LED Status Indicators
The P MX 5262, P MX 5264and P MX 5268 has LED indicators on the edge of the card
that serve as alarm and status indication for the module. Function is described below.
Status LED 1
Alarm LED 2
** Note
The Alarm LED will occasionally flash yellow during normal operation (black then a quad
yellow flash). This is indicating the module is updating the stored settings in flash ram
and is normal. No error condition exists and this function does not effect normal module
operation.
Using the “Locate” function from the module GUI in the control system can also cause the
Alarm LED to flash yellow (black then a triple yellow flash) this is used as a tool to
physically locate a module in a system and does not indicate a fault condition.
