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 the
Troubleshooting section of this manual.

The controller displays the language, date and time edit screens when the controller is powered on
