The LCD operator panels UMC22-PAN and UMC100-PAN allow to monitor, configure and control the UMCs. They can be mounted separately from the UMCs e.g. on the switchboard door. Three colored LEDs show the device status.
The ground fault monitors CEM11 monitor the sum of the currents in the motor feeder cable. The alarm level can be adjusted stepwise. Only four devices (20mm – 120mm) cover the current range from 80mA – 13.6A.
For applications with many IO signals the UMC100 can be expanded with additional 8 digital inputs, 4 relay outputs and one analog output using either the DX111 or DX122. The two modules are only different regarding the specification of their digital inputs (24VDC resp. 110VAC – 230VAC).
The VI150 and VI155 modules extend the UMC100 with functions such as detection of mains voltage, cosphi, power and energy. Additional protection functions are thereby provided, e.g. underload detection for a pump based on the active power.
At motor currents > 63A an additional external current transformer is needed.
With only four types the nominal current range can be extended up to 850A.
Universal Motor Controllers
Using the UMC offers various benefits during the plant engineering, for the panel builder and finally for the plant operator.
-
· Reduced engineering effort because of its flexibility and thereof the need for less typicals
· Reduced number of spare parts (one device over the whole current range and trip classes)
· Easy to install because it is built for MCC usage
· Fast location of faults due to clear text diagnosis messages at the LCD panel
· Reliable integration into different control systems and fieldbusses
