3. Multiple cam<strong><strong>controller</strong>circuit</strong>.gif

It consists of three cam controllers SAi, SA2 and SA3, which control
the operation of the cart, trolley and lifting mechanism respectively. Among them, SAi adopts KT12-25J/1 type cam controller. It has two sets of contacts for switching speed-regulating resistors
. It can switch two resistor boxes at the same time and is used to control the speed of two winding motors of the cart. This circuit is generally used in the control circuit
of 5/lOt bridge crane . The control circuit in the dotted box in the figure is similar to Figure 8-2 (b). In the figure, the contact closure conditions of   the trolley controller SAi, the trolley controller SA2 and the lifting controller SA3 are shown in
