PTC
End of Movement Set-output Values
When the module completes the Post-decompression Movement, it:
•
sets status bit SYS22-B09
•
uses ramp rates PSC17-20 and PSC25-28 when changing outputs
•
sets its outputs to the following values
Use these values for-pulling cores if applied before starting the first
clamp open profile.
Word Description
PSC33 Output #1 Set-output Value at End of Movement [19]
PSC34 Output #2 Set-output Value at End of Movement [19]
PSC35 Output #3 Set-output Value at End of Movement [19]
PSC36 Output #4 Set-output Value at End of Movement [19]
PSC37-56 RFU
Movement Pressure Alarm Setpoint
Word Description
PSC57 Movement High Pressure Alarm Setpoint [01] The module compares real-time ram (screw) pressure against this entry when ex-
ecuting the Post-decompression Movement. The module sets alarm status bit SYS06-B08 when ram (screw) pressure equals or
exceeds this entry during the Post-decompression Movement. A zero entry inhibits SYS06-B08.
PSC58 - 64 RFU
Bit-mapped Control Words
Word Bit Description
PTC01 Block ID = 00011100 (Low Byte). High byte reserved for the module. Do not use.
PTC02 Control bits
B00 0 = Process trace disabled
1 = Process trace enabled
B01 0 = Trigger on time delay
1 = Trigger on position
PTC03, 04 RFU
PTC05 Trigger delay (in hundredths of seconds) for data collection after injection begins
(when PTC02-B01 = 0)
PTC06 Trigger position (in hundredths of inches or tenths of millimeters) on which to collect data when PTC02-B01 = 1
PTC07 Sample rate at which the module collects trace data in milliseconds (must be an even number between 2 and 230)
PTC08 Trace #1 selection
B01 Injection position
B02 Injection pressure
B03 Injection velocity
The module will return unscaled injection position data if injection velocity is selected. The process trace screen uses
this position information to calculate and display velocity.
B04 Cavity pressure
B05 Screw RPM
B06 Injection flow valve output
B07 Injection pressure valve output
B08 - B15 RFU
PTC – Process Trace
Configuration Block
