent to the manufacturer for inspection.
