6 Operating the FCPM
6.1 Startup using the Start button
Note When the battery is connected, the output is live!
1. Check at least one HMI is connected.
2. Check regulator interface is connected.
3. Check fuel lines are connected to both SPMs.
4. Check that there is sufficient fuel available.
5. Connect battery.
Note Output is now live
6. Press the start button until audible fan noise is heard (max 5 seconds).
7. Fuel cell startup process will begin.
8. Check error codes to ensure the system has started correctly.
9. When the LED is green fuel cell power is available (approx. 5 seconds after
starting system).
6.2 Startup using digital signal
For remote operation via a digital signal, use the process as outlined in section 6.1
Startup using the Start button. However, step 6 must be changed to:
1. Pull up (3.3V) start pins Start 1 and Start 2 on the HMI analogue/digital
connector for 4 seconds.
6.3 Shutdown using the Start button
The procedure to shut down the FCPM:
1. Press button for 4 seconds.
2. Wait until LED stops flashing orange before moving to next step
(removing battery early will corrupt the micro SD card).
3. Disconnect batteries.
4. Isolate hydrogen cylinder.
6.4 Shutdown using digital signal
For remote operation with a digital signal, use the process as outlined in section 6.3
Shutdown using the button. However, step 1 must be changed to:
1. Pull up (3.3V) start pins Start 1 and Start 2 on the HMI Analogue/Digital connector
for 4 seconds.
6.5 Monitoring of data output
See logging and data connections (section 7)
For operational safety during flight it is essential to monitor remaining
hydrogen fuel pressure, battery voltage, run state and error codes.
Not doing so could lead to unexpected loss of power.
