High Voltage Shutdown (HVSD)
This feature provides protection to the load from over voltage conditions originating from the rectifiers.
It operates by shutting down the offending rectifier module when a high output voltage condition occurs.
Indication is through the red Alarm (Module Fail) LED. Modules will restart automatically; however, if more
than three over voltage conditions occur in one minute, the module will latch off and remain shut down
until it is reset.
Battery Eliminator Operation
Rectifier modules maintain all specifications (except where indicated) with or without a battery attached
in parallel to the output; however, if a battery or another module supplying DC voltage in parallel is not
present, there will be no monitoring or control activity if there is an AC power failure or input fuse failure.
3.2. Overview of the CXCi HP
The CXC HP in-shelf controllers have a small organic LED (OLED) display. This display shows 30
characters total (five lines high, six characters wide) and the controller has three navigation buttons and
one reset button.
The in-shelf display has three main operating modes: dashboard, menu and screen saver. After 20
minutes with no activity, the in-shelf controller goes into screen saver mode and the display shuts off.
From screen saver mode, press any of the three navigation buttons to re-activate the screen and enter
dashboard mode.

Display
In dashboard mode, the in-shelf display shows the key operating parameters of a system. For example,
output voltage and load current. If more than one system is defined, you can cycle between systems
using the
Forward
and
Back
buttons. With multiple systems, you can specify a default system, which is
then displayed first.
Refer to the software manual for set up.
