Mode of operation

Logical combination of binary input signals or of output signals from the protection functions,
for example, for:
• specific signals required by the application
• supplementary protection functions

OR gate with 4 inputs
AND gate with 4 inputs
R/S flip-flop with 2 inputs for setting and 2 inputs for resetting:
• The output is 0, if at least one of the reset inputs is 1.
• The output is 1, if at least one of the set inputs is 1 AND none of the reset
inputs is 1.
• The output status is sustained when all the inputs are at 0.
Every logic has an additional blocking input, which when activated switches the
output to 0.
