Section 1: General
This Airplane Flight Manual Supplement contains the necessary information required for
the operation of the Electroair Electronic Ignition System (EIS) Back-up Battery System
(EBBS) Panel, Part # EA-26000-12 and EA-26000-24.
The EBBS Panel, presented in Figure 1, is designed for use with dual EIS, STC#
SA02987CH or SA03286CH, and TCW Technologies Integrated Back-up Battery System
(IBBS), STC# SA04400NY. Each of these STCs incorporate a separate AFMS for the
prerequisite systems. Specifically, 4-cylinder EIS (SA02897CH) document number AFMS
EIS-41000, 6-cylinder EIS (SA03286CH) document number AFMS EIS-61000, and TCW
Integrated Back-up Battery System (SA04400NY) document number 725.0005.

A. FUNCTIONAL OVERVIEW
The EBBS panel has three Light Emitting Diodes (LEDs), a voltmeter, and a rocker switch.
Illumination of the EIS #1 or #2 LEDs (green) indicates the respective EIS is receiving
power. Illumination of the BATTERY IN USE (amber) LED indicates the back-up battery
is supplying power to the connected EIS. The voltmeter indicates the voltage of the back-
up battery system. The rocker switch enables the back-up battery to activate when the
aircraft primary electrical system drops below the acceptable range. See Table 1 for label
description.
