Electroair EIS Back-up Battery System Panel

The EIS Back-up Battery System (EBBS) Panel has been created for operation with dual electronic ignition systems (EIS) using a back-up battery. The panel is to give the pilot indication of EIS status and back-up battery status during operation of an aircraft.
The EIS Back-up Battery System Panel is designed for use with Electroair Electronic Ignition Systems (EIS), STC# SA02987CH or SA03286CH, and TCW Technologies
Integrated Back-up Battery System (IBBS), STC# SA04400NY. The panel has three LEDs, a voltmeter, and a switch. Two LEDs (green) will indicate whether or not the connected EIS is receiving power. The remaining LED (yellow) indicates if the back-up battery is supplying power to one of the EISs. The voltmeter indicates the voltage of the back-up battery system. The rocker switch enables the back-up battery to supply power in the event of main power failure.

Limitations:

Electroair Electronic Ignition Systems STC# SA02987CH or SA03286CH must be installed prior to installation of EIS Backup Battery Panel System.
An approved Back-up Battery must be installed in accordance with the TCW Technologies Installation Instructions prior to installation of the EIS Back- up Battery System Panel. See table below for list of approved batteries.

Product Details and General Information:

Back-up Power Master Switch:
The EIS Back-up Battery System Panel has one switch connection as identified in the wiring diagram: Back-up Power Master Switch. This switch is a rocker switch located on the right side of the panel.
The back-up power master switch gives the pilot the ability to turn the back- up battery system off and it must be utilized to turn the back-up battery system off when not in use. In some installations this may be the only means to shut down the connected equipment.
The switch enables back-up power from the back-up battery system to be available on the output wires from the TCW Technologies IBBS when power on the normal aircraft bus falls below 11 volts (22 volts for a 24-volt system).
If the normal aircraft power bus is above 11 volts (22 volts for 24-volt system), then the outputs are energized with normal aircraft power (if the pass thru-power connections are utilized) and the back-up battery remains off- line. This operation occurs regardless of the state (READY or OFF) of the Back-up Power Master switch. This allows for automatic pass through of power during normal operation.
Back-up Battery Voltage Monitor
The EIS Back-up Battery System Panel has a voltmeter that will indicate the voltage of the back-up battery. The voltmeter will only report voltage when the back-up switch is in the “READY” position. A fully charged TCW battery will indicate about 13-14.7 volts (26-29.5 volts for 24-volt system. The working current of the voltmeter is less than 20mA.
Back-up Battery Status Indicator
The yellow LED labeled “BATTERY IN USE” located on the EIS Back-up Battery System Panel will indicate when the back-up battery is providing power which will occur when power on the normal aircraft bus falls below 11 volts (22 volts for a 24-volt system).
EIS Status LEDs
The EIS Back-up Battery System Panel includes two green LEDs labeled EIS #1 and EIS #2. These LEDs will turn on when the EISs are receiving power and turn off when the EIS is not receiving power. The POH should be updated to state which EIS is connected to the back-up battery and which is connected to main battery power.

Installation of EA-26000 EBBS Series

1. Mounting the EIS Back-up Battery System Panel
   Determine the proper location for the panel and the most appropriate mounting method. The panel is 3.375 inches wide by 2.125 inches tall as shown in Figure

2. Suggested Cutout Dimensions are shown in Figure 3. Figures are not to scale. CAUTION: Before cutting or drilling, verify space is clear behind the instrument panel.
   CAUTION: Use extreme care as to not damage any wiring, instruments, structural, and fuel lines.
   CAUTION: Ensure electrical connectors are tight on switch connections. Ensure wires will not pull out of any electrical connections.

3. Insert EIS Back-up Battery System Panel into instrument panel and screw down using standard hardware.

4. Wiring for the components on the panel are explained in further steps 4-7. The panel components will have connection with the Electroair Electronic Ignition Systems and the TCW Technologies IBBS. Insulate any exposed electrical connections in accordance with 43.13-1B Change 1 section 11-159.

5. Back-up Power Master Switch
   The Back-up Power Master Switch is the rocker switch located on right side of the EIS Back-up Battery System Panel. Connect one terminal of the rocker switch on the panel to white/black wire (Pin 1) from the TCW Technologies IBBS Wire Harness. Connect to the other terminal of the rocker switch to ground.

6. Back-up Battery Voltage Monitor
   Locate the wires from the voltmeter on the panel. Connect the red/green wire (Pin 2) from the back-up battery harness to the red wire of the voltmeter. Connect the black wire of the voltmeter to ground. Connect the white wire of the voltmeter in parallel to the output pin connected to the EIS controller and low voltage LED.

7. Back-up Battery Status/ Low Voltage Indicator
   Find the yellow LED labeled “BATTERY IN USE” located on the EIS Back-up Battery System Panel. Connect the black wire of the yellow LED to the purple wire (Pin 3) of the back-up battery wire harness. Connect the red wire of the yellow LED in parallel to the output pin connected to the EIS controller.

8. EIS Status LEDs
   The EIS Back-up Battery System Panel includes two green LEDs labeled EIS #1 and EIS #2. These LEDs will turn on when the EISs are receiving power and turn off when the EIS is not receiving power. The black wires of both LEDs should be connected to ground. The red wires should separately connect to the B+ wire at the EIS On/Off switches. The POH should be updated to state which EIS is connected to the back-up battery and which is connected to main battery power.

9. Function Check
   a. Turn ON the aircraft main power.
   b. Turn ON both EISs.
   c. Verify both EIS (green) LEDs turn on.
   d. Turn the rocker switch to the “READY” position.
   e. Verify voltage of back-up battery turns on and “BATTERY IN USE” (yellow) LED remains off.
   f. Turn main power OFF.
   g. Verify the yellow LED turns on and one green LED turns off.
   h. Turn the rocker switch to “OFF” position.
   i. Verify all LEDs are off and voltmeter is off.
   j. If verification passes, then return to service. If any verification fails, reverify and correct all connections and repeat Function Check. If the aircraft fails a second time, contact the factory for support. (248-674-3433 or sales@electroair.net)
