Sensoface
(Sensocheck must have been activated during configuration.)
The smiley in the display (Sensoface) alerts to sensor problems
(defective sensor, defective cable, maintenance required). 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 leads for short circuits or open
circuits. Critical values make the Sensoface “sad” and the correspond-
ing icon blinks:
The Sensocheck message is also output as error message Err 15.
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.
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.
