Power supply and start, machine with coin meter

Some control circuits do not receive voltage until the door and lock switch

S3 (2) are closed (point B ). Others receive voltage even when the door is

open (point A ). These feed points recur in other function diagrams.

The same conditions apply for feed points C and D . Point C does not

receive voltage until a switch S4 (8) in the safety lock delay unit is closed

(i.e. the door is locked). Point D receives voltage even when the door is

open.

Start

When a program is completed, the machine stops at program stage 53 and

the door can be opened.

The door must be closed for the machine to start. It is only when the door is

closed that impulsegenerator B21 (5) in the coin meter receives voltage.

The coin lock B26 (5) also receives voltage since row 10a (3) is closed at

stage 53. This means that the lock in front of the coin slot can be moved

and a coin can be inserted.

When the correct amount of coins have been inserted into the coin meter

the impulse generator's contact with COM-NO position and the coil for timer

(5) receives voltage (row 34 (5) is closed at stage 53).

At stage 54 row 34 is released but the timer advances to stage 1 since row

33 (7) is closed at stage 54. This design feeds the timer forward to stage 1

regardless of how long the impulse generator's contact remains in COM-NO

position.
