It is common for an operator to un-thread the coil to clear a Jam and then re-thread the same coil. As a convenience, the Unload Coil window has a "Coil was NOT Unloaded" button to handle this occurrence. This allows the operator to continue on without having to look up and re-enter the coil number.

The screen has been changed to prevent the operator from selecting the "Coil was NOT Unloaded" button until a coil is sensed by the Tail-Out input. If the Tail-Out input is ON the only appropriate responses are "Return Coil to Inventory" or "Coil was Completed".

There is an exception to this rule that should rarely come into play due to the unlikely nature of the situation to occur. After a tail-out, if a coil number gets entered with a barcode macro or the production screen and an operator then mistakenly tries to enter a new coil or delete the current one, they are given the opportunity to change their mind and select "Coil was NOT Unloaded" regardless of the Tail-Out state.
