3.2. QF2 breaker
Breaker QF2 protects the one phase 220V AC which powers PLC. If the
one phase required power exceeds 4A, the breaker activates and
terminates 2 phases.
After the problem is fixed, reset the breaker by flipping lever B up.
3.3. Transformers
The transformer supplies 20V AC and 110V AC to the bar feeder.
The incoming power must be connected to the Primary terminal block.
Use the contacts corresponding to the supplied power (190V AC to 480V AC, see drawing below).
There are 2 sets of independent power supply unit on the secondary terminal.

Unit A supplies 110V AC.

Unit B supplies couple alternatives output power but the wiring must ALWAYS connected to 0V/20V !
Never connect the unit B to 0V/24V.
3.4. 24V DC power supply
The bridge rectifier converts the AC power from transformer and offer 24V DC to proximity switches,
interface signals, remote control, solenoid valves and buzzer.
