EAC
Pressure Control Limits
Word Description
EAC41 Advance stroke Pressure Minimum Control Limit [03] Minimum controllable ejector-advance pressure attainable during any Press/
Pos Ejector Profile advance stroke. The module expects this ejector-advance pressure when setting its selected pressure advance
valve to the %- output in EAC43.
EAC42 Advance stroke Pressure Maximum Control Limit [03] Maximum controllable ejector-advance pressure attainable during any Press/
Pos Ejector Profile advance stroke. The module expects this ejector-advance pressure when setting its selected pressure advance
valve to the %- output in EAC44.
EAC43 Selected Pressure Advance Valve Output for Minimum [19] 0% CV output percentage that the module uses to drive the selected
pressure advance valve during any Press/Pos Ejector Profile. The module expects a pressure equal to EAC41 when setting the
selected pressure advance valve to this %-output during stroke execution. The Press/Pos Ejector Profile advance stroke will be
executed as a reverse-acting algorithm if this entry is greater than EAC44.
EAC44 Selected Pressure Advance Valve Output for Maximum [19] 100% CV output percentage that the module uses to drive the selected
pressure advance valve during any Press/Pos Ejector Profile. The module expects a pressure equal to EAC42 when setting the
selected pressure advance valve to this %-output during stroke execution. The Press/Pos Ejector Profile advance stroke will be
executed as a reverse-acting algorithm if this entry is less than EAC43.
Velocity Control Limits
Word Description
EAC45 Advance stroke Velocity Minimum Control Limit [10] Minimum controllable ejector-advance velocity attainable during any Vel/Pos
Ejector Profile advance stroke. The module expects this ejector-advance velocity when setting its selected velocity-advance valve to
the %-output in EAC47.
EAC46 Advance stroke Velocity Maximum Control Limit [10] Maximum controllable ejector-advance velocity attainable during any Vel/Pos
Ejector Profile advance stroke. The module expects this ejector-advance velocity when setting its selected velocity-advance valve to
the %-output in EAC48.
EAC47 Selected Velocity Advance Valve Output for Minimum [19] 0% CV output percentage that the module uses to drive the selected
velocity advance valve during any Vel/Pos Ejector Profile. The module expects a velocity equal to EAC45 when setting the selected
velocity advance valve to this %-output during stroke execution. The Vel/Pos Ejector Profile advance stroke will be executed as a
reverse-acting algorithm if this entry is greater than EAC48.
EAC48 Selected Velocity Advance Valve Output for Maximum [19] 100% CV output percentage that the module uses to drive the selected
velocity advance valve during any Vel/Pos Ejector Profile. The module expects a velocity equal to EAC46 when setting the selected
velocity advance valve to this %-output during stroke execution. The Vel/Pos Ejector Profile advance stroke will be executed as a
reverse-acting algorithm if this entry is less than EAC47.
Advance Stroke Tuning Constants
Word Description
EAC49 Proportional Gain for Pressure Control [30]
EAC50 Integral Gain for Pressure Control [27] or [28]
EAC51 Derivative Gain for Pressure Control [26] or [21]
EAC52 Proportional Gain for Velocity Control [28]
EAC53 Feed Forward Gain for Velocity Control [30]
EAC54 - 56 Open
Profile Pressure Alarm Setpoint
Word Description
EAC57 Profile High Pressure Alarm Setpoint [03] The module compares real-time ejector pressure against this entry when executing the
Ejector Profile. The module sets alarm status bit SYS06-B13 when ejector pressure equals or exceeds this entry during the Ejector
Profile. A zero entry inhibits SYS06-B13.
