    Good afternoon.

    We have polar mohr machine as 90.
    Due to problems on the 24V supply line, the sensors and some boards in the SPS basket failed ...
    The sensors have been replaced with new, detected damage on PI, HD-R, DNF boards have been eliminated by replacing the damaged components with new ones.

    Now we have such a picture: the machine turns on, the shutter moves, the light protection works, the input cards in the SPS basket register the operation of sensors and buttons, but there are no output signals on the output cards!? Simulation buttons trigger the corresponding mechanism, but the control buttons do not work. There is no backlight buttons will not turn on hydraulic unit of the Elevator ...

    On the Board there is a CP1 clock pulse and a chip AM9513APC produces various clock pulses - i.e. it sabermetrician processor and they work ...

    How, what and where it is possible to reliably diagnose the health\health boards ...
    how to look for the problem!?

    Hi sir
    Good Day:
    Your paper cutter is 92 ED , not 90
    well please test the following boards as emergency situation look for the schematic diagrams :
    1)Power module AC: FUSE f3 for +24Vdc+8Vdc +Fuse F4 for +25Vdc +F5+F5 for 15Vca abnd 30Vca
    2)Power module DC: Fuse F7: +24vDC +f8 :230vAC +F10: 32vDC
    3)Power modulo KAP: led 8 FUSE 7= +24vDC +lED 9 FUSE FUSE 10 +45vdc +lED v10 fuse f3= +24vdc +led V11 f3 =+8Vdc +led V12 fuse f4 =+25Vdc.

    Good afternoon.
    Thanks for the reply.
    The power is all tested and works both the lower power supply and the F200.
    Fuses are intact.
    According to the results of our searches, there is a feeling that the CP1 Board either does not receive any resolution signal for the output boards, or receives some prohibiting signal (blocking).
    Since some life on the Board CP1 oscilloscope is registered ...
    .
    if the power is turned on without the CP1 Board, then the output Board 3 includes all the outputs, which is also logical, because the data exchange on the rear bus in the SPS basket goes in the reverse state - that is, both the address bus and data bus are pulled to + 12V and this potential should be planted by the already controlled outputs of the CP1 Board, thus forming a task ...
    .
    That still can be\need to do for search fault ...

    Dear Sir:
    Hi, can understan the situation.
    However i will strong call the attention to test Again Carefully, the tolerances of the power supply board 95 (PS95):
    1) in the Board 95 (PS95)
    +24 Vd.c. Tolerance 23.7 to 24.3 Vd.c.
    +12 Vd.c. Tolerance 11.4 to 12.6 Vd.c.
    +5 Vd.c. Tolerance 5.08 to 5.12 Vd.c.
    If they are out , you had found the problem and fix it.
    Let me know.

    voltage on the lower power supply:
    25V -> 28
    24V -> 24.1
    8V -> 11.2
    45V -> 49.3
    24V -> 27.2

    voltage on F200:
    +5V -> 5
    +12V -> 11.7
    +24V -> 23.5

    45V -> 49.3
    24V -> 27.2
    This voltage are out of tolerance, You must repair and try to set up the tap of primary of Transforme, and see if there are a good situation.
    Otherwise replace or repair.
    Let me know
