Incident Reporting

In the System Engineer application, a coloured indicator appears on a Device Bar in the System View
which displays the Incident state of the device. The Incident state may be one of three states:
Red: Fault (The device is faulty in some way and requires attention)
•
Yellow: Check (The device may not be performing to its full and should be checked)
•
Green: OK (The device is performing well and requires no attention)
•
Holding your mouse over the Incident indicator for a few seconds will show the current incident level
and name.
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.
A Fault state will also cause the Fault Relay to open. See
A Check state will also cause the Check Relay to open. See

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. Your dealer may ask you to do this is you have experienced a problem.
