Mode 2
Mode 2 is used for local opening/closing and centralized opening of the circuit breaker:
z Y1: local opening control on rising edge, latched at high state (state = 1) to inhibit Y2
z Y2: local one-shot closing and opening control
z Y3: centralized closing control on rising edge and opening control on falling edge
NOTE: Y3 is only available in Reflex iC60 versions with Ti24 interface.
The following diagram shows operation of the version without Ti24 interface.
Operation is as follows:
z When input Y1 is at 1, input Y2 is inhibited
z When input Y1 is at 0, a pulse on input Y2 makes the Reflex iC60 circuit breaker switch alternately
from Ready position (contacts open) to closed position
The following diagram shows mode 2 operation of versions with Ti24 interface.
Operation is as follows:
z
A rising edge on input Y1 makes the Reflex iC60 circuit breaker switch to
Ready
position (contacts open)
z The state of input Y3 is taken into account on falling edge of Y1. If input Y3 is at 1 when there is a
falling edge on Y1 the Reflex iC60 circuit breaker switches to closed position
z Input Y2 is inhibited when input Y1 is at 1
z If input Y1 is at 0, a pulse on input Y2 (rising edge) makes the Reflex iC60 circuit breaker switch
alternately from Ready position (contacts open) to closed position
z Input Y3 (Ti24) is operational if Y1 is at 1 or at 0:
z When input Y3 (Ti24) changes to 1, the Reflex iC60 circuit breaker switches to closed position
z When input Y3 (Ti24) changes to 0, the circuit breaker switches to Ready position (contacts open)
