Description

DYC02

Clamp Close Profiles Execution Commands
Bits DYC02-B00, -B01, -B02, -B03 are the four

action execution commands available to initiate all profiled Clamp Close

movements. The four Clamp Close Profiles may be logically linked as a single integrated machine movement if all three
of the Clamp Close Profiles Logical Bridge Bits are RESET. These three Logical Bridge Bits are as follows:
CPC03-B08 - Link First Close and Second Close
CPC03-B09 - Link Second Close and Third Close
CPC03-B10 - Link Third Close and Low Pressure Close
If all three of these bits are RESET, transfer only DYC02-B00 to the module to execute the entire Clamp Close portion of
an automatic machine cycle.

B00

= 0 Normal
= 1 Execute First Clamp Close Profile
A false-to-true transition of this bit forces the module to do

one of the following, attempted in the order listed.

if:

then the module:

any of SYS07-B00 through B05 are SET

ignores any profile commands

ejector position exceeds EPC63

latches alarm status bit SYS14-B08

either of the following are true:
– CPC03-B08 is SET and SYS15-B02 is RESET
– SYS15-B06 is RESET

latches SYS13-B01

If clamp position exceeds CPC61

and all within any box are true:

then the module:

– CPC11 is not zero
– clamp position exceeds non-zero entry in CPC11, CPC14, or CPC17

terminates any action in progress, and
starts First Clamp Close Profile (see note)

– CPC11 is zero or is not zero when clamp position is less than all

non- zero entries in CPC11,CPC14, and CPC17

– CPC03-B08 is SET

terminates any action in progress, and
sets outputs to FCC33 - FCC40 (see note)

– CPC11 is zero or is not zero when clamp position is less than all

non-zero entries in CPC11, CPC14, and CPC17,

– CPC03-B08 is RESET
– CPC20 is not zero
– clamp position exceeds non-zero entry in CPC20, CPC23, or CPC26

terminates any action in progress, and
starts Second Clamp Close Profile
(see note)

– CPC11 is zero or is not zero when clamp position is less than all

non-zero entries in CPC11,CPC14, and CPC17,

– CPC03-B08 is RESET
– CPC20 is zero or is not zero when clamp position is less than all

non-zero entries in CPC20, CPC23, and CPC26

– CPC03-B09 is SET

terminates any action in progress, and
sets outputs to SCC33 - SCC40 (see note)

– CPC11 is zero or is not zero when clamp position is less than all

non-zero entries in CPC11, CPC14, and CPC17

– CPC03-B08 is RESET
– CPC20 is zero or is not zero when clamp position is less than all

non-zero entries in CPC20, CPC23, and CPC26

– CPC03-B09 is RESET
– CPC29 is not zero
– clamp position exceeds non-zero entry in CPC29, CPC32, or CPC35

terminates any action in progress, and
starts Third Clamp Close Profile (see note)

– CPC11 is zero or is not zero when clamp position is less than all

non-zero entries in CPC11,CPC14, and CPC17

– CPC03-B08 is RESET
– CPC20 is zero or is not zero when clamp position is less than all

non-zero entries in CPC20, CPC23, and CPC26

– CPC03-B09 is RESET
– CPC29 is zero or is not zero when clamp position is less than all

non-zero entries in CPC29, CPC32, and CPC35

– CPC03-B10 is SET

terminates any action in progress, and
sets outputs to TCC33 - TCC40 (see note)

Note: If ejector position exceeds EPC63, the module ceases all action execution,

sets its outputs to zero, and sets alarm status bit SYS14-B08.
