  • Page 3: Receipt Control

    Receipt control In order to ensure a perfect and safe use of the device, a proper transport, expert storage, erection and mounting and careful usage and maintenance are required. When it may be supposed, that a safe operation is no longer possible, the device has to be put out of service and be protected against unintentional putting into service.

  • Page 4: Product Description

    Product description Intended use The UMG96 is suited for fixed mounting and the measurement of voltage, current, power etc. in low voltage switchgear. The measurement is designed for 3 phase systems with neutral conductor (TN and TT-mains). Measurement and supply voltages (50Hz/60Hz) up to 275VAC against earth and 476VAC phase to phase can be connected directly.

  • Page 5: Hints For Maintenance

    Hints for Maintenance Before delivery the device is tested in various safety checks and marked with a seal. If the device is opened, these checks must be repeated. Attention! The guarantee is void if the seals are broken. Repairs and calibration Repairs and calibration can only be carried out by the manufacturing.

  • Page 6: Installation

    Installation Mounting place The UMG96 is suitable for a fixed installation into low and medium voltage switchgear. Any mounting position is possible. Measurement and supply voltage The measurement is laid out for three phase systems with neutral conductor (TN and TT mains). The measure- ment and supply voltages must be connected to the UMG 96 via a separation (switch or power switch) and an overcurrent protection (2-10A) within the building installation.The connection of the measurement and supply voltages is carried out at the back side of the UMG 96 via shock protected spring clamps.

  • Page 8: Installation And Putting Into Service

    Installation and putting into service The installation and putting into service of the UMG96 should be carried out as follows: - Mount the device - Connect measurement and supply voltage Before connection of the measurement and supply voltage to UMG96, please ensure, that the net conditions match the information on type plate.

  • Page 9: Check Phase Assignment

    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 indicated current in the corresponding phase decreases to 0A at the UMG96. Check current flow Short circuit two current transformers on the secondary.

  • Page 12: Usage And Display

    Usage and display The usage of the UMG 96 is carried out via the keys one and two. Measured values and programming data are indicated on the liquid crystal display. You must distinguish between Indication mode and Programming mode. By entering a password, you can avoid unintentional change of programming data. Indication mode In indication mode you can scroll through the programmed measured value indications by using the keys 1 and 2.

  • Page 16: Password

    Password To avoid an unintentional change of programming data, a user pass- word can be entered. If the correct user password is entered, a change into the following programming menus is possible. In delivery condition, no user password is given (000). In this case, the user password is skipped and you reach the current transformer menu immediately.

  • Page 18: Outputs K1 And K2

    Outputs K1 and K2 The UMG96 has got two outputs. Each output can either be used as a switching output or pulse output. The presetting for the outputs is: Output 1 = Pulse output for real energy Output 2 = Pulse output for reactive energy Outputs, which are assigned to a energy, energy as a pulse output.

  • Page 19: Usage As Switching Output

    Usage as switching output Exceeding Limit If a measured value, but not energy, is assigned to the outputs K1 or K2, the output energys as a switching output. The following values for programming are at your disposal: Limit Decimal point Measured value Sign Exceeding / underscoring...

  • Page 20: Usage As Pulse Output

    Usage as pulse output Pulse valency=100VArh/pulse If real energy is assigned to output K1 or reactive energy to K2, the respective output energys as a pulse output. For each pulse output, a pulse valency can be defined (Wh/pulse, VArh/pulse). The pulses, sampled within one second, are given out with a minimum duration VArh of 50ms and a maximum frequency of 10Hz.

  • Page 21: Pulse Valency

    Pulse valency The pulse valency is given in Wh per pulse. Pulse valency = Energy per pulse The pulse valency may not be confused with the kW-meter-constant. The kW-meter-constant is given in kW-meter-constant = Rotations per kWh The context between pulse valency and kW-meter- constant can be seen in the following correlations: kW-meter-constant = 1/pulse valency Pulse valency = 1/kW-meter-constant...

  • Page 22: Minimum Pulse Width

    Minimum pulse width If one of the outputs K1 or K2 is used as pulse output, a programmable minimum pulse width is assigned. The minimum pul- MkWh se width cannot be set separately for the outputs K1 and K2, but is MkVArh valid for both pulse outputs.

  • Page 23: Averaging Times (Bimetal Function)

    Averaging times (Bimetal function) For the most current and power values, a mean value is built. You can Symbol for mean value program a common averaging time for the current measured values L1, L2, L3 and N , and one for power measured values, real power, apparent power and reactive power is programmable.

  • Page 24: Measured Value Rotation

    Measured value rotation Rotation time in seconds Once in a second all measured values are calculated and can be shown on the display. For calling up the measured value indications, two methods are available: - The automatic rotating indications of selected measured value indications, in the following called measured value rotation.

  • Page 25: Measured Value Selection

    Measured value selection In programming menu „measured value selection“, the measured value indications can be selected via the two keys for automatic rota- tion. All listed measured values from table 1 can be called up via the keys 1 and 2, when the device is delivered. The selection for automatic rotation is programmed together with the value selection.

  • Page 26: Delete Minimum And Maximum Values

    Delete minimum and maximum values In programming mode, the menu „delete minimum and maximum values“ is marked with an arrow up- and downwards. All minimum and maximum values can only be deleted simultaneously. One exception is the maximum value of current mean value. The maximum value of current mean value can be deleted directly in in- dication menu by pressing key 2 for a long time.

  • Page 27: Lcd Contrast

    LCD contrast The favoured view for the LCD display is from below. This favoured view can be adapted by the user. The contrast setting is possible in steps from 0 to 15. 0 = Very light 15 = Very dark In order to achieve an optimum contrast over the whole temperature range, the inner temperature of the device is measured and the contrast setting is corrected automatically.
