R **ON A/C 001-049, 051-099, 101-149, 151-199, 201-299, 401-499,
A. Do the Operational Test of the HI LVL Lights (Ref. AMM TASK 28-46-00-710-001).
NOTE : You can get more Trouble-shooting data from the CFDS(FUEL):
____
- Input Parameters Page 3 (Ref. P. Block 301), used with the Fuel Level Sensors Operating (Changeover) Values (Ref. P. Block 301)
- FLSCU Trouble-shooting Data (Ref. P. Block 301).
With the HIGH LVL TEST switch in the central (released) position
the lamp state, off or on, must agree with the bit indicator 0 or
1 respectively, in the Input Parameters Page 3.
NOTE : OPTIONAL TESTING:
____ Where a PSD A320-2 Fuel Level Sensing Test Set is available measurements can be taken before a decision is made to go into or close up a fuel tank. The Test Set enables the tank mounted components and tank wiring to be tested from the tank wall connectors.
**ON A/C 301-399,
A. Do the Operational Test of the HI LVL Lights (Ref. AMM TASK 28-46-00-710-001).
