Operating the Generator EN

4.2 Starting the generator
Inspect all of the system connection points and verify that they are secure.
With both the inlet and outlet ball valves of the buffer vessel closed, open the ball valve on the air inlet port to allow the compressed air into the
generator.
Switch the electrical power on to the generator and wait whilst it runs through the controller initialisation routine.
Slightly open the ball valve on the inlet to the buffer vessel and leave it to pressurise slowly. When the pressure gauge on the buffer vessel reads
within 0.5 barg (7psig, 0.05MPa) of the inlet pressure, check for leaks in the inlet piping and then fully open the ball valve.
Open the ball valve on the outlet of the buffer vessel and check for leaks in the piping between the vessel and the generator.
Open the ball valve on the Nitrogen outlet.
Note: If the purity of the gas is not within specification it will be vented to atmosphere through a vent solenoid within the generator and not
delivered to the application. When the required purity is achieved the gas will be delivered to the application.
4.3 Stopping the generator
Close the ball valve on the N2 Outlet port.
If the generator was in standby mode when the electrical power was removed it will default to standby
mode on completion of the initialisation routine.
Press to initiate the start up routine.
If the start clean up option is enabled the generator will run through the Rapid Cycle / Pure Start
before opening the buffer valve and the N2 outlet valve.
[Refer to section 4.5 for more details on Rapid Cycle and Pure Start]
If the generator was running when the electrical power was removed (e.g. power failure) it will
automatically run through a start up cycle (if enabled) and then commence normal operation. Wait
until this cycle is complete and the menu displays “Running”. This may take several minutes in ppm
generators.
Press [ ] to initiate the shutting down sequence.
The generator will complete the current cycle and then exhaust both beds. This may take several
minutes particularly on ppm generators.
When the generator is depressurised it will revert to standby mode.
Note: There may be a residual pressure of approximately 1.5 bar within the columns due to the
release of oxygen from the CMS. This can be released by turning the Kaddis drain, or small ball valve
if fitted, on the inlet valve assembly.
