10.2 Removing the XL7 OCS I/O Cover

Some I/O configurations require jumper settings to be changed in the XL7 OCS unit. Examples of these

settings are setting positive or negative logic on digital inputs or setting current or voltage on analog

inputs.

Each XL7 OCS I/O jumper is set to a factory default. Refer to the XL7 datasheet to find the default

setting to determine if a jumper change is necessary for a particular application.

To remove the I/O cover of the XL7 OCS, remove the four (4) Phillips screws from the I/O back. It may

help to place the XL7 OCS unit face down on a clean work surface. Once the four screws are removed

the I/O cover can be lifted straight off.
