Each M1 port (I/O interface) is assigned two -color LEDs which indicate the configuration or
operating states.
Standard I/O Port
Display Request / Signal
LED1 (PIN 4)
off Output = 0 Input = 0
yellow Output = 1 Input = 1
red I
Output
> I
max
Input: SC*
LED2 (PIN 2)
off Output = 0 Input = 0
yellow Output = 1 Input = 1
red I
Output
> I
max
Input: SC*
*SC= Short circuit detection on Pin 1. In this case both LEDs are red.
