GENERATION NITROGEN GENERATOR SYSTEM MANUAL
START-UP (continued)
7) Verify that the climate control internal fan is operating and climate control interface is energized.
8) Verify storage tank pressure. If tank is empty or below 100 psi, the air compressor should immediately
start and run for approximately 5–7 minutes. NOTE: A strong hissing sound will be heard for the first
2–3 minutes as the nitrogen is diverted to atmosphere before being brought to full purity.
9) Close generator door and wait for enclosure temperature to be brought within specifications.
10) After compressor charges the storage tank and shuts off, perform a continuity check on the following
alarms contacts:
a) Terminals 1 to 2 – OPEN
b) Terminals 4 to 5 – OPEN
c) Terminals 11 to 12 – OPEN
11) Open the outlet valve. Compressor will cycle as storage tank drains to 100 psi. Compressor shut-off is
110–125 psi. Typical runtime is 5–10 minutes, depending upon altitude.
12) Rotate the regulator panel bypass valve from full regulation to bypass operation.
13) Open the return valve.
14) Close the generator door and latch.
15) Purge for the calculated amount of time based upon 5 liters per minute flow rate.
16) Close return valve.
17) Change regulator panel bypass valve from bypass mode to full regulation mode. This will maintain the
gas space from 0.5 psi to 5 psi.
IMPORTANT: Check all pipes and connections for leaks using soap or leak-tracing spray. Any
leakage will reduce capacity considerably.
PROPER SYSTEM OPERATION CHECKS
1) During air compressor run and with outlet valve shut, check membrane outlet gauge (on top of storage
tank) and verify that the pressure rises above 130 psi. If not, leaks exist between the compressor and
storage tanks or the inlet carbon filter and compressor filter may be clogged.
2) Verify that compressor turns on at 90–100 psi and turns off at 110–125 psi. If not, readjust.
NOTE: In higher altitude locations, the pressures may need to be adjusted to the low side of
specifications.
3) Verify that the nitrogen storage system is not leaking. With generator outlet valve shut and the air
compressor off, verify that no decrease in pressure takes place on the nitrogen regulator module gauge.
If a decrease is present, the one-way valve, storage tank or nitrogen regulator module may be leaking.
4) Verify during compressor run that the coalescing filter purges the collected water and reseals during the
next compressor run. The oil sump drain can be used to speed the cycling of the air compressor.
5) At each compressor start, verify that the solenoid valve diverts to atmosphere. At each start, a strong
hissing sound will occur for two minutes. If not, the solenoid valve may have failed. If the hissing sound
is heard for less than or longer than two minutes, the solenoid timer is misadjusted. Push the
corresponding buttons on timer to display 110 (seconds).
