UMG 96RM-E Current measurement via I1 to I4 The UMG 96 RM-E 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-E. Only AC currents can be measured - DC currents cannot.
m Caution! The UMG 96RM-E is not suitable for measuring DC voltages. C It is not necessary to configure a connection schematic for the I4 measurement input. 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. Load c L2 UMG 96RM-E Fig.
UMG 96RM-E Current direction The current direction can be individually corrected via the existing serial interface or on the device for each phase. If incorrectly connected, a subsequent re-connection of the current transformer is not required. When residual current measurements (RCM) are being carried out, there is no direction sensitive difference in the residual currents on the network or load side (not directionally sensitive).

UMG 96RM-E Digital outputs - Status displays The status of the switching outputs of group 1 is indicated by circular symbols in the display of the UMG 96RM-E. Group 1 Status digital output 1 Status digital output 2 Digital output stati The current flow can be <1mA. Digital output 1: Addr. 608 = 0 Digital output 2: Addr. 609 = 0 The current flow can up to 50mA. Digital output 1: Addr. 608 = 1 Digital output 2: Addr.
UMG 96RM-E 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.
UMG 96RM-E Pulse length The pulse length applies to both pulse outputs and is set by the software GridVis. The typical pulse length of S0 pulse is 30ms. Pulse interval The pulse interval is at least as large as the selected pulse length. The pulse interval depends on the measured power, for example, and can take hours or days. Pulse length 10ms ..
UMG 96RM-E Pulse value The pulse value is used to indicate 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 you check the pulse value with a positive sign, the pulses will only be emitted when the measured value has a positive sign. If you check the pulse value with a negative sign, the pulses will only be produced when the measured value has a negative sign. Pulse value = C C max.
UMG 96RM-E Determine the pulse value External 230V AC operating voltage Set the pulse length Set the pulse length in accordance with the requirements of the connected pulse receiver. At a pulse length of 30 ms, for example, the UMG96RM generates a maximum number of 60,000 pulses (see Table "maximum number of pulses" per hour.
UMG 96RM-E Comparators and monitoring threshold values Five comparator groups (1-5) and 10 comparators per group (A – J) 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. Fig.
UMG 96RM-E Service and maintenance Service The device is subjected to several different safety tests before leaving the factory and is labelled with a seal. If a device is opened then the safety checks must be repeated. Warranty claims will only be accepted if the device is unopened. Should questions arise, which are not described in this manual, please contact the manufacturer directly.
UMG 96RM-E 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.
UMG 96RM-E Battery monitoring function The device indicates the condition of the battery via the "EEE" symbol followed by "bAt" and the status number. Depending on the status number a confirmation of the information by the operator may be required. It is recommended that the battery be replaced.
UMG 96RM-E Replacing the battery If the battery capacity is shown as < 75 %, we recommend that the battery be replaced. Procedure 1. Disconnect system and device from power supply before beginning work. 2. Discharge any electrostatic charge in your body, e. g. by touching an earthed cabinet or metal part (radiator) connected to the earth of the building. 3. Remove the battery from the battery compartment, —e.g. using long-nose pliers—.
UMG 96RM-E Error/warning messages Warnings The UMG 96RM-E can display four different error messages: Warnings are minor errors that can be acknowledged by buttons 1 or 2. The measured values continue to be retrieved and displayed. This error is displayed after each voltage return. • • • • warnings, clock/battery errors, fatal errors and overranges. In the case of warnings and fatal errors, the error message is followed by the "EEE" symbol and an error number. Fig.
UMG 96RM-E 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". Fig. Clock / battery error number 330 (clock does not run and has to be set. Major errors When a major error occurs, the device must be sent to the manufacturer's service center for inspection and adjustment.
UMG 96RM-E Overranges Overranges are displayed as long as they exist and cannot be acknowledged. An overrange exists if at least one of the four voltage or current measurement inputs lies outside their specified measuring range. The "upwards" arrow indicates the phase (L1-L3) 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.
UMG 96RM-E Parameter overrange A detailed description of the error is coded in the parameter overrange (Addr.
