Set Profile Pressure Alarms
For Ram (Screw) Pressure – After spanning your pack and hold
pressure valve, set profile maximum pressure alarm setpoints PKC57
(N44:173) for pack and HDC57 (N44:233) for hold equal to a ram (screw)
pressure that should not be exceeded during either profile. Make sure
these values are not greater than the Maximum Pressure Control Limits:
PKC42 and HDC42. Entering a value of zero disables these alarms.
For Cavity Pressure – If using a cavity pressure sensor, set the
maximum cavity pressure alarm setpoints PKC58 (N44:174) for pack and
HDC58 (N44:234) for hold to a cavity pressure that should not be
exceeded during these profiles. Entering zero disables these alarms.
