Position Auxiliary Drive LHS NC_MO02 / Position Auxiliary Drive RHS NC_MO03<br />

The auxiliary drives are positioned by DC motors:<br />

− NC_MO02 Auxiliary drive LHS<br />

− NC_MO03 Auxiliary drive RHS<br />

A control disk is used for the positioning of the<br />

auxiliary drives which activates and deactivates a<br />

light sensor (1) as a function of the angle:<br />

− NC_LS07 Auxiliary drive LHS<br />

− NC_LS08 Auxiliary drive RHS<br />

Upon the initialisation, the initial position must be<br />

found by means of the following signals:<br />

− NC_LS07 / NC_MO02_DONE LHS<br />

− NC_LS08 / NC_MO03_DONE RHS dlabr027<br />

The frosted glass turns in the indicated direction. In<br />

the figure, the auxiliary drive is in the bottom<br />

position.<br />

It must be observed that the motor continues turning<br />

approx. 30° when lowered. When lifted, the motor<br />

must press against a spring and therefore does not<br />

afterrun so much.<br />

The DC motor is switched off automatically by the<br />

Hardware at the dark/bright transition (DONE signal<br />

going to High).<br />

Upon the initialisation, the current position can be<br />

defined by time measurements on the light<br />

sensor (1).<br />
