Over Load Protection

load protection.

Over Load in based on internal counter that in increased when input value is above 105 % level and

decreased when below 105 % level, increase and decrease is happening every 100 ms.

Tripping is made when over load counter value is over 10 000.

With parameters it can be defined what is increase (Over load maximum step) at maximum defined

input level (Over Load Maximum Input). These points defines slope for the function. e.g. if input value

is middle of 105 % and Over Load Maximum Input values counter is increase half of the Over Load

Maximum step.
