alarm operation
Upon a manual reset of the front panel switch the PDU measures the current flow in each of the DC output channels. If the current falls between an upper (480mA) and lower (50mA) limit the channel is enabled and the channel is permanently powered. However, an output will be disabled if an open circuit (no TMA connected) or short circuit (installation fault) is detected upon the manual reset. Once a DC output channel is enabled the normal operating current is saved and if a significant change in operating current (±30mA) is detected on any channel of the PDU an alarm state is raised. For full details of the LED indications see the table below.
TMA current (mA) Status LNA Indicator LED
ON RESET    
<10mA Channel switched off Off
>530mA Channel switched off Off
>700mA Channel switched off Red (alarm)
AFTER RESET    
< learned current minus 30mA LNA failure low current, channel remains on Orange (alarm)
Learned current ±30mA LNA ok and operational Green
>learned current plus 30mA LNA failure high current, channel remains on Orange/Red (alarm)
>630mA LNA failure high current, channel switched off Red (alarm)
