Test Passed / Failed
–Once fully depressurized the generator switches to standby and the result of the test is displayed.
NOTE:
Always perform a self-test whenever the pressure circuit has been disturbed e.g. changing the desiccant cartridge.

4.4 Hard Reset
If a critical error occurs, an error lock menu will be displayed and the generator will need to be hard reset. If an overpressure, H2 or
O2 vent blocked error occurs, the generator will need to be hard reset once the problem has been resolved. This will also be the
case if the same error is reset 3 times consecutively.
Before a hard reset is performed the initial fault must be rectified; refer to “Error Messages” on page 21 for guidance. When the
faults are rectified, switch the generator off at the mains switch.
Press and hold
. At the same time reapply the power to the generator. When the generator has powered up press
again. The generator will reset all errors then continue with the normal start up procedure.
4.5 Stopping the equipment and depressurizing
Ensure that the generator is fully depressurized prior to shipment or servicing.
1
Ensure that the application instrumentation no longer requires hydrogen.
2
Switch the generator off at the mains power switch and disconnect it from the electrical supply.
3
Slowly disconnect the Hydrogen outlet connection pipe from the back of the generator allowing the system to depressurize. Once
depressurized, close the hydrogen outlet valve port.
Hydrogen gas will escape under pressure when the piping is disconnected.
4
The generator is now shut down.
5
If the generator is to be transported drain the water from the generator as described in section 6. Refit the hydrogen outlet port
plug and the two transit plugs to the excess H2 vent and the water bottle vent.
