I.2 STAND ALONE CONTROL PANEL (AUTOMATIC
OPERATION)
WHEN AMBIENT TEMPERATURE FALLS BELOW 38°F:
1.
Snow or blowing snow exists.
2.
Fastrax
®
FDC-6/FDC-7 automatic snow sensing
integrated control and sensor system initiates to full
power heater operation.
3. When full power is applied the green “Full Power On”
indicating light will be illuminated.
4. The integrated control and sensor system will continue
to monitor the environment until no further snowfall is
detected or the ambient temperature rises above 38°F.
5. After snowfall stops a timer holds full power on for a
period of 1-99 hours (adjustable by customer or default
adjustment of 5 hours). Two types of snow sensors are
supplied as standard equipment.
a)
FAS1A aerial snow sensor assembly (field
installed above panel).
b) FGSP1A ground snow sensor assembly (factory
installed in FJAM200SUP junction box).
These snow sensors include a preset 38°F temperature
control, a low voltage heater to melt falling snow, and a
moisture/snow sensor.
The FDC-6/FDC-7 control system has the ability to accept
as many sensors as desired wired to the master control. Any
combination of the above sensors may be used. The worst-
case location will then turn the system on.
6. After full power time has elapsed the green “Full Power
On” indicating light will go off.
7. After 5-7 seconds an energy saving heater circuit
energizes, the green “Reduced Power On” indicating
light will illuminate, and maintains the rail heaters at
25% of full power to maintain heating of residual or
blowing snow.
8. Crib heaters and SwitchBlade
®
heaters for the spring
frog and movable point frog maintain full power during
this period.
Note: At any point during the hold time operation
(either full or 25% power maintenance cycle) if new
snow falls and the ambient temperature falls below
38°F, the automatic control is re-initiated and full
heating operation starts over.
Note:
On control panels heating 3 or more switch
assemblies, the heaters are sequenced on in 4 steps
with a 10 second delay between heaters coming on.
