Failsafe Dual Redundant Supply
Wheatstone failsafe power supply systems use two separate rackmount power supplies
for each piece of powered equipment. Though either is capable of running a full load on
its own, in failsafe operation both units run in tandem: if one fails, the other takes over,
assuring uninterrupted operation.
In order for failsafe systems to perform as designed, always have BOTH rackmount
supplies powered up and connected to their associated equipment.
Energizing
Assuming the Lightning console mainframe is properly placed, and its SPS-130
power supply (or supplies) correctly rackmounted and connected to the console, you
may now energize the rackmount power supply by plugging it into the AC mains. The
“POWER” LED on the power supply front panel should light up to indicate the presence
of the voltage. The console’s switches will assume factory default settings.
NOTE: To de-energize the control surface, unplug the rackmount power supply’s
AC cord from the AC mains. Never de-energize the console by disconnecting the cable
that connects the console and power supply together.
Once you have veried proper power-up, unplug the rackmount power supply to
de-energize the console. You may now proceed to wire up audio and control connections.
