1. CIRCUIT DIAGRAM AND EXPLANATION
• Controlling load of button input in MICOM terminal, it is selected to 'L' or 'H'. It is selected to 'H' in
running load case and in 'L' case, load driving is finished, In clockwise rotation of washing motor, as
MICOM No. 31 is changed 0V to 5.4V, TR Q1(KTN2222S) is turn on. And then, the TRIAC1(SM
12JZ47) is turn on, the source of electric power is supplyed to washing motor for clockwise rotation.The
TRIAC as switching element, force to 'ON' or 'OFF' by use of the Q1 (KTN2222S) in the rest loads,
when the MICOM terminal voltage change 0V to 5.4v, each TRIAC DRIVE TR is active, and then TRIAC
switches the source of electric power to loads.
• The purpose of using the MICOM terminal No. 6 Q2(KTA 1664) is that the Q2 prevents the instant
supply of electric power supply to loads, in case MICOM's action is wrong by means of pushing initial
power switch.
