Sensoface
(Sensocheck must have been activated during configuration.)
The smiley in the display (Sensoface) alerts to sensor problems
( defective sensor, sensor wear, defective cable, maintenance request).
The permitted calibration ranges and the conditions for a friendly,
neutral, or sad Sensoface are summarized in the following table.
Additional icons refer to the error cause.
Sensocheck
Continuously monitors the sensor and its wiring.
Critical values make the Sensoface “sad” and the corresponding icon
blinks:
The Sensocheck message is also output as error message Err 15 (glass
electrode) or Err 16 (reference electrode – for digital transmitters,
however only with InduCon sensors with SG). The alarm contact is
active, the display backlighting turns red, output current 1 is set to
22 mA (when configured correspondingly).
Sensocheck can be switched off during configuration (then Sensoface
is also disabled).
Exception:
After a calibration a smiley is always displayed for confirmation.
Please note:
The worsening of a Sensoface criterion leads to the devaluation of the
Sensoface indicator (Smiley becomes “sad”). An improvement of the
Sensoface indicator can only take place after calibration or removal of
the sensor defect.
