GENERATION NITROGEN GENERATOR SYSTEM MANUAL
CLIMATE CONTROL
As soon as electrical power is supplied to the Generator system, the cool air stream blower will start to
operate. The blower will run continuously so that the controller can monitor the enclosure's internal
temperature. The enclosure temperature will be displayed on the face of the controller.
If the enclosure temperature is greater than the factory cooling set point of 80°F, the "Cool" status LED will
flash. This indicates that the coolant compressor's automatic off cycle timer is working. The off cycle timer is
factory set at 3-1/2 minutes. At the end of 3-1/2 minutes, the coolant compressor and the condenser air
blower will begin to operate. This signifies that the cooling system has begun operation to remove heat and
humidity from the enclosure. This procedure may take 20 to 30 minutes before it reaches full capacity.
When the temperature inside the enclosure decreases 7°F below the "Cooling on" set point, the coolant
compressor and the condenser blower will cycle off. The cool air blower will continue to operate, circulating
air within the enclosure. The controller has a factory programmed temperature differential of 7°F.
Example: "Cooling on" @ 80°F; "Cooling off" @ 73°F.
The climate control system also provides power to three external heaters which are mounted in various
places within the equipment enclosure. If the enclosure temperature is below the factory heating set point of
63ºF, the heat status LED will be '"on". This indicates the heat relay has been energized and is providing
power to the three 400 watt heaters (no time delay exists before heating begins). When the temperature of
the enclosure rises 7°F above the set point, the controller will de-energize the heat relay and cycle the
heater "off".
NOTE: There is a deadband programmed into the controller that prevents heating and cooling from
operating simultaneously.
PROGRAMMING THE CONTROLLER
The controller has been programmed at the factory
with typical default settings for immediate system
operation. Please review the following default settings:
1) Cooling system on temperature
2) Heating system on temperature
3) High enclosure temperature alarm 105° F
4) Low enclosure temperature alarm 40° F
5) Audible and Visual alarm
6) Digital display in degrees
7) Filter maintenance alarm
8) High condenser temperature alarm 170° F
