Figure 4-1 Wiring Of Mbd-S/Mbd-T And Mbs-C - Ulvac MBD Series Instruction Manual

CRYO METER MBD series Instruction Manual
◆Wiring
After the MBD has been installed to the panel, connect the MBD to the MBS-C. [MBD -
MBS-C connecting cable (MBD-HS30)] can be used for connecting MBD to MBS-C
POWER and ANALOG OUT (I/O connectors). In this case, wiring of MBS-C RELAY and
K(CA) needs to be done by users. (Refer to the dotted lines in the diagram below.)
To choose other cables, please refer to the Table 1-2 or appendix 2 in MBS-C instruction
manual. The [MBS-MBD connecting cable] will be required to connect the MBD-S/MBD-T
to existing MBS. Please specify the cable at time of order. The wiring of MBS and
MBD-S/MBD-T is shown in Figure 4-2.

Conduit Requirements for MBD wiring
To prevent interference during the operation, there should be a separate conduit for each signal
line, control line and AC power line. Especially ANALOG signal line of MBS-C must be in
separate conduit from other equipments or AC power lines or control lines for other equipments.
Otherwise, MBS-C operation will be interfered.
If separate conduits cannot be supplied, keep enough distance (generally 300mm or more)
between different wirings. It is effective to prevent interference.
