The lower four alarm indicators are tied to
numerical values and the current value is shown in
the white box.

If an alarm occurs, the touch panel display will
automatically bring up the alarm screen. You can
navigate away from the alarm screen but the
navigation buttons will flash after you do to
indicate that an alarm still exists. When the alarm
is reset the flashing stops.

The LOG button brings up a screen with a list of
alarm events.

You can scroll through the list after pressing
SELECT ALARM.
