The following diagram shows mode 3 operation.
Operation is as follows:
z When input Y1 is at 0:
z input Y3 (centralized control via Ti24) is ineffective
z Input Y2 is operational (local control):
A pulse on input Y2 (rising edge) makes the Reflex iC60 circuit breaker switch alternately from
Ready position (contacts open) to closed position
z When input Y1 is at 1:
z Input Y3 (centralized control via Ti24) is operational:
• When input Y3 (Ti24) changes to 1, the Reflex iC60 circuit breaker switches to closed position
• When input Y3 (Ti24) changes to 0, the Reflex iC60 circuit breaker switches to Ready position
(contacts open)
z Input Y2 is operational (local control):
A pulse on input Y2 (rising edge) makes the Reflex iC60 circuit breaker switch alternately from
Ready position (contacts open) to closed position
z The state of input Y3 is taken into account on rising edge of Y1:
If input Y3 is at 1 when there is a rising edge on Y1 the Reflex iC60 circuit breaker switches to closed
position.
