On the display of the EM4TII+ a flag signalizes the current supply frequency (DC, 16.7 Hz, 50 Hz or 60
Hz) in the case of a detected traction system.
Furthermore, in the billing load profile and in the logbook of EM4TII+ any change of the traction
system is stored with the seconds-accurate timestamp.
This includes any change (in multi-system vehicles), and the achievement and leaving of any traction
system according to EN 50163.
4.2.8 Error register (F.F)
