iPS10 User Guide 9
Notes on Operating the iPS10
The iPS10 is intended as a backup power supply for iLive system
components. At the time of release of this user guide it can be used
with any of the 4 surfaces (iLive-80, iLive-112, iLive-144 and iLive-
176) and the iDR0 DSP MiniRack. These components can operate
using their internal mains power units only. Connecting the iPS10 in
addition to the internal supply provides dual supply redundancy. The
component can be operated with either or both supplies switched
on. It continues to operate without interruption if either supply is
switched off or loses power.
The iPS10 features a universal mains voltage input that can accept
any AC mains voltage between 100 and 240V AC. We recommend
that it is run on the same power distribution that feeds the iLive unit
being connected to. For protection against temporary loss of mains
power an external UPS (uninterruptible power supply) could be used.
Make sure the iPS10 and the iLive unit being connected to are both
turned off before plugging or unplugging the mains and DC POWER
cables.
Blue LED indicators on the CPU module at the rear of the iLive
surface light to indicate that the power supplies are switched on and
working correctly. There is one for the internal surface supply and
one for the backup supply. The iPS10 sends power good/fail status
signals to the iLive via its 10way DC cable.
The iPS10 front panel blue POWER ON indicator lights at full
brightness to indicate normal operation. If a voltage rail fault is
detected then it reduces to half brightness. If this happens, switch
the unit off and contact your Allen & Heath service agent.
The iPS10 has an internal fan to assist cooling and ventilation. The
fan runs at constant speed. Thermal protection is provided to safely
shut down the power rails if the unit reaches 85 degrees C internally.
If this happens check that the fan is running, the ventilation slots are
not blocked and there is adequate airflow around the unit. Switch the
unit off and allow it to cool. When it has cooled sufficiently it
automatically resets and resumes operation.
The CAT5 cable provided with the unit is used to send the
temperature status to the iLive. The current temperature measured
within the iPS10 is displayed on the iLive Surface TouchScreen
Utility/Diagnostics/Temperature Display page. The minimum and
maximum temperatures reached are also displayed. These values
can be reset.
