1.0 GENERAL
This manual covers the operation and calibration of the Model TS-453 Test Set for the
Airbus A380 escape slide lighting system. The Model TS-453 is designed to test for
short circuit conditions and/or electrical cross-talk in escape slide lighting circuits and
aircraft interface harnesses.
This device is a GO/NO-GO tester that does not provide parametric electrical readings.

THEORY OF OPERATION
2.1
The Model TS-453 Test Set detects short circuits and/or electrical cross-talk conditions
in A380 escape slide lighting systems and electrical interface harnesses by verifying
each of the ten different circuits against all other circuits connected via the interface.
Testing is conducted relative to nominal threshold values of 2 M
Ω
and 6.7K
Ω
depending
on particular circuit at test. Circuit selection, sequencing, and testing are controlled by a
microprocessor in the device.
2.2
After proper hook-up and activation per the operating instructions, the TS-453 conducts
a self-test to confirm readiness for test. When the self-test is complete, testing of the
connected interface harness and systems will commence automatically. The test set
cycles automatically through each of the ten circuit tests (described in Appendix A),
illuminating each of the indicator LEDs, in order, left to right, top to bottom as the circuit
test is completed. The following indications are provided:
