Leds On S500-Fbp Modules - ABB AC500 Introduction Manual

LEDs on S500-FBP modules

All S500 modules have LEDs for the display of operating statuses and error messages. They indicate:
LED Meaning
Input digital input
analog input
Output digital output

UP process
voltage 24 V
DC via
terminal
PWR 24 V DC via
FBP
S-ERR Sum Error

*)
*) All of the LEDs CH-ERR1 to CH-ERR4 (as far as they exist) light up together
For the meaning of the different LEDs and their behaviour when the system is running, please refer to
the S500 System Data of the S500 User's manual for further information.

Color LED = ON
yellow input = ON
yellow brightness depends on the value of the
analog signal
yellow output = ON
yellow brightness depends on the value of the
analog signal

red serious error, data
exchange is
stopped, depends
