Locating Beeper Operating Instructions Version 1.0
Page 8 of 20
For 2.4GHz sets or when using PCM modulation, i.e. if servo signals of
the receiver assume a failsafe value caused by a missing transmitter
signal, then the Locating Beeper recognizes a defined servo signal
(failsafe < - 100%), which also leads to an alarm.
As an additional feature, the Locating Beeper monitors the receiver
supply. As soon as it drops below 4.8 volts, a continuous alarm is
output by buzzer codes (low voltage code). This alarm indicates to
the pilot an under supplied receiver.
Triggering buzzer codes and their meaning:
There are several acoustically error codes with different meanings
which the Locating Beeper can output.
3.1. Low Voltage Code
As soon as the receiver voltage drops below 4.8 volts an alarm sounds
after a qualification time of 2 seconds, i.e. a continuously repeating
alarm signal. The signal corresponds to the low voltage code of the
EMCOTEC DPSI family devices, 3 times short and one time long,
repeated every 7 seconds.
Output of the buzzer signal continues until turning the equipment off,
this means the indication is not reversible. This error points to an
empty battery or to high voltage drops of the receiver which in the
worst case can lead to a reset of the receiver. If low voltage is
detected, a corresponding signal occurs.
If there is no servo signal detected by the Locating Beeper after the set
is turned on for 5 seconds, it is assumed that it should not monitor a
servo signal but rather only the receiver supply.
This is a special case! There is only an error indication for low voltage
(supply < 4.8 volts) and servo signal evaluation is not carried out.
