Universal Motor Controller
UMC100-FBP
Technical Description
Control Function Overload Relay
The UMC100 parameterised with the control function 'Overload relay' can be used to replace a standard
overload relay.
The outputs DO ... DO3 and the inputs DI0 ... DI5 are directly connected to the ieldbus and not used
from the control function.
If a fault output is activated the fault output (DO or 4 V DC Out DO3) cannot be controlled from the
ieldbus anymore but is controlled by the UMC itself.
After powering up, contact DO0 immediately closes and contact DO1 opens.

Fault Behaviour:
•
Contact DO0 opens
•
Contact DO1 closes
•
The fault output DO/DO3 is activated if conigured
•
The monitoring signal FAULT is sent to the ieldbus
•
The red LED on the UMC is switched on
•
The FAULT signal on the control panel lashes.
