Bellows Cycles and Travel
The Bellows Cycles and Travel page allows you to set warning limits related to the number
of bellows cycles and the bellows travel. The cycles and travel are recorded by the
positioner during normal operation. These limits affect the health bar indicator on the
Dashboard. For example, as the bellows cycles increase and pass the Initial Warning, the
health bar will begin to turn yellow. As it approaches the Final Warning. the health bar will
be completely yellow.
