3. Working mode information
The KANNAD 406 AF / AF-H / AF (6D) have 4 different modes:
• Off.
• Self-test (temporary mode).
• Armed (standby mode to enable automatic activation by the shock sensor
or by the remote control panel).
• On (transmission).
Transmission is effective if the beacon is activated (either manually on the ELT
control panel, remotely by the "ON" switch on the remote control panel or
automatically by the shock sensor) =.
A. Off
The ELT is off when the switch is in position "OFF".
No part of the ELT is energized.
This mode must
only
be selected when the ELT is removed from the aircraft or
parked for a long period or for maintenance.
B. Self-Test
The self-test mode is a temporary mode (max duration 5 sec) in which the ELT
checks the main characteristics of the transmitter (Battery voltage,
Programming...) and enables digital communication with a programming and
test equipment.
This mode is selected:
• when switching from "OFF" to "ARM";
• when switching to "RESET / TEST" on the Remote Control Panel
(provided that the switch of the ELT is in the "ARM" position);
• when switching to "ON" prior to transmission.
The buzzer operates during the self-test procedure.
After about 3 seconds, the test result is displayed on the visual indicator as
follows:
• One long flash indicates valid test.
• A series of short flashes indicates false test result.
The number of flashes indicates the type of failure:
• 3 + 1 = LOW BATTERY VOLTAGE.
• 3 + 2 = LOW TRANSMISSION POWER.
• 3 + 3 = FAULTY VCO LOCKING (FAULTY FREQUENCY).
• 3 + 4 = NO IDENTIFICATION PROGRAMMED.
It is recommended to test the ELT regularly in order to detect any possible
failure (
Refer to A. Periodicity, page 301
).The number of self-tests carried out
is recorded. This information is available when the ELT is connected to a
