Power supply and start, machines without coin meter
Some control circuits do not receive voltage until the door and lock switch S3 (3) 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 (9) in the safety lock delay unit is closed (i.e. door is locked). Point D receives voltage even when the door is open.
Start
When a program is completed, the machine stops at progam 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 row 11a (5) receives voltage. When S6 is pressed to start a new program, the coil for rapid advance (8) receives voltage since row 11a (5) is closed at stage 51.
At stage 52 the timer stops until S6 is released. The timer then advances to stage 1 (row 15a (6) is closed at stage 52) and the wash program begins. This design prevents accidental excess rapid advance of the timer when starting
Program advance
By holding down S6 the timer can be advanced past different wash cycles (row 4a (4) is closed in stages
