CONTROL LOGIC SPECIFICATION
| Undervoltage trip |
Contactor control logic will initiate a trip within 25ms
if 28 VDC supply drops below 20 Vdc while load current is equal to or above 460 Amp +/- 6%.
The contactor will remain in the open state until a reset command sequence is provided.
|
| Over current trip |
Contactor control logic will initiate a trip if load current exceeds the I2t trip curve.
The contactor will remain in the open state until a reset command sequence is provided. |
| Reset command |
The contactor clears, from the latched state, by removing 28 Vdc power (open circuit)
for a period greater than or equal to 250 ms. The contactor resets by removing CMD input
(open circuit) for a period greater than or equal to 5 ms. |
| Undervoltage lockout |
The control logic shall command open and the ELCU shall de-energize within 50 ms of the
28 Vdc power supply dropping to less than 9.5 Vdc. The control logic shall maintain all
functions when the 28 Vdc power supply is between 10 to 18 Vdc.
