Figure 25 Battery Pack Installation
3)
Verify the gasket is in place and in good condition.
4)
Lay the battery pack on the work surface with the cells facing up.
5)
Align the ELT with the battery pack, holding it slightly above the pack with one hand.
6)
Connect the ELT flex cable receptacle to the plug on the battery pack circuit board using the other hand,
taking care not to put a twist in the flex cable.
NOTE: The receptacle should “click” into place when properly mated to the plug.
7)
Reset the ELT by toggling the ELT local control switch to “ON” and back to “ARM” after 1-2 seconds, if
the ELT activates.
NOTE: This step may be necessary because the ELT will occasionally activate when power is
connected to it in Step 6.
8)
Fit the battery pack into place on the ELT, making sure the gasket is positioned correctly.
9)
Turn the battery pack bottom face up to facilitate installing the screws, while securely holding the ELT
and battery pack together.
10)
Install the eight battery pack retaining screws and tighten until the ELT is snug against the gasket.
11)
Torque the screws to 10-12 lb-in (113-136 N•cm).
12)
Perform an ELT self-test as follows:
a)
Set the ELT local control switch in the “ON” position. The LED will begin flashing every 3-4
seconds.
b)
Return the switch to the “ARM” position after 1-2 seconds. If the ELT is working properly, the
LED will stay on for approximately 1 second. The ELT may flash the following expected error
codes, which should be ignored.
1.
3-flash and 4-flash errors, which are generated because the ELT is not installed and
connected to an antenna, etc.
