CAUTION:
1. For LED of ERROR and PE, there is a resister of 330Ωon the circuit side to make current
value 10 mA.
Please use LED which its voltage is approx. 2V. LED over 10 mA may break a control board.
2. Control circuit requires power supply only for one pin of each VCC and GND.
However, Operation voltage is to be supplied to all of pin for safety use.
3. Serial interface equips a driver and receiver of RS-232C, make sure to use it at RS-232C
level.
4. RESET terminal is pulled up by 3.3KΩ. Make sure to make this terminal NC, when this
terminal is not used.
5. LF-SW input circuit is as below.
