This is a draft manual, technical specifications are subject to change
Enter a number between 60 and 100 to set the production rate to a desired percentage (60%-100%).
Then click on the button "Create Command". The production can be adapted in 1% steps.
Attention: Please note that if a lower value is set (for example 50), the production rate
will be set at the smallest possible value (60%). Accordingly, higher numbers than 100
will result in 100% production rate.

RAMP UP
The ramp up time of the device depends on the electrolyte temperature (the ramp up is slower at low
ambient temperatures). Typically, the device will start with a hydration period of 60 seconds, and
then ramp up to the nominal production rate with the following values:
Warm-up time (time taken for the electrolyte to heat up to 55 °C): The electrolyser can reach a
heating ratio of 1 °C/min. If starting the device with an electrolyte temperature of e.g. 25 °C it will
take about 30 min to be fully operational and perform at its maximum efficiency at 55°C.
Ramp up time (time to reach nominal production rate): Usually, the 500 NL/hr production rate is
reached in about
⅔
of the total warm-up time (the warmup time is 30 min, so if starting at 25 °C,
it will need 20 min to reach max production rate).
Build pressure time: The heat up and the hydrogen production start immediately. With standard
set-points, the pressure is completely built in
⅙
of the total warm up time (if starting at 25 °C, the
warm-up time is 30 min, so it will need 5 min to build pressure).
During ramp up, the device performs periodical vent to guarantee high purity H
2
on the outlet, as well
as to release condensed water from the produced H
2
.

RAMP DOWN
Like the Ramp Up, the Ramp Down slowly switches off the stack and the other components and moves
the device into a safe state. The device should always be ramped down via the start/stop button or via
the app/cloud to preserve the components. Switching it off via the breaker, the Dry-Con or switching
off the power supply should be performed in emergency cases only.
