Start-Up Sequence
Before the Generator is connected to the application, the Generator
should be operated in isolation (i.e. not connected to the application)
for thirty minutes. This is to ensure any impurities present are purged
from the system. Failure to do this may harm the application.
With the generator installed as described earlier, connect power to the unit and
turn it on. Disconnect the Nitrogen outlet connection to allow the generator to vent
to atmosphere until the unit is stabilised. At Switch-on the exhaust valve will open
and the generator will commence its venting cycle. This is to allow venting of any
residual pressure in the system. The vent cycle may last up to 90 seconds. At the end
of the vent cycle, the inlet valve will open and the normal operating cycle will begin.
Pressure should begin to build on the gauge on the front panel, reaching 80 psi after
approximately 10 minutes.
The generator has been pre-set in the factory to give the specified output flow rate
and pressure. Once the pressure in the Nitrogen receiver exceeds that setting the
generator will stabilise and produce pure Nitrogen. Maximum purity will be achieved
after around 8 hours. After this time the generator can be reconnected to the
application.
The design of the generator is such that it will deliver up to the rated output flow of
Nitrogen at 80 psi. Should the demand for Nitrogen be less than the rated output flow,
or indeed should the demand stop, the generator will continue to operate without any
problems. The generator is protected from over-pressure and its normal operating
cycle ensures frequent venting.
