System Forecast (Ceramat, SensoGate)
Monitoring the probe travel behavior of retractable fittings
(with Unical 9000(X) software version 4.3 or higher)
The "System Forecast" function
enables monitoring of the probe
travel behavior of the Ceramat or
SensoGate retractable fittings.
Possible signs of wear are detected in
good time to prevent failure or down-
times ("predictive maintenance").
Fittings frequently display signs
of wear as a change in their travel
behavior. The travel time can increase
significantly, for example, if aggres-
sive media or critical processes cause
the retractable fitting to become
sticky or seals to swell. The switching
behavior of control elements such
as piezo valves also changes in the
course of time, particularly with long
dwell times in one position.

The opening and closing times as well as the passing capacity of these valves
can then be significantly changed. Over time, pneumatically-controlled valves
are also subject to changed switching times as a result of increasing friction,
fatty deposits or other influences. The "System Forecast" determines whether
the probe movement is continuous or jerky, which, for example, would indicate
resinified fat. These changes can be recorded in a probe travel profile.

By comparing with reference times, an expert
can draw conclusions on the status of the sep-
arate components, and the system itself can
generate appropriate messages, see example
(menu "Diagnostics / Message list").
