No power from
the FCM-801
Check that the hydrogen
source has pressure
available
Check the hydrogen
supply is fully open
between the source and
the fuel cell
Check that the regulator
pressure is >500mbar.g
Check that the regulator
pressure is <700mBar
Switch on the FCM-801
Check that the fuel
pressure is maintained
during a purge
Has the tank been
purged with hydrogen?
Must be >99.9%
hydrogen
Rerun the fuel cell and
monitor for a repeat
of the fault, if it recurs
contact IE Product

Increase pressure to
600mbar ±100mbar.g
Investigate why hydrogen
regulator is dropping
during purge, contact IE
Product Support Team
Does the fuel supply quality meet the fuel standard?
Does restarting the FCM-801 clear the over pressure?
Ensure that the stored
gas is at a concentration
of >99.9% hydrogen
Provide detail of the
hydrogen quality being
used to IE Product
Support Team for review
