Fault

Cause

Action

No power from the
module

No command to start

Verify that the module is in Enable and Run modes

Hydrogen leak

See 11.1

Check for fuel leak

Incorrect hydrogen pressure

See 11.2

Fuel check procedure

No power provided

See 11.3

Electrical system check procedure

Fuel cell is over temperature

See 11.4

Stack temperature

11.1

Check for fuel leak

Remove electrical load from fuel cell

Set fuel cell to ‘Off’ and ‘Disabled’

Remove sources of ignition

Verify hydrogen source

pressure is within specification

(application specific)

Contact IE Product

Support Team

Can the leak source be

identified

Isolate hydrogen source,

contact IE Product

Support Team urgently

Have a gas trained person

repair or replace damaged

component(s)

Conduct pressure decay test on

external hydrogen supply system

Restart fuel cell system

Is fault repeated?

Isolate hydrogen source, contact IE

Product Support Team

Return to operation,

report event to IE

Product Support Team

yes

pressure stable

pressure

dropping
