  • Page 30: Preparation

    Preparation Mains connection of an energy back-feeding electronic load of ELR 9000 HP series is done via the included 5 pole plug on the back of the device. Wiring of the plug is at least 3 strand or, for some models, 4 strand of suitable cross section and length.

  • Page 31: Mains Connection (Ac)

    ELR 9000 HP Series 2.3.4 Mains connection (AC) • Connection to an AC mains supply may only be carried out by qualified personnel! • Cable cross section must be suitable for the maximum input/output current of the device (see table below)! • Before plugging in the input plug ensure that the device is switched off by its mains switch!
  • Page 32 The scheme below depicts an often unconsidered problem: the current load of the local electric installation. The devices of series ELR 9000 HP recover energy and feed it back to the local or public grid. The recovered current then adds to the grid current and this can lead to an overload of the existing installation. Considering any two connection points, no matter of what kind, there is usually no extra fusing installed.

  • Page 51: Adjustment Limits

    Changing the operating mode In general, the manual operation of an ELR 9000 HP distinguishes between three operating modes (U/I, P/I, R/I) which are tied to set value input using the rotary knobs or ten-key pad: This assignment must be changed if one of the four set values is to be adjusted which is currently not available.

  • Page 52: Manual Adjustment Of Set Values

    ELR 9000 HP Series 3.4.6 Manual adjustment of set values The set values for voltage, current, power and resistance are the fundamental operating possibilities of an elec- tronic load and hence the two rotary knobs on the front of the device are always assigned to two of the four values in manual operation.

  • Page 60: Alarms And Monitoring

    ELR 9000 HP Series Alarms and monitoring 3.6.1 Definition of terms There is a clear distinction between device alarms (see „3.3. Alarm conditions“), such as overvoltage protection, and user defined events such as OCD (overcurrent detection). Whilst device alarms primarily serve to protect the connected DC source by switching the DC input off, user defined events can do the same (action = ALARM), but can also simply give an acoustic signal to make the user aware.
  • Page 61 ELR 9000 HP Series Some device alarms are configurable: Alarm Meaning Description Range Indication OverVoltage Triggers an alarm if the DC input voltage reaches the Display, analog 0 V...1.1*U Protection defined threshold. The DC input will be switched off. IF, digital IF...
  • Page 62 ELR 9000 HP Series 3.6.2.1 User defined events The monitoring functions of the device can be configured for user defined events. By default, events are deactivated (action = NONE). Contrary to device alarms, the events only work while the DC input is switched on. It means, for instance, that you cannot detect undervoltage (UVD) anymore after switching the DC input off and the voltage is still sinking.

    ELR 9000 HP Series 3.10.10 Arbitrary function The arbitrary (freely definable) function offers the user further scope. There are 99 sequence points available for use on current I or voltage U, all of which have the same parameters but which can be differently configured so that a complex function process can be built up.

The end value is higher than the start so that the amplitude increases with each new half sine wave continuously through the sequence.
  • Page 72 ELR 9000 HP 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 functions and thus, e.g. a curve of rectangular waves with differing amplitudes or duty cycles could be produced.

  • Page 81: Other Applications

    This can be done using the standard models with display and control panel or the new slave models (ELR 9000 HP Slave, available from mid 2018). These models are intended to run as slave only and thus have no display and cheaper. Only disadvantage: the slave models are only available as 15 kW versions, so they only match the 15 kW standard models.

    ELR 9000 HP Series • Loss of connection to any slave will result in shutdown of all DC inputs, as a safety measure, and the master will report this situation in the display with a pop-up “Master-slave safety mode”. Then the MS system has to be re-initialised, either with or without re-establishing connection to the disconnected unit(s) before.

    (see section „1.9.10. Share connector“) and a sink, in this case a series ELR 9000 HP electronic load. The source and the sink function alternately in order to test a device, such as a battery, by deliberate charging and discharging as part of a functional test, or a motor by clipping excess energy with the sink.
  • Page 86 ELR 9000 HP Series 3.11.3.3 Settings on the devices The master-slave settings in the MENU also affect the Share bus. For correct 2QO operation, all involved load units must be slaves on the Share bus. This is achieved by setting the master-slave mode to OFF or SLAVE, de- pending on if there is digital master-slave in use or not.

    Contact the supplier in case of suspicion and elicit the steps to be taken. It will then usually be necessary to return the device to Elektro-Automatik (with or without warranty). If a return for checking or repair is to be carried out, ensure that: • the supplier has been contacted and it is clarified how and where the device should be sent.

  • Page 88: Calibration

    4.3.1 Preface The devices of series ELR 9000 HP feature a function to re-adjust the most important DC input related values, which can help in case these have moved out of tolerance. The readjustment is intended to compensate small deviations of up to 1% or 2% rated value. There are several reasons which could make it necessary to re-adjust a unit: component aging, component deterioration, extreme ambient conditions, high frequent use.
  • Page 89 ELR 9000 HP Series 4.3.3.1 Calibrating the set values ► How to calibrate the input voltage Adjust the connected voltage source to approx. 102% of the maximum voltage specified for the ELR device. For the example with an 80 V ELR this would be 81.6 V for the source.
