Profile Pressure Alarm Setpoint
Word
Description
INC57
Profile High Ram (screw) Pressure Alarm Setpoint [01] The module compares real-time ram (screw) pressure against this entry
when executing the Injection Profile. The module sets alarm status bit SYS06-B00 when ram (screw) pressure equals or exceeds
this entry during the Injection Profile. A zero entry inhibits SYS06-B00.
INC58
Profile High Cavity Pressure Alarm Setpoint [04] The module compares real-time cavity pressure against this entry when executing
the Injection Profile. The module sets alarm status bit SYS06-B01 when cavity pressure equals or exceeds this entry during the
Injection Profile. A zero entry inhibits SYS06-B01.
