PPC
Profile Pressure Alarm Setpoint
Word Description
PLC57 Profile High Pressure Alarm Setpoint [01] The module compares real-time ram (screw) pressure against this entry when executing
the Plastication Profile. The module sets alarm status bit SYS06-B07 when ram (screw) pressure equals or exceeds this entry
during the Plastication Profile. A zero entry inhibits SYS06-B07.

B02-B07 RFU
B08 Plastication/Post-decompression Logical Bridge Selection End of Plastication Profile
= 0 Start Post-decompression Movement at End of Plastication Profile
= 1 Stop and Set-output at End of Plastication Profile
Module checks the state of this pause bit at completion of Plastication Profile to determine what further action to take:
if:
then the module:
SET sets its outputs to PLC33–36
RESET, SYS15-B15 = 1, immediately begins the Post-decompression Movement
and PSC05 > 00000
RESET, SYS15-B15 = 1,
sets its outputs to PSC33–36
and PRC05 = 00000
RESET and SYS15-B12 = 0
sets its outputs to zero and latches SYS13-B10
B09-B11 RFU
Profile Offset Sign Selection
B12 = 0 Plastication RPM Profile Offset is Positive
= 1 Plastication RPM Profile Offset is Negative
B13 = 0 Plastication Pressure Profile Offset is Positive
= 1 Plastication Pressure Profile Offset is Negative
