10 E501714 M 31 30B 1000 B200 DL DO DO DL 1 3 C774 7 0 I I Initial position: door unlocked - The door is locked using the button/key . The top switch is directly switched over via the rod linkage. As a result, a current will flow through the fuse, connection 30B, the motor ,the bottom switch and the top switch through connection 31 to earth. B ecause of the mechanical connection between the m otor and the locking button, the button m oves downwards. W hen the lower position is reached, th e ‘end st roke’ swit ch (t he lower swit ch in th e diagram) switches over .T he forces are transmitted from the motor to the locking button via a crank/connecting rod linkage. - The door is locked using switch C 774. When spring-loaded switch C774 makes a connection between connections 3 and 7, connection point DL of B200 is connected to earth. A s a result, a current will flow through the fuse, connection 30B, the motor and the bottom switch to earth. A brief moment is suf ficient to start the motor .Since there is a mechanical connection between the m otor and the locking button, the top switch will switch over immediately .A current will pass until the ‘end stroke’ switch interrupts the circuit. 200404 2-156 5 ELECTRICAL SYSTEM Electrical system CF65/75/85 series ≥0E621376 |
