Operation
Front Panel
On the left of the front panel is a toggle switch and an OLED display with four buttons.
The switch is programmed to run sequence up and sequence down macros making it work in a similar way to an
on/off switch. However, it should be noted that the macros can be changed through external software to make the
toggle switch operate completely differently, or not at all.
The OLED display gives access to all the measurements available in the PDU subject to the model specified.
Operation of the front panel buttons should be self-explanatory, following the icons/text on the display next to each
button.
On the right of the front panel are the fuse(s) and LED(s) associated with the Inlet(s). The fuse(s) are only for the
internal PSU components, they are not in the distribution chain. Appropriate protection should be installed in the
supply to the PDU.
eyePower PDU LEDs and Alarms
eyePower PDU are available with a single inlet or dual inlet changeover versions.
eyePower
changeover
PDU have two inlets, which are labelled ‘A’ & ‘B’. Failure of ‘A’ will cause changeover to ‘B’.
On return of ‘A’, when both supplies have been stable for ten seconds and the two supplies are synchronous for
one mains zero crossing, an eyePower PDU will change back to ‘A’ automatically. Note this delay can be changed
using eyePower Limited’s Windows software via the serial port.
When the audible alarm is enabled, the unit will beep, and output LEDs will flash to amber to attract attention to
an alarm condition. The first press of any OLED button will silence the alarm but continue to show the cause of
alarm on the front panel inlet LEDs. A second press of the button will cancel the visible indication if the warning is
historic, for example supply failed. The visible warning will remain if the problem remains, e.g. red channel LED to
show fuse failure.
When the
audible alarm is not enabled, such silent alarms follow the description above after the first button press.
Possible LED warnings include faults that have never been seen in installations and only produced under R&D
conditions. Warnings
are included for completeness, in service units have proven extremely reliable.
