Power supply related faults operate a relay the contacts of which are brought out to the
remote connectors. These contacts can be used to operate external indicators as desired.
Please refer to the
Power supply relay connections
pin-out 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 more than one PSU both relays will be triggered by the frame.
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 vertical PCB on the left hand side of the PSU will
flash repeatedly (on for one second and off for one second) if there is no speed fan signal
present on the connector SK 1 (the front left hand side of the PSU). This will occur
when the PSU fan assembly is removed or if the PSU fan stops. When the fan speed
signal is present the LED is unlit. The same red LED will light up continuously if levels
of the power rails (+5.75V or -6.0V) are outside operational limits.
Frame diagnostics (Indigo REMIND remote active panel)
An Indigo REMIND active control panel is able to display frame diagnostics information.
The frame diagnostics display will show the following information:
The status of the panel communications mode
Frame node
To enter this menu, press the Device key when in Statesman mode.
Status menu
Comment
Comms* = 422/TCP
Node = 01 Comms* = xxxx
Shows Comms mode
First frame node and Comms status
Note:
Comms (422/TCP) reflects the state of the RS422/TCP switch at the rear of the control
panel. This switch should be left in the 422 position. See Reading Comms mode and
status below for further help.
The first expression in the bottom line gives the Statesman rack address = hex switch
s 1.
