Limit Switch Circuits
In operation, power is applied to the SL10U control and the
appropriate voltage to L1 and L2. When PB1 is actuated, the motor
will run forward until the limit switch is actuated and the motor
dynamically brakes to a stop. When PB3 is actuated, the motor will
run in reverse until the other limit switch is actuated and the motor
dynamically brakes to a stop. When PB2 is actuated, the motor will
dynamically brake to a stop. When the motor is running, a change
in direction is not possible without actuating PB2 (BRAKE) first. If
dynamic braking is not desired eliminate the jumper wire.
Refer to Figure 20 (page 44) for an illustration of relay reversing
with dynamic braking and limit switches.
