CONTROLLER WIRING: Safety Requirements
As shown in the wiring diagram (Figure 3a), the 1222’s keyswitch power must
go through the traction controller so that when the keyswitch is turned off both
controllers turn off. The fault output (Pin 24) should be able to shut down
the traction system in the case of a serious fault; otherwise the system may not
meet the international safety requirements listed in Table D-1.
As shown in the wiring diagram, two steer command devices and two
position feedback devices are used. The 1222 supervises and matches each
