System startup

When initially powered up, the Language, Date Format and Date/Time
screens appear in order. After these options are set, the controller
performs a device scan and displays the message Scanning for devices.
Please wait... If a new device is found, the controller performs an
installation process before displaying a main measurement screen.
If the scan finds previously installed devices without configuration
changes, the main measurement screen of the device in the number one
position appears immediately after the scan is complete.
If a device has been removed from the controller or is not found during the
next power-cycled or menu-driven scan, the controller displays a Device
missing message and prompts to delete the missing device.
If no sensor is connected to an installed analog module, the controller will
indicate an error. If devices are connected but not found by the controller,
refer to Troubleshooting on page 20.
Set the language, date and time for the first time
The controller displays the language, date and time edit screens when the
controller is powered on for the first time, and when it is powered on after
the configuration settings have been set to their default values.
After the language, date and time options are set for the first time, update
the options as necessary through the sc200 Setup menu.
