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.

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

PTC04

Open

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.

B07

Injection pressure valve output

B08 - B15

Reserved Do not use.

PTC09

Trace #2 selection

B01

Injection position

B02

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.
