8-7. LOAD OPERATION circuit part
When ÒHighÓ signal is supplied to INPUT of IC03 (ULN2003A) at MICOM PIN NO #22 (P15), IC comes to be
turned on. At this time, if V12 (DC 12V) supplied to the lower COIL of COMP RELAY runs into GROUND
through OUTPUT of IC03, magnetic field will occur at CORE and then make contact point ON. This approves
220 V to COMP LOAD to make COMP ON and, if MICOM PIN NO #22 becomes ÒLowÓ state, IC comes to be
TURN OFF state to make current not running to COMP RELAY COIL, to make RELAY contact point OFF state,
and then, finally to stop COMP.
