Setup
After the installation of the unit in a PLC system, the following initial setup
procedure must be executed:
• A unique unit number must be set. Refer to section 2-3-2-1.
• An I/O table must be created in the PLC, to register the unit on the PLC
CPU. Refer to section 2-3-2-2.
This initial setup procedure makes sure that the unit can start up properly and
can be configured for operation.
2-3-2-1 Setting the unit number
To set the unit number, perform the following steps:
1 Turn off the power supply to the PLC system.
2 Use a small screwdriver to set the unit number selector switch to the new
unit number.
Note
The maximum current consumption of the CJ1W-MCH72 is 680 mA. Make sure that the
total current consumption of all units connected to the same CPU backplane or expan-
sion backplane is not greater than the output capacity of the Power Supply Unit.

Note
If the sliders are not properly locked, it is possible that the unit does not operate cor-
rectly.
Note
Communication errors can occur in the Encoder Interface when Contact Output Units
are installed close to the CJ1W-MCH72. This is caused by noise generated by the Con-
tact Outputs.
If Contact Output Units and a CJ1W-MCH72 are installed on the same rack and com-
munication errors occur, do one of the following:
•
Install the Contact Output Units at maximum distance from the CJ1W-MCH72.
•
Use surge absorbers for the Contact Outputs.
