Raise and Lower Inputs

When a raise or lower input is received, voltage is applied to the motor,

causing it to rotate and move the slider of the potentiometer.

If a raise input is received, the polarity of the applied motor voltage causes

the motor and potentiometer to rotate in the clockwise direction.

This clockwise rotation continues until 24 Vdc is removed from the motor

due to removal of the raise input or activation of the clockwise limit switch.

If a lower input is received, the polarity of the applied motor voltage causes

the motor and potentiometer to rotate in the counterclockwise direction.

This counterclockwise rotation continues until 24 Vdc is removed from the

motor due to removal of the lower input or activation of the counterclockwise

limit switch.

Dynamic Braking

Dynamic braking is obtained by placing a short-circuit across terminals 5 and

7. An available accessory switch provides the necessary contact arrangement

for the raise/lower function and dynamic braking.
