Upstream Interlock (Wake Up)
Interlock with the most upstream zone to get an input to see if is clear and then turn on an output (Wake Up) to tell it to run to accept a new item
Whichever Control Port (Left or Right) is on the Upstream Side of the module will accept a Wake Up signal input on its interlock input Pin 4. If the zone is unoccupied, when a digital signal is applied to Pin 4, the zone will run its motor to accept an item.
- When NOT to use Pin 4 as a Wake Up
Only use the Interlock Pin 4 signal for Wake Up on the most upstream zone of a network. Do not use the Pin 4 signal on any of the other zones on modules with an upstream connection to another ConveyLinx-ERSC Module – You may get unexpected results because signal may or may not over-ride the status coming from upstream over the network.

- Wake Up Interlock with Handshake
-
The external controls providing the Wake Up signal to Pin 4 will sometimes also require an output signal from the ConveyLinx-ERSC Module that will indicate when this upstream zone is occupied in order to implement a handshake. This zone occupied signal is provided by the Control Port’s output signal.
Upstream Control Port Output is OFF and PLC signal to Upstream Control Port Pin 4 is OFF. When Carton 1 reaches PLC connected PEx, the PLC energizes its output signal to Upstream Control Port Pin 4 and Zone 1 Motor starts to run ![]()
When Carton 1 clears PLC connected PEx, the PLC turns off its output signal to Upstream Control Port Pin 4 ![]()
When Carton arrives at Zone 1 PE1, the Upstream Control Port Output is ON to indicate that Zone 1 is occupied. The PLC can connect this signal to a digital input to use in its logic to stop its conveyor if another carton arrives at PEx ![]()
