A special case of the accumulate signal for the most downstream zone is referred to as Lane Full Interface. When Lane Full Interface is used on the most downstream zone; the input signal is treated with a block and clear timer such that when the signal is energized, the signal must remain energized for the “block” timer duration. When the block timer expires, then the zone is set to accumulate. Similarly, when the signal is de-energized, the signal must remain de-energized for the “clear” timer duration. When the clear time expires, the zone is set to release as normal. The Lane Full Interface also disables the Arrival Jam detection logic such that no arrival verification signal from downstream is required. This means that if the signal is off (and the clear time has expired) items arriving at the most downstream sensor will immediately release.
|Assuming the most downstream zone is connected to the right side of the module; we set the Right Aux I/O Pin 2 to Lane Full Interface from the drop-down box and make sure we click the “DOWN” arrow to indicate that the Right Pin 2 signal is to be associated with the Downstream Zone. The signal must be energized for the Block time period before cartons will stop and accumulate and the signal must be de-energized for the Clear time period before cartons will be allowed to release. In this example, we entered 5 seconds for the Block Time and 6 seconds for the Clear Time|
