rain sensor remains in an icing environment. The ice signal activates at
0.5mm ice accretion and stays on for 60 seconds after the end of the icing
encounter. Specifically, when the output is activated, a 60-second timer is
started. Each time 0.5mm forms on the probe, the 60-second counter is
reset. In effect, the output stays on for 60 seconds after the beginning of
the “last” icing encounter.
The Status output indicates whether the freezing rain sensor is
functioning correctly using tests that are described in more detail in
following sections of this document.
