Industrial Terminals Typical Connection Diagram – Terminal Cong 1
General
This section shows the typical congurations applicable to a wide range of industrial applications.
The motor speed may be controlled from the local console on the MSC-3 or a remote signal source.
Switching between local and remote operation is controlled by a contact closure. This terminal
conguration is the factory default. Several alternative arrangements for starting and stopping are
shown.
