HEATER CONTROL
The AutroPath HC800 optics in both transmitter
and receiver are heated to provide moisture and
ice resistance. These heaters are microprocessor
controlled and can be configured to operate in the
following modes:
– Always On
– Always Off
– Smart Mode (default)
1) Heaters maintain a user programmable temperature
set point (default = 50°C).
2) Heaters increase to full power when signal strength
is degraded due to moisture or condensation on the
window, or any obscuration faults are active.
3) Heaters shut off when the input voltage drops below
a user defined level (default = 18.5 Vdc).
4) Heater power usage can be limited from 0-100%
(default uses up to 100% power if needed). See
Specifications section for power consumption
details.
Table 6 indicates the typical window glass temperature
rise for various heater setting and ambient temperature
combinations.
NOTE
Higher heater settings reduce or eliminate
moisture buildup on the window, thereby
providing optimum detector performance.
