Intelligent motor protection relay is simple to use

April 2000 Motion Control & Drives

The MP-3000 motor protection relay replaces the existing IQ-1000 II electronic relay having all present features in the same cut-out design while offering the additional features:

* Provides motor protection through Intel-I-Trip (overload protection – a field proven algorithm that develops custom trip curves from motor manufacturer data.

* Meets the standards for UL-1053 (the standard for groundfault sensing and relaying equipment) - which eliminates the need for a separate relay, thereby resulting in panel space and cost savings.

* Date and time stamped information, including an event log and details of trips, alarms and starts is available at the device or via the communications facility, making motor diagnostics easier.

* Both a 5 and a 1 A version are available.

* A test page in the program mode provides display indication of the discrete input states and testing of the output relays, target LEDs and analog circuit.

* A user-friendly operator interface and display provides quick access to the settings, monitored values, motor history and operational logs. Large LED alphanumeric character display provides easy viewing from any angle in any light. Simple keypad operation provides quick and easy navigation through all settings and stored data.

* The MP-3000 motor protection relay provides protection against motor overloads, short-circuits and abnormal oper-ating conditions.

Some enhanced features include:

* Built-in help program.

*Built-in test mode.

*LED indication.

*Microprocessor-based.

*Self diagnostics.

*Programmable inputs.

*Programmable outputs.

*Realtime clock.

For over 70 years CHI Control, an ISO 9001 listed company, has represented Cutler-Hammer USA as sole distributor of low and medium voltage motor control equipment for the light and heavy duty industrial markets throughout sub-Saharan Africa.
