Profile Pressure Alarm Setpoint

Word

Description

PKC57

Profile High Ram (Screw) Pressure Alarm Setpoint [01] The module compares real-time ram (screw) pressure against this entry
when executing the Pack Profile. The module sets alarm status bit SYS06-B02 when ram (screw) pressure equals or exceeds this
entry during the Pack Profile. A zero entry inhibits SYS06-B02.

PKC58

Profile High Cavity Pressure Alarm Setpoint [04] The module compares real-time cavity pressure against this entry when executing
Pack Profile. The module sets alarm status bit SYS06-B03 when cavity pressure equals or exceeds this entry during the Pack Pro-
file. A zero entry inhibits SYS06-B03.
