Main features and functions

 Main features
This section describes the main features fro Model KE1.
• Models providing the following functions are lined up and are selectable according to intended
end-usage.
 Power measurement
 Overvoltage/undervoltage detection
 Voltage sag (instantaneous voltage drop) detection
 Addition of ZCT (eight circuits)
 Opposite phase detection
* Adding CT and ZCT requires connecting them to the measurement master.
* Chapter 3 describes the functions in details including the ones not described above.
[Connection of multiple units]
・ For example, electric power and current of up to 35 circuits can be measured by connecting the
CT extension unit (KE1-CTD8E) to the measurement master unit.
* For information on the combination of units that can be connected, refer to page A-20.
[Connection with Model KM1]
Connection with Model KM1 series is available. Connecting "Model KM1-EMU8A-FLK" to Model
KE1 measurement master unit allows enhancing the temperature measurement functionality.
* For information on the combination of units that can be connected, refer to page A-20.
*1 CompoWay/F is a unified communication procedure within Omron's generic serial communication.
It has commands conforming to the time-proven FINS in the unified frame format and Omron's
programmable controller, making easy the communication between the personal computer and the
components.
*2 Communication control system conforming to RTU Mode of Modbus Protocol. Modbus is a
registered trademark of Schneider Electric.
* For information on Model KM1, refer to "Model KM1 User's Manual" (KANC-701).
