error resume
The backup amplifier fault has been recovered
x
ESU8-x comm. fail
ESU8-x error
communication lost
The system has detected a fault in the “x” EV PROS8Z in
the chain
Check all connections to the slave
unit and check that the uniti s
powered
ESU8-x comm. ok
ESU8-xOK
comm. error resume
The communication error in the slave unit chain has been
recovered.
x
MSU5 int. failure
MSU5 internal fail
Flash error
The master unit EV PROM5Z has a fault in its internal
memory
Call for servicing.
x
ESU8-x amp. error
ESU8-x error
spare amplifier fail
The system detected a fault to the spare amplifier
installed in the “x” ESU08 slave in the chain
Check che spare amplifier and its
connections.
ESU8-x amp. ok
ESU8-x spare amp. OK
error resume
The backup amplifier fault has been recovered
x
ESU8-x A.B. error
ESU8-x error
audio bus unplugged
The connection cable to the “x” slave in the chain is
faulty
Check the cables from an to the “x” slave
module in the chain
ESU8-x A.B. ok
ESU8-x audio bus OK
error resume
The cable connection fault has been recovered
x
Comm fail **name**
LMM1 communication error
Position: MSU5 slot-x
or
Position: ESU8-y slot-x
Zone name: xxxxx
Communication error between the master unit and the
line module installed in nr. “x” slot of the master unit or
communication error between the line module installed
in nr “x” slot of the nr “y” slave unit in the chain.
Check that the line module is inserted
correctly inside the indicated master or
slave unit. Check the connection cables of
the master-slave chain. Reboot the system. If the
fault does not recover, call for servicing.
Comm OK **name**
LMM1 comm. error resume
Position: MSU5 slot-x
or
Position: ESU8-y slot-x
Zone name: xxxxx
The communication error indicated above has been
recovered
x
Msg. fail **name**
LMM1 int. message error
Position: MSU5 slot-x
or
Position: ESU8-y slot-x
Zone name: xxxxx
Message storage error on the line module installed in nr.
“x” slot of the master unit or on the line module
installed in nr “x” slot of the nr “y” slave unit in the
chain.
Reboot the system to automatically reload
the message. If the fault does not recover,
call for servicing.
Msg. OK **name**
LMM1 mess. error resume
Position: MSU5 slot-x
or
Position: ESU8-y slot-x
Zone name: xxxxx
The storage error indicated above has been recovered
x
Line fail **name**
LMM1 line to ground error
LMM1 line open error
LMM1 line underload error
LMM1 line overload error
LMM1 line overcharge error
LMM1 line short error
Position: MSU5 slot-x
or
Position: ESU8-y slot-x
Zone name: xxxxx
Indicates a fault in the loudspeaker line
-Ground leackage.
-Line open
-Load loss
-Load increase
-Overload
-Line shorted
The system indicated on which module the fault has
occurred and zone name
Check the impedance of the loudspeaker line.
Check the cables.
Line OK **name**
LMM1 line to ground OK
LMM1 line open OK
LMM1 line underload OK
LMM1 line overload OK
LMM1 line overcharge OK
LMM1 line short OK
Position: MSU5 slot-x
or
Position: ESU8-y slot-x
Zone name: xxxxx
The indicated fault (see above) has been recovered
x
Cal. fail **name**
LMM1 calibration error
Position: MSU5 slot-x
or
Position: ESU8-y slot-x
Zone name: xxxxx
The calibration line on the indicaed module and zone
name has failed. The system was not able to set the
amplifier gain for 100V output voltage.
Check
the
impedance
of
the
loudspeaker line and check that the
power amplifier is able to drive the
load. Increase or decrease slightly the amplifier
volume on its potentiometer and perform
calibration again.
Cal. OK **name**
LMM1 calibration OK
Position: MSU5 slot-x
or
Position: ESU8-y slot-x
Zone name: xxxxx
The calibration process of the indicated line was
successful and all parameters for line and amplifier
monitoring were acquired.
x
