The ice detector has a heating element which will
de
−
ice the detector in a cyclic manner. When the
frequency of vibration is sensed to be at a ”no ice”
level the heating is switched off, the ICE COND in-
dication light is extinguished and a new ice detec-
tion cycle is started. If the ENG ANTI
−
ICE has been
switched ON previously, and remains ON, the blue
status lights will remain steady, i.e. the flashing is
suppressed.
The ice detector is powered from R AC GEN BUS.
IT IS VERY IMPORTANT TO UNDERSTAND
THAT THE ICE DETECTOR ALERT SHALL
NOT BE USED AS THE CUE FOR SWITCHING
ON ENG ANTI
−
ICE. THE ICE DETECTOR
FUNCTION SHALL BE CONSIDERED AN
ALERT SHOULD ICING CONDITIONS BE EN-
TERED UNNOTICED FOR ANY REASON.
