4.9 Power Management
Incorrect power down or unplugging the HygroGen while in use may cause software
corruption
.
This may mean the HygroGen2 will not start. In this event, contact your supplier or nearest HygroGen
service centre; they will be able to provide you with a bootable USB disc that can be used to restore the
HygroGen to the factory condition. If this is not possible, then HygroGen will need to be returned for
repair, so we strongly advise that shutdown and power management procedures are carefully observed.
If there is risk of power spikes or breaks, it is recommended that an
Uninterruptable Power Supply
(UPS)
is used to provide continued power and mains filtration. This should be rated according to the
HygroGen power specifications (see Section 10) and the time required to run/shut down during power
outage.
HygroGen shut down should always be in accordance with the two procedures using the touch screen as
described in 4.10. In the event of a failure of these procedures, please observe the following:
The front panel power button functions are:
Front Panel Power button, 1 second push:
•
Switches the HygroGen on
•
Switches the HygroGen off without saving any settings. It does not allow the
HygroGen to dry the chamber or isolate the humidifier.
After pushing the switch once it will take about 15 seconds for the HygroGen to switch off.
Front panel Power button, 5 second push:
This forces the HygroGen to shut down immediately. The HygroGen does not dry, isolate the humidifier
or save any settings.
This process should only be used if all the other shut down options fail.
DO NOT switch off at the wall before the HygroGen has shut down.
DO NOT switch off at the back of the HygroGen before it has shut down.
