Engaging/Disengaging the ERMS Function

Presentation

The ERMS function is used to reduce protection settings so that the circuit breaker trips as soon as possible when an electrical fault occurs. Minimizing the time between the electrical fault and circuit breaker trip helps to reduce the risk of injury when qualified electrical personnel are near energized equipment.

When the ERMS function is engaged, the ERMS protection settings replace the standard protection settings.

Availability

The ERMS function is available on MicroLogic Active 2.0, 5.0 and 6.0 control units for IEC standard.

Operating Principle

The ERMS function can be engaged or disengaged by using the ERMS button.

While the ERMS function is engaged: The ERMS LED (A) is lit in blue. The LSIG home screen (B) is blue. The Quick View screens are blue. All other screens are not blue.
