The 8 Series can simulate current and voltage inputs with the selections available under
the Simulation feature. Other test operations are also possible such as LED lamp test of
each color, contact input states and testing of output relays.

The Simulation feature is provided for testing the functionality of the 8 Series in response
to programmed conditions, without the need of external AC voltage and current inputs.
First time users will find this to be a valuable training tool. System parameters such as
currents, voltages and phase angles are entered as setpoints. When placed in simulation
mode, the relay suspends reading actual AC inputs, generates samples to represent the
programmed phasors, and loads these samples into the memory to be processed by the
