Universal Motor Controller
UMC100-FBP
V 6
Technical Description
Control Function Pole-Changing Starter
Use this function in a feeder that requires a two-pole or dahlander motor to start-stop in one direction of
rotation.
•
Relay output DO0 is used by the control function to start the motor at speed one
•
Relay output DO1 is used by the control function to start the motor at speed two
•
Optionally DI0 can be used for contactor checkback supervision
•
Optionally DI4/D3 can be used to start the motor at speed one/two and DI5 to stop it
•
Optionally terminals named 4VDC Out (1) or DO (9) can be used as a fault output
The following diagram shows the UMC wired for two-pole operation. A signal lamp is connected to DO3
which serves as a fault output. The main contactor is connected to DO0 and DO1. Two auxiliary contacts
are used for contactor checkback monitoring. The motor can be started locally via DI4 (speed one) or DI3
(speed two) and stopped via DI5. The remaining digital inputs can be freely used.
