P/N 0112478

A second identical set of three is on the platform-
control box.

The EMS ENVELOPE lights (1) give the operator
information about where the platform is located
relative to the platform’s safe working envelope.
(See the “SPECIFICATIONS” chapter for the
TB100J safe working envelope.) The EMS
STATUS (2) and EMS WARNING lights (3) tell
the operator whether or not the envelope
management system is operating correctly.

NOTE: EMS lights on the platform-control
box have the same names as those on the
instrument panel even though they are not
labeled on the platform-control box.

In addition to EMS lights there are EMS audio
alarms.

Two are above the instrument panel.

Two are on the bottom of the platform-control
box. The audio alarms emit various sounds to
alert the operator to unsafe conditions. The audio
alarms and EMS lights work together to give
valuable safety information. The table below
summarizes that information.

NOTE: When a TB100J engine first starts,
the EMS self-test will briefly sound all EMS
audio alarms and briefly turn all six EMS
lights on to check that they work. After the
brief EMS self-test, conditions in the table
below prevail.
