Start-Up Sequence
Before the Generator is connected to the application, the Generator
should be operated in isolation (i.e. not connected to the application)
for thirty minutes. This is to ensure any impurities present are purged
from the system. Failure to do this may harm the application.
Before re-connecting the Generator to the mains and switching it on for the isolation
run, it is necessary to fit the silencer to the outlet port of the output panel.
Once this is done, the Generator can be re-connected to the mains and switched on.
Pressure will start to build in the internal storage tanks which can be monitored by
watching the output pressure gauge on the front panel. This will climb to the factory set
pressure as noted in the specifications.
Once this pressure is reached, the compressors will continue to run until the internal
tank upper pressure limit is reached and has been maintained for a period of time. The
system will then stop one of the compressors to allow a drain cycle. Once the pressure
drops to a lower limit the compressor is switched on again. This will continue with the
compressor being switch off alternating to allow duty sharing and minimise compressor
wear.
Should the gas demand on the generator drop to a flow level, approximately less than 5
lpm, or if the gas demand stops then the compressors will shut off after a short period
of time. They will restart automatically when demand is resumed.
When the system has been operated for a period of 30 minutes, all the internal pipe-
work and storage tanks will have been purged with Nitrogen.
The Generator is now purged and the tubes can be connected at the rear of the unit.
