TASK 31-60-00-740-002-A
Electronic Instrument System (EIS) Input Test

WARNING: MAKE SURE THAT ALL THE CIRCUITS IN MAINTENANCE ARE ISOLATED BEFORE YOU SUPPLY ELECTRICAL POWER TO THE AIRCRAFT. UNWANTED ELECTRICAL POWER CAN BE DANGEROUS.

WARNING: STOP THE FUEL TANKER 60 m (196.85 ft) FROM THE AIRCRAFT NOSE WHILE THE WEATHER RADAR OPERATES. DO NOT OPERATE THE FUEL TANKER/PUMP UNIT UNTIL YOU STOP THE OPERATION OF THE WEATHER RADAR.

WARNING: MAKE SURE THAT:

NO PERSON IS IN THE AREA MADE BY AN ARC OF 135° ON EACH SIDE OF THE AIRCRAFT CENTERLINE. -THERE IS A MINIMUM SAFETY DISTANCE OF 5 METERS (16.4FT) BETWEEN THE AIRCRAFT AND ANY OBSTACLE IN THE AREA MADE BY AN ARC OF 90° ON EACH SIDE OF THE AIRCRAFT CENTERLINE.

4. Procedure
Subtask 31-60-00-740-050-B ** ON A/C NOT FOR ALL

A. EIS Input Test

NOTE: This test is for DMC1. For DMC2 use the indications between parentheses.
For DMC3, there is a special procedure is used.

ACTION	RESULT
1.On the MCDU, on the INST menu page:
Push the line key adjacent to the EIS1 (2) indication.	Make sure that: * The CAPT (F/O) PFD and ND and the upper (lower) ECAM DU operate in the maintenance mode. * On the MCDU, the EIS DMC1 (EIS DMC2) page comes into view.
Push the line key adjacent to the TEST indication.	On the MCDU, the EIS DMC1 TEST (EIS DMC2 TEST) page comes into view.
Push the line key adjacent to the I/P TEST indication.	The I/P TEST IN PROGRESS indication comes into view; then the I/P TEST RESULTS and the NO BUS FAULT (or TCAS/ADF warning message(s) if TCAS/ADF is(are) not installed) indications come into view.
Push the line key adjacent to the RETURN indication as necessary to have the INST page again.	The CAPT (F/O) PFD and ND and the upper (lower) ECAM DU go back to the normal mode.
2.On switching panel 8VU, set the EIS DMC selector switch from NORM to CAPT/3.
3.On the MCDU: Push the line key adjacent to the EIS3 indication.	Make sure that: * The CAPT PFD and ND and the upper ECAM DU operate in the maintenance mode (MAINTENANCE MODE comes into view on these 3 display units) * On the MCDU, the EIS DMC3 page comes into view.
Push the line key adjacent to the TEST indication.	On the MCDU, the EIS DMC3 TEST page comes into view.
Push the line key adjacent to the I/P TEST indication.	The I/P TEST IN PROGRESS indication comes into view; then the I/P TEST RESULTS and the NO BUS FAULT (or TCAS/ADF warning message(s) if TCAS/ADF is(are) not installed) indications come into view.
Push the line key adjacent to the RETURN indication until the CFDS MENU page comes into view.	The CAPT PFD and ND and the upper ECAM DU go back to the normal mode.
4.On switching panel 8VU, set the EIS DMC selector switch to NORM.

5. Close-up
Subtask 31-60-00-860-060-A ** ON A/C NOT FOR ALL

A. Put the aircraft back to its initial configuration.
(1) Do the EIS stop procedure (Ref. AMM TASK 31-60-00-860-002).
(2) On maintenance panel 50VU, press the ENG/FADEC GND PWR 1 & 2 pushbutton switches (the ON legend goes off).
(3) Do the ADIRS stop procedure (Ref. AMM TASK 34-10-00-860-005).
(4) On the radar control unit, set the control switches back to their initial position.
(5) On the ATC control unit, set the control switches back to their initial position.
(6) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
(7) Make sure that the work area is clean and clear of tools and other items.
