BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual page 307

Failure of any of the other five heaters is in-
dicated by illumination of the HTR FAIL light
on the ADS heater control panel.
Illumination of either PITOT HEAT light or
the HTR FAIL light is accompanied by illu-
mination of the ANTI-ICE annunciator and the
flashing MASTER CAUTION lights.
When the HTR FAIL light illuminates, the ro-
tary PWR & METER SELECT switch must be
rotated through each position until the failed
heater is detected by reference to the % HTR
CURRENT meter. When the meter pointer
falls into the red zone (less than 40%), it shows
that the selected heater is faulty.
All failure indications, except those associ-
ated with the pitot-static probes, may be can-
celed by pressing the HTR FAIL switchlight.
Failure warning for the pitot-static probes can-
not be canceled.
Resetting the HTR FAIL switchlight allows it
to indicate another failure if it occurs.
