6.4.
Nitrogen production
When the generator has completed the preparation phase (par. 6.3.) and the
message
GENERATOR READY is displayed, nitrogen production can be star-
ted up as follows:
Press the key START/STOP.
The production cycle is started up and the following message is displayed:
PRODUCTION
e
NOTE: if production is started up after turning on the generator as described in
par. 6.3., the generator runs a number of washing cycles for the molecular sie-
ves before starting up actual production of nitrogen. During this phase, lasting
approx. 15 minutes, the message
PURGE
is displayed. At the end of this phase,
production will be started up automatically.
6.5.
Stop the generator
At any time during production the generator can be stopped by pressing the key
START/STOP.
Depending on the phase activated, the generator starts to depressurise imme-
diately, or awaits conclusion of the production cycle before activating depressu-
risation.
During depressurisation, which usually lasts from 30 to 60 seconds, the following
message is displayed:
WAIT…
DEPRESSURISATION IN PROGRESS
e
NOTE: if a production block alarm is active, the START/STOP key is disabled
At the end of depressurisation, the following message is displayed:
GENERATOR READY
There are then two alternatives:
1. Switch off the generator by pressing the POWER key (see par. 6.6.);
2. resume the gas production by pressing the key START-STOP (see par. 6.4.)

Correct shutdown
Correct shutdown of the generator starts from the condition of GENERATOR
READY
. par. 6.5. describes how to reach this condition.
