2.Insert the memory module. Note: this step can be preformed while the unit is powered, however care should be taken not to contact any wiring within the control cabinet.

3.Cycle power to the control cabinet allowing approximately 30 seconds for the DC power supply (if provided) to fully discharge.

4.After approximately 30 seconds, the PLC’s green RUN indicator will flash indicating the PLC is reading the memory module. When complete, the PLC will automatically begin operation and the RUN indicator will be on solid.

5.Note that re-loading the memory module will restore ALL settings to their factory default values and the settings will have to be re-entered manually.
