output to load will be temporarily disconnected.
LED will blink. Check and ensure sufficient
Hydrogen supply and correct delivery pressure.
"Error: Low H2 Supply"
◉
Hydrogen supply pressure is too low. Check and ensure
sufficient Hydrogen supply and correct delivery pressure.
Restart the system.
"High H2 Supply Pressure"
●
Hydrogen supply pressure is too high and the supply valve
will be temporarily shut off. LED will blink at 80%.
Reduce the delivery pressure.
"Error: High H2 Supply Pressure"
◉
Hydrogen supply pressure is too high. Check and ensure
sufficient Hydrogen supply and correct delivery pressure.
Restart the system.
