B02-B07 Open
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 - PLC40
RESET, SYS15-B15 = 1, immediately begins the Post-decompression Movement
and PSC05 > 00000
RESET, SYS15-B15 = 1, sets its outputs to PSC33 - PSC40
and PRC05 = 00000
RESET and SYS15-B12 = 0 sets its outputs to zero and latches SYS13-B10
B09-B11 Open
