3.1.6 NCC-002 Controlling a Bottle Heater
Use this diagram to provide programmable closed loop bottle heater control using the nitrous pressure sensor.
NOTE: Each terminal on the NCC-002 controller is capable of connecting to 2 separate wires at a time. If there
are more than two wires going to a single terminal (as may be the case with the sensor ground terminal), splice
the incoming wires together. Another option is to purchase a barrier strip adapter that increases the wire
capacity of the single terminal.
WARNING: If the nitrous pressure sensor is located on the tank side of your nitrous bottle valve, the
valve can be closed between runs as the sensor can still sense the bottle pressure while it is being
heated. If your nitrous pressure sensor is located on the outgoing side of your valve, the valve must
stay open anytime the bottle is being heated so that the nitrous pressure sensor can regulate the
pressure. Heating the bottle with the pressure sensor on the outgoing side of the valve and the valve
shut could potentially cause an extremely dangerous over-pressure condition. Per NHRA rules, the
bottle's over-pressure safety disk should be connected to a blow down tube that allows nitrous to be
vented out of the vehicle in the event that the safety disk ruptures. Before using the nitrous bottle(s),
make sure that they are properly secured to the vehicle. If using a bottle heater, make sure that the
bottle heater is properly secured to the bottle and that it lays completely flat around the bottle.
•
Connect the solid red wire labeled "12 VOLT PWR" to the "+12 Volt" terminal on the NCC-002 and to a fused
and switched 12 volt DC source.
•
Connect the solid black wires labeled "GROUND1" and "GROUND2 to the "Ground1" and "Ground2"
terminals on the NCC-002 and to the battery ground stud.
•
Connect the solid orange wire labeled "RELAY2 12V" to the "Relay2 Out, +12V" terminal on the NCC-002 and
to the bottle heater relay input.
•
Connect the output of the relay to the input for the bottle heater. Make sure to follow the bottle heater
manufacturer's instructions.
•
Using the Nitrous Pressure Sensor Harness, connect the nitrous pressure sensor harness connector to the
nitrous pressure sensor. Then, connect the solid white wire labeled "NITROUS" to the "N2O PSI Input"
terminal on the NCC-002, the solid red +5 volt wire to the "Sensor +5V" terminal on the NCC-002, and the
solid black ground wire to the "Sensor GND" terminal on the NCC-002.
•
A temperature switch can also be added for additional protection.
•
Program the Relay2 Out for nitrous pressure control.
