GE - Transportation’s entry-level predictor combines the basic predictive capability of an HXP-3 processor with the easy adjustment sequence of a PMD-3 phase motion detector to deliver enhanced train approach and warning capabilities at crossings. Users can switch to the predictor function simply by selecting the constant warning option on the menu and may choose bi-directional or unidirectional selection, lumped impedance adjustment and warning time selection from 23 to 99 seconds.
