Pressure Control Limits

Word

Description

LPC41

Pressure Minimum Control Limit [02] Minimum controllable clamp pressure attainable during any Clamp Low Pressure Close Profi-
le. The module expects this clamp pressure when setting its selected valve to the %-output in LPC43.

LPC42

Pressure Maximum Control Limit [02] Maximum controllable clamp pressure attainable during any Clamp Low Pressure Close
Profile. The module expects this clamp pressure when setting its selected valve to the %-output in LPC44.

LPC43

Selected Pressure Valve Output of Minimum [19] 0% CV output percentage that the module uses to drive the selected pressure
valve during any Clamp Low Pressure Close Profile. The module expects a pressure equal to LPC41 when setting the selected
pressure valve to this %-output during profile execution. The Clamp Low Pressure Close Profile will be executed as a reverse-act-
ing algorithm if this entry is greater than LPC44.

LPC44

Selected Pressure Valve Output of Maximum [19] 100% CV output percentage that the module uses to drive the selected pressure
valve during any Clamp Low Pressure Close Profile. The module expects a pressure equal to LPC42 when setting the selected
pressure valve to this %-output during profile execution. The Clamp Low Pressure Close Profile will be executed as a reverse-act-
ing algorithm if this entry is less than LPC43.

Profile Tuning Constants

Word

Description

LPC49

Proportional Gain for Pressure Control [30]

LPC50

Integral Gain for Pressure Control [27] or [28]

LPC51

Derivative Gain for Pressure Control [26] or [21]

Profile Pressure Alarm Setpoint

Word

Description

LPC57

Profile High Pressure Alarm Setpoint [02] The module compares real-time clamp pressure against this entry when executing the
Clamp Low Pressure Close Profile. The module sets alarm status bit SYS05-B15 when clamp pressure equals or exceeds this
entry during the Clamp Low Pressure Close Profile. A zero entry inhibits SYS05-B15.
