7.9. System of elektroblokirovkizamk of doors

Possible malfunctions of electroblocking of locks and ways of their elimination



The system is intended for simultaneous blocking of locks of all doors when locking by a key of the lock of the left forward door, and also when pressing the button of blocking of the lock of the left forward door.

Fig. 301. Scheme of system of electroblocking of locks of doors: 1 – motor-reducer of blocking of the lock of a forward right door 871.3730; 2 – motor-reducer of blocking of the lock of a forward left door 87.3730;
3 – control unit of system of electroblocking of locks of doors 7403.3761; 4 – motor-reducer of blocking of the lock of a back left door 871.3730; 5 – motor-reducer of blocking of the lock of a back right door 871.3730; 6 – motor-reducer of blocking of the lock of a door of a back 871.3730


The scheme of system of electroblocking of locks of doors is given in fig. 301.

Fig. 302. Conditional numbering of plugs in blocks of motor-reducers of electroblocking


Fig. 303. Conditional numbering of plugs in a block of the control unit of electroblocking of doors


In fig. 302 and 303 conditional numbering of plugs in blocks of motor-reducers and the control unit is shown.
Drafts of blocking of locks are given by the motor-reducers established in each door. The motor-reducer of the left forward door has the built-in switch which contacts are switched when moving the button of blocking of the lock or at turn by a door lock key. Through the closed contacts of the switch the signal on the control unit 3 is given (see fig. 301), and it includes all motor-reducers.

Note
The control unit and motor-reducers are not subject to repair. At failure – replace.
