FAULT STATUS INDICATORS

The LED patterns below indicate the following fault conditions:
LED status
All LEDs are green
During power up all LEDs stay red
for an extended time
During power up or normal
operation, one or more LEDs are
flashing green, with the remaining
LEDs solid red
During power up or normal
operation, one or more LEDs are
flashing green, with the remaining
LEDs NOT solid red
During power up or normal
operation, one or more LEDs are
flashing red, with the remaining
LEDs solid red
During power up or normal
operation, one or more LEDs are
flashing red, with the remaining
LEDs NOT solid red
During power up or normal
operation, one or more LEDs are
flashing amber
During power up or normal
operation, one LED is flashing
amber, with the remaining LEDs
solid red
During power up or normal
operation, all the LEDs are flashing
amber
During normal operation, all the
LEDs are solid red
During power up or normal
operation, one or more LEDs are
flashing amber, with the remaining
LEDs flashing green
During power up or normal
operation, one or more LEDs are
flashing amber, with the remaining
LEDs flashing red
Description
This is the normal operating state of the
amplifier.
The amplifier is waiting for the DC offset fault
lines to clear. A DC offset fault can occur if an
excessive DC voltage is present at the output of
the pre-amp feeding the P7. Normal operation
resumes if the lines clear in 20 seconds.
The DC fault cannot be cleared.The channels
with the flashing green LEDs represent the
amplifier modules that have a DC offset fault.
Alternatlively, a DC offset fault has reoccurred
on the same channel within 12 seconds of a
previous DC offset fault clearance.
The amplifier is attempting to clear a DC offset
fault on a channel with the flashing green LED.
A short circuit fault cannot be cleared.The
flashing red LEDs represent the amplifier
modules with a short circuit fault. Alternatlively,
a short circuit fault has reoccurred on the same
channel within 12 seconds of a previous short
circuit fault clearance.
The amplifier is attempting to clear a short
circuit fault on a channel with the flashing red
LED.
The amplifier is attempting to clear an over
temperature fault on a channel with the flashing
amber LED.
An over temperature fault has reoccurred
on the same channel within 12 seconds of a
previous over temperature fault clearance.The
flashing amber LEDs represent the amplifier
modules with an over temperature fault.
The amplifier is attempting to clear an over
temperature fault on more than one channel, or
the power transformers have overheated.
An over temperature fault has reoccurred
on one or more channels, or the power
transformers have overheated within 12
seconds of a previous over temperature fault
clearance.
A DC offset fault occurred on one or more
channels while attempting to clear a multiple
over temperature fault.
A short circuit fault occurred on one or more
channels while attempting to clear a multiple
over temperature fault.

Amplifier action
None
To verify excessive DC offset voltage, remove
the interconnect leads (with the P7 switchd
off) and turn on the P7.The fault should have
cleared.
The amplifier shuts down.The power switch
must be cycled to reset the amplifier (cycling
the trigger does NOT reset the amplifier).
The amplifer mutes the channel with the fault
and its paired channel.The amplifier stays in
this state for up to two seconds or until the
fault clears (whichever is sooner).
The amplifier shuts down.The power switch
must be cycled to reset the amplifier (cycling
the trigger resets the amplifier).
The amplifer mutes the channel with the fault
and its paired channel.The amplifier stays in
this state for up to half-a-second or until the
fault clears (whichever is sooner).
The amplifer mutes the channel with the fault
and its paired channel and the fan is set to
maximum speed.The amplifier stays in this
state until the channel has cooled.
The amplifier shuts down.The power switch
must be cycled to reset the amplifier (cycling
the trigger resets the amplifier).
The amplifer mutes all channels and the fan is
set to maximum speed.The amplifier stays in
this state until all channels have cooled, or the
transformer has cooled.
The amplifier shuts down.The power switch
must be cycled to reset the amplifier (cycling
the trigger resets the amplifier).
The amplifier shuts down.The power switch
must be cycled to reset the amplifier (cycling
the trigger does NOT reset the amplifier).
The amplifier shuts down.The power switch
must be cycled to reset the amplifier (cycling
the trigger resets the amplifier).
