Discussions Regarding
25X1
Users of the Type II material have pointed out the
desirability of continuously recording the package V/H rate (actual)
on the SC&DM record for ease in evaluation work.
When the SC&DM system was added to the Program, Type II
was able to easily supply the required proportional AC voltage for
active or automatic V/H rate recording. However, when the system
switches to programmed V/H, only a DC voltage signal is available and
a compromise was agreed to, whereby the SC&DM would record a pre-
determined V/H setting during this period of operation. To establish
the operational V/H rate during the programmed mode, the PI must
extract this information on an elapsed time basis from the original
V/H program data. This method is time consuming and not extremely
accurate.
Should it be required that continuous V/H input be provided
to the SC&DM records, this may be accomplished by an equipment
modification. Configuration wiring changes could be made in the field
while the Programmer Module Modification must be made at the home plant.
This Modification does not effect the basic operation of
the Type II system but is a request from the users of the material output.
While our recommendations are only secondary in nature, it is suggested
that this Modification be approved.
