  • Page 33: Preparation

    ELR 10000 4U Series 2.3.2 Preparation Mains connection is done via the included 5 pole plug and on the back of the device. Wiring of the plug is at least 4 wire (3x L, PE) of suitable cross section and length. Full configuration with all phases, PE and N is permissible. For recommendations for a cable cross section see “2.3.4. Connection to AC supply”. Dimensioning of the DC wiring to the source has to reflect the following: • The cable cross section should always be specified for at least the maximum current of the device. • Continuous operation at the approved limit generates heat which must be removed, as well as voltage loss which depends on cable length and heating.

  • Page 34: Connection To Ac Supply

    ELR 10000 4U Series 2.3.4 Connection to AC supply • Connection to an AC supply must only be carried out by qualified personnel and the device must always be run directly on a power grid (transformer are permitted) and not on generators or UPS equipment! • Cable cross section must be suitable for the maximum input current of the device! See tables below. The device should furthermore be fused externally and according to the current rating and cable cross section • Before plugging the AC plug ensure that the device is switched off by its mains switch!

  • Page 36 ELR 10000 4U Series 2.3.4.3 Installation concept for energy recovering devices An ELR 10000 device converts the consumed DC energy into AC and feeds it back into the local power grid. The generated current adds to the grid current (see schematic below) and this can lead to an overload of the existing electrics installation. Considering any two outlets, no matter of what kind they are, there is usually no extra fusing installed in between. In case of a defect in the AC part (i.e. short-circuit) of any consumer device or when there are...

  • Page 43: Alarm Conditions

    ELR 10000 4U Series Alarm conditions This section only gives an overview about device alarms. What to do in case your device indi- cates an alarm condition is described in section “3.6. Alarms and monitoring”. As a basic principle, all alarm conditions are signaled optically (text + message in the display) and acoustically (if activated), as well as status via digital interface. In addition, the alarms are reported as signals on the analog interface. For later acquisition, an alarm counter can also be shown on display or read via digital interface.

  • Page 52: Adjustment Limits

    ELR 10000 4U Series 3.4.4 Adjustment limits Adjustment limits are only effective on the related set values, no matter if using manual adjust- ment or remote control setting! Defaults are that all set values (U, I, P, R) are adjustable from 0 to 102%. The full range may be obstructive in some cases, espe- cially for protection of applications against overvoltage. Therefore upper and lower limits for current (I) and voltage (U) can be set separately, which then limit the range of the adjustable set values. For power (P) and resistance (R) only upper value limits can be set.

    ELR 10000 4U Series Remote control 3.5.1 General Remote control is possible via one of the built-in interfaces (analog, USB, Ethernet) or via one of the optional in- terface modules. Important here is that only the analog or one digital interface can be in control. One of the digital ones is the master-slave bus. It means that if an attempt was made to switch to remote control via the digital interface whilst analog remote control is active (pin REMOTE = LOW) the device would report an error via the digital interface. In the opposite...

  • Page 66: Loading And Saving User Profiles

    ELR 10000 4U Series Loading and saving user profiles The menu “Profiles” serves to select between a default profile and up to 5 user profiles. A profile is a collection of all settings and set values. Upon delivery or after a factory reset all 6 profiles have the same settings and all set values are 0. Values adjusted on the main screen or anywhere else belong to a working profile which can be saved to one of the 5 user profiles. These user profiles or the default profile can then be switched. The default profile is read-only. The purpose of a profile is to load a set of set values, settings limits and monitoring thresholds quickly without having to readjust these. As all HMI settings are saved in the profile, including language, a profile change can also be accompanied by a change in HMI language. On calling up the menu page and selecting a profile the most important settings can be seen, but not changed. ► How to save the current values and settings as a user profile: While the DC input is switched off, tap touch area on the main screen.

  • Page 72: Arbitrary Function

    ELR 10000 4U Series 3.10.10 Arbitrary function The arbitrary (freely definable) function or function generator offers the user a wider scope of options. There are 99 curve segments (here: sequence points) available for use on either current (I) or voltage (U), all of which have the same set of parameters but can be differently configured, so that a complex function curve can be “constructed”. An arbitrary number out of the 99 sequence points can run in a sequence point block and this block can then be repeated up to 999 times or infinitely. Since the function must be assigned to either current or voltage, mix assign- ments of sequence point to both isn’t possible.
  • Page 73 ELR 10000 4U Series Schematic diagram: Applications and results: Example 2 Focusing 1 cycle of 1 sequence point: The DC values at start and end are the same but those of the am- plitude aren’t. The end value is higher than the start value so the amplitude increases with each new half sine wave continuously over the sequence point time.
  • Page 74 ELR 10000 4U Series By linking together a number of differently configured sequence points, complex progressions can be created. Smart configuration of the arbitrary generator can be used to match triangular, sine, rectangular or trapezoidal wave func- tions and thus, e.g. a sequence of rectangular waves with differing amplitudes or duty cycles could be produced. Schematic diagram: Applications and results: Example 7 Focusing 2 cycles of 1 sequence point: One sequence point, configured as in example 3, is run. Since the settings define that the end offset (DC) is higher than the start, the second run will revert to the same start level as the first, regardless of the signal level at the end of the first run. This can produce a discontinuity in the total progression (marked in red) which may only be compensated with a careful choice of settings.

Once the MPP is found, the function won’t stop, but try to track the MPP permanently. Due to the nature of solar panels this can only be done below the level of the MPP. As soon as this point is reached, the voltage starts to sink further and so does the actual power. The additional parameter ΔP defines how much the power may fall before the direction is reversed and the voltage starts to rise again until the load reaches the MPP. The result are...

See section 1.9.6.5 for the naming convention. Contrary to manual adjustment where you can define and use an arbitrary num- ber of points, loading from USB requires the CSV file to always contain the full number of points (100), because it can’t define which one is start and end. However, the on-screen setting for Start and End point remain valid. It means, if you actually want to use all 100 points from your loaded curve, you must set the parameters according.

The external documentation “Programming Guide ModBus & SCPI” on the included USB stick explains the approach. In general the following items apply: • The function generator isn’t directly controllable via the analog interface; the only impact to the function run can come from pin REM-SB switching the DC input off and on, which will also stop and restart the function • The function generator is unavailable if R mode (resistance) is activated...

  • Page 84: Other Applications

    ELR 10000 4U Series 3.11 Other applications 3.11.1 Parallel operation in master-slave (MS) Multiple devices of same kind and model can be connected in parallel in order to create a system with higher total current and hence higher power. For parallel operation in master-slave mode the units are usually connected on their DC inputs, their Share bus ports and their master-slave bus ports. This bus is digital and makes the system work as one big unit regarding value adjustment, readings and all further control. The Share bus is intended to balance the units dynamically in their voltage and also thus current on the DC input, especially if the master unit runs a dynamic function.
  • Page 85 ELR 10000 4U Series A max. of 64 units can be connected via Share bus. 3.11.1.4 Wiring and set-up of the digital master-slave bus The master-slave connectors are built-in and can be connected via network cables (≥CAT3, patch cable). After this, MS can be configured manually or by remote control. The following applies: • A maximum of 64 units can be connected via the bus: 1 master and up to 63 slaves.

Swipe up to find group “Master-slave” and tap it. Tapping on the blue button text next to Mode will open a selector. By selecting Master, if not already set, the master-slave mode is activated and the device is defined as master.

  • Page 87: Series Connection

    ELR 10000 4U Series 3.11.1.7 Alarms and other problem situations Master-slave operation, due to the connection of multiple units and their interaction, can cause additional problem situations which do not occur when operating individual units. For such occurrences the following regulations have been defined: • Generally, if the master loses connection to any slave, it will generate an MSP (master-slave protection) alarm, pop up a message on the screen and switch off its DC input. The slaves will fall back to single operation mode and also switch off their DC input. The MSP alarm can be deleted by initializing the master-slave system again. This can be done either in the MSP alarm pop-up screen or in the MENU of the master or via remote control. Alternatively, the alarm is also cleared by deactivating master-slave on the master unit • If one or more slave units are cut from AC supply (power switch, blackout, supply undervoltage) and come back later, they’re not automatically initialized and included again in the MS system. Then the init has to be repeated. • If the master unit is cut from AC supply (power switch, blackout) and comes back later, the unit will automati- cally initialize the MS system again, finding and integrating all active slaves. In this case, MS can be restored automatically.
