A.10.10. Clip Detector Option<br />

The clip detector option reduces flow rate errors on light loaded belts caused by<br />

conveyor belt weight variances. Turning on Auto Zero Tracking in the Cal Data<br />

Scroll enables the clip detector. The clip detector is normally a proximity switch<br />

that senses a metal target attached to the belt. In manual mode, the clip detector<br />

freezes the flow rate when the clip is detected and maintains it frozen for the<br />

programmed length. Totalization is not affected. In automatic, the Integrator<br />

automatically detects tare variations and compensates for them.<br />

If the clip detector is assigned to one digital I/O input, the following screens<br />

appear.<br />

In the MANUAL mode, the user must enter the length of belt, which is affected,<br />

by the belt splice. The system freezes the belt loading when the clip is detected<br />

and maintains it frozen until the specified belt length has passed.<br />
