At a minimum, to interlock or “Wake Up” the most upstream ZPA zone, the upstream zone’s Input Interlock signal must be used. For a complete “Handshake” where the Non-ConveyLinx controlled feeding conveyor requires the block or clear status of the most upstream ZPA zone; both the Input Interlock and Output Interlock signals must be used.

Upstream Interlock Definition

For powered and controlled (PLC or otherwise) non-ConveyLinx discharging conveyor, the following image depicts a typical interface and the signals required.

Singulated Transfer to Most Upstream ZPA Zone

Because the Output Interlock is OFF indicating PE1 is clear, when PEx is blocked, the Discharge Conveyor controller energizes its Conveyor Output Signal to energize the ConveyLinxモジュール Interlock Input . This causes Zone 1’s motor to run
Zone 1’s motor will continue to run as long as its Interlock Input is ON. The Discharge Conveyor can run or stop its motor as needed once its PEx is clear
When PE1 becomes blocked, the ConveyLinxモジュール stops Zone 1’s motor and energizes its Interlock Output which in turn energizes the Conveyor Input Signal indicating that PE1 is blocked
As long as PE1 is blocked; the ConveyLinxモジュール will keep its Output Interlock energized to signal the Discharge Conveyor to stop its motor if and when PEx becomes blocked

Here is a timing diagram for the operation

!The most upstream zone’s motor will continue to run as long as the Interlock Input signal is energized and its zone sensor remains unblocked. If the signal is removed, the zone will continue to run for Jam Timer setting (5 seconds by default) and then stop
