4.2 Cable Connection
The recommended cabling diagram for MBS-C INPUT/OUTPUT signal is shown in Figure 4-3.
Please refer to Figure 4-4 and 4-5 as well.
In Figure 4-4, cabling using MBD is shown. In this example, MBS compatible cables that
enables the similar wiring with existing models of MBS.
In Figure 4-5, the wiring using MBD-MBS-C connection cable (Option of MBD-HS30) that can
connect MBD and MBS-C directly and is normally recommended.
Disconnect the power supply to MBS-C before connecting the cables to devices, there is a
risk of electric shock when touching the connectors.
If you connect and disconnect the cable without turning off MBD or other connecting devices,
MBS-C's factory default values may be overwritten and MBS-C function incorrectly. .
(*1) After all connections have been made, reconfirm that cables are connected correctly.
Missed wiring may cause damage to MBS-C.

Missed wiring may cause damage to MBS-C.
(*2) The isolation between ANALOG IN and 24V P/S in the control panel is recommended to
reduce noise problem.

reduce noise problem.
(*3) Also, isolation between DIGITAL IN and ANALOG IN is recommended for the same
reason, and avoiding Ground-Loop problem.

(*4) In case of connecting a measureme S-C analog output line, check the
tool’s input impedance before the connection. Lower impedance may cause a voltage
drop of MBS-C analog line, and may damage the system operation.

thermocouple plug cables. The temperature will not be measured correctly with regular
signal cables.

WARNIN
When Wiring;
In order to prevent mutual interference during operation, signal lines, control lines, and AC
power lines should be placed in separate conduits. Especially, do not route MBS-C analog line
in ways as to place together with AC power lines or control lines of other equipments in a same
conduit, or to bundle them together. It may cause interference with MBS-C operation.
In case that separated conduits are not possible, keep enough distance between the lines
(300mm or more) to avoid the interference.
