9.1 - Control diagnostics
Touch Pilot control system has many fault tracing aid functions,
protecting the unit against risks that could result in the failure of
the unit.
The user interface enables the quick display of the unit status:
- The blinking bell icon indicates that there is an alarm, but the
unit is still running.
- The highlighted bell icon indicates that the unit is shut down
due to a detected fault.

monitor all unit operating conditions. If an operating fault is
detected, the alarm is triggered.
All information regarding the existing alarms (current and past
alarms) can be found in the Alarms menu.
