Pressure Limit Alarms
The module latches bits individually when executing a pressure-limited Vel/Pos Injection Profile and monitors a real-
time ram (screw) pressure equal to or greater than IPC57 during the subject profile segment. The module unlatches
each bit when it completes the segment without monitoring a real-time ram (screw) pressure equal to or greater than
IPC57.
This bit is
latched ON:

Injection Transition Status
B00
= 0 Normal
= 1 Injection Transition on Time
The module sets this bit when the Transition Time Setpoint (IPC60) triggered completion of last Injection Profile.
B01
= 0 Normal
= 1 Injection Transition on Ram (Screw) Position
Module sets this bit when Transition Ram (Screw) Position Setpoint (IPC61) triggered completion of last Injection Profile
B02
= 0 Normal
= 1 Injection Transition on Ram (Screw) Pressure
Module sets bit when Transition Ram (Screw) Pressure Setpoint (IPC62) triggered completion of last Injection Profile.
B03
= 0 Normal
= 1 Injection Transition on Cavity Pressure
Module sets this bit when the Transition Cavity Pressure Setpoint (IPC63) triggered completion of last Injection Profile.

IPS07
CV High Limit Alarms
The module latches each bit when executing the subject profile segment in closed loop, and drives its algorithm CV to
maximum (100%) in an attempt to control the profile setpoint.
The module unlatches each bit when it completes execution of the subject profile segment in open loop, or in closed
loop without driving its algorithm CV to maximum (100%).
When this bit
is latched ON:
