also connected to conductor 32 via a self energizing contact 44 and a further contact 35 operated by time relay 26 the auxiliary relay 27 is connected to conductor 34 through a contact 36 operated by the time relay 25 the auxiliary relay 27 controls via a contact 37 the application of supply current from a terminal 38 via a terminal 39 to a thyristor control circuit for the motor 21 moreover relay 27 through a contact 40 controls the switching off of a reversing motor 42 which is supplied with voltage via a terminal 41 the reversing motor 42 is provided for controlling the reversing movement of the motor 21 and hence the movement of drum 12 during the dyeing process moreover the reversing motor 42 controls the position of contact 33 which is a necessity for the reason that the distributing speed may be switched on only when drum 12 is rotating i e when reversing motor 42 is functioning referring to the wiring diagram of fig2 the following function of the textile dyeing machine can be determined the desired cycle time for example 120 seconds is set on time relay 26 and the desired process time at distributing for example 10 seconds is.
