Procedure to reset the fault
If the FCM-801 has a fault it will disconnect the internal DC-DC converter and stop
providing power. To reset a fault follow the procedure below:

Installation specific
Fault state
If the parameters of the FCM-801 leave the normal operational range the controller
will adjust the operation of the fuel cell to try to compensate; but if this is not
possible then a fault is triggered. When a fault has been triggered the controller will
latch. To clear the fault, the controller needs to be reset by cycling the Enable / Reset
signal. Any faults that are trigger before start will prevent the unit starting. For reset
instructions see Section 9 – Faults.
Optimising the Fuel Consumption of FCM-801
The fuel cell uses the hydrogen to produce electrical current (plus water and heat).
The cell efficiency can be improved with the following steps:
· Products will be most efficient if used often. The FCM should be run at more
than 80% power for 30 minutes, at least once a quarter.
· Products will be most efficient, and have longer life, if operated at between
50% and 100% power.
· Products will be most efficient if operated between 10°C – 20°C.
