Figure 19: Connection examples for operation in a CES-AR switch chain
For detailed information on operation in an AR switch chain, see the related CES-AR operating instructions. The
locking module MGB-L1-AR-…/MGB-L2-AR-… behaves in the switch chain in practice like a safety switch CES-AR.
The differences to the CES-AR are described in the following.
