Message Overview:

Fault Message:

FAIRING BOTH SENSORS FAILED

Fault Code:

3000101IN

Associated CAS:

EVS HEAT FAIL
(Caution)

Reporting LRU: Enhanced Vision System Heater Controller (EVSHC)
System Description: 34-33-00
Schematic Diagram: 34-33-00 [ Global Express ]  [ G5000 ]  [ Global XRS ]
Wiring Diagram: 34-33-03 [ Global Express ]  [ G5000 ]  [ Global XRS ]

Fault Description:

Both Temperature Sensors in the Enhanced Vision System (EVS) Fairing has been detected either shorted (< 165 Ω) or opened (> 600 Ω) by the Enhanced Vision System Heater Controller (EVSHC).

Possible Causes:

  • Fairing Temperature Sensor 1
  • Fairing Temperature Sensor 2
  • Fairing (HR30)
  • Enhanced Vision System Heater Controller (EVSHC) (A315)
  • Associated Wiring

Troubleshooting Tips:

Advisory Wire/Service Bulletin: None

Forum Articles/Infoservice/Newsletter: None

Troubleshooting Recommendations:

  1. Perform wiring checks between EVSHC and the fairing as follow:
    NOTE: Nominal resistance between sensor terminals is 293 ohms ±4 ohms at 20 °C (68 °F). See Fairing Sensor Resistance vs Temperature Chart.

    From To Result
    A315P1-A HR30J1-A
    A315P1-B HR30J1-B (RTN)
    A315P1-C HR30J1-E
    A315P1-D HR30J1-D (RTN)

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.

  2. Replace fairing.

    1. If system checks are good, do close out.
    2. If fault remains, continue with next step.

  3. Replace EVSHC.
  4. Do close out.
