2. Ensure that the machine controller (e.g. C220) is powered, and start the H212
in Config Mode as instructed above. Note that the initial display upon
entering Config Mode will include the message "< & > for Diagnostics".
3. Once in Config Mode, simultaneously press the left rectangular (<) and right
rectangular (>) buttons together, then release them.
When in Diag Mode, the left rectangular and right rectangular buttons may be
used to select one of several information pages for display. Pages contain live data from
the machine controller and may be useful during commission (to view input states) and
trouble-shooting (to view fault details). Other information such as the machine
controller's firmware revision are also available in Diag Mode. Pressing the green button
will toggle to (and back from) a legend display which explains the button functions and
fault code abbreviations.
