Start-up Sequence
CHECK:
1.
Transport plugs have been removed
2.
H2 Outlet is connected to application
3.
Mains power is connected
Turn the power switch ON. The digital display will light up, the cooling fans will
rotate and the internal pumps may automatically run to load water if the
internal tanks are not full.
On power up the generator performs a diagnostic check including a leak test,
this should take approximately six minutes.
Upon successful completion of the leak test, the operator is presented with the
main screen and the generator is ready to deliver hydrogen.
The next screen displayed to the user will be the Home screen, where two
options will be available, Start and Menu. The first time the unit is switched on
the user should select the Menu option which allows the desired Unit of
measure and delivery pressure to be selected.
Also displayed on this screen are the Shutdown and Back options. Shutdown
will depressurize the generator. This should be selected before turning the unit
off using the Power switch at the rear of the unit. Finally, the Back option
returns the user to the home screen
where the Start option will allow the flow
of hydrogen to the application.
Upon selection the unit will take a few moments to adjust to the desired
delivery pressure. If the unit has been used previously the Start button will
initiate the supply of hydrogen to the application at the last used pressure.
Note: If leak test is unsuccessful, and alarm will sound and a red failure screen
will be displayed complete with a mute button. The user is prompted at this
point to contact their Peak service provider.
Liquid Leak Detectors
Liquid leak detectors should not be used on the Precision 500. These solutions
are easily drawn into the high purity hydrogen gas system and can cause
irreparable damage to a GC column. If a liquid solution has to be used, then it
should be IPA based, or a portable hydrogen detector should be used.
