UMG 96RM-P/-CBM

Current measurement via I1 to I4

The UMG 96RM-P/-CBM is designed to have current transformers with secondary currents from ../1A and ../5A attached cia terminals I1-I4. The factory default for the current transformer ratio is 5/5A and must be adapted to the current transformer employed if necessary. Direct measurement without a current transformer is not possible using the UMG 96RM-P/-CBM. Only AC currents can be measured - DC currents cannot.

Via the current measurement input I4 only an apparent current measurement is carried out thanks to the lack of a multiplier. Power measurements are therefore not possible using the I4 input.

Load

Fig. Current measurement (I1-I3) via current transformers (connection example)

Caution!

The current measurement inputs are dangerous to touch.

The attached screw terminal has to be ﬁxed sufﬁciently with two screws on the device!

UMG 96RM-P/-CBM

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

Fig. Current measurement (I4) via current transformer (connection example)

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.

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 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.

Proﬁbus interface (only UMG 96RM-P)

This 9-pin D-sub receptacle RS485 interface supports the Proﬁbus DP V0 slave protocol.

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)

Connection of the bus wiring

UMG 96RM-P/-CBM

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). With the switch set to ON terminals 2A and 2B are switched off for further continuing bus wiring.

Digital outputs

The UMG 96RM-P and UMG 96RM-CBM have 6 digital outputs, whereby these are split into two groups of 2 and 4 outputs (see illustration on the right).

These outputs are electrically isolated from the evaluation electronics by optocouplers. The digital outputs have a common reference.

• The digital outputs can switch DC and AC loads.

• The digital outputs are not short circuit protected.

• Connected cables longer than 30 m must be shielded.

• An external auxiliary voltage is required.

• The digital outputs can be used as pulse outputs.

• The digital outputs can be controlled via the Modbus.

• The digital outputs can output results from comparators.

digital/pulse outputs

When using the digital outputs as pulse outputs the auxiliary voltage (DC) must have a max. residual ripple of 5%.

Functions for the digital outputs can be adjusted clearly in the GridVis software provided in the scope of deliverables. A connection between the UMG 96RM-P/

-CBM and the PC via an interface is required for the use of the GridVis software.

Operation

The UMG 96RM-P/-CBM is operated using buttons 1 and 2. Measured values and programming data appears on a liquid crystal display.

A distinction is made between display mode and pro- gramming mode. The accidental changing of programming data is prevented by the entry of a password.

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

programmed, the user arrives directly in the ﬁrst programming menu. Programming mode is indicated by the text “PRG” on the display.

Button 2 can now be used to switch between the following programming menus:

- 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.

Parameters and measured values

All parameters necessary for operating the UMG 96RM-P/-CBM, e.g. the current transformer data, and a selection of frequently required measured values are stored in the table. The contents of most addresses can be accessed via the serial interface and the buttons on the UMG 96RMP/-CBM.

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.

Example of the parameter display

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.

Conﬁguration

Applying the supply voltage

To conﬁgure the UMG 96RM-P/-CBM, the supply voltage must be connected.

The level of supply voltage for the UMG 96RM-P/-CBM can be found on the nameplate.

If no display appears, check the operating voltage to determine whether it is within the rated voltage range.

Current and voltage transformers

A current transformer is set to 5/5 A in the factory. The pre-programmed voltage transformer ratio only needs to be changed if voltage transformers are connected.

When connecting voltage transformers, the measurement voltage on the UMG 96RM-P/-CBM nameplate must be observed!

Attention!

Supply voltages that do not correspond to the nameplate information can lead to device malfunction or destruction.

The adjustable value 0 for the primary current transformer does not produce any useful energy values and must not be used.

Devices, which are programmed to automatic frequency detection, need approximately 20 seconds to detect grid frequency. During this period, the measured values do not keep the conﬁrmed measuring accuracy.

UMG 96RM-P/-CBM

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)

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.

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.

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.

Setting Baud rate

0 9.6 kbps 1 19.2 kbps 2 38.4 kbps 3 57.6 kbps 4 115.2 kbps (factory setting)

Mean value

Mean values are formed over an adjustable period for the current, voltage and power measured values. The mean values are identiﬁed with a bar above the measured value. The averaging time can be selected from a list of nine ﬁxed averaging times.

Current averaging time (addr. 040) Power averaging time (addr. 041) Voltage averaging time (addr. 042)

Setting Averaging time/sec.

UMG 96RM-P/-CBM

Averaging method

After the set averaging time, the exponential averaging method used achieves at least 95% of the measured value.

Minimum and maximum values

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.

Mains frequency (addr. 034)

UMG 96RM-P/-CBM

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.

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.

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.

UMG 96RM-P/-CBM

Measured value relay

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:

• 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.

Changeover time (addr. 039)

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.

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.

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.

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.

UMG 96RM-P/-CBM

User password (addr. 050)

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.

If a user password was programmed, the password menu will appear with the display "000". The ﬁrst digit of the user password ﬂashes and can be changed with button 2. The next digit is selected by pressing button 1 and will begin ﬂashing. The programming menu for the current transformer can only be accessed after entering the correct number combination.

Forgotten password

If you have forgotten the password, the password can 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.

Clear energy meter (addr. 507)

The active, apparent and reactive energy meters can only be cleared together.

Address 507 must be written with "001" in order to clear the contents of the energy meters.

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

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.

LCD contrast (addr. 035)

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

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.

Time recording

The UMG 96RM-P/-CBM records the operating hours and the total running time of each comparator

• where the time of operating hours is measured with a resolution of 0.1 h and is displayed in hours or

• the total running time of the comparator is represented in seconds (when 999999 seconds is reached, the display changes to hours).

For the querying of measured value displays, the times are marked with the numbers 1 to 6:

none = operating hours meter 1 = total running time, comparator 1A 2 = total running time, comparator 2A 3 = total running time, comparator 1B 4 = total running time, comparator 2B 5 = total running time, comparator 1C 6 = total running time, comparator 2C

A maximum of 99999.9 h (= 11.4 years) can be shown on the measured value display.

UMG 96RM-P/-CBM

Operating hours meter

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.

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 (addr. 754)

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.

Commissioning

Applying the supply voltage

• The level of supply voltage for the UMG 96RM-P/

-CBM can be found on the nameplate.

• After applying the supply voltage, the UMG 96RM-P/

-CBM switches to the ﬁrst measured value display.

• If no display appears, the supply voltage must be checked to determine whether it is in the rated voltage range.

Applying the measured voltage

• Voltage measurements in networks with rated voltages above 300V AC to ground must be connected to a voltage transformer.

• After the measured voltages are connected, the measured values for the L-N and L-L voltages displayed by the UMG 96RM-P/-CBM must match those at the voltage measurement input.

Attention!

Voltages and currents outside the permissible metering range can result in personal injury and damage to the device.

Applying the measured current

The UMG 96RM-P/-CBM is designed for connecting ../1 A and ../5 A current transformers. Only AC currents and not DC currents can be measured via the current measurement inputs. Short circuit all current transformer outputs except for one. Compare the currents displayed on the UMG 96RMP/-CBM with the applied current. The current displayed by the UMG 96RM-P/-CBM must match the input current, taking the current transformer ratio into consideration. In the short circuit current measurement inputs, the UMG 96RM-P/-CBM must show approx. zero amperes.

The factory-set current transformer ratio is 5/5 A and may need to be adapted to the current transformer used.

Attention!

Supply voltages that do not correspond to the nameplate information can lead to device malfunction or destruction.

Attention!

The UMG 96RM-P/-CBM is not suitable for the measurement of DC voltages.

UMG 96RM-P/-CBM

Rotation ﬁeld direction

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.

Checking the phase assignment

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.

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.

Checking the measurement

If all voltage and current measurement inputs are correctly connected, the individual and sum power ratings are accurately calculated and displayed.

Checking the individual power ratings

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.

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.

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.

UMG 96RM-P/-CBM

Proﬁbus interface (only UMG 96RM-P)

Proﬁbus proﬁles

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.

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.

Activate outputs/tariffs via Proﬁbus

To set the outputs or the tariffs an appropriate proﬁle must be selected. Alongside the 1st byte used for the proﬁle selection three further bytes can be used to:

• 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.

Example: Proﬁle number 8 selected (Binary representation)

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:

07060

5 4

UMG 96RM-P/-CBM

Example: Output 1-3 set

Unused Unused Digital output 6 Digital output 5 Digital output 4 Digital output 3 Digital output 2 Digital output 1

Control tariffs (3rd byte):

Setting or clearing the bits enables the selection of tariffs 1-7. 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)

Bit:

07060

7 6

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.

Example: Apparent energy selected

Unused Energy meter for apparent energy Energy meter for reactive energy (cap.) Energy meter for reactive energy (ind.) Energy meter for reactive energy Energy meter for active energy (delivered) Energy meter for active energy (drawn) Energy meter for active energy (without backstop)

Bit:

UMG 96RM-P/-CBM

Deactivate energy meters / tariffs via Proﬁbus

If energy meters are assigned to a tariff then these can be deactivated via byte 3 and byte 4 (cf. activate tariffs via Proﬁbus). Here the selection of the desired tariff is implemented in byte 3 and the clearing of the associated bits in byte 4 deactivates the energy meter.

Example: If the energy meter for active energy (drawn) is set under tariff 3, the deactivation of the energy meter is implemented as follows:

Byte 3: Tariff 3 selected

Bit:

7 6

Byte 4: Deactivating energy meters

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.

Bit:

7 6

Reading out measurement values via the Proﬁbus

Selected measurement values can be read out via 4 factory-set proﬁles and an additional 8 userdeﬁned proﬁles. Here each proﬁle has a unique proﬁle number with which a PLC can read out the conﬁgured measurement values of a proﬁle.

Example: Reading out of measurement values from the factorypreconﬁgured Proﬁbus proﬁle number 8.

The 1st byte should be set to the proﬁle number 8 (dec.) and sent to the UMG 96RM-P. The UMG 96RM-P then delivers the proﬁle number 8 and the measured values set in proﬁle 8 back.

Bit:

Byte 1: Proﬁle number 8 selection

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

Pulse length (addr. 106)

UMG 96RM-P/-CBM

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

The typical pulse length for S0 pulses is 30 ms.

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.

Measured value selection

When programming with GridVis, a selection of energy values that are derived from the power values is received.

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.

Determining the pulse value

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:

Error Description of the error 0x01 EEPROM does not answer. 0x02 Address range exceeded. 0x04 Checksum error. 0x08 Error in the internal I2C bus.

Clock/battery errors

Clock or battery errors are displayed together with the „EEE“ symbol followed by „bAt“ and a status number. For a more detailed description please refer to „Baterry control function“ and „Replacing the battery“.

Overranges

Overranges are displayed as long as they exist and cannot be acknowledged. An overrange exists if at least one of the voltage or current measurement inputs lies outside their speciﬁed measuring range.

The "upwards" arrow indicates the phase where the overrrange occured. The appropriate error message for current path I4 is generated as shown below. The “V” and “A” symbols indicate whether the overrange occurred in the current or in the voltage path.

A = current path V = voltage path

Indication of the phase (L1/L2/ L3) with overrange. The current phase l4 overranges occur as shown in the ﬁgure below.

Overrange limits:

I = 7 Aeff UL-N = 520 VL-N

Examples

A = current path
