CAUTION LAMP

Pic. 175
13.6.2.2) Warning lights
See Pic. 175.
The TCU is furnished with output terminals for an external red warning lamp
and an orange caution lamp.
Location of the lamps depends on type of aircraft and is limited by the length
of the wiring harness. Standard location is on the instrument panel.
When switching on the voltage supply of the TCU the function of the two
lamps is automatically checked. For approx. 1 to 2 seconds both lamps light
up and then extinguish. If this should not happen check the following:
➪ Inspection for physical damage
➪ Verify connection of cable harness
➪ Check warning lamps for function
◆ NOTE: The two warning lamps are not in the supply volume of
engine.
■ ATTENTION: Exchange any part with physical damage or if not operating
correctly, without delay.
