Address Setting
Ethernet / LAN
AX3800 can be remotely monitored by external software to check condition of the amplifiers as well as notification when-
ever a duty amplifier failed.
RS485 data is provided which can be directly connected to local PC via RS485-232 converter or through network via
Amperes iPX5500 Communication Box.
Application with iPX5500 can be from single or multiple locations. When there are several AX3800 connected, it is
important to set the address correctly with each AX3800 assigned to a unique number.
API can be obtained for 3rd party software integration.
Fault Detection
AX3800 may work a little different from other auto standby amplifier fault changeover. It sends Pilot Tones of 20 kHz to
amplifiers at intervals and shift from one channel to another to reduce loading strain. A slight delay in detection shall
occur but is more beneficial in the long run, prolonging the life span of amplifiers.
Whenever Pilot Tone is sent out, a PT Active LED at front panel shall lit.
Pilot Tones
AX3800 detects availability of returning Pilot Tones at every channel. Missing Pilot Tone shall be interpreted as faulty
amplifier at that particular channel.
A minimum level of 50V signal must be presence to avoid unnecessary fault diagnosis. Thereby, it is recommended that
all amplifiers’ output levels be set to minimum 50%.
Fault Detection
Any faulty channel shall be indicated by top row of LEDs ( AMP.NORMAL / FAULT ) to red. A fault shall be accompanied
by AMP FAULT ALERT LED and also switchable buzzer switch. Concurrently, a data string shall be transmitted ( RS485
) along with activation of a dry contact.
As only one channel is allowed for changeover, which is to prevent overloading, only one LED shall lit at the second row
of LEDs. ( AMP. CHANGEOVER ).
