Word Bit Description
B09 Pre-decompression/Plastication Logical Bridge Selection
= 0 Start Plastication Profile at End of Pre-decompression Movement
= 1 Stop and Set-output at End of Pre-decompression Movement
The module checks the state of this pause bit after completing the Pre-decompression Movement to determine what
further action to take:
if:
then the module:
SET sets its outputs to PRC33 - PRC40
RESET and SYS15-B14 = 1 immediately begins the Plastication Profile
RESET and SYS15-B14 = 0 sets its outputs to zero and latches SYS13-B09
B10-B11 Open
Profile Offset Sign Selection
B12 = 0 Pack Cav Press Profile Offset is Positive
= 1 Pack Cav Press Profile Offset is Negative
B13 = 0 Pack Ram Press Profile Offset is Positive
= 1 Pack Ram Press Profile Offset is Negative
B14 = 0 Hold Cav Press Profile Offset is Positive
= 1 Hold Cav Press Profile Offset is Negative
B15 = 0 Hold Ram Press Profile Offset is Positive
= 1 Hold Ram Press Profile Offset is Negative

Pack Profile Setpoints
Word Description
HPC09 Pack Segment 1 Cavity Pressure Setpoint [04] If you select Cav Press/Time profile execution, the module controls cavity pressure
to this setpoint after starting the Pack Profile for time period specified by HPC11.
HPC10 Pack Segment 1 Ram (Screw) Pressure Setpoint [01] If you select Ram Press/Time profile execution, the module controls ram
(screw) pressure to this setpoint after starting the Pack Profile for time period specified by HPC11.
HPC11 Pack Segment 1 Time Setpoint [21] The module controls the selected process pressure to the setpoint HPC09 or HPC10 for this
time period beginning with initiation of the Pack Profile.
HPC12 Pack Segment 2 Cavity Pressure Setpoint [04] If you select Cav Press/Time profile execution, the module controls cavity pressure
to this setpoint at completion of segment 1 for time period specified by HPC14.
