UMG 96RM Device address (addr. 000) Mean value 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. Mean values are formed over an adjustable for the current, voltage and power measured The mean values are identified with a bar the measured value.
UMG 96RM Averaging method Minimum and maximum values After the set averaging time, the exponential averaging method used achieves at least 95% of the measured value. All measured values are measured and calculated every 9 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.
UMG 96RM Mains frequency (addr. 034) A voltage L-N of greater than 10V effective voltage must be present on at least one of the voltage measurement inputs in order that the mains frequency can be detected automatically.

UMG 96RM Energy meter Reading the active energy The UMG 96RM has energy meters for active energy, reactive energy and apparent energy.
UMG 96RM Harmonics Total Harmonic Distortion (THD) Harmonics are the integer multiple of a mains frequency. The voltage mains frequency for the UMG 96RM must be in the range between 45 and 65 Hz. The calculated voltage and current harmonics refer to this mains frequency. Harmonics up to 40x the mains frequency are recorded. THD is the ratio of the root mean square value of harmonics to the root mean square value of the mains frequency.

Serial number display Serial number information on the nameplate: XX00-0000 Software release (addr. 750) The software for UMG 96RM is continuously improved and expanded.

UMG 96RM Commissioning Applying the measured current Applying the supply voltage The UMG 96RM 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 96RM with the applied current. The current displayed by the UMG 96RM must match the input current, taking the current transformer ratio into consideration.
UMG 96RM Rotation field direction Checking the measurement Check the direction of the voltage rotation field on the measured value display of the UMG 96RM. Usually there is a "clockwise" spinning rotation field. If all voltage and current measurement inputs are correctly connected, the individual and sum power ratings are accurately calculated and displayed.
UMG 96RM 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 must also be correct. For confirmation, the sum power ratings measured by the UMG 96RM should be compared with the energy of the active and reactive power meters at the power feed.
UMG 96RM RS485 interface The data from the parameter and measured value list can be accessed via the MODBUS RTU protocol with CRC check to the RS485 interface.

UMG 96RM Pulse output Measured value selection (addr. 100, 101) Among other things, the digital outputs can also be used for the output of pulses to meter the energy consumption. After reaching a certain adjustable amount of energy, a pulse of defined length is applied to the output. Various adjustments must be made in order to use a digital output as a pulse output. Enter the power value here that is to be issued as an energy pulse. See Table 2.
UMG 96RM Pulse length (addr. 106) 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 Due to the minimum pulse length and minimum pulse pause, the values in the table are for the maximum number of pulses per hour. Pulse length Pulse pause Maximum pulses/hour The typical pulse length for S0 pulses is 30 ms.
UMG 96RM 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.
UMG 96RM Determining the pulse value External 230 V AC operating voltage 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 96RM can issue a maximum number of 60,000 pulses (see Table "Maximum Pulse Number") per hour.

UMG 96RM Brief instructions Current transformer setting, primary current Changing the current transformer setting Display Programming mode Switch to programming mode: • Simultaneously press buttons 1 and 2 for approximately 1 second in order to switch to programming mode. The symbols for the programming mode (PRG) and for the current transformer (CT) appear. • Confirm the selection with button 1. • The first digit of the input area for the primary current starts flashing.
