*1. The startup time is the delay time from power-on to when the SCC-1224A Safety Mat/Edge Controller is ready to
     operate.
*2. The operating time is the time it takes for the safety output contacts to be closed after the sensor is deactivated and the
      manual reset input contacts are closed.
      The contact bounce time is not included.
*3. The response time is the time it takes for the safety output contacts to open after the sensor is activated. Contact
      bounce time is included.
Note: The SCC-1224/SCC-1224ND have different specifications. Consult your OMRON representative for details.
