2、POWER SUPPLY UNIT REPAIR MANUAL BLOCK among the 4 voltage display LED, the +16, -16 “CAUTION” LED lights up (“NORMAL” LED of +12, +48 light up). Also check that the unit shuts down about 8 2 seconds after power is turned on but that the two +16, -16 “CAUTION” LED and the “POWER” LED remain lit up. 2

3、. Check that when power is turned on while the CN502 of AC 3/3 circuit board is removed, the 4 voltage display “NORMAL” LED light up. Also check that the unit shuts down about 8 2 seconds after power is turned on, and that only the “POWER” LED remains lit up. 3. Check that when power is turned on wh

4、ile CN209 of DC circuit board is removed, the fan “HIGH” LED lights up (Fan itself also rotates at high speed). Also check that the 4 “NORMAL” LED, and the “THERMAL” LED light up about 4 2 seconds after power is turned on. Further check that the unit shuts down about 8 2 seconds after power is turne

5、d on, but that the “THERMAL” “HIGH” and “POWER” LED remain lit up. After making the above checks, reinsert the connectors that were removed in each item to make the above checks. 21 PW5000 3-1-5 Check operation of +12 volt and +48 volt detector circuits 1. Check that about 4 2 seconds after power is

6、 turned on while the power supply units primary line (CN103 of AC 1/3 circuit board) is disconnected; among the 4 voltage display LED, the +12, +48 “CAUTION” LED lights up (“NORMAL” LED of +16, -16 light up). Also check that the unit shuts down about 8 2 seconds after power is turned on but that the

7、 two +12V, +48V “CAUTION” LED and “POWER” LED remain lit up. 2. Check that about 4 2 seconds after power is turned on while the power supply units secondary line (CN110 of AC 1/3 circuit board) is disconnected; among the 4 voltage display LED, the +12 “CAUTION” LED lights up and (+16, -16, +48 “NORM

8、AL” LED light up). Also check that the unit shuts down about 8 2 seconds after power is turned on but that the 1 “CAUTION” LED (+12) and “POWER” LED remain lit up. After making the above checks, reinsert the connectors that were removed in each item to make the above checks. 3-1-6 Check operation of

9、 FAN STOP detector circuit Clamp the fan so that it does not rotate. Then check that the “NORMAL” LED and “STOP” LED (red) light up about 4 2 seconds after power is turned on. Make this check separately for the 2 left and right fan units. After finished making the above check be sure to unclamp the
