After the initial start-up cycle (5 hours) has been completed, the “System Check” LED will go
off and the “System Ready” LED will illuminate. Open the external outlet valve and the gen-
erator will supply ultra high purity nitrogen to the application. Check all downstream piping
connections for leaks using a bubble-type leak detecting solution.
If there is a power or pressure interruption, the “System Check” LED will go on and the sys-
tem may go back into a start-up mode. (See “Power Interruptions” and “Pressure Interrup-
tions” sections below). If the “System Ready” LED indicator goes off and the “Service System”
LED indicator is illuminated or blinking, the operator should check the hydrocarbon catalyst
module (Model UHPN2-1100 only). It may need to be replaced as part of the normal mainte-
nance of the hydrocarbon catalyst module, or it may have a loose electrical connection (see
the Troubleshooting Section at the end of this bulletin).
If the compressed air pressure falls below 60 psig (4.1 barg), an internal pressure transducer
will activate an audible alarm and the yellow “System Check” light will be illuminated to
attract operator attention. If the pressure remains below 60 psig (4.1 barg) for less than 6
minutes (time required for purge and fill of PSA towers), the system will continue to operate
at rated flow and purity. If the inlet air pressure drops below 60 psig (4.1 barg) for more than
6 minutes, the internal outlet valve will close and the flow of nitrogen will cease. After this
low pressure condition is corrected, the outlet valve will open and the nitrogen flow will start
again immediately.
If the electrical power is interrupted for less than 30 minutes, the system will deliver nitro-
gen at rated flow and purity when the power returns. If the power is interrupted for between
30 and 60 minutes, the generator will go into an abbreviated 1 hour start-up cycle when the
power returns. If the power supply is interrupted for more than 1 hour, the initial 5 hour start-
up cycle will be repeated when the power returns.
The flow of nitrogen from the Parker Balston Nitrogen Generator must be controlled using
a metering valve or flow controller downstream from the unit. The flow control device may
be integral to the equipment being used downstream, or it may be an independent controller
(see Installation Section) purchased and installed by the customer. In either case, a device to
measure the flow should also be installed (either with the flow controller or downstream from
the application). If the demand of ultra high purity nitrogen exceeds the delivery capacity of
the generator, the purity and pressure of the emergent nitrogen stream will not meet specifi-
cations.
The outlet pressure and flow from the generator must be adjusted according to the operating
parameters listed below. If the outlet flow exceeds the rated flow for a given inlet pressure,
the nitrogen purity will not meet specifications.

Outlet Flow Operating
Parameters
If the generator will be shut down for longer than a few hours, turn off the power to the gen-
erator and close the (customer installed) inlet air valve. Allow the generator to purge for 10
minutes. Open the lower service panel and close the 2-way manual valve upstream from the
PSA towers (see Figure 5). Finally, close the external manual outlet valve.
If the generator is
not shut down according to this procedure, the PSA towers may be poisoned and the war-
ranty will be void.

Flow Rate Adjustment
* Note: During the warmup, receiver pressure gauge reading will be zero.
