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.
LPC45 - 48 Open
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]
LPC52 - 56 Open
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.
