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

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.
