If an incident is reported you can disable it, and all less serious incidents, by right clicking
the bar in System View and selecting ‘Enable/Disable Alarms’. Doing this will show a cross over
the Incident indicator and the device will no longer report any Incidents at this level or below. If
any Incidents have previously been disabled they can be enabled by using the right click
context menu and selecting ‘Enable/Disable Alarms’ again.
Any active incident will be shown on the display of the device.
A Fault state will also cause the Fault Relay to open. See
5.7.2
Fault Relay
Three connections are available via the Phoenix connector for this relay. The schematic
representation printed on the rear panel shows the ‘idle’ state of the relay (when the amplifier is
not switched on). When the amplifier is switched on, the relay will normally energise. When a
Fault incident occurs, the relay will be de-energised. This will allow either a Fault Incident or a
loss of power to be seen as a ‘Fault’.

Performance Logging
The System Engineer application allows you to inspect various performance
measurements, including various graphs of performance against time, recording events over a
period of up to three days. Since the amplifier cannot record any events whilst powered-off,
breaks in a log due to power-downs are indicated by a break symbol || in the log. The events
recorded are:
Supply Current
- How much current is being supplied to the device via the mains inlet
DC Link Voltage
– A voltage which is derived from the mains supply voltage
Thermal Capacity
– How much of the available thermal capacity has been used
Driver Current
(for each output) – The average current being delivered to the driver
Driver Impedance
(for each output) – The average impedance of the driver
Protection Limiting
(for each output) - How much the amplifier is ‘dimming’ itself in order to
protect itself from potential damage
The data in the log can be exported by right-clicking on the log to launch a context menu,
and selecting “copy log data to clipboard”. The data could then be pasted into a spreadsheet for
further analysis. Tecnare may ask you to do this is you have experienced a problem.
Alternatively, all of the operational and performance data, including the logs may be collected
together into a single file by selecting File > Save Device Diagnostics. This data can be used by
Tecnare to diagnose your amp.
