Indicating battery errors (DPSI battery switch)
Red LED
•
Steadily lit if charging state of corresponding battery is low
for more than 10 minutes. There is low voltage (=>urgently
charge battery).
•
Quick blinking, if the battery voltage drops below 5.0 volts.
Fast blinking therefore indicates e.g. loose contacts or a
totally emptied battery. The error indication is active until
power off.
Yellow LED
•
Steadily lit if the battery is discharged down to about 60-70%
(no low voltage yet). The error indication is active until power
off.
Indicating receiver errors (DPSI receiver switch)
Green LED
•
As long as the corresponding receiver provides a valid servo
signal to the failsafe input of the DPSI, the LED is steadily lit.
Green therefore stands for: receiver ok. If an erroneous or a
defined failsafe signal or no signal at all is recognized at the
failsafe input, the LED is turned off.
•
If the receiving quality drops and the receiver shows several
malfunctions, the green LED flickers. The LED therefore is
an indicator for decreasing receiving quality (=> range test).
Blue LED
•
The blue LED always indicates which receiver is active and
which receiver provides the connected servos connected to
the DPSI system control signals (left LED = RX1 active, right
LED = RX2 active).
