Office lighting
Application example: office lighting
The aim is to light offices with automatic switch-off set according to defined time slots.
The proposed solution is as follows:
z The office lighting is controlled by Reflex iC60 circuit breakers without Ti24 interface (A9C5••••) set to
mode 2. In this mode, when Y1 is at high state, the circuit breaker is open and the controls on input
Y2 are inhibited. When input Y1 is at low state, the circuit breaker is controlled by input Y2.
z Pushbuttons are used to control the office lighting locally via input Y2.
z A weekly programmable timer switch is used to override switching off of the lighting outside office
opening times by periodically sending pulses on input Y1.
