Operation
The ARI-500 has an Auto Reset for the amplifier's load fault (O/L). When the
amplifier goes into load fault mode, the ARI-500 will wait 5 seconds and then
switch the amplifier's Power off and back to on for operation. The ARI-500
will reset the amplifier overload up to 3 times in a 5-minute period. If the
amplifier load faults more than 3 times in a 5 minute period the amplifier's
power will have to be manually switch off for reset. JMP3 set to 2 and 3 will
turn the Auto Reset off. Fig C
Switching the ALS-500M's Power On/Off will still be the same as with out the
ARI-500M. Refer to the ALS-500M operation manual for remote on/off
operation. If the Remote ALS-500RC is going to be used refer to Operating
ALS-500RC with the ARI-500.
The amplifier's power switch will need to be in the off position for the Auto
Load Fault reset to work.
The amplifier will now be keyed by the ARI-500 for transmit and receive. The
relay jack on back of the amplifier will not be used.
The Amplifier's Frequency Select Switch should be in the Remote Position.
22.5 to 30 MHz (10/12 Meter) Operation
The ARI-500 has a jumper labeled JMP1. The JMP1 is for operation on
frequencies between 22.5 and 30 MHz (AUX). The factory default is in the off
position (2 to 3). The off position will prevent the amplifier from operating
when the transceiver is in the 10/12 Meter band. Move JMP1 to ON, if the
amplifier has the 10 Meter kit installed. See Fig C.
