AMPLIFIER SHUTDOWN
Amplifier shuts down due to an alarm or as a result of a hardware or software command.
A software shutdown is performed at either the front panel or by selecting the MUTE ON
function key sending the appropriate code via the RS-485 serial interface, see
Section 4.3.2
page 29. The amplifier can be restarted in a similar manner provided a hardware shutdown is not
in effect. The amplifier can also be restarted by switching power off & on the PA. Note that in a
redundant system, if the MUTE command is issued by the operator to the ON-LINE unit, the
system will automatically switch the other unit as ON-LINE and the muted unit as STANDBY.
When the amplifier resumes operation, the attenuation level will return to its previous setting
after about 2 minutes of stable operation. Note however that the amplifier will not restart if a
FAULT condition is detected.
