LEDs

All LEDs light up during power-up for
diagnostsics purposes.
 : LED solid on
 : LED off
 : LED ashing
*1: Snn: n = number off LED of affected input, LEDs ashing alternatingly
*2: Snn: n = number off LED of affected input, LEDs ashing synchronously
*3: STATEn: n = 1 = Instantaneous
n = 2 = Delay
*4: LEDs: All LEDs except POWER
