? Logic equations

Are used to made additions to standard processing operations.

Logic equation create simple logic functions by combining data received from

– protection functions – or logic inputs.

Logic equation use:– logic operators (and, or, xor, not)– and time delays

Logic equation may not be used to:– modify standard circuit breaker control, logic discrimination or recloser

functions– create as complete control logic schemes as with Logipam

Series 40 & 80

? Logipam

Customize SEPAM Series 80

Based on the ladder diagram principle

For specific complex functions and automation:– specific source transfer– motor starting sequence– load shedding– management of cubicle peripheral equipment

– etc ...
