The product which manages the quantity of wraps or amount of turntable revolutions is timer TD-1. For purposes of this description, it is presumed that 3 wraps are wanted and this the machine pace is 10 rpm. Using a rotational speed of 6 secs per emerging trend, TD-1 has to be established somewhere between 10 and 16 mere seconds. Only two wraps will result and if TD-1 is set over 16 seconds, 4 wraps will result, if TD-1 is set less than 10 seconds.
As a way to commence functioning of your machine, the owner presses the start key found on line 7 which energizes communicate coil CRM on line 10. Invigorating relay coil CRM shuts normally wide open associates on facial lines 11, 10, 8 and 4 and starts normally shut down relationships on line 8. All of the contacts inside the sketches are mentioned as parallel lines with the note designations related to the particular communicate coil which causes possibly the opening up or the shutting down of those relationships. When a lines are proven from the parallel collections, this indicates a typically sealed speak to although without having the series the illustration is of any usually open speak to. Associates on line 10 preserve capacity to communicate coil CRM when the commence key is introduced. The associates on line 4 then provide Air conditioning power to the turntable engine control online 4 along with the contacts on the internet 8 available to be able to disconnect braking resistor R2 from the circuit. As well, other sets of contacts online 8 near in order to source DC ability to the motor unit. At the same time AC strength comes to clock TD-1 on line 13 which starts to count seconds. Furthermore, Air conditioning strength is supplied to timer TD-2 on line 16 which also begins to count up mere seconds.
At this moment over time, turntable 4 is turning and in the beginning the anxiety on the stretchable material is set at 1 / 2 of complete anxiety. The Air conditioning energy is applied on the rectifier on outlines 24/25 through resistor R1 on line 26 and therefore DC energy is applied to the braking system inside the half pressure system.
When clock TD-2 times out, which can be usually at the time set up between 2 and 4 seconds which is the same as roughly 1/2 of the turntable innovation, contacts TD-2 on the web 24 shut to be able to sidestep resistor R1 as well as to apply a total Air conditioning voltage on the rectifier and thus whole DC voltage towards the braking system of the one half anxiety system. The maximum braking voltage setting is determined by the setting of rheostats on lines 28 and 30, however.
