Channel Amp. Temp. Warn. ([xx] ° C): the temperature of the heat sink is
very high, the air flow should be checked (fan filter) or the load should
be reduced.
Channel Amp. Overtemp. ([xx] ° C): the temperature of the heat sink is too
high and the device is muted and the loudspeaker output is switched off.
After cooling down to a permitted operating temperature the device will
switch on automatically.
Channel Amp. Temp Err. ([xx] ° C): the temperature of the heat sink of the
device is too high. The device is muted and the loudspeaker output is
switched off. After cooling down to a permitted operating temperature
the device will switch on automatically.
Channel Top/Sub-Mismatch: In conjunction with the "Dual channel mode" a
TOP cabinet is connected to a SUB configured channel.
2.5.2 System Check, Load and Input Monitoring
During the calibration procedure of the System Check and Load
Monitoring function the following error messages may appear:
Device Power is off: the device is in Standby mode and a calibration is not
possible.
Channel Amp is muted: the respective channel of the device is muted and a
calibration is not possible.
Channel Current too low: the pilot signal level was increased to the
maximum, but a sufficient current has not been reached. Check
connections and wiring.
Channel Current too high: the maximum current was exceeded at minimum
pilot signal level. Check the wiring for short circuits.
Channel Cancelled (by User): the user has interrupted the calibration either
locally or remotely.
2.5.3 Error messages during operation
During operation the following error messages related to Load
Monitoring (LM) and Input Monitoring (IM) may appear:
Note: If both Load and Input Monitoring are activated and if both
detect an error, Load Monitoring obtains the highest priority and
therefore only the error messages related to Load Monitoring are
displayed.
Channel (LM) SpkrFault ([xxΩ Ω Ω Ω /xxΩ Ω Ω Ω ]): both LF and HF paths of the connected
loudspeaker have failed or the loudspeaker has been disconnected. The
display shows the value (ohms) that caused the error.
Channel (LM) SpkrFault LF ([xxΩ Ω Ω Ω ]): the LF path of the connected loudspeaker has
failed. The display shows the value (ohms) that caused the error.
Channel (LM) SpkrFault HF ([xxΩ Ω Ω Ω ]): the HF path of the connected loudspeaker
has failed. The display shows the value (ohms) that caused the error.
Channel (IM) Input Monitoring Fault: an Input Monitoring error has occurred,
e.g. the detection of an incoming pilot signal has failed. This message
applies to all operating modes of Input Monitoring.
