Hi all,
My sm74/2, machine runs OK, the delivery and feeder pile works alright but the dampers motors does not run,when I check the console in INIT test is giving me an error on SAK-FFEF, SEK-FFCF, HAK2 m1-OOOO,HAK2 M2-OOOO,HAK2 M3-OOOO and I DYN test HAK-FFDD. The LTKs are ok
 
Hi sir:

This are the possible faulty in his machine Heidelberg SM 74-2

1)Brushless drive-IC (BLA-IC) on HAK defective.

2)Tacho-IC on HAK defective.

3)Failsafe timer has run down and was not retriggered.

4)EPROM on HAK defective.

5)RAM on HAK defective.

6)Motor code could not be determined.

7)Motor or power part on HAK defective.

8)Code of power part could not be determined.

However test the LTKs LED diode following: Nomal operation , the diode is goes OUT ,when the motor start rotating.and light up when the motor is Stand by. o.k??
By other sides if they are Light up when in case
Malfunctions :
1)No enabling HAK or Overcurrent or FUse blown F2, OR F1 or Both.
