Features

Peak load shaving for the maximum monitoring (Emax)

• There are 64 steps of load shut down possible (depending on the hardware setup)
• The configuration and monitoring is provided on the homepage of the device
• The shutdown of each load can be activated by digital outputs of the FBM module (optional) via Profibus or Modbus
• For the use of the APP you have to acquire the Emax license.

Integrated "Watchdog" function for continuous monitoring of the power quality per EN 50160

The power quality on the supply side should comply with EN 50160. This standard describes various power quality parameters for the distribution of electrical power on public power grids. EN 50160 pertains to mains voltage, i.e. the voltage measured at the mains connection point. With power quality monitoring per EN 50160, all the algorithms (including for 95% and 100% values) are integrated in the measurement device itself.

The auxiliary voltage of the device should be buffered to ensure that power failures can be reliably detected as events.

• Integrated watchdog function
• No need to transmit large volumes of measured data from the measurement device to a host system
• Save on communications costs for applications with remote consumers
• Simple analysis possible thanks to integrated colour display based on a "traffic light" system
• Possible to perform power quality analyses even with no particular knowledge on the topic
• No alarm functionality

Processing and recording of up to 8 temperature / moisture sensors possible

• Can process and record the measured values from up to 8 temperature/moisture sensors (item no. 1506074)
• In doing so the display of the measured values is implemented via a homepage after installing the APP, or via global variables in the GridVis®
• Measured values can be saved in a second Jasic® program via the graphical programming
• Delivers two analogue 4 - 20 mA output signals, which will be processed by the function module FBM DI8AI8 (item no. 1506079)

Integrated "Watchdog" function for continuous monitoring of the power quality per IEC 61000-2-4

The standard IEC 61000-2-4 defines numerical limits for industrial and private power distribution systems at rated voltages up to 35 kV. For the consumer, the standard IEC 61000-2-4 should be applied with reference to power quality. Therefore the power quality in all technical systems must be continuously monitored in accordance with IEC 61000-2-4, in order to ensure fault-free operation of the installed system.

The auxiliary voltage of the device should be buffered to ensure that power failures can be reliably detected as events.

• Integrated watchdog function in accordance with standard IEC 61000-2-4
• No need to transmit large volumes of measured data from the measurement device to a host system
• Save on communications costs for applications with remote consumers
• Simple analysis possible thanks to integrated colour display based on a "traffi c light" system
• Possible to perform power quality analyses even with no particular knowledge on the topic
• No alarm functionality

Reading out 30 measured values and max. 31 slave devices via RS485

• Reads out 30 measured values (fi xed default value) from up to 31 slave devices (confi gurable) via RS485
• Filing of the measured values in the master in global variables or on BACnet data points
• Display of the measured values is implemented via the JPC35 touch panel or via the device homepage (browser with FLASH plug-in necessary)
• Expansion for live value display
• Integrated BACnet gateway function (option, item no. 52.16.083)
• The BACnet-ID can be changed via the homepage
• Program installs a control program
• Depending on master device (UMG 604, UMG 605, UMG 508, UMG 511), call-up of a corresponding sub-program (slave devices: UMG 103, UMG 104, UMG 604, UMG 605 and UMG 96RM)
• Possible communications fault (RS485-Bus) directly visible via a status display
• The number of devices and device descriptions can be confi gured via the master devices homepage
• The master device is automatically recognised and entered in the "Device type" fi eld
• The BACnet confi guration is likewise implemented via the master device homepage
• Each device can be assigned its own BACnet-ID
• EDE fi le for the import of the BACnet data points in a BACnet-GLT is included in the scope of deliverables for the APP

The "Limit value alarm via SNMP" application monitors the settings made on the web page and in GridVis and sends an SNMP trap when it is exceeded

• The trap number is freely selectable
• Each trap number can be assigned to one or more monitor systems
• This trap is then sent depending on the set logic (AND/OR), if only one limit value is exceeded (OR),
  or only when all configured limits of this trap have been exceeded (AND)
• The traps can be sent up to two SNMP hosts
• The following measured values ​​and events can be monitored:
  - Configuration via GridVis: voltage failure, undervoltage, overvoltage, overcurrent, transients, RCM (only UMG 509 & UMG 512)
  - Configuration via the web page: Frequency, Power, Heartbeat (watchdog, no configuration option).

• APP with extensive options for setting limit values and analysing fault currents in detail
• Up to 20 RCM channels can be managed and evaluated via a gateway
• The evaluation covers all types of residual current with an associated frequency analysis
• For example, 50 Hz, pure DC or high-frequency residual currents in the 20 kHz range can be displayed individually
• In addition, the application enables the proven dynamic limit value formation with Janitza energy measuring devices
• Energy measuring devices can be assigned to each of the 20 RCM channels and limit values can be calculated as a function of power
