Description
Parameter for determining in which set of parameters a particular function is
active.
Time between the function picking up and tripping.
Pick-up current setting.
Forbidden settings: >2.8 I
N
Defines operation as overcurrent or undercurrent or with inrush blocking.Settings:
• MIN (3ph): Undercurrent. Three-phase functions detect the highest phase
current. Not permitted for single-phase functions.
• MIN (1ph): Undercurrent. Three-phase functions detect the lowest phase
current.
• MAX (3ph): Overcurrent. Three-phase functions detect the lowest phase
current. Not permitted for single-phase functions.
• MAX (1ph): Overcurrent. Three-phase functions detect the highest phase
current.
• MAX-Inrush: Blocks during inrush currents if one phase exceeds setting.
Defines whether single or three-phase measurement.
Defines the CT input channel.
All current I/P's may be selected.
Input for blocking the function.
• F: not blocked
• T: blocked
• xx: all binary inputs (or outputs of protection functions)
