The CS1W-LCB01 and CS1W-LCB05 Loop Control Boards are mounted in
the Inner Board slot of a CS1-H CPU Unit. Only one Board can be mounted in
each CPU Unit.
Note 1. Loop Control Boards before version 1.5 cannot be used with CS1D-
CPU@@S CS1D CPU Units for Single-CPU System.
2. Always turn OFF the power supply before mounting or removing the Board.
If the Board is mounted or removed with power supplied, the CPU Unit may
malfunction or internal elements may be destroyed.
3. Before handling the Board, touch a grounded metal object to discharge
static electricity from your body.
Process-control CPU
Units (CS1D-CPU@@P)
Duplex Loop Control Boards are already mounted in the Process-control CPU
Unit (CS1D-CPU@@P).
Normal operation will be possible only if the CS1D CPU Unit is used in the
combination in which it was shipped.
!WARNING Do not remove the Duplex Loop Control Board (Inner Board) from the CS1D-
CPU@@P CS1D Process-control CPU Unit. Normal operation may not be
possible if the Board is removed.
