Otis · DSD 412 DC Elevator Drive
This fault is declared if the number entered for Rated Field Current (parameter #50) is outside the acceptable range for the Field Interface board (A3) current rating. This rating is determined by the field sense resistor selected by SW1 on the Field Interface PCB. A DSD power down is required.
Click steps to track your progress.
Enter a value for parameter #50 (Rated Field Current) that is within the acceptable current rating range of the Field Interface board (A3).
Verify the field sense resistor selected by SW1 on the Field Interface PCB is correct for the application.
Perform a DSD power down after adjusting the parameter.
