1. LOAD DRIVING
CIRCUIT
* InEven if opening the door of freezing room or cold storage room during operation of fan motor at the freezing room, this
circuit does net stop and operates at the standard RPM. In addition, if doors of freezing room or cold storage room, the
fan motor normally operates at the RPM previously
operated.
(A), (B), (C) and (D) of door switch for the freezing room or cold storage room are connected to the door open sensing
circuit in parallel toward both ends of switch to determine door open at MICOM.
Since a door switch of the home bar is connected to door switch (C), (D) of the cold storage room, it senses door opening
if even one of both is opened.
The fan motor is immediately stop if opening doors of the freezing room or cold storage room at the TEST mode and it
immediately operates if closing them.
