New Monitor Groups Will Keep Water Out Of EMS Panel{7490}

Usage:

All Machines So Equipped

Description of Change: New monitor groups are now used in the instrument panel groups on all machines equipped with electronic monitoring systems (EMS). The new panels use a different housing design that will keep water out and have improved circuitry inside. Also, new films (decals) are available in several different languages for the different applications. The decals explain the function of the lights in the EMS panel.

The design of the former monitor groups has permitted water to get inside the EMS panel in some applications.

Adaptable As: The new 3T9100 and 3T9200 Monitor Groups are direct replacements for the former 3T1321 and 3T3136 Monitor Groups respectively. The part number of the new films, their applications, and languages are shown in the chart.
