DescriptionThe door lock motors are operated simultaneously upon a command:from the key;from the front door switches (knobs);from the remote control (if present)Locking operation: when the key is used on one of the two front doors or the remote control is operated when the doors are firmly shut and the front locks locked, all four side doors are locked simultaneouslyUnlocking operation: when the key is used on one of the two front doors, with front locks locked, or the remote control is operated, all four doors are unlocked.This control logic is controlled by the specific control unit in the driver's glove compartmentThe control unit also carries out a series of safety checks:the control unit checks the actual status of the locks: the "lock" or "unlock" command is only executed with the doors properly closed: if the door being operated is not shut properly, the command is inhibited; if the door opposite that being operated is not shut properly, and an immediate "repulsion" is carried out (i.e. the opposite action is carried out to "realign" the locks).if there is a rapid succession of alternating lock/unlock commands, the control unit only carries out the first three commands without activating the inhibition. Similarly if 8/9 opening and closing actions are carried out in 20 seconds (the last is always a closure), the circuit is then inhibited for about 30 s.the circuit can be further inhibited if the battery voltage falls below 9 V within 20 ms. from the start of activation of the lock/unlock actions. During the inhibition time (30 s), the commands are ignored.The locking or unlocking command is also carried out via the remote control receiver, both on versions with an alarm and on versions with a door remote control only.On versions with an alarm, the locking or unlocking command is also carried out via the remote control receiver.The central locking circuit is protected by a special fuse next to the junction unit.
Functional description The M80 central locking control unit controls the operation of the circuit. The M80 control unit (pin +) is supplied directly by the battery via the line protected by the special fuse B19 ; pin (-) provides the reference earth. Control unit M80 receives input signals coming from locks N50 and N51:for locking, if the earth signal goes from pin 2 to pin 3 of M80 ;for unlocking, if the earth signal goes from pin 3 to pin 2 of M80 . The same signals arrive from pins 5 and 6 of the receiver for the remote control M35 . On versions with an alarm, the same signals arrive from pins 5 and 6 of the receiver for the remote control M35 . In accordance with the logic illustrated previously, control unit M80 simultaneously controls the two front locks N50 and N51 and the rear locks N55 and N56 from pins 1M and 2M:locking signal; 12V from pin 2M and earth to pin 1Munlocking signal: 12V from pin 1M and earth to pin 1M
