No external comms being received.
External comms present
If a PSU is not fitted, the corresponding LED will not illuminate. If the front panel is
open, the Front Fan LED will also be unlit.
The Comms LED indicates external communication with the frame. On a passive panel
this will mean communication from the frame or an active control panel. On an active
panel this will be communication with Statesman via an RS422 link or via Ethernet.
The Comms LED flashes slowly at medium intensity if communication has been
established. It will flash at higher intensity when the communication channel is active.
When a fault is cleared, the corresponding LED (if appropriate) will return to normal. The
Indigo REMIND active front panel can also be used to interrogate the status of the front
panel and installed PSUs by pressing Enter when those devices are listed in Device view.
Statesman users will be able to remotely monitor frame temperature and fan speed.
