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 24.
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 setup menu.

3. In the DATE/TIME screen, push the right or left arrow keys to highlight a field, then push the up
and down arrow keys to update the value in the field. Update the other fields as necessary.
4. Push the enter key. The changes are saved and the controller performs a start-up scan for
devices. If connected devices are found, the controller displays the main measurement screen for
the device in the number one position. If the controller fails to find connected devices, refer to
