Fault
:
LED illuminates in red when amplifiers have reported a general fault (over-temperature,
over-current, or other) and have shut down or failed. Recycling the power may clear some
types of faults. An over-temperature fault will clear after allowing the system to cool down.
5.4.3 AC Input Connector
The AC Power Input connector accepts 90 to 260 VAC from a 50 or 60 Hz supply. The AC is
converted into 24VDC and fed to the LRAD’s amplifiers to power the unit.
The connector provided is of the designation:
Amphenol DL series DL3102A18-10P
This connector provides four #12 pin contacts with a pre-earth/first mate last
break protective ground circuit. The following figure shows the pinout for this
connector:
Pin A: AC Primary Line (BROWN WIRE)
Pin B: Not Connected
Pin C: Neutral Line (BLUE WIRE)
Pin D: Earth Ground (GREEN/YELLOW WIRE)
5.4.4 Resettable Breaker
In the event of an internal electrical failure or short circuit, the resettable breaker will trip,
disconnecting power to the unit for safety.
5.4.5 MP3 Control Unit Indicator LEDs
Power: LED illuminates in green when Volume/Power control is on and amplifiers have been
powered up.
Clipping: LED illuminates in yellow when input signal is too high. Excessive input signal level
will cause distortion on the output and may damage the amplifier if applied continuously.
When using the microphone, this means that the operator is shouting too loudly into the
microphone and should adjust their voice level or the position of the microphone with respect
to their mouth. When using an external audio device such as a CD player, this means that the
output volume on the CD player is set too high and should be turned down until the Clipping
LED no longer illuminates. The Clipping LED will not illuminate when using the LRAD’s Control
Unit unless there is a malfunction in the Control Unit or the LRAD’s preamp.
Fault: LED illuminates in red when amplifiers have reported a general fault (over- temperature,
over-current, or other) and have shut down or failed. Recycling the power may clear some
types of faults. An over-temperature fault will clear after allowing the system to cool down.
