Hi..
One of my customer is using DAC161S997 for their Industrial product where they are controlling the motor speed using 4 to 20mA input.
They are using 24V as Loop power supply for 4 to 20mA output & they also use 3.3V as external power & this 3.3V is not taken from the loop supply.
In above case, when 24V is not present they are not able to get the fault status on EERB pin and also through status register.
Also want to know if 24V connection is not present (consider wire break condition), will it show any loop error status either through ERRB or Error status register?
Need help, what could be the issue?
