Fire Bird V ATMEGA2560 Hardware Manual
Battery charging procedure:
1. Make sure that battery is inserted in battery connector, and robot is turned off.
2. Connect AC adapter in the mains. Connect the 6pin 2510 relimate battery charging
connector to the main board in the battery charge socket as shown in figure 3.13.
3. Now turn on the AC adapter. After a small delay, green LED will turn on along with the
one long beep two short beeps followed by delay of 1 second. This tone will be sounded
only once. This audio tone confirms that robot is entered in the battery charging mode. If
you do not here this tone, then repeat steps 1, 2 and 3.
4. When battery is fully charged, green LED will turn off and buzzer gives 2 short beeps
followed by 1 second delay continuously. Depending on the version sometimes robot will
also give 1 long beep followed by delay.
5. If there is any fault then charger will give different buzzer beeps to indicate nature of
fault. Following section describes the interpretation of the battery state with beeping
buzzer.
Battery status indication based on the buzzer beeps and red and green LEDs:
Important:
Battery status indicator Red LED blinks in sync with buzzer. So in the following
text only buzzer's status is mentioned.
1. Battery Low:
(only applicable when robot is running on battery power)
One long beep followed by 2 short beeps repeated after delay of 1 second continuously.
2. Battery entered in the charging mode:
When AC adapter is connected to the battery charging connector and powered up and if robot
enters in battery charging mode, it gives One long beep followed by 2 short beeps only once.
During battery charging mode green LED remains ON. It blinks for 3-4 seconds after 3-4
minutes.
3. Battery is fully charged:
When battery is fully charged, green LED will turn off and buzzer gives 2 short beeps followed
by 1 second delay. Depending on the version, sometimes robot will also give 1 long beep
followed by delay.
4. Charge termination due to over current:
During charging process, if charge current exceeds safe threshold value then robot terminates
charging and buzzer gives 1 short beep repeated after delay of 1 second continuously.
5. Charge termination due to time out:
If battery is not fully charged in 6 hours, then robot stops battery charging and buzzer gives 3
short beeps repeated after delay of 1 second. If battery is unused for long time then it is possible
that robot terminates battery charging due to timeout. In such case, discharge the battery fully
and again start charging. You should repeat this 3 to 4 times till issue gets resolved. If still the
issue is not resolved then batteries have reached end of its usable life but you can still use battery
with the robot. However the run time of the charged battery will be reduced significantly.
