Recorded data

When the relay performs a tripping, the cur-
rent values at the moment of tripping, the du-
ration of the starting for different units and other
parameters are stored in a two place memory
stack. A new operation moves the old values up
to the second place and adds a new value to the
first place of the stack consisting of registers
1...9. Two value pairs are memorized - if a third

A master reset of the relay erases all the con-
tents of both of the register blocks.
The left-most red digit displays the register ad-
