Sensoface
The Sensoface icons provide the user with diagnostic information on wear and required maintenance
of the sensor. In measuring mode, an icon (happy, neutral, or sad smiley) is shown on the display to
reflect the continuous monitoring of the sensor parameters.
You can configure the current outputs so that a Sensoface message generates a 22-mA error signal.

With Memosens sensors, also: Number of CIP and SIP cycles compared to the specified “Sensor Moni-
toring Details”.
