Equipment Description
Overview This chapter describes the features of the Bulletin 1406 to Bulletin 825 Plus
Conversion Kit.
Operational Requirements Monitoring application parameters and process data of an installation is
very important. Even a slight change in the starting and operating behavior
of the motor can indicate an impending fault. The Bulletin 825 Plus helps
eliminate the potential trouble before major repairs are necessary and loss
of production occurs.
The Bulletin 825 Plus fulfills these requirements by providing the
following protective functions:
• High overload, stalling
• Underloading
• Wrong direction of rotation
However, the Bulletin 825 Plus functionality does not directly correspond to
the Bulletin 1406. Below is a summary of some of the features offered by
the Bulletin 825 Plus. In most cases the 825 Plus provides improved and
additional features/protection.
