Movement Set-output Values
When the module starts the Pre-decompression Movement, it:
• uses ramp rates PRC17-20 and PRC25-28 to ramp outputs
• sets its outputs to the values listed below
Word Description
PRC09 Output #1 Set-output Value during Movement [19]
PRC10 Output #2 Set-output Value during Movement [19]
PRC11 Output #3 Set-output Value during Movement [19]
PRC12 Output #4 Set-output Value during Movement [19]

Output Ramp Rates
The module uses the following ramp rates when moving its outputs
from setpoint to setpoint during the Pre-decompression Movement.
A ramp rate entry of zero gives a step function ramp (ramp disable).
Word Description
PRC17 Output #1 Acceleration Ramp Rate during Movement [20]
PRC18 Output #2 Acceleration Ramp Rate during Movement [20]
PRC19 Output #3 Acceleration Ramp Rate during Movement [20]
PRC20 Output #4 Acceleration Ramp Rate during Movement [20]
PRC21-24 RFU
PRC25 Output #1 Deceleration Ramp Rate during Movement [20]
PRC26 Output #2 Deceleration Ramp Rate during Movement [20]
PRC27 Output #3 Deceleration Ramp Rate during Movement [20]
PRC28 Output #4 Deceleration Ramp Rate during Movement [20]

End of Movement Set-output Values
When the module completes the Pre-decompression Movement and
HPC03-B09 is SET, it:
• sets status bit SYS22-B07
• uses ramp rates PRC17-20 and PRC25-28 when changing outputs
• sets its outputs to the following values
Word Description
PRC33 Output #1 Set-output Value at End of Movement [19]
PRC34 Output #2 Set-output Value at End of Movement [19]
PRC35 Output #3 Set-output Value at End of Movement [19]
PRC36 Output #4 Set-output Value at End of Movement [19]
PRC37-56 RFU
Movement Pressure Alarm Setpoint
Word Description
PRC57 Movement High Pressure Alarm Setpoint [01] The module compares real-time ram (screw) pressure against this entry during the
Pre-decompression Movement. The module sets alarm status bit SYS06-B06 when ram (screw) pressure equals or exceeds this
entry during the Pre- decompression Movement. A zero entry inhibits SYS06-B06.
