TB 1-1730-229-30-3

_____ d. Set load bank to off. Set AGPU AC POWER SWITCH to RESET and return to OFF.

4.5.3.4 MEP-360D AC Current Limit Test.

_____ a. Set AGPU CURRENT LIMIT SELECTOR to AH-64D (90 KVA) and the AC power switch to on.

_____ b. On the electrical load bank, set LOAD SWITCH to ON. Set the load bank to 55 KW. Hold for

5 seconds.

EGT: _______F

Check that load meter on AGPU indicates 133% load

________AC % Load

_____ c.

Set the load bank to 75 KW. After 30 seconds, the OVER CURRENT lamp will illuminate

followed by a 30-second delay before the UNDER VOLTAGE lamp illuminates and the AC

POWER lamp to go out. Record the time taken for the UNDER VOLTAGE lamp to illuminate

after the OVER CURRENT lamp illuminates.

TIME: ______ sec

_____ d. Set load bank to off. Set AGPU AC POWER SWITCH to RESET and return to OFF.

4.5.4

Battery Charger Test.

_____ a. Verify that the 50 amp 28 VDC load is connected to the slave receptacle.

_____ b. Disconnect the AGPU on-board battery.

_____ c.

Apply 50 amps load. Verify that the battery voltage gauge is in the green and the charging

amps is indicating +50. Apply load for one minute, then deactivate load and reconnect the

AGPU battery.

4.5.5

DC System Check.

4.5.5.1 Verify that the BATTERY OUTPUT is OFF.

4.5.5.2 Set DC POWER switch to ON. Verify reading on DC VOLTS meter on the DC load bank is less

than 30 VDC.

4.5.5.3 Set load bank to 100 Amps. Record reading _______Amps.

4.5.5.4 Set load bank to 350 Amps. Record reading _______Amps.

4.5.5.5 Run system at 350 DC Amps load for 30 minutes. Check that cooling fans are running on the

TRU and note if air flow is not felt from unit. Stop the load test if airflow is not felt.

Hydraulic System Test. Perform hydraulic system test as follows. Connect the 10' and 30'

hydraulic hoses and Dual Service Manifold as required.

NOTE

For all steps that follow, all controls and indications are on the AGPU

hydraulic control panel unless otherwise stated.

_____ a. Recheck connection of hydraulic hoses at hydraulic load bank to assure that hose release will

not occur when pressure is applied. Ensure the load bank FLOW CONTROL valve is closed.
