Automatic Shutdown Bleeping interpretation during starting procedure
If the system shuts down before finishing the start up procedure then please refer to the following
bleeping interpretation:
If the system stops during the starting:
Bleeps Interpretation Actions
1.
Low fuel cell open voltage protection i.e. the average cell voltage is <0.7V.
2.
High ambient temperature protection, the ambient temperature around the system is >45˚C.
3.
Low external power voltage protection i.e. external power is <12V.
Automatic Shutdown Bleeping interpretation during running procedure
If the system shuts down during operation within the product parameters then please refer to the
following bleeping interpretation:
Bleeps Interpretation Action
1.
High current protection i.e. current is too high
- For H-100 - H-300 is > 12A set by the controller.
- For H-500 - H-1000 is > 30A set by the controller.
2.
High temperature fuel cell protection i.e. fuel cell is running >65˚C.
3.
Low voltage fuel cell protection i.e. the average voltage per cell is <0.5V
Note: If one of the above situations occurs, the stack will disconnect the load and make an alarm.
Reduce the demand of the load on the fuel cell. The system will re-connect the load every 10
seconds. If the situation causes the initial disconnection is the same, the system will again disconnect
the load.
Diagnosis
"Fuel cell internal short circuit"
"Controller internal short circuit"
"Controller reading too low voltage"
"Controller not operational"
"Supply valve not opening"
"Purge valve is not opening"
"Blower(s) not operational"
"LCD not operational"
"High current protection"
"High temperature fuel cell protection"
"Low voltage fuel cell protection"
"High ambient temperature protection"
"Low external power voltage protection"
"Temperature sensor resistance different"
Note: If the diagnosis refers to a "Yes" from the above list, shut down the system immediately
to avoid potential further damage to the fuel cell and contact support@horizonfuelcell.com.
If the system shuts down by itself check the following details
1.
Make sure you have connected all wires according to the Sytem Setup Diagram.
2.
Check the connection of the external power that the voltage is providing 12V -14V.
3.
Confirm that the input hydrogen pressure is 0.45-0.55Bar.
4.
Make sure the load is below 100W. Overload can trigger the stack protection function to
avoid the damage to the stack.
5.
Check whether the fuel cell temperature is below 65
