10.1 Sensoface
The Sensoface feature is active whenever Sensocheck is active. This
feature monitors the sensor for defects in the sensor or cable, and
indicates the maintenance status of the sensor (see
Table 15 ).
10.2 Sensocheck
The Sensocheck feature monitors the primary and secondary coil for
short and open circuits. When problems are detected, the error
message “Err 33” (“Err 34”) is displayed, along with an icon
corresponding to the type of problem (see
Table 16 ).
Sensocheck can be switched off during configuration and Sensoface is
also disabled.
Note: For confirmation a sensoface is displayed after a calibration
setting.
