In situations where the full status of a given merge line needs to determine merge priority, ConveyMerge provides
the ability to monitor the status of one or all merging lines and base the release priority accordingly. EasyRoll
provides the option to select a given upstream zone on a given line and the Monitor Zone . When the Monitor Zone
becomes occupied for a given time value; its line will be given release priority into the Merge Zone . There are two
adjustable time values for this function:
EasyRoll Selection Description
Block Timeout
Specified the amount of time the Monitor Zone must be occupied before the
Monitor Zone’s line will receive priority to release into the Merge Zone. This
timer starts when the Monitor Zone first becomes accumulated (sensor blocked
and motor stopped) and continues to time as long as the Monitor Zone stays
accumulated.
Clear Timeout
Specified amount of time that the priority release will continue to be active
once the priority release has begun. When this time value expires, the priority
setting will return to its original
EasyRoll configured setting.
If multiple lines are configured for Dynamic Priority and each of their respective Block
Timers have expired;
ConveyMerge logic will revert to the First Come First Serve release
mode until one or more of the releasing lines’ Clear Timer has expired.

Please refer to Figure 13 for this example. In EasyRoll , Node 2 upstream zone of the Central Line has been selected
as the Merge Zone and the merge type is Up Left . The EasyRoll setting for priority is Center Line Priority . Also in
EasyRoll , the Merge Line Full function has been enabled as assigned to Node 3 downstream zone of the Left Line.
As shown in Figure 13, assuming we did not enable the Merge Line Full function for the Left Line; if there is a steady
flow of product on the central line; the Left Line will never be able to release because the central line was set as the
default line for priority in
EasyRoll . Now, with the Merge Line Full feature enabled on the Left Line; once Left Line
Node 3 downstream zone remains accumulated for the Block Timer’s timeout; priority will dynamically change to
the Left Line. This Left Line priority will remain in effect until the Clear Timer’s timeout has expired. When this
occurs, the priority will automatically revert to the EasyRoll configured priority (center line in this example). Figure
14 illustrates the Clear Timeout function.
