6Chapter 2 – Introduction
2Introduction
During the operation of automated guided vehicles (AGV) there often is a demand to
let the vehicles play notification sounds at certain positions throughout the track. For
this purpose the audio player HG G- 31500 was developed. Various interfaces make
system integration easy. An audio amplifier for direct connection of loudspeakers is
already integrated.
The audio player does not have internal speakers. External speakers and USB stor-
age medium are not included in the scope of delivery.
2.1 Connection Overview
The following picture shows the usual connection options for the audio player.
Figure 1 Connection options
2.2 Interfaces
The audio player is characterized in particular by its large number of inputs, which
can be used to control the selection and playback of audio files. The supply voltage
range of 10 – 30 V was also designed so that the player can be easily integrated into
a vehicle.
NOTICE
Damage to USB storage media and/or loudspeakers
USB storage media and loudspeakers are available in versions for different
operating temperature ranges. The audio player can cover a wide operating
temperature range. If it is operated in a temperature range for which the USB
storage medium and speakers are not specified, they may be damaged.
The USB storage medium and speakers must be selected so that they match
the temperature range in which the audio player is operated.

3.7 Audio Amplifier
The integrated audio amplifier has a nominal power of 2 x 10 watts into 4 ohms. The
peak power is up to 2 x 25 watts, which should be taken into account when selecting
the speakers.
The maximum achievable power values depend on the level of the supply voltage
as well as the level of the audio files. The mentioned power values are reached from
the nominal voltage of 24 volts and a file level of 95 dB.
3.8 Selection Mono/Stereo
The audio player supports the playback of stereo files. If only one speaker is to be
connected to the device, it is recommended to select the Mono mode. For this pur-
pose, either mono audio files can simply be used, or mono operation is forced by ap-
plying ground potential to input Mode of connector ST 2 (connector ST 2: connect
pin 11 with pin 12, s. section 3.5.2 on page 9).
3.9 Potentiometer
The potentiometer is used to set the maximum volume. This value then corresponds
to 100 %. The adjustable volume is thus in the range from 0 % (silence) to 100 %
(potentiometer value).
For the adjustment, an audio file with a volume of 100 % must be played back. This
can be achieved as follows:
