# E-stop source from button connected to first FlexCarrier

In this mode the first FlexCarrier in the daisy chain is used as a primary FlexCarrier. Connect an e-stop entry plug in the first FlexCarrier. If more FlexCarriers are connected in a daisy chain, connect a bypass plug in each of the following FlexCarriers. The bypass plug is used to signal that the chain is correct.

All FlexCarrier must have a plug otherwise the e-stop function will prevent the FlexSystem to start

For the system to work, an e-stop and a reset button needs to be connected to the entry plug.

1. First FlexCarrier with e-stop entry plug

2. Second FlexCarrier with bypass plug

3. Third FlexCarrier with bypass plug
