Hint:
At delivery, low voltage recognition of the DPSI RV Mini systems is programmed
for 2-cell LiPo batteries. If other battery types are to be used, the corresponding
battery type must be programmed in first place (see chapter 9.10.)!
Output voltages for receiver and servos are both set to 5.9 volts at delivery.
7. Safety Features of DPSI RV Systems
Because of the results of FMEA and an elaborate design DPSI RV
Mini is especially safe:
Short-circuits at contacts of the male multi point connector where the
switch actuators cable is connected to, do not damage the DPSI RV
Mini. Therefore even not a defective (squeezed) switch actuator cable.
Shorts on servo pulse lines, no matter whether to ground or positive,
do not any damage, too. All other servos of that channel, where there
is a short-circuit pending, remain fully functional. Even reverse polarity
of a servo does not harm to the DPSI RV Mini.
Mistakenly shorted servo cables usually burn up or melt without
damaging the DPSI RV Mini. The heat sink naturally gets very hot at
events like this!
Both batteries are totally decoupled and also the electronically
switches (inclusive peripheral electronics) are doubled. There are no
dual diodes (two diodes in one housing) built in. Therefore, no
malfunctioning part can cause total fail of the system. This circuitry has
been proven outstandingly several thousand times.
A DPSI RV Mini must not be disconnected from its batteries during
long breaks (e.g. in winter time) because the self discharge of the
batteries is much higher than the quiescent current consumption which
practically is not measurable.
