Clip Detector Option The clip detector option reduces flow rate errors on light loaded belts caused by conveyor belt weight variances. Turning on Auto Zero Tracking in the Cal Data Scroll enables the clip detector. The clip detector is normally a proximity switch that senses a metal target attached to the belt. In manual mode, the clip detector freezes the flow rate when the clip is detected and maintains it frozen for the programmed length. Totalization is not affected. In automatic, the Integrator automatically detects tare variations and compensates for them. If the clip detector is assigned to one digital I/O input, the following screens appear. - I/O DEF SCROLL 10- Clip detector mode MANUAL CHOICE ENTER Password: Service Password: Service Password: Service Default: MANUAL Choices: MANUAL, AUTO In the MANUAL mode, the user must enter the length of belt, which is affected, by the belt splice. The system freezes the belt loading when the clip is detected and maintains it frozen until the specified belt length has passed.

If a selection other than OFF is made, the following screens allow the user to<br />

define the polarity and the parity check of the BCD output. The polarity<br />

selection reverses the signals from NO to NC and vice versa. If a parity<br />

criterion is selected, the most significant bit of the BCD output is used for parity<br />

check.<br />
