4 Operating the Generator

4.1 Overview of the Controls

4.2 Starting the generator

1 Inspect all of the system connection points and verify that they are secure.
2 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.
3 Switch the electrical power on to the generator and wait whilst it runs through the controller initialisation routine.
4 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.
5 Press to initiate the start up routine.
If the start clean up option is enabled the generator will run through the Rapid Cycle before opening the
buffer valve and the N2 outlet valve. The clean up cycle, which takes approximately 160 seconds, is
designed to clean the CMS bed of impurities, bring the generator up to production purity more rapidly, and
prevent poor quality gas flowing into the buffer.
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 for ppm
generators.
6 Partially open the ball valve on the inlet to the buffer vessel to allow it to pressurise slowly. When the pressure gauge on the buffer vessel
reads within 0.5 barg (7psig) of the inlet pressure, check for leaks in the buffer vessel inlet piping and then fully open the ball valve.
7 Open the ball valve on the outlet of the buffer vessel and check for leaks in the piping between the vessel and the generator.
8 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.
