Description
•
+5V logic power and software indication
•
Normally slow blink (1 blink/sec)
•
Off in self-test failure or SLC address = 0 (bootloader)
•
Steady on memory Flashing and POR (+5V check)
RESET active.
•
Slow blink (1 blink/sec) if SLC address = 0 (bootloader)
•
Blinks once then pause in CPS communication failure
•
Fast blink (5 blinks/sec) in self-test failure or programming
•
Steady in any other trouble, POR and memory Flashing
Steady when external trouble bus signal received (trouble bus shorted)
SLC incoming data
SLC outgoing data
485 outgoing data
485 incoming data
+24V at Main output
•
Steady if in current-limit
•
Fast blink (5 blinks/sec) in hardware failure
•
Steady on memory Flashing, or RAM self-test failure
•
Medium blink (3 blinks/sec) on application code CRC self-test failure
•
Steady if in current-limit
