If a PSU is not fitted, the corresponding LED will not illuminate unless the incorrect number of
PSUs are selected when it will flash red.
VisionWeb users will be able to remotely monitor frame temperature and fan speed.
Power supply related faults operate a relay, the contacts of which are brought out to the Remote
2 and Remote 4 connectors. These contacts can be used to operate external indicators as
desired.
Please refer to the Connector pinout section for more details.
PSU relays
Each PSU contains a relay, the contacts of which are brought out to the remote connectors.
This relay is under frame control and will change state whenever a frame fault is present.
Note:
If the frame is fitted with two PSUs the frame will control both relays
simultaneously. These contacts can be used to operate external indicators as
desired.
Note:
In certain circumstances there may be a delay of several seconds between the
first relay and any other relay's state changing.
Note:
The red LED built into the front of the PSU will flash repeatedly (on for one
second and off for one second). The same red LED will light up continuously if
levels of the power rails (+5.75V or -6.0V) are outside operational limits.
