DPSI RV Family Operating Instructions Version 2.1

Error type 2 has the second highest priority and remains active until the
DPSI is turned off. When using LiPo cells, a condition is reached where
the batteries can be irreparably destroyed if not turned off immediately
and if the batteries are not immediately charged.
3. Low voltage in Battery 1:
⎯ ⎯ ⎯ ⎯⎯⎯⎯⎯⎯⎯⎯
Error signal: 3 x 0.1 second beeps, each with a 0.1
second pause, then a 1 second beep
If the voltage of Battery 1 drops below a certain value, this buzzer code
is emitted. The capacity of the battery is generally still sufficient for one
flight before it needs to be recharged. Nevertheless, the battery should
be recharged immediately after the error code sounds. It is always a
prerequisite that the correct type of battery has been programmed (5,
6, 7 NiCad/NiMH cells or LiPo). This error code is repeated in 7-second
intervals. Once the error has been qualified, it remains active until the
DPSI is turned off.
4. Low voltage in Battery 2:
⎯ ⎯ ⎯ ⎯⎯⎯⎯⎯ ⎯⎯⎯⎯⎯
Error signal: 3 x 0.1 second beep with a 0.1 second
pause each time, then 2 x 0.65 second beep with a 0.1
second pause
If the voltage of Battery 2 drops below a certain value, this buzzer code
is emitted. The capacity of the battery is generally still sufficient for one
flight before it needs to be recharged. Nevertheless, the battery should
be recharged immediately after the error code sounds. It is always a
prerequisite that the correct type of battery has been programmed (5,
6, 7 NiCad/NiMH cells or LiPo). This error code is repeated in 7-second
intervals. Once the error has been qualified, it remains active until the
DPSI is turned off.
If both Battery 1 and Battery 2 exhibit low voltage, both error codes will
be emitted alternately. Error types 2 and 3 have lower priority than
error code 1 (short circuit). Therefore, in case of a short circuit, error
code emissions 2 or 3 will be interrupted.
