6.4. Hard-Wired Interlocks

Once your linear conveyor has been Auto-Configured and running in ZPA mode; the ConveyLinx Modules will attempt to convey all items from upstream to downstream in the direction of flow. The next logical step that you will want to do is Interlock with the most upstream and/or downstream zones and perhaps interrupt flow in a zone somewhere in the middle.

Control Ports Provide Interlock Function

By default after configuration, each control port provides:

• An input for an Interlock Signal (Pin 4)
• An input for Local Zone Accumulate (Pin 3)
• An output that indicates if zone is occupied (Pins 1/6 Circuit)
  

*The Interlock Input (Pin 4) will act as either a Wake Up or a Lane Full depending on whether the Control Port is configured on the Upstream or Downstream side of the module. When each ConveyLinx Module has been Auto-Configured, either its Left or Right side will be configured as the Upstream side and the other will be the Downstream side depending on the flow established during Auto-Configuration.

!Wake Up interlock should only be used on the MOST Upstream zone and the Lane Full interlock should only be used on then MOST Downstream zone of any given subnet.
