Operation Manual – ITW GSE 6400 Tier 4
d) Power Delivery
After the engine has started and the display has changed to the output status default screen, insert the
aircraft cable into the aircraft. Make sure the cable is inserted until you feel a natural resistance. The
plug may be equipped with a 90% insertion switch (split “C” pin). In this case, the unit will not function if
the plug is not fully inserted. Press the output ON/OFF button. If the unit is already at rated speed, the
contactor will immediately close. If at idle speed the engine will ramp up to rated speed, the generator
will set output voltage and the contactor will close. The green LED will turn ON next to the active output.
In addition, current power status information will appear on the output status default screen.
WARNING
All output ON/OFF buttons are active regardless of the displayed screen.
1) Early in the power delivery run it is recommended that the operator check output voltage and
current in each of the three phases. Use ▼ ▲ pushbuttons to view voltage. If the load is changing,
observe the display until load conditions stabilize.
2) A condition of over-voltage, under-voltage or overload in the output circuit will automatically open
the load contactor and display a fault code to signal the operator which of the above faults caused
the protective monitor system to operate. After the fault has been corrected, press the output
pushbutton to reset the system. Proceed with power delivery by pressing the same switch.
WARNING
NEVER disconnect the output cable while power is being delivered. Output
contactor’s must be open prior to removal of the cable from the aircraft.
CAUTION
The generator set must be shut down so the failed power delivery problems can be
diagnosed. Only personnel who are trained or qualified on this type of equipment
should work on this GPU.
e) Failed Power Delivery
If the contactor indicator light goes out and EF fault is shown on the display, this indicates that the
aircraft plug interlock circuit is no longer receiving 28.5 VDC from the aircraft power connector. Correct
the condition and press the output pushbutton to reset the fault. Press the button again to close the
output contactor and provide 28.5 VDC to the aircraft/load bank.
1) If the aircraft cable does not have the Split-C wire, set the 28V Interlock to Bypassed through the
Setup icon menu using the following steps:
2) Press and hold
●
for approximately 5 seconds. (If the ICON screen doesn’t appear and
“DISABLED” appears in the display screen, contact the Maintenance department for access to the
SETUP menu to unlock.)
3) Use the navigation keys (
◄▼▲►
) to highlight the setup icon. Press
●
to select.
4) Set EF interlock to bypass.
5) Press
●
to accept the change.
6) Use the
◄
navigation key to go back to the Icon screen. The display will return to the default
screen after a period of inactivity.
