If the outlet pressure set-point is reached and maintained for a period of 5 minutes, the generator closes the
outlet valves and continues to cycle for a further 5 minutes whilst continuously monitoring outlet pressure,
after which, if pressure is still maintained high, the generator shuts down into economy mode.
If at any point during this time, if the outlet pressure drops below the set-point, normal cycling operation
resumes.
When the generator is shut down remotely, the shut down procedure will commence. The current cycle will
be completed, then both exhaust valves will open for 2 minutes to exhaust the CMS bed. After which the
exhausts will be closed, in effect sealing the generator ready for start up.
