3D.2.8 AEC Board (Universal AEC Board With Short AEC Time Compensation) Cont
In order to clearly show the adjustment pots on the lower (AEC) board, the upper board which
contains the AEC and PMT interface connectors and the high voltage supply is shown shifted
from its actual position.
AEC board input/output assignment:
•
Ch 1 = J1 - Table Radiographic Bucky.
•
Ch 2 = J2 - Vertical Wall Bucky.
•
Ch 3 = J3 - Spot Film Device.
•
Ch 4 = J4 - Aux. (Extra Bucky, Digital Acquisition, etc.).
•
J7 = High voltage output for the PMT (if used)
The following potentiometers are used for AEC gain adjustment:
•
R1 is used for channel 1 gain adjustment.
•
R2 is used for channel 2 gain adjustment.
•
R3 is used for channel 3 gain adjustment.
•
R4 is used for channel 4 gain adjustment.
The following potentiometers are used for short AEC exposure time compensation:
•
R91 is used for channel 1 short exposure time compensation.
•
R92 is used for channel 2 short exposure time compensation.
•
R93 is used for channel 3 short exposure time compensation.
•
R94 is used for channel 4 short exposure time compensation.
Refer to tables 3D-8 and 3D-9 for the connector pinouts. Refer to the end of subsection 3D.2.7 for the
procedure for adjusting R10, R19, and R24.
